I have run into this problem a few times now, and I was hoping there is a solution to it, that I haven't found out: Maybe you can help me out:
I usually plan the larger Testruns assigning several hundred Testcases to a team of 10+ Testers. They would work on their Testcases only. Now it has happened that a Tester accidentally clicked to "Assign to -> Me" Button on top of the Testcase list, because they wanted to filter the Testcases instead to show up only their Testcases.
The result was a very bad situation: All the Testcases were assigned to a single Person, the other Testers were not able to continue working on their share, and it took interruption and extra time to re-assign all the Testcases back to the original scenario.
I know, they should be able to read the difference between "assign" and "filter", but apparently, its easy to do that mistake.
My question then is: Is it possible to deny the Role "Testers" the use of that "Assign-Button"?
