How to force change of environment variable to a specific value inside phpunit test?

Question

In my phpunit, I have this configuration:

<php>
    <env name="ENVIRONMENT" value="test"/>
</php>

I worked under the false assumption that he always set the environment variable to a value test. However, when the system already has a set of variables, it prefers an existing value.

$ export ENVIRONMENT=GNARF
$ phpunit -c test/phpunit.xml

Thus, inside the tests, the value env('ENVIRONMENT')will be "GNARF", although I expected "test".

Is there a way to force phpunit to view the parameter envnot as a default value, but as a specific value that it should use?

I would also like to avoid calling phpunit in a specific way to get the correct env variables.

So while this works:

ENVIRONMENT="test";./vendor/bin/phpunit -c tests/phpunit.xml

phpunit.xml, .
