Unittests?
Manual testing is cumbersome
Automatedtesting isfast
Unit tests for the Realty Manager   extension
more than1600 tests
in less than 60    seconds
Verify that your codedoes what you expect
Make sure that yourchanges won‘t break           anything
Keep        other codersfrom breaking your code
Don‘t break anythingeven in complex projects
Create asafety net   for refactoring
Green feels good!
