Manual Mocking: Resisting the Invasion of Dots and Parentheses 232
The twittersphere has been all abuzz today because of something I tweeted early this morning (follow @unclebobmartin). In my tweet I said that I hand-roll most of my own mock objects in Java, rather than using a mocking framework like mockito.
The replies were numerous and vociferous. Dave Astels poignantly stated that hand-rolling mocks is so 2001!
So why do I roll my own mocks?
public class SelectorTest { private List<Object> list; @Before public void setup() { list = new ArrayList<Object>(); list.add(new Object()); } @Test public void falseMatcherShouldSelectNoElements_mockist() { Matcher<Object> falseMatcher = mock(Matcher.class); Selector<Object> selector = new Selector<Object>(falseMatcher); when(falseMatcher.match(anyObject())).thenReturn(false); List<Object> selection = selector.select(list); assertThat(selection.size(), equalTo(0)); } @Test public void falseMatcherShouldSelectNoElements_classic() { Matcher<Object> falseMatcher = new FalseMatcher(); Selector<Object> selector = new Selector<Object>(falseMatcher); List<Object> selection = selector.select(list); assertThat(selection.size(), equalTo(0));} private static class FalseMatcher implements Matcher<Object> { public boolean match(Object element) { return false; } } }
The first test shows the really cool power of mockito (which is my current favorite in the menagerie of java mocking frameworks). Just in case you can’t parse the syntax, let me describe it for you:
- falseMatcher is assigned the return value of the “mock” function. This is a very cool function that takes the argument class and builds a new stubbed object that derives from it. In mockito, the argument can be a class or an interface. Cool!
- Now don’t get all panicy about the strange parenthetic syntax of the ‘when’ statement. The ‘when’ statement simply tells the mock what to do when a method is called on it. In this case it instructs the falseMatcher to return false when the ‘match’ function is called with any object at all.
The second test needs no explanation.
...
And that’s kind of the point. Why would I include a bizzare, dot-ridden, parentheses-laden syntax into my tests, when I can just as easily hand-roll the stub in pure and simple java? How hard was it to hand-roll that stub? Frankly, it took a lot less time and effort to hand-roll it than it took to write the (when(myobj.mymethod(anyx())).)()).))); statement.
OK, I’m poking a little fun here. But it’s true. My IDE (InteliJ) generated the stub for me. I simply started with:
Matcher<Object> falseMatcher = new Matcher<Object>() {};
InteliJ complained that some methods weren’t implemented and offered to implement them for me. I told it to go ahead. It wrote the ‘match’ method exactly as you see it. Then I chose “Convert Anonymous to Inner…” from the refactoring menu and named the new class FalseMatcher. Voila! No muss, no fuss, no parenthetic maze of dots.
Now look, I’m not saying you shouldn’t use mockito, or any of these other mocking tools. I use them myself when I must. Here, for example, is a test I wrote in FitNesse. I was forced to use a mocking framework because I did not have the source code of the classes I was mocking.@Before public void setUp() { manager = mock(GSSManager.class); properties = new Properties(); } @Test public void credentialsShouldBeNonNullIfServiceNamePresent() throws Exception { properties.setProperty("NegotiateAuthenticator.serviceName", "service"); properties.setProperty("NegotiateAuthenticator.serviceNameType", "1.1"); properties.setProperty("NegotiateAuthenticator.mechanism", "1.2"); GSSName gssName = mock(GSSName.class); GSSCredential gssCredential = mock(GSSCredential.class); when(manager.createName(anyString(), (Oid) anyObject(), (Oid) anyObject())).thenReturn(gssName); when(manager.createCredential((GSSName) anyObject(), anyInt(), (Oid) anyObject(), anyInt())).thenReturn(gssCredential); NegotiateAuthenticator authenticator = new NegotiateAuthenticator(manager, properties); Oid serviceNameType = authenticator.getServiceNameType(); Oid mechanism = authenticator.getMechanism(); verify(manager).createName("service", serviceNameType, mechanism); assertEquals("1.1", serviceNameType.toString()); assertEquals("1.2", mechanism.toString()); verify(manager).createCredential(gssName, GSSCredential.INDEFINITE_LIFETIME, mechanism, GSSCredential.ACCEPT_ONLY); assertEquals(gssCredential, authenticator.getServerCredentials()); }
If I’d had the source code of the GSS classes, I could have created some very simple stubs and spies that would have allowed me to make these tests a lot cleaner than they currently appear. Indeed, I might have been able to test the true behavior of the classes rather than simply testing that I was calling them appropriately…
Mockism
That last bit is pretty important. Some time ago Martin Fowler wrote a blog about the Mockist and Classical style of TDD. In short, Mockists don’t test the behavior of the system so much as they test that their classes “dance” well with other classes. That is, they mock/stub out all the other classes that the class under test uses, and then make sure that all the right functions are called in all the right orders with all the right arguments. etc. There is value to doing this in many cases. However you can get pretty badly carried away with the approach.
The classical approach is to test for desired behavior, and trust that if the test passes, then the class being tested must be dancing well with its partners.
Personally, I don’t belong to either camp. I sometimes test the choreography, and I sometimes test the behavior. I test the choreography when I am trying to isolate one part of the system from another. I test for the behavior when such isolation is not important to me.
The point of all this is that I have observed that a heavy dependence on mocking frameworks tends to tempt you towards testing the dance when you should be testing behavior. Tools can drive the way we think. So remember, you dominate the tool; don’t let the tool dominate you!
But aren’t hand-rolled mocks fragile?
Yes, they can be. If you are mocking a class or interface that it very volatile (i.e. you are adding new methods, or modifying method signatures a lot) then you’ll have to go back and maintain all your hand-rolled mocks every time you make such a change. On the other hand, if you use a mocking framework, the framework will take care of that for you unless one of the methods you are specifically testing is modified.
But here’s the thing. Interfaces should not usually be volatile. They should not continue to grow and grow, and the methods should not change much. OK, I realize that’s wishful thinking. But, yes, I wish for the kind of a design in which interfaces are the least volatile source files that you have. That’s kind of the point of interfaces after all… You create interfaces so that you can separate volatile implementations from non-volatile clients. (Or at least that’s one reason.)
So if you are tempted to use a mocking framework because you don’t want to maintain your volatile interfaces, perhaps you should be asking yourself the more pertinent question about why your interfaces are so volatile.
Still, if you’ve got volatile interfaces, and there’s just no way around it, then a mocking framework may be the right choice for you.
So here’s the bottom line.
- It’s easy to roll your own stubs and mocks. Your IDE will help you and they’ll be easier and more natural to read than the dots and parentheses that the mocking frameworks impose upon you.
- Mocking frameworks drive you towards testing choreography rather than behavior. This can be useful, but it’s not always appropriate. And besides, even when you are testing choreography, the hand-rolled stubs and mocks are probably easier to write and read.
- There are special cases where mocking tools are invaluable, specifically when you have to test choreography with objects that you have no source for or when your design has left you with a plethora of volatile interfaces.
Am I telling you to avoid using mocking frameworks? No, not at all. I’m just telling you that you should drive tools, tools should not drive you.
If you have a situation where a mocking tool is the right choice, by all means use it. But don’t use it because you think it’s “agile”, or because you think it’s “right” or because you somehow think you are supposed to. And remember, hand-rolling often results in simpler tests without the litter of dots and parentheses!
Isn’t that a bit of a strawman example? I mean, in reality your going to write a lot more tests than 1, that needs that dependency. Then what are your options?
1. With the mockist approach, you’ll be doing one line changes in the tests to setup different expectations or returns. (ideally refactored into nice reusable methods)
2. Manually roll the mocks and end up with weird flag type objects to return different results or worse, lots of hand-rolled mocks of the same interface for different tests
You don’t even need to type
Matcher<Object> falseMatcher = new Matcher<Object>() {};
It’s enough to type
Matcher<Object> falseMatcher = new
and then press Ctrl+Shift+Space. IntelliJ will generate the anonymous inner class and stubs for all the methods that need to be implemented.
In Java it does not matter even if you don’t have the sources for some class. You can anyways extend the class/interface, because you have the .class files for it (otherwise you could not even compile). The lack of sources becomes a problem only when debugging or trying to understand how some third-party code works.
It’s not that the mock approach doesn’t test the behavior of the system. We test the behavior of the object we are currently testing. We test that the current object “dances” nicely by asserting that it obeys the contract of the interfaces it talks to.
We do it this way so that we only have to test the behavior of a class once, in one place. It is about DRY. Testing the behavior of our classes in more than once place is:
1) expensive – wasting cycles in our build, which we want to be fast so we can run it a lot.
2) allows the build to lie to us – More than one test failed, but only one behavior is broken. Which one?
3) brittle – when I change something multiple tests might have to change, whereas with the mock approach only two tests must change (The test that uses the mock interface, and the test that exercises the real implementation in the same way.)
The only disadvantage is the discipline implied by that last point. If I expect to be able to use an interface some way I had better assure that I have tested using the implementation the exact same way. Even in a strongly typed language I can’t rely on the compiler to force me to do that.
@Esko
>> You can anyways extend the class/interface
It’s not that easy, if It is a class you have to redefine each method so that the class acts as a mock (a lot of work), and sometimes (e.g. Spring MVC Controllers) the methods are final and you’re screwed.
I don’t think I understand how you can relate “how mocks are used” with “how mocks are provided”. Personally I use Moq for .Net and I cannot imagine going back to hand-rolling mock objects. Whether people use mocks to see how assemblies dance, or mock around behaviour is irrelevant to how you choose to mock.
Hand rolling is ridiculous when dealing with interfaces that have more than a couple methods defined within them, I don’t care how much the IDE fills in for me. That’s like saying “I don’t need Generics/Templates because the IDE/Resharper/CodeSmith can just generate what I need.” It just adds to the cruft that I have to skip over/ignore.
As for “dancing”, any checks a Mock does should be as simple and generic as possible. But asserting that key methods are called, and equally important “not” called in a given scenario is important. I.e. if in a normal path dependency A is called to perform an action, and you are asserting behaviour on an alternate path, then the mock can, and should report back a failure if that action is attempted when it shouldn’t have been.
Do what is simpler. In Bob’s example, hand-rolled is simpler. Other cases may be different. I don’t understand why this has to be a religious debate.
Dear Uncle Bob,
Take a look at RhinoMocks and AutoMocking container. It’s not Java so your arguments presented here don’t play out the same way in .NET. I find there is more work rolling your own, even with Resharper (what makes Visual Studio act like IntelliJ IDEA).
Let me know what you think.
Adam
Hi Bob
I appreciate the “what makes sense” approach of this post.
I think that too often we get carried away by shiny things, and forget that there may be less sexy, but more practical ways of achieving tasks.
I am a firm believer in doing what makes sense.
Having said that, I do like my rhino mocks in .NET ;-)
Regards, Joon
Great post, as usual!
A little footnote. I’m and “old style” tester, so I do not appreciate verbosity in tests that does not lead to better expressivity. So what is the advantage of
assertThat(selection.size(), equalTo(0));
compared to
assertEquals(0, selection.size());
???
It seems to me it would be helpful to keep concepts separate. As you point out, Uncle Bob, the example is a stub, not a mock. Mock frameworks exist to generate mocks, not stubs, but people use them for stubs anyway, mostly because they’ve gotten used to it. It’s a capability of mock frameworks that’s used because it’s there. You might argue whether it’s better to use the mock framework or not in specific cases, but the bottom line is the gain is marginal, if it exists at all.
It’s different if you need sensing. That means you need a mock or a Test Spy, and those are harder to hand-code.
On the other hand, spies are superior to mocks in every conceivable way as far as I can tell. That might give you additional incentive to hand code, since mock frameworks often aren’t capable of generating spies.
C’mon Bob, you can make the case better than this.
- as everyone has pointed out, this example is really about stubbing, so can we get the title right? - if I was doing this, I’d probably declare the FalseMatcher as a constant since it has no state. - on the other hand, I’m assuming you don’t care about which object is passed to the Matcher, since you don’t test that. Here it doesn’t matter, in other cases it might. - hand-rolled is only easier to read if you haven’t learned your tools (we’re all craftsmen, right?). How JUnit runs isn’t immediately obvious from the code, that’s why people get confused over when instances are created.
As we wrote in the book, testing external libraries is about the last place we’d use a mocking framework, unless we were really stuck.
@Dagfinn Of course I’m biased, but I can’t follow your line about spies and mocks. I find that spies don’t highlight the object relationships as clearly as I’d like, it’s harder to express sequence and state constraints, and they don’t force a failure until after the test is over.
When I first started doing TDD (.Net) I hand rolled all my mocks/stubs and that was great because I was just learning the basics of TDD. Introducing a mocking framework at that point would have only frustrated and confused me.
That being said, once I stopped to ask myself the question “There has got to be a better way…” I found RhinoMocks. I now use only a speckling of hand rolled mocks, but it is done to make my life easier. Hand rolling is great for specific scenarios where a mocking framework would over complicate stuff, but it tends to be the exception not the rule.
It is worth noting however, that there is still a chunk of “pre-RhinoMocks” test code filled with hand rolled mocks that is rarely touched. That at least speaks to what Bob was getting at when he said that our interfaces should rarely change.
Anyone who continues to think that using a mocking framework slows you down is living in the stone age. Sorry, that’s just the truth. Using a mocking framework does not slow you down, it speeds you up.
Look, using a mocking framework is not my religion, it is one of my disciplines. It’s like dual entry bookkeeping for accountants, or sterile procedure for surgeons. Professionals adopt such disciplines because they understand the theory behind them, and have directly experienced the benefits of using them.
I have experienced the tremendous benefit that using a mocking framework has had in my work, and I have observed it in others. I have seen and experienced the way that using a mocking framework helps programmers conceive their designs. I have seen and experienced the way it documents their decisions. I have seen and experienced the decouplings imposed by the tests, and I have seen and experienced the fearlessness with which people using a mocking framework can change and clean their code.
To be fair, I don’t think using a mocking framework is always appropriate. There are situations when I break the discipline and handroll mocks. I’ll write about these situations in another blog. However, these situations are few and far between. In general, for me and many others, using a mocking framework is a way to go fast, well, and sure.
The upshot of all this is simple. Using a mocking framework is a professional discipline. Using a mocking framework works. Using a mocking framework makes you faster. Using a mocking framework is not going away. And anyone who has not really tried it, and yet claims that it would slow them down, is simply being willfully ignorant. I don’t care if your name is Don Knuth, Jamie Zawinski, Peter Seibel, or Peter Pan. Give it a real try, and then you have the right to comment.
Let me put this another way. And now I’m talking directly to those who make the claim that using a mocking framework would slow them down. Are you really such a good programmer that you don’t need to thoroughly mock your work? Can you conceive of a better way to check your work than to express your intent in terms of an executable mock test? And can you think of a better way to ensure that you can write that mock test other than to mock it using a framework?
If you can, then I want to hear all about it. But I don’t want to hear that you handrolled a few mocks after the fact. I don’t want to hear that you manually check your code. I don’t want to hear that you do design and therefore don’t need to use a mocking framework. Those are all stone-age concepts. I know. I’ve been there.
So there.
@Steve Freeman: Thanks, I want opposition to the idea that spies are superior to mocks, since I haven’t really discussed it much. Do you have any examples that would make your position clearer? I admit I haven’t actively sought to compare the two side by side. What seems clear to me is that spies 1) can test anything a mock can test 2) make it easier to test complex objects that are passed to them, since it’s easier to test an actual object than to specify what you expect of a hypothetical object and 3) make for a more natural sequence in the test itself and lend themselves to refactoring to given-when-then.
Great comment by Reflective Surface.
Nevertheless, this was a balanced article from Uncle Bob. It seems that the experience of the TDD articles has led to this toning down of unsubstantiated claims from Uncle Bob. [Who says an old dog can’t learn new tricks? :-)]
One point that I’ve noticed with regards to mocks and spies, is that organizing the tests in a self-documenting way is easier with spies.
In a typical mock framework, you set the expectations for a mock in the test setup. When multiple tests use the same setup, then all of those tests fail when one of the expectations fails. So the tests are not isolated (http://agileinaflash.blogspot.com/2009/02/first.html) so that each test would specify only one behaviour, so that each test would have only one reason to fail. Also, the behaviour tested by the expectations is not immediately visible, unless the expectations are extracted to their own method (which is then called from the setup), which in turn makes the test code’s structure messy, and does not make the expectations visible in the test output the same way as all other test methods.
Here is an example of how I’ve written the same tests using Mockito (a spy framework) and EasyMock (a mock framework). Make a diff between these two to see the difference:
http://github.com/orfjackal/tdd-tetris-tutorial/blob/step7-done/src/test/java/tetris/RemovingFullRowsTest.java http://github.com/orfjackal/tdd-tetris-tutorial/blob/step7-done/src/test/java/tetris/easymock/EasyMockExample_RemovingFullRowsTest.java
In the EasyMock version there are lots of compromises that had to be made, in order to make the tests read like a specification:
- In the first two fixtures, the expectations had to be extracted to their own method and called from the setup, in order to make it clear that what is the behaviour being specified. This way it’s possible to see the intent when reading the test code, but it won’t be visible in the test output when the tests are run.
- In the last fixture, the test structure had to be reordered very much. In the other tests the “Arrange” and “Act” are done in the fixture setup, and each “Assert” is done in the fixture’s tests. But in this case the “Act” had to be moved away from the setup. Also an ugly comment was necessary.
In short, the use of a mock framework forces a different kind of style of testing on the programmer, so that writing tests in the preferred style is very hard or even impossible. But a spy framework makes it possible to write tests in the same state-based style as all the other tests, while at the same time getting the benefits of interaction-based verification.
A mock does verification. You’re not mocking, you’re stubbing.
I can see the benefit of rolling out manual mocks in very simple scenarios. however i do think that in most cases using a mocking framework actually increases the test readability: 1) As Steeve mentioned, anyone having minimal experience with any mocking framework will find the two tests equally understandable. And since mocking frameworks are useful all professional should posses such minimal understanding.
2) using a framework brings together the test and the fakes behavior, I found this improves my understanding of the test. I think it relates to the fact that this tends to make the test linearly readable (no need to jump to and back to the fake actual code)
Reflective Surface’s comment was NOT good. It was terrible. No one, not Bob and no one in the comments as far as I can remember (pretty busy right now, so may have missed/forgot one), said anything about using mocking frameworks making you go slower. It was about the expressivity of the test, and how using mocking frameworks often makes them look much uglier, and harder to read.
It depends. Sometimes hand-rolled stubs are easier, other times an isolation/mocking framework can save significant effort. Especially when you have to test behavior (I’d much rather test state, but sometimes you have to), a mocking framework will verify your assertions for you. I’ve hand-written mocks, and these classes can get out of hand quickly.
If your test has too many dots and parens, why not extract the mock creation out into a getFalseMatcher() method? That gives you the best of both worlds.
Along the lines of what Ben said – for simplicity, I like to create my own mocks/stubs when I’m testing Java code, but when I have the option, I like to create them in Groovy. Groovy makes mocking/stubbing so much easier and cleaner than Java, and allows you to use metaClass to pick and choose which methods to replace.
<grin>
The second test hides the nastiness inside a fake class called FalseMatcher … It is easy to refactor the first test into a method FalseMatcher() or something cool like Actor.FalseMatcher and hide in there the invation of dots and parenthesis. Eg refactor into FalseMatcher()
When doing .NET I use Rhino. I haven’t seen anybody talk about using dynamic mocks.
When TDDing JavaScript, I roll my own because of the use of closures. Functions being first-class definitely makes my life easier and less of a debate of using classicist/mockist.
@Reflective Surface Hats off to your choice of name: its irony only struck me as I finished typing this.
@Kyle Szklenski You Said: Reflective Surface’s comment was NOT good. It was terrible.
If your post is genuine, e.g. you are not the same person as Reflective Surface, or an accomplice of his, then note that his comment was obtained from Uncle Bob’s Echoes from the Stone Age post simply by replacing ‘TDD’ with ‘mocking’ framework.
Otherwise… Reflective Surface: I have just fallen victim to your artifice.
Oh, Bob…. http://bit.ly/2RAMoH
In The Art of Unit Testing, which according to Michael Feathers (who wrote the Foreword) is ‘an important title that should have been written years ago’, Roy Osherove, the author, says:
He also says:
@Franco Lombardo
Which assertion better communicates that ‘it is true that the selection size is zero’ ?
If we use
it reads as ‘it is true equals zero selection size’. Not too clear. Partly because ‘equals’ is used as a prefix operator, as in the LISP-like (= a b), and partly because the result operand comes before the computation operand, as in the LISP-like (= result computation).
If we use
it reads as ‘it is true that selection size equal to zero’. That is clearer. The equals is now in infix position, as in a = b, and the computation comes before the expected result: computation = result. But we can do better.
If we use
it reads as ‘it is true that selection size is equal to zero’, which is pretty much what we are trying to communicate.
Which one do you prefer?
As it says in this Hamcrest tutorial, the ‘is()’ matcher is pure syntactic sugar, to make your tests as readable as possible.
I think the comments point out clearly that this is a “religious” argument to some extent.
I use EasyMock very often, and I think I need to write more hand-rolled mocks / stubs. At the very least I need to try it and see how well it works for a given situation.
I certainly don’t agree with the assertion that boils down to “good programmers should be able to read code using mocks” (which is what I took away from Reflective Surface’s post). That’s as bad as saying “it was hard to write, so it should be hard to read.”
If a mediocre programmer can’t make sense of your code, then it could (and usually should) be written more clearly.
I really need to give Mockito a try, though. I’m not very keen on doing behavior-based verification unless I absolutely have to. My (admittedly stone-aged) mind finds it much easier to understand tests that verify state.
@Uncle Bob
In The Art of Unit Testing, Roy Osherove says:
Your test credentialsShouldBeNonNullIfServiceNamePresent conforms to this practice: it has one mock called manager, and two stubs called gssName and gssCredential.
Do you think it would enhance readability to have mock names contain ‘mock’, and stub names containing ‘stub’, like in the Apps flavour of Hungarian Notation?
e.g. 1: mockManager, nameStub and credentialStub
e.g. 2: mockManager, stubbedName and stubbedCredential.
We would then have:
This could also help to quickly check that there is no verification of methods called on stubs.
It is only the text, Which i can understood, however, programming code has just gone above my brain. Indeed, this would be a great idea to be used in Twitter.

This is just a nice sample code to learn on.
I really apprciate this. This is the best post that i read on this blog.
It depends. Sometimes hand-rolled stubs are easier, other times an isolation/mocking framework can save significant effort. Especially when you have to test behavior (I’d much rather test state, but sometimes you have to), a mocking framework will verify your assertions for you. I’ve hand-written mocks, and these classes can get out of hand quickly. longview real estate
If your test has too many dots and parens, why not extract the mock creation out into a getFalseMatcher() method? That gives you the best of both worlds.

I’m not very keen on doing behavior-based verification unless I absolutely have to. My (admittedly stone-aged) mind finds it much easier to understand tests that verify state.

Almost any situation--good or bad --is affected by the attitude we bring to. Adversity reveals genius; fortune conceals it. As fruit needs not only sunshine but cold nights and chilling showers to ripen it, so character needs not only joy but trial and difficulty to mellow it. Although the world is full of suffering, it is full also of the overcoming of it. tiffany and co outlet
