Description
There seems to be an inconsistency with how ANSI escape codes for colored output are handled in the failure reason when using pytest.fail() with pytrace=True versus pytrace=False.
In the case where pytrace=True, the colored output is rendered correctly in the failure message. However, when pytrace=False, the ANSI escape codes are not processed, and they partly appear as raw text in the terminal output.
- minimal example if possible
Steps to Reproduce
from pytest import fail
def test_color_pytrace_true():
fail(reason="\n\x1b[34mThis should be blue\x1b[0m", pytrace=True)
def test_color_pytrace_false():
fail(reason="\n\x1b[34mThis should be blue\x1b[0m", pytrace=False)Expected Behavior:
For pytrace=True: The ANSI escape codes for blue text (\x1b[34m...) should render correctly, resulting in the phrase "This should be blue" being displayed in blue.
For pytrace=False: The ANSI escape codes should still render the text in blue.
Actual Behavior:
For pytrace=True: The colored output is handled correctly, and the text "This should be blue" is displayed in blue.
For pytrace=False: The ANSI escape codes are partly displayed as raw text ([34mThis should be blue[0m), and the text is not colored.
