Abehaviour and the implemented behaviour. It is therefore preferable to design these tests based on the specifications whatever they are prerequisites technical specifications stories rather than on the code itself otherwise we risk only validating the implemented behaviours which may differ from the expected behaviours The best way to avoid falling into this trap is to write the tests first using any test first approach for example in TDD Test Driven Development. When designing and writing unit tests it is a good idea to follow certain best practices or conventions.
Tests must be restricted in their functional scope do not attempt to validate things in a single test They must be quick to run no waiting time s in a unit test They must be automated no manual execution of unit Phone Number List has anyone really ever thought of doing Athat . Tests are clearly named and organised todays frameworks make it possible to perfectly organise tests and encourage you to choose relevant names e.g. describe CONTEXT... it SHOULD DO THIS Tests can be run on the developers workstation it must be possible to have a status of the unit tests without having to implement a complex mechanism of deployment server startup etc. test use case.
Ideally only one assertion per unit test this makes it possible to know right away what is wrong when a test is in error in real life we can afford several assertions to validate the boundaries of the same behaviour. The results of a unit test must be stable over time. The test that flashes a red shot a green shot is unreliable and must be modified or deleted The tests must be isolated and independent each test must be able to be executed alone and after or before any other test. Its proper functioning should not depend on the context provided by another test. Other practices however should be avoided Validating implementation details in a.
