How to: Add a Comment while Running a Test
While you run a test using Test Runner, you have the option to add comments to the test steps. The comments can be used to relay specific details that you want to communicate to other team members regarding unexpected behavior, or suggestions about what to look for while you test an application.
The comments can be useful as supporting material related to bugs, for isolating code defects, or for refining user interface designs. For more information, see How to: Submit a Bug using Test Runner.
