(Feature) e2e tests for Wizard

[vbaranov]

Closes #509

Problem: we have no integrated e2e tests for Token Wizard
Solution: integrate token-wizard-test-automation as a submodule

[fvictorio]

Why is this necessary?

[vbaranov]

@dennis00010011b could you clarify why it is necessary?

[dennis00010011b]

@vbaranov @fvictorio
Xvfb is needed for performs graphical operations in virtual memory. e2e script uses Metamask extension but headless Chrome don't support extension. It is why Xvfb used

[fvictorio]

I was asking about the sleep 3 line.

[dennis00010011b]

It is recommended code from https://docs.travis-ci.com/user/gui-and-headless-browsers/
sleep 3 give xvfb some time to start

[vbaranov]

@dennis00010011b did you try other setups from recommended in the link above? if yes, do they work? just curious.

[dennis00010011b]

Not too much. I just tried to play with screen resolution but it wasn't helpfull

[vbaranov]

@fvictorio @fernandomg let's do not merge any PR until we will not add e2e tests.

@fernandomg @fvictorio is there anything stops us from merging?

@fernandomg please try to restart tests. You can see it worked with this PR. Anyway, @dennis00010011b will try to increase stability in the next releases of test-automation script.

[dennis00010011b]

@fernandomg There is should be result.log file(see path ./results/result_date_time/) Could you send it me?

[fernandomg]

Now it worked. Thanks!

Sorry, I moved to another issue and cleaned up the workspace. Now it worked. Thanks

[fvictorio]

@vbaranov I think this can be merged now.
