It'd also make it easier to add an uncaptured pytest.print(msg) for easy printf-style debugging (without having to use -s and being greeted by a firehose of output). self.print_logs = get_option_ini(config, ' log_print ') We should call config.warn if self.print_logs (after accounting for command-line and ini option) is False . . But what’s the definition of a unit test? All features offered by the coverage package should work, either through pytest-cov’s command line options or through coverage’s config file. Nose never really fixed the boilerplate of unittests. . tests folder. If you need particular output, the doc page you mentioned offers few suggestions: Insert assert False, "dumb assert to make PyTest print my stuff" at the end of your function, and you will see your output due to failed test.
