The following test is intermitent in travis: https://travis-ci.org/mozilla-b2g/gaia/jobs/26181184 1) [communications-contacts] contacts/navigation should send show-navbar to dialer when leaving view-contact-form: TypeError: Attempted to wrap undefined property postMessage as function at wrapMethod (http://communications.gaiamobile.org:8080/common/vendor/sinon/sinon.js:522:1) at spy (http://communications.gaiamobile.org:8080/common/vendor/sinon/sinon.js:1080:9) at spy (http://communications.gaiamobile.org:8080/common/vendor/sinon/sinon.js:2490:13) at (anonymous) (http://communications.gaiamobile.org:8080/contacts/test/unit/navigation_test.js:277:9) at wrapper (http://communications.gaiamobile.org:8080/common/test/mocha_generators.js:62:13) at run (http://communications.gaiamobile.org:8080/common/vendor/mocha/mocha.js:3709:7) at runTest (http://communications.gaiamobile.org:8080/common/vendor/mocha/mocha.js:4087:5) at (anonymous) (http://communications.gaiamobile.org:8080/common/vendor/mocha/mocha.js:4133:7) at next (http://communications.gaiamobile.org:8080/common/vendor/mocha/mocha.js:4013:7) at (anonymous) (http://communications.gaiamobile.org:8080/common/vendor/mocha/mocha.js:4022:7) at next (http://communications.gaiamobile.org:8080/common/vendor/mocha/mocha.js:3970:16) at (anonymous) (http://communications.gaiamobile.org:8080/common/vendor/mocha/mocha.js:3990:5) at (anonymous) (http://communications.gaiamobile.org:8080/common/vendor/mocha/mocha.js:4938:28)

Jose could you take a look? Thanks!

Note that this is in v1.4.

Travis is permared on v1.4 because of this, Francisco, can you please backout whatever did this?

Germán will be taking a look this morning. If we don't find a quick fix I would suggest we skip that test

What's the status for this?

First failing Travis build is https://travis-ci.org/mozilla-b2g/gaia/jobs/26181184 It's completely unrelated so IMO this shows that there is probably a Firefox change. Maybe we should fetch the correct Firefox version for this branch? I filed a separate bug for this: bug 1018896. But I'd like to know why this does not fail in master? Is the test different?

Taking a look to this, 1.4 shouldn't be red :(

So, same Firefox, v1.4 fails, master works. I added logs in both tests that spy on window.parent.postMessage, and... * in master, window.parent.postMessage is always null: in both tests, before and after the spying * in v1.4, window.parent.postMessage is "normal" before the first spy, then it's a sinon spy after the first spy (in the first test); then it's undefined in the second test before the second spy. I also added logs in test-agent's sinon_helper.js on v1.4, and I saw that window.parent.postMessage turns to "undefined" after restoring sinon's sandbox. I don't see what changed in https://travis-ci.org/mozilla-b2g/gaia/jobs/26181184 However, we have different sinon versions between 1.4 and master, so I'll try this now.

upgrading sinon seems to work, I'll prepare a PR.

Let's see how Travis like this before requesting a review. I _still_ don't know what changed to make this red, though.

Fixed by uplifting bug 995425 (I don't know what the main issue was, and I don't really care)
