For a successful run, expected and actual values are not shown and not stored as they would be same as what is defined on the testcase and can be referred from the testcase directly. Test results are instances of Data-TestCaseResults and are stored in its corresponding table. One can also see previous results on the testcase by clicking on View Previous Runs link on Test result banner on top of testcase. You could also run these tests using exposed REST service pzExecuteTests which returns the results in xUnit format and can be used for reporting purposes.
thanks vamshi for the help. i was able to find the results at a test case level, but was not able to find how many validations in each test case failed in the table associated with class Data-TestCaseResults. Can you provide some details about where can i find those details? is it a seperate table or stored in some other place? how can we retrieve them?
