Proposal: Verbose output from tests through decorators.

[kdexd]

Sometimes there are thousands of tests which may print too much on stdout or stderr. In that case, we need verbose output from ten of the tests. To facilitate this, we may introduce a marker for not capturing the output for certain tests.

Final mechanism can be as follows:

def test_foo():
    foo()
    print "foo called"

@pytest.mark.verbose
def test_bar():
    bar()
    print "bar called"

• Captured outputs can roughly be depicted as:

• py.test

  bar called

• py.test --capture=no

  foo called
bar called

• It may be taken up a step further to have verbose output from a module / directory recursion through pytest.ini support.

Another alternative is:

1. py.test (Everything captured)
2. py.test --capture=some (Marked tests will not be captured)
3. py.test --capture=no (All tests will not be captured)

Just FYI in pytest-3.0 capsys and capfd have a disabled() context manager method which disables capturing in the block:

def test_bar(capsys):
    with capsys.disabled():
        bar()
        print "bar called"

Thanks 😄 I am on 2.9 yet and was not aware about it ! Let's see where this discussion heads over, meanwhile I'll upgrade pytest and use this fixture.

3.0 is not out yet (will be out probably next week), sorry for not being clearer.

Also, I think your proposal is independent from the disabled() context manager and could be implemented as an alternative. 😁

Awesome 😃

I'm not sure if it's worth having yet another way™ to disable capturing in the core 😉

I guess if someone wants a marker like this, it'd probably be some 5-line hook in conftest.py to do it using capsys.disabled()?

Pytest 3 has been released and I have the feature what I wished to. Thanks, closing this. 😄
