Created multiple regression test runs from the same test suite and assigned a test run to each tester. Also, added custom fields e.g. Test Build Number, Operating System and Machine Details.
Tester A executes test run entered e.g. Test Build Number, Operating System and Machine Details.
Tester B executes test run but was able to overwrite all data that Tester A entered e.g. Test Build Number, Operating System and Machine Details Fields.
I thought the test suite is where you store all your base test cases, which you can reference and create multiple regression test runs. Each test run should allow a tester to input his/her own test data.
Please confirm if this is a defect that needs to be fixed ASAP.
