Is there a way when using test manager to stop a test part of the way through close down test manager and continue the run at a later date with the attachments you have taken?
You can pause the test run, then save and close. All the attachments you've created to that point will be saved.
When you're ready to come back to the test, you'll need to return to the point you left and located the unfinished run (Test > Analyze Test Runs), then Resume.
You should be able to pick up where you left off.
