“So, you managed to pick stories that only involved changing data…”

“Yep.”

Great, there’s no need to test it, right?

Therefore, testing Java classes is unnecessary.

The JVM simply reads files in a particular format (the Java Class format)
The JVM processes those files
Java class files are just data to the JVM
Java source files are just data to the Java Compiler to generate data used by the JVM
We do not need to test data changes
Therefore we do not need to test Java classes.

q.e.d.

I ran across this years ago on a project that put business rules in the database so they could be easily changed. Without testing. Without versioning. “But it’s just data!”

Anything that changes the behavior of the system needs testing and versioning.

Backup iPhone SMS over 3 years later:

Keep your Contacts and SMS safe! Actually, the contacts and SMS have more values than a cell phone’s own value. You can pay money to buy a new iPhone, but cannot buy your lost contacts and SMS back. So it’s important for you to backup your contacts and SMS in iPhone. And we recommend you backup contacts and SMS regularly. Our backup software can help you take a snapshot for your contacts and SMS. Your important personal information will be never lost.
