checkbox is not updating with status popups when moving from camera tests to cpu tests

[Jeff Lane ]

Durng cert runs I noticed that when going from the camera tests to the CPU tests, the checkbox UI will show the last camera test after it's started the cpu_scaling_test script.

This only seems to happen on the first automated test. ONce that one finishes and checkbox moves on to the cpu/clocktest script, a popup appears to indicate that something else is going on. Likewise with frequency_governors test.

This is the desktop when that first test starts running. Notice the terminal...pstree shows fwts is running for the cpu_scaling test, but the checkbox UI shows the last Camera test that was run, and the UI doesn't look busy, it looks like it's waiting for user input.

This is the desktop after the second automated test fires, and the popup finally appears...

I looked at the code, and the problem comes from automated tests not hitting the part of the code where the window's title is being set. So it will always reflect the last *manual* test that was run.

checkbox_gtk.py has a show_test method which shows the text for a manual test, this is where we currently update the window's title. However as I mention this only gets used on manual tests. This gets called from the manual_test.py plugin and it's easy to put the test's name because we receive a "test" object as a parameter.

Automated tests basically show the progress indicator (method show_progress_start) which is called from shell_test.py plugin, but unlike manual_test, it sends a preformatted string to display (something like "Running %s...") - this is because the progress indicator can also be used in a non-test context (i.e. launchpad upload progress or data gathering) and so a "test" object isn't always present.

The best solution I could find is to reset the window title to its default, not showing the test name, *after* we complete a manual test. This way, if a manual test is being run, its name gets displayed on the window title. If an automated test is running, the window title is by default "System Testing" and the test's name gets displayed on the new, spiffy in-dialog progress bar. This way there's always information about which test is being run, without duplicating it by showing both in the progress bar and in the window's title. I tested this solution and it's slightly inconsistent UI-wise, but nowhere near as confusing as the described behavior :)
