Test result rule name cut off

Yes, I have had this a few times and could not see any particular pattern. Is it worth linking the specific results here? Mine were fairly recent. I will get the links.

I don't think I have seen this problem for a while. If I do I will link to the results.

Here is an example from today of a core patch
https://www.drupal.org/pift-ci-job/461995

Is it caused by the fact that the name should start with a backslash, but it is not properly escaped? ... that somehow it evaluates \D which does not get displayed?

Working on the core parts here: #2810083: Duplicate test results per fail/exception

Also, in JunitXMLFormat.php there is :

        // Cleanup the class, and the parens from the test method name
        $test_method = substr($result['function'], strpos($result['function'], '>') + 1);
        $test_method = substr($test_method, 0, strlen($test_method) - 2);

These can probably be replaced with a preg replace.
Its currently expecting "Drupal\Tests\field_ui\FunctionalJavascript\EntityDisplayTest->testEntityView()"
But sometimes gets just "Drupal\Tests\field_ui\FunctionalJavascript\EntityDisplayTest" (which the causes the first character and last 2 chars to get cut off.)
Sometimes we get only the word 'Unknown' (Unknown becomes nkno because of these substrings).

so, better logic needed there.

We change it here. I changed it, its on a branch. When we move it into dev, then production it'll be fixed for all.

We can make a more isolated unit test of generateJunitXml() once #2823816: Always use the container-injected build, modify BuildTaskInterface::run() and ::start() to not pass $build is in and clarifies which build object is in control.

Im going to mark this as fixed, and open a follow up to add a test for the generated junit xml
