login assertion: check for interrupted login

[colin-kiegel]

The login assertion currently only has a negative check, that it does not see the login form again. This will discover wrong credentials.

The assertions does not check for interrupted logins due to:

• request to change password
• request to accept user agreement

Reusability + out-of-the-box experience is a key goal of this testsuite.
But we don't know the startpage of other ILIAS installations.
Therefore it's hard to make a positive assertion for regular logins.

Suggestion

We could switch the login to a permanent login to the ILIAS repository goto.php?target=root_1&client_id=…. Then a positive assertion is possible without breaking the testsuite for other installations. However this would lead to different testresults (a permanentlinks adds another redirect).

The assertions could then be copy-pasted from the GET Repository testcase.

I think this is a good suggestion. However currently I would rate the stability of the testsuite running for 5.3 higher. We need a set of comparable results for the next few month. We should can tackle this in autumn.

If you think this will not impact the results (too much). I am completely in for it.
