Version Control and Testing

VC & testing work well.

• Run the tests, make sure they pass

• Make sure everything is checked in.

• Write tests for the bug / feature.

• Make sure they fail.

• Fix your bug / write your feature

• Run the tests.

• If they pass, commit. You're done.

• If they fail, look at the diff.
  • The problem is revealed by that change.
  • The bug is easier to find.
  • The smaller the change, the better this works.

You are using version control, right?
