PHP Notice: Constant ABSPATH already defined when setup using WP-CLI on VVV

[dingo-d]

I've set up the plugin test using scaffold in WP-CLI. In my plugin the plugin structure is

my-plugin/
  |
  - bin
      install-wp-tests.sh
  |
  - tests
     bootstrap.php
  ...

I've installed everyting I need with Composer.

The install script installs the test WordPress in some temporary folder on my Mac /var/folders/xj/asdq3e232ad.../T/wordpress

When I run the tests without adding the WP_Mock in my bootstrap the phpunit works fine. But when I add

// First we need to load the composer autoloader so we can use WP Mock
require_once dirname( dirname( __FILE__ ) ) . '/vendor/autoload.php';

// Now call the bootstrap method of WP Mock
\WP_Mock::bootstrap();

I get an error

For local environment I'm using VVV.

I'm unsure how is VVV affecting the unit tests. Should I remove wordpress-develop from it and it should work?

EDIT:

Deleted the wordpress-develop and when running

bash bin/install-wp-tests.sh wordpress_test root '' localhost latest

and then running phpunit I still get the same error.

WP_Mock is incompatible with the core test framework (what you get when you scaffold a plugin). #49 is currently open requesting the ability to use both in the same test suite, but the conclusion seems to be that you need separate test suites to make it work. #114 is also under discussion, which would get around the problem by at least making it easier to get a plugin set up correctly with WP_Mock instead of the WP core framework.

Oh, I see. Thanks for the explanation! :)
