Bug: cannot use --app on windows

[eli88fine]

Hello, I'm using VueJS/Nuxt (although I'm sure this applies to other frameworks as well) and I typically use the --app command in TestCafe to launch npm run dev to start the server running in the background that I then test.

Using the TestCafe action, this works fine in the Linux environments in Github, but on Windows I get errors that I haven't been able to resolve: 'cannot find command npm', 'cannot find command nuxt'. I tried switching npm to npx since you use npx in your index.js file, but that didn't work either: 'cannot find command npx'.

Is there a way to be able to support the --app flag for this action in Windows environments?

Hello. I was able to reproduce an issue in my sample. However, I am not sure that it is the same issue. Please check the following repository: https://github.com/AlexKamaev/gh-action-16. Here are the results of running actions: https://github.com/AlexKamaev/gh-action-16/runs/1213939967?check_suite_focus=true Like in your case, it works on ubuntu-latest but does not work on windows-latest. So, the cause of the issue is unclear, and we need to research it.   Could you confirm that you have a similar issue?   As a workaround, you can remove the TestCafe action from your workflow file and replace it with the following commands:

- run: npx testcafe chrome tests --app "npm run start"

Yes, that looks like you are reproducing the same issue I had. Sorry I forgot to link to my repo: https://github.com/CuriBio/mantarray-frontend-components/

I tried the run npx command, but I can't seem to get it working. You can see in the action logs a variety of errors.

I tried: run: npx testcafe "chrome:headless:emulation:width=1920;height=930;cdpPort=9223;" ${{ matrix.e2e-tests }} --screenshots path=./tests/e2e/screenshots --app "npm run dev" --app-init-delay 35000

run: npx testcafe \"chrome:headless:emulation:width=1920;height=930;cdpPort=9223;\" ${{ matrix.e2e-tests }} --screenshots path=./tests/e2e/screenshots --app \"npm run dev\" --app-init-delay 35000

run: npx testcafe "chrome:headless:emulation:width=1920;height=930;cdpPort=9223;" ${{ matrix.e2e-tests }} --screenshots path=./tests/e2e/screenshots --app "npx nuxt dev --spa" --app-init-delay 35000

I'll be trying some other things, but just wanted to give you an update

Thank you for your cooperation. I reviewed your repository and found that you already have TestCafe in dependencies. It means that you can use the already installed TestCafe instead of the TestCafe action.

I modified my example from https://github.com/AlexKamaev/gh-action-16. Now, it works as expected. Please take a look at package.json:

"scripts": {
    "start": "npx http-server pages",
    "test": "node ./node_modules/testcafe/bin/testcafe chrome tests --app \"npm run start\" --app-init-delay 10000"
  },

Also, see yml:

steps:
  - name: Check out the repository
    uses: actions/checkout@v1
  - name: Npm install
    run: npm install
  - name: Run TestCafe
    run : npm test

So, it looks like the issue is not with TestCafe itself, but only with the TestCafe action.
