Use in the new browse users system report, to which it is quite
specific. The filter itself is a like for like replacement of the
pre-existing filter on the same page, and is really a combination
of existing role/category/course filters.
We should respect the value of the PHPUNIT_LONGTEST constant in the
report source stress tests, as it was discovered after 165e26fa that
the default configuration of some CIs (GHA) was not sufficient to run
them.
Hence, use the PHPUNIT_LONGTEST to determine whether to execute said
tests. Note this constant is enabled on internal CI.
Implement stress tester methods for iterating over report columns,
aggregation and conditions. Assert that each works correctly in
isolation, and when used in conjunction with other columns.
Update existing entity to define remaining report elements. Add new
report source joining the entity to the user entity to provide data
for the reportbuilder editor.
