如何显示为什么在使用 py.test 时跳过了某些测试？

Question

I am using skipIf() from unittest for skipping tests in certain conditions.

@unittest.skipIf(condition), "this is why I skipped them!")

How do I tell py.test to display skipping conditions?

I know that for unittest I need to enable the verbose mode ( -v ) but the same parameter added to py.test increase the verbosity by still does not display the skip reasons.

Answer 1

When you run py.test, you can pass -rsx to report skipped tests.

From py.test --help :

-r chars            show extra test summary info as specified by chars
                    (f)ailed, (E)error, (s)skipped, (x)failed, (X)passed.

Also see this part of the documentation about skipping: http://doc.pytest.org/en/latest/skipping.html

Answer 2

Short answer:

pytest -rs

This will show extra information of skipped tests.

Detailed answer:

To complement @ToddWilson's answer, the following chars have been added: p and P ( 2.9.0 ), a ( 4.1.0 ) and A ( 4.5.0 ). The detailed information about skipped and xfailed tests is not shown by default in order to avoid cluttering the output. You can use the -r flag among with the following chars:

• ( f )ailed
• ( E )rror
• ( s )kipped
• ( x )failed
• ( X )passed
• ( p )assed
• ( P )assed with output
• ( a )ll except passed (p/P)
• ( A )ll.

Warnings are enabled by default, and the default value is fE .
