When we initialize an environment for some particular test case, we should put it as a fixture,
because we should make sure it will be run before the test case and cleaned after the test case (it should not mess the environment)

You missed one step:
"# entry to add WITH memberS and WITH the ACI -> ldap.INSUFFICIENT_ACCESS
# member should contain only one value"

It should be two steps, I think

It is not descriptive enough. Your tests are about SelfDN aci.
First, you should rename the file to something like "selfdn_permissions_test.py".
And each first line should be rewritten to something related.
"It checks that, bound as bind_entry" -> "Check add entry operation with and without SelfDN aci"

Once again, it should be fixture

You can add the tests to the existing test suite. I don't think we should split it into different places.

basicaly in this test case you check for valid and invalid values.
I think you can have just two steps. One will have all valid (mention each of them) and another invalid (negative and just chars)

Should be fixture

I think it is better to mention the attributes you set here.

It is for userpassword. nsslapd-pluginarg2: can have any attribute.

The same for the rest test cases here

Should be fixture

Add some verb here. Like 'check' or something

@spichugi Hey mate! have made the changes mentioned above, have a look.

We should mention all of the setup fixtures here. So if you add some 'init' fixture, describe it shortly here.

@spichugi it's done!
