We should make the jit-tests harness runnable on mobile, similar to how we have
Duplicate of this bug: 900098
I've been working on similar things for c++ unit tests, I'll take a look at this one as well.
Terrence and I worked on something this week. The patch needs a bit of final polish and testing on a panda, but should be ready early next week.
Assignee: general → dminor
I'm getting a large number (~300) of failures when running the jit-tests on my panda board. I've attached a log file from one of my runs.

As far as I can tell, the paths are correct and no files are missing, but I'm wondering if I'm running tests I should be excluding or if I'm missing some options.

Is there any other output? it looks like all of the output we're getting for most tests is 'r\0Exit code: 0', and exit codes of 0 are usually a good thing.  I'd guess that the issue is either a bit of garbage being printed to stdout, or just reading the wrong return code at some point in time.
I looked at a random failure (bug617485.js), and it appears that it's supposed to fail with a syntax error, which suggests to me that perhaps however you're running the test is not taking this annotation into account:

// |jit-test| error:SyntaxError

That's the first line of the test js file. The corresponding output in the log:

/data/local/tests/js-jit-tests/js -f /data/local/tests/js-jit-tests/jit-tests/lib/prolog.js -e "const platform=\"linux2\"; const libdir=\"/data/local/tests/js-jit-tests/jit-tests/lib/\"; const scriptdir=\"/data/local/tests/js-jit-tests/jit-tests/tests/auto-regress/\"" -f /data/local/tests/js-jit-tests/jit-tests/tests/auto-regress/bug617485.js

Thanks for the pointers. I'll take a look at the check_output function and look for parse issues with data coming back from the device and/or missing test annotations. The majority of the tests are passing, so this hopefully is a small problem.
The problem was that I was only getting stdout from the remote device, but check_output expects the error to be on stderr. I'll work around this.

Filed bug 906525 to fix intermittent failures I hit when running on my pandaboard.
Attached patch bug-858622-fix.patch (obsolete) — Splinter Review
Total running time using the SUT agent is around 20 minutes, including about 3 minutes to push the files to the device. I've left ADB support in, but it is unusably slow due to how the files are pushed to the device under ADB. SUT is what is used in production, but please let me know if we need to make ADB work for local testing and I will file a follow up bug.

Could we call this deviceTransport to match the other options?

Thanks for the review. With comments addressed:
Everybody else was happy enough with it, but Windows felt the need to fail 26208 jit-tests,

Backed out in
Difference from the previous patch:

+        if remote_prefix:
+            # If we are running through the device manager we need to escape the string differently.
+            expr = ('const platform="%s"; const libdir="%s"; const scriptdir="%s"'
+                    % (sys.platform, libdir, scriptdir_var))
+        else:
+            expr = ('const platform=%r; const libdir=%r; const scriptdir=%r'
+                    % (sys.platform, libdir, scriptdir_var))

rather than:

+        expr = ('const platform="%s"; const libdir="%s"; const scriptdir="%s"'
+                % (sys.platform, libdir, scriptdir_var))

Admittedly not the most elegant solution. Green try run on Windows here:

Let's be a bit more specific, so that this doesn't turn into magic later. How about:

# Platforms where subprocess immediately invokes exec do not care whether we use
# double or single quotes. On windows and when using a remote device, however, we
# have to be careful to use the quote style that is the opposite of what the exec
# wrapper uses. This uses %r to get single quotes on windows and special cases
# ADB/SUT, which require double quotes.

        fmt = 'const platform="%s"; const libdir="%s"; const scriptdir="%s"'
expr = fmt % (sys.platform, libdir, scriptdir_var))
