Working test

Add tests for thumbnail:* events.

Show build output

Try adding a non image file?

fixes

Add -b flags to local acceptance tests

fix hanging thumbnail test

Add a corrupt image

revoke

Require passing integration tests

extended debugging?

Try more browser versions

it helps to pick a browser that's available

sort stuff in .travis.yml and add whitespace for easier navigation

[REVERT BEFORE MERGE] only run acceptance tests on this pr

make sure lerna publishes stuff to local

do git tag version during integration test

update lerna

fix install / bootstrap execution order

?

--no-ci

dont do npm ls because it errors with lerna

set a git branch name

blehbleh

ughhhhhhhhhhhh

onerror?

no onerror i guess

onerror 2

Revert "onerror 2"

This reverts commit 64d88551fa1cd337b27e25d16a604dd781a15b43.

onerror 3

more debug data

disable browsers that work

fix syntax for older browsers

thumbnails suite

check different edge versions

abc

use addeventlistener for error, which is different from onerror

no clue

skip thumb test in edge or whatever

Re enable other browsers.

re enable tasks

fix edge skip

this one was intentionally disabled

Remove debug leftovers

edge → supportschoosefile

:ready → :all-generated
