Even in case of libraries and when they are not big like nova. It is better to use next rules: 1) structure of tests directory is the same as a root of project Tests directory will be well organized, and it will be simple to find where to write tests 2) names for end modules should be test_<name_of_testing_module>.py Change-Id: I069121c5f32bbe51c6795e51c23ff3630fcd43e2
