Test Driven Development Lab

  • Code twice deploy once :D

What I've learned

  • Automated testing basically means we write code to test the actual code of our application automatically, meaning we end up with Prod\Dev Code and Testing Code;
  • More time efficient than manual testing which involves launching the application, Login\register, navigate to desired page, populate fields and verify the result.;
  • You write them once and they're FREE to run anytime as we require!;
  • Bug are caught before deployment and when we deploy, we do it with confidence!;
  • Unit Tests test a single class or small unit of related classes (quick);
  • Integration Tests cover a greater range of the system by testing the application with it's external dependencies like DB CRUD operations(slow);
  • User Interface tests, which cover user interface from buttons to subsystems including database level (slower);
