1. Test should not leave the function context. ** Most important **
2. Test should verify the calls to methods / functions with side effects
3. Test should have descriptive names ( alterative to this is BDD )
4. Function and methods should only get the inputs that are essential to test functionality.
5. Test should be per function / method not per module / class. ( You can couple tests based on functionality )
6. Test should focus on branch coverage than LOC.
