I have just tested with safari, chrome --incognito and chrome:headless.
chrome --incognito fails same way, but chrome:headless is OK, safari OK

Hi @luckylooke,

I've tried to reproduce the problem, but to no avail. Test passes on my Mac. According to a report a js-error occurs on the page when typing text in the input. Please, use chrome dev-tools to try to catch this error and send us your results. It will be very useful for solving the problem.

Thanks!

I suppose some extension breaks TestCafe behavior in your Chrome. Please check whether some extensions are enabled in the incognito mode in your browser. Disable them and try to rerun the test.
Meanwhile, we are going to run tests with a clean browser profile by default since the [email protected] version (see #1792). It should resolve the problem.

[luckylooke]

@AlexanderMoskovkin I have some extensions but none of them is enabled in incognito mode.
@churkin no error in dev tools console. I was also trying to step through but it is overwhelming call stack and when I try to stop just on exceptions. There are plenty of handled exception. It is impossible to distinguish which one is the cause. :/

Hello @luckylooke, there might be something with you profile, maybe some Chrome settings. I think so because chrome:headless uses a completely empty temporary profile and it works, but chrome --incognito doesn't. Until we are in process enabling empty profiles by default, you can use --user-data-dir=$SOME_DIR flag. E.g.:

mkdir /tmp/temp-chrome-profile
testcafe 'chrome --user-data-dir=/tmp/temp-chrome-profile' test.js

[luckylooke]

@AndreyBelym your hack works.. maybe it is because I have multiple profiles in chrome? I don't know, but thanks, now I can test on chrome too ;) Should I close this? Or do you plan to fix it on your side?

[AlexanderMoskovkin]

@luckylooke, Great! Since the issue is resolved I close it in favor of #1623.
