How to write untestable code?

Test your code
- Choose automation
- Make it easy to test & modify
- Not test - No agile
  - Agile is out of reach if you don’t focus on tests
- Pay for testing

why we hate testing
- understanding of req is not clear. so no edge cover
- taking time more than implementation
- Not used to it
- having party in evening
- Yes we all kids

Best practice on test
- Don't test your implementation, Test your behaviour
  - Think you are testing one of public api
- Provide appropritate name for your test with domain / natual language / descriptive
- Diagnostics
  - assertTrue(a == 1); vs asertEquals(1,a);
  - asertEquals("Failed, Becoz we are not one",1,a);

TDD
write test before your implementation
dependency injection
Better OO code
