Tox failed but running the test in tox-created venv passed
by li.tiancheng＠gmail.com Jan. 29, 2020

Anyone has ideas on why running `tox` fails but running the same test in the tox-created venv passed? Here is an example test: metrics.py ``` def get_test_value(): return {1 : 'd', 2: 'e'} def _test_func(): metrics = get_test_value().values() metrics = [info for info in metrics] return metrics ``` metrics_test.py: ``` from metrics import _test_func class TestMetrics(unittest.TestCase): def test_example(self): return_value1 = {'metric_func_name': 'a'} return_value2 = {'metric_func_name': 'b'} expect(target).get_test_value.once().and_return({ 'test1': return_value1, 'test2': return_value2, }) self.assertEqual(_test_func(), [return_value1, return_value2]) ``` This test fails half of the time because the order can change: ``` E AssertionError: Lists differ: [{'metric_func_name': 'b'}, {'... != [{'metric_func_name': 'a'}, {'... E E First differing element 0: E {'metric_func_name': 'b'} E {'metric_func_name': 'a'} E E - [{'metric_func_name': 'b'}, {'metric_func_name': 'a'}] E ? ^ ^ E E + [{'metric_func_name': 'a'}, {'metric_func_name': 'b'}] E ? ```

Platform Specification custom environment
by Sergio Soldado Jan. 9, 2020

Jan. 9, 2020

Hi All, First of all I am a newb so please be gentle. I want to add a platform specific command to commands_pre. I followed the example so my tox.ini looks something like the following: ``` [tox] minversion = 2.0 envlist = full-{linux,macos,mswin}, nightly-{linux,macos,mswin} skipsdist = True [testenv] # environment will be skipped if regular expression does not match against the sys.platform string platform = linux: linux macos: darwin mswin: win32 commands_pre = linux: -bash -c 'some command here' [testenv:myspecificenv] commands = {[testenv]commands} -k myspecificenv ... ... The issue is that tox is being invoked with tox -e myspecificenv And this doesn't pick up the platform and this doesn't run the platform specific pre command. I am probably looking at this wrong so please help. Thanks, Sergio.
