Given a Test Suite id, is it possible to change the outcome of the test cases within it in Tfs ?
For instance , changing the active state to pass state or to failed state.
While iterating through the test cases with a test suite, i couldnt find a field by the name outcome. How can we modify the outcome field?
Seems you want to update the test result. You need to get the test run ID first.
You can use the REST API to update the specific test result. Please see Update test results for a test run for details.
You can also use TFS API, for example:
