1752315 - running |mach mochitest --appname path/to/firefox test_name.js| fails with AssertionError in getActiveTests assert pathAbs.startswith(self.testRootAbs)

Status: NEW

(Testing :: General, defect)

Description

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

It has been some time since I ran mozilla-central mochitests locally on Windows 8.1.

mach clobber
mach configure
mach mochitest --appname /f/Ablage/Temp/Trash/fx-useragent/firefox.exe browser_navigator.js

This fails with

0:52.88 INFO Checking for ssltunnel processes...
0:53.06 INFO Checking for xpcshell processes...
Error running mach:

['mochitest', '--appname', 'f:/Ablage/Temp/Trash/fx-useragent/firefox.exe', 'browser_navigator.js']

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.
You can invoke |./mach busted| to check if this issue is already on file. If it
isn't, please use |./mach busted file mochitest| to report it. If |./mach busted| is
misbehaving, you can also inspect the dependencies of bug 1543241.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

The severity field is not set for this bug.
:ahal, could you have a look please?

[Andrew Halberstadt [:ahal]]

Does this also happen without --appname?

Comment 3

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

This fails because something is missing from the object directory:

1. mach clobber && mach build && mach mochitest browser_navigator.js succeeds.
2. mach mochitest browser_navigator.js --appname /f/Ablage/Temp/Trash/firefox/firefox.exe afterwards succeeds.
3. mach clobber && mach configure && mach mochitest browser_navigator.js --appname /f/Ablage/Temp/Trash/firefox/firefox.exe fails.
