We are trying to use the Pega-AutoTest agent for automated testing in Pega 6.2. We have a scheduled unit test suite which is picked up by RunTestSuitesFromAgent agent. We have configured a test application, test access group and test user. The test access group has the roles: PegaRULES:AutoTest and PegaRULES:SysAdm4. We have a test user which has this test access group as default acccess group. This test user is set as the user id for agent processing under the unit test suite. The agent picks up the scheduled unit test suite, however the test cases are not executed. Via tracing, I saw that there is a failure in the processing and the details of the failure are: Authentication modification permitted via privileged path only - invalid caller: RULE-OBJ-ACTIVITY RULE-AUTOTEST-CASE RUNTESTSUITEFROMAGENT. As I see, the failure happens at the step where the activity SetUserSecurityProfile is called from the activity BatchLogin, which is called by the activity RunTestSuiteFromAgent. Could you please help me with solving this issue?
