When a Behat test contains the step like

And I enrol "Studie One" user as "Student"

in non-javascript session, the step fails with error

"Field matching locator "'Assign roles'" not found."

This is a regression of MDL-53381 commit eb9ca848. In the previous version, there were chained steps that contained steps:

$steps[] = new Given('I set the field "' . get_string('assignroles', 'role') . '" to "' . $rolename . '"');

and

$steps[] = new Given('I set the field "' . get_string('assignrole', 'role') . '" to "' . $rolename . '"');

for javascript and non-javascript, respectively. Note the difference in the string identier "assignroles" (js) and "assignrole" (non-js).

rajeshtaneja did not notice this tiny difference (no surprise) and replaced both chained steps with single API call using the "assignroles" identifier. Which causes the step to fail in non-js session.

This was not discovered so far because no core test uses this step in non-javascript session.
