release 3.8.0 - ModuleNotFoundError: No module named 'mock'

[dazza-codes]

After updating from pytest-mock 3.7.0 to 3.8.0, the following import error crashes the test suite:

  File "/opt/conda/envs/gis/lib/python3.7/site-packages/pytest_mock/plugin.py", line 33, in <module>
    import mock
ModuleNotFoundError: No module named 'mock'

Sorry about that, will work on a fix soon.

[nicoddemus]

Fixed, sorry for the regression!

ImportError while importing test module 'C:\GitHub\Design-Patterns-with-Python\05_Adapter_Design_Pattern\test_adapter.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:

    return _bootstrap._gcd_import(name[level:], package, level)

    from pytest_mock import mocker
E   ModuleNotFoundError: No module named 'pytest_mock'

Pytest version installed is 3.10.0. Why am i seeing this error?

No idea, but seems like something wrong with your environment.

I see you are using conda, try conda install pytest-mock instead.

[Amitabh1989]

I tried the same for the python prompt, and it works just fine!

## But down here, in same env, it just works fine.

@dazza-codes Given your stacktrace there pointing to:

pytest-mock/src/pytest_mock/_util.py

Lines 14 to 18 in 234e167

	use_standalone_module = parse_ini_boolean(
	config.getini("mock_use_standalone_module")
	)
	if use_standalone_module:
	import mock

it sounds like you configured pytest-mock via mock_use_standalone_module to do exactly that.
