Those tests either just check that an exception is NOT thrown or are
there to check dependencies for other tests. Newer phpunits mark all
tests as risky that have no assertion.

The filter passed by the user manager is called 'grps' not 'group'

This is a feature that was present in the old authmysql plugin. It
allows administrators to specify an SQL string that is used for explicit
password checking instead of letting DokuWiki compare the hashes. This
is useful where application implement their own salt/hashing thing.

This comes with a test case for the MyBB forum software. Dump kindly
provided by William Kitchen

This allows for more fine control over what the abilities are,
depending on the parameters used within the configured sql string.

this was an intermediate woriking state but got replaced by indivdual
dump skipping. forgot to remove it again

this allows for each dump being run within its own test case which then
can be skipped. This is needed to skip the django test on older PHP
versions.

this hopefully fixes the tests on travis

now all capabilities are covered

this makes sure manually assigned groups win on systems where only one
group is supported.

otherwise limit and offsets break in mysql

this configures a minimal wordpress setup
