Browser in configuration file are parsed even if browsers are given on the command line

[piefel]

Applies to TestCafé 1.16.1

What is your Test Scenario?

I have a .testcaferc.json file such as:

{
    "browsers": ["ie", "firefox"]
}

Also, I do have Firefox installed but not Internet Explorer.

What is the Current behaviour?

I call npx testcafe edge tests/ --skip-js-errors

Now I get: ERROR Cannot find the browser. "ie" is neither a known browser alias, nor a path to an executable file.

What is the Expected behaviour?

Since the browser edge is given on the command line, the browsers from the config file should be ignored.

This is a change from previous behaviour. At least for 1.10.1, the config file browsers list was ignored. It took me ages to pinpoint the problem when our CI broke: We had a .testcaferc.json checked in for local development, but CI tried to use Browserstack instead; now the build broken just saying that chrome was not available.

Thank you for reporting this to us. I was able to reproduce the issue.

I just noticed that under certain circumstances, the browsers list in the configuration file is checked (including a bad exception if the browser is not found), but then ignored:

$ npm run test:browserstack:ie11

> ui-tests@1.0.0 test:browserstack:ie11 /…/ui-tests
> export $(cat .browserstack-config.properties | xargs) && testcafe 'browserstack:ie@11.0:Windows 10' tests/ --reporter teamcity

The "browsers" option from the configuration file will be ignored.

Running testcafe through npx directly, or having it in package.json without the export bit, will still result in the browser from the command line being ignored completely.

The issue is not reproduced with testcafe@1.18.0.

Hello @miherlosev,
I have the same problem than @piefel.
I have a .testcaferc.json such as :
{ "browsers": [ "chrome", "firefox", "edge" ], "src": "tests/e2e/**/*.ts" }

When I launch my tests with testcafe v 1.18.1 from my gitlab pipeline I have the following error "ERROR Cannot find the browser. "edge" is neither a known browser alias, nor a path to an executable file." The browser name provided by the command is ignored.

When I launch the same tests with an older version of testcafe, v 1.14.2, everything works fine

@miherlosev, cloud you do the test with an other OS than Windows, please?

Hi @dboujot,

Thank you for pointing this out. I was able to reproduce it on a Mac device. Please stay tuned for further updates.

Hi @AlexanderMoiseev,
I would have liked to know if this bug could soon be taken into account for correction?

Thanks for your feedback

Any personal estimate may be misleading, so we cannot currently tell it at the moment. Once we get any results, we will post them in this thread.

Release v1.19.0-alpha.1 addresses this.
