How can I see normal print output created during pytest run?

Question

Sometimes I want to just insert some print statements in my code, and see what gets printed out when I exercise it. My usual way to \"exercise\" it is with existing pytest t

Answer 1

Try pytest -s -v test_login.py for more info in console.

-v it's a short --verbose

-s means 'disable all capturing'

Answer 2

pytest --capture=tee-sys was recently added (v5.4.0). You can capture as well as see the output on stdout/err.

Answer 3

You can also enable live-logging by setting the following in pytest.ini or tox.ini in your project root.

[pytest]
log_cli = True

Or specify it directly on cli

pytest -o log_cli=True

Answer 4

The other answers don't work. The only way to see the captured output is using the following flag:

pytest --show-capture all

Answer 5

According to pytest documentation, version 3 of pytest can temporary disable capture in a test:

def test_disabling_capturing(capsys):
    print('this output is captured')
    with capsys.disabled():
        print('output not captured, going directly to sys.stdout')
    print('this output is also captured')

Answer 6

When running the test use the -s option. All print statements in exampletest.py would get printed on the console when test is run.

py.test exampletest.py -s
