I'm waiting response about testlink's forum registration..I sent request 5 day ago...
New custom fields not available on existings test cases.
Why not ask users about action to do on existing testcase and, if it's required, a default value to set new field for existing testcases?)
No "regression test" management.
Mandatory test assigment to tester: no roundrobin about executing test.
No user (tester..) groups.
No mode to ensure only one test excecution.
No information about how link testcase vs ticket on BST.
Maybe I can to it only in test execution, I don't found anything about "...this testcase is related with these tickets on BTS..."
No clear information about what I can do on my BTS via testlink integration and viceversa..
