Post-mortem unit testing

Question

I do version control with Git, and unit testing with QUnit. Sometimes I find a bug in my software that was not present in a past version. It\'s easy for me to write a unit test

Answer 1

Use git bisect for this, please see this page.

Since you're testing JavaScript, you will probably have to run the tests by hand and run git bisect good and git bisect bad as appropriate. However, if you can run your unit test from the command line, then you can use git bisect run to have Git execute the test repeatedly and track down the faulty commit automatically:

$ git bisect run my-script.sh

That's pure magic the first time you see it! :-)
