@alexleonard If I set APP_ENV to testing in my .env.testing file in the sample application and dump the environment in a test file it correctly says testing. Are the other environment values you specify in your .env.testing file picked up by the application?

Hmm, I wonder what's causing it to not pick it up.

Here's a screenshot showing my functional.suite.yml, .env.testing, the Cept where I dd env values, and my composer.json file, plus CLI output of composer update, codecept build, and codecept run.

It seems to wholly be picking up the standard .env instead of .env.testing.

I'll have a bit more of a dig around and see whether I can find out anything else.

Sorry about this!

@alexleonard you functional.suite.yml is wrong. The config key should be a child of modules.

D'oh. And there was I thinking I had double checked everything. Sorry dude...

You've fixed me up once again! Working straight out.
