testcafe-browser-provider-android's Issues

Screenshot fails: Error: EXDEV: cross-device link not permitted, rename ...

Screenshots can not be taken if the target directory is in another filesystem than the cwd.

Was unable to take a screenshot due to an error.

Error: EXDEV: cross-device link not permitted, rename 'screen.png' -> '/home/testsystem/network/share/test/android_chrome/master/0_Start.png'

This can be resolved by switching from rename to copy&unlink

Better Error Messages: Browser not installed?

There should be better error messages.

  1. No devices listed by adb devices (exception)
  2. For each device: Chrome or Firefox not installed (info)
  3. None of the devices has Chrome or Firefox installed (exception)

This would also help debug #11

Devices connected via tcpip dont work

When connected via tcpip (https://developer.android.com/studio/command-line/adb#wireless) testcafe-browser-provider throws an exception:

This is because of the naiive assumption that the browserName always has exactly two colons (:) ${model}:${deviceId}:${browser.name}. But this is not true for devices that are connected via tcpip. They have four colons: ${model}:${deviceHostname}:${port}:${browser.name}

Start Chrome in incognito mode

Although the current solution makes sure that each run starts with a clean browser, it is still undesireble to reset the complete browser. Some users might test on devices that are not exclusively used for testing. The current approach deletes all user data.
