record_xml_attribute is an experimental feature, and its interface might be replaced by something more powerful and general in future versions. Pytest captures your output and your logging to display it only when your test fails. It's not about a comparison to the exception's message. All you need to do is to declare logs in your test arguments, it works just like any other fixture. Using pytest.raises is likely to be better for cases where you are testing exceptions your own code is deliberately raising, whereas using @pytest.mark.xfail with a check function is probably better for something like documenting unfixed … For pytest. Need py.test to log assert errors in log file from python logging module. Then you will see the test output and the test logs … I used assert statements through out the test. There are two ways to handle these kind of cases in pytest: Using pytest.raises function. Save the logs generated during a pytest run as a job artifact on GitLab/GitHub CI. message is actually used for setting the message that pytest.rasies will display on failure. For example: For example: from pytestqt.qt_compat import qt_api def do_something (): qt_api . The browser may run locally or remotely depending on your configuration, and may even run headless. The pytest-selenium plugin provides a function scoped selenium fixture for your tests. ... pytest.register_assert_rewrite ... Return captured log lines, if log capturing is enabled. No capturing of writes to filedescriptors is performed. There are three ways in which pytest can perform capturing:. fd (file descriptor) level capturing (default): All writes going to the operating system file descriptors 1 and 2 will be captured.. sys level capturing: Only writes to Python files sys.stdout and sys.stderr will be captured. qWarning ( "this is a WARNING message" ) def test_foo (): do_something () assert 0 But when encounter assertion errors, those messages are not logged in the python logging output but in command console. The functionality per-se will be kept, however. It's not a bug, it's a feature (although an unwanted one as far as I'm concerned) You can disable the stdout/stderr capture with `-s` and disable the logs capture with `-p no:logging`. Setting capturing methods or disabling capturing¶. Using pytest.mark.xfail decorator. This is useful for when you want to assert on the contents of a message: def test_baz(caplog): func_under_test() for record in caplog.records: assert record.levelname != 'CRITICAL' assert 'wally' not in caplog.text For all the available attributes of the log records see the logging.LogRecord class. I just wanted to correct a common mistake in this comment since it was one of the first results from my google search. Assert that two numbers (or two sets of numbers) are equal to each other within some tolerance. Using this over record_xml_property can help when using ci tools to parse the xml report. pytest-qt automatically captures these messages and displays them when a test fails, similar to what pytest does for stderr and stdout and the pytest-catchlog plugin. Warning. Published Oct 17, 2019 by Timothée Mazzucotelli While I was writing tests for one of my latest project, aria2p, I noticed that some tests that were passing on my local machine were now failing on the GitLab CI runner. In this post, I’m going to describe my method for getting around pytest’s output capture mechanism, so that I can see my debug print/logging statements in real time. Then you just check (using assert, as usual with pytest) if a specific line is in the logs … New … As the documentation says:. However, some parsers are quite strict about the elements and attributes that are allowed. This means that any test with selenium as an argument will cause a browser instance to be invoked. The test has python logging module set up and all logs goes there as expected. There are many circumstances where it’s really great to display the output of a test while a test is running, and not wait until the end. My favorite documentation is objective-based: I’m trying to achieve X objective, here are some examples of how library Y can help.
