Run code coverage without a phpunit.xml
staabm opened this issue · comments
when I don't have a phpunit.xml running a command like
vendor/bin/phpunit tests/library/UrlHelperTest.php --coverage-text
returns "No filter is configured, code coverage will not be processed"
$ vendor/bin/phpunit tests/library/UrlHelperTest.php --coverage-text
PHPUnit 10.5.19 by Sebastian Bergmann and contributors.
Runtime: PHP 8.2.12
........ 8 / 8 (100%)
Time: 00:00.020, Memory: 12.00 MB
There was 1 PHPUnit test runner warning:
1) No filter is configured, code coverage will not be processed
WARNINGS!
Tests: 8, Assertions: 8, Warnings: 1.
I wonder whether we could/should imply the coverage filter to be the paths which are passed to the CLI command, when no phpunit.xml exists in this case
The --coverage-filter CLI option exists for this purpose. Are you saying that it does not work or that you did not know about it? ;-)
I did not know about this option - thank you.
Also I wondern, when I run only a subset of the test-suite (which I do because I pass concret paths to tests to phpunit), whether it could just create coverage for these tests involved, without asking me to repeat a coverage filter (I already told with --coverage-html=coverage that I wan't coverage). might be helpful from a DX point of view.

One has nothing to do with the other.
Closing this as the problem was already solved (--coverage-filter exists).

I totally agree. let me re-phrase the idea from a end-user perspective.
I run vendor/bin/phpunit tests/library/UrlHelperTest.php --coverage-text because I want to run this particular test and want a coverage report which code was executed because of this test.
since UrlHelperTest.php declares CoversClass via metadata, I think PHPUnit "could find" via the metadata which classes it needs to generate coverage for, without me additionally adding a filter...?
I do not think that this would be useful, sorry.
