Issue

1) Running without deprecation details (works fine)

Running phpunit without displaying deprecations details works as expected.

make phpunit-without-deprecation-details

2) Run with enabled deprecations:

First naiv approach to enable deprecations.

• phpunit.displayDetailsOnTestsThatTriggerDeprecations="true"
• phpunit.source.ignoreSuppressionOfDeprecations="true"

make phpunit-with-some-deprecations

BUT the deprecation baseline (some-deprecations-baseline.xml) does not contain silenced deprecations. Running the same command using the generated baseline will cause output of silenced deprecation:

make run-phpunit-with-some-deprecations-baseline

3) Run with additionally enabling ignoring suppression of PHP warnings.

I checked a bit the code and I stumble over the fact if I ignore PHP warnings in the phpunit configuration file then the silenced deprecations also end up in baseline file:

make phpunit-with-all-deprecations

Running the same command against that generated baseline will not show any deprecations anymore.

make run-phpunit-with-all-deprecations-baseline
