karma tests fail

[hackergrrl]

Current master fails karma tests consistently for me.

> karma start karma.conf.js

That output looks like it didn't even try to run the browser tests, I looked at the travis output and the tests were timing out.

npm test executes test:browser, making local tests fail for me. :(

[nginnever]

Sorry i didn't see that, edited my comment above.

npm run test:browser works for me

Are there any errors thrown or does it simply not test like above?

Travis seems to be failing on time out on your PR
https://github.com/nginnever/js-ipfs-data-importing/blob/master/tests/buffer-test.js#L26

Looks like you are getting disconnected from chrome?

[hackergrrl]

No errors output other than what I posted above.

I don't think my PR is related, since Karma tests fail even on the 0.3.0 release commit when I run them. I haven't had this problem on any other repos that have Karma tests.

Fails on Firefox 45 too:

Upgraded to Chromium 49 -- no change in the error experienced.

[nginnever]

Can you try running the tests on js-ipfs-merkle-dag module? They are structured in exactly the same way but those tests don't have a 1.2Mb file to be buffered.

[hackergrrl]

Yes, the js-ipfs-merkle-dag tests have work fine for me.

Travis is failing on 463454d yet it is not part of the history anymore. @noffle ?

Tests run fine for me on Chrome, but not on Firefox on travis(anymore) #11 . They were fine yesterday https://travis-ci.org/ipfs/js-ipfs-data-importing/builds/117366855 . @nginnever thoughts?

[daviddias]

greeeen :) #12

[hackergrrl]

Fixed in #8. The home-made chunker used was allocating ~O(100n) bytes, causing the 1.2mb file to crash Chrome and Firefox. I switched us to block-stream2, which is O(n) and supports zero-padding too.
