How do I generate Json Report with CucumberAndroidJUnitRunner?

[SchlauFuchs]

Hi!

I am trying to create a JSON test report with CucumberAndroidJUnitRunner - but tests fail when I add the plugin to my runner - the tests fail. I tried different paths (like "json:build/outputs/test-results/BddTests.json" for example) and no path at all, like "json:cucumber.json" for example.

The error is always:

io.cucumber.android.CucumberJUnitRunnerBuilder > initializationError[Pixel_9a(AVD) - 16] FAILED 
	java.lang.IllegalArgumentException: Couldn't create a file output stream for [...] .
	Make sure the the file isn't a directory.

Any advise?

From memory (2017), you need to enable writing to external storage.
