Test Review Guidelines

A more elaborate and always up-to-date version of these guidelines can be found at http://www.artofunittesting.com/Test_Review_Guidelines

Make sure the test does not contain logic or dynamic values 178
Make sure the test tests one thing only 179
Make sure that unit tests are separated from integration tests 180
Check coverage by playing with values 180
Make sure that testing private or protected methods is not the norm (public is always better) 182
Make sure there is little to no duplication of code in the tests 184
Make sure setup and teardown methods are not abused 188, 214
Make sure tests are completely isolated and repeatable 191
Make sure that most tests only have one assert 198
Make sure tests are not over-specified 205
Check for good naming conventions 210-211
Make sure that only meaningful assert messages are used 212
Make sure asserts are separated from actions 214

Make sure that state-based testing is preferred and used over interaction testing 83
Make sure strict mocks are used as little as possible 106
Make sure there is only one mock per test 94
Make sure the test calls “Verify” or assert on one mock and not on all fake objects in the test (or it might be testing more than one thing) 123
Make sure that only in rare cases a stub is also a mock at the same time in the same test 84
