Provide a test folder (./<rootfoldername>/specs/test)

As the name suggests, this is where you SHOULD store your tests. As with the src folder, you SHOULD place test projects in sub folders, mapping the name of the sub folder to the name of the project.

Names SHOULD correspond to those of your dependency layers, with the .Tests suffix added.

When writing the tests, you SHOULD:-

• Prioritise output testing over testing that assures modules.

• Adopt Behavioural Driven Development as your approach.

• Balance the benefits and drawbacks of adding extensive testing to your solution.

• Consider You Aren't Gonna Need It (YAGNI) rules when deciding what to test.

• Consider the testing requirements described in your Definition of Done (DOD).

Consider wider assurance needs when deciding what tests to write. Integration and smoke tests often provide the greatest benefit Consider You Aren't Gonna Need It (YAGNI) and carefully balance the time and effort of an extensive testing approach with the benefit it provides
