You can't run that command directly unless you have set up tests on your host environment. You gave to use the npm wrapper instead, AFAIK.

[mukeshpanchal27]

Got it. But we should document this somewhere so others understand why it’s not working. What do you think?

[westonruter]

Yeah, agreed. That error message should explain this, and reference the npm command to use instead. It could link to the handbook with instructions for how to set up the test environment without using wp-env as well.

Hey, I was thinking of a an approach where we can define a pretest script to run before composer test like this:

"pretest": "php pretest.php",
"test":  ["@pretest", "phpunit"],

In the pretest.php script we can check if the environment is correct and print error message accordingly.

Should I go ahead with this approach or is there a better way?

[westonruter]

@AhmarZaidi that seems good to me.
