Key points
| Tool | When to use it |
|---|---|
| The terminal | A quick run, or an automatic run on a server |
| HTML report | To summarise a run: what passed, what failed, and (roughly) why |
| Trace Viewer | To investigate a failure in depth, even after the run ended and on another machine |
| UI Mode | To develop and fix tests while you work |
Rule of thumb
Work in UI Mode, summarise in the report, and investigate a remote failure in Trace Viewer.
