pytest selenium output flooded with debug logs

Question

What's Happening

I'm writing acceptance tests with selenium-python and pytest on python 2.7. Whenever a test fails the CLI output is flooded with debug output under ---captured log call--- for every failed test.

Example

That's for 1 test failure! When I have N failures, this debug output is multiplied for every test. Compared to the 10-20 lines pytest outputs showing my failed test and the exception raised, this is both needlessly verbose and time-consuming to search through.

Running in quiet mode doesn't remove this output either.

pytest tests/acceptance/pricers/test_fxfwd.py -q

or running with multiple flags of -q...

How then do I remove this debug output or otherwise prevent it from being displayed for failed tests?

Answer 1

You can confirm this in your pytest.ini like this.

[pytest] 
log_print = False

You can also add log_format options to send different log levels to different files , you will at some point want to see those logs.

For the full options and more background the docs are here https://docs.pytest.org/en/latest/logging.html

If the file is not present, add pytest.ini in the root directory of your test suite.
