This Behat scenario should be working fine even without the "@javascript" tag. However, for some reason, removing the "@javascript" tag causes random failures.

Also, the run time of this scenario is unnecessarily long and can be further shortened by directly setting "$CFG->maxediting" time to "1 second" using the "the following config values are set as admin:" step. This will enable the user to simply wait for 2 seconds after creating the discussion in order to quickly verify the editing expiry and will greatly decrease the test execution time.

To reproduce:

1. Apply the patch in this issue (e.g. in master)

   git checkout master && git pull git://github.com/junpataleta/moodle.git MDL-67778-master

2. Initialise Behat
3. Download behattest.sh to your moodle root folder. It's a script that repeatedly runs the "Time limit expires" scenario for 100 times.
4. Go to your moodle root folder and make it executable

   chmod +x behattest.sh

5. Run the "behattest.sh"

   ./behattest.sh

6. Expected
   • All tests should pass up to the 100th iteration.
7. Actual
   • The Behat test randomly fails.
