Would be nice to get this PR

In ember-basic-dropdown i have isTesting() in use, which isn't working right now without adding a workaround in test-helpers start() function

@NullVoxPopuli the fix of this branch works only partially...

I have an issue found out with ember-power-select and ember-basic-dropdown.
The ember-basic-dropdown addon has two isTesting() points (see here, this is the more critical point, when it stays false while testing).

When the ember-power-select is using the workaround from this branch, isTesting() is inside the ember-power-select addon true in test, but in ember-basic-dropdown code parts it's always false, which is not expected.

If you run this in ember app test (like ember-power-select docs), isTesting() is true, which is expected.

If you want test this issue, you can do this with following steps.

1. Download ember-power-select (https://github.com/cibernox/ember-power-select)
2. Run pnpm i
3. Insert a console.log(isTesting()); in node_modules/ember-basic-dropdown/dist/components/basic-dropdown.js
4. Run pnpm test on root or pnpm start with http://localhost:4200/tests

The isTesting() is always false and so all tests will normally fail. I have only added a workaround in eps, by setting destination (https://github.com/cibernox/ember-power-select/blob/master/tests/test-helper.ts#L51-L54, normaly this should not be needed)

Today i have again debugged the issue from power select / basic dropdown.

I have moved macro to peerDep in ember-basic-dropdown, but this hasn't solved the issue...

The only way to get inside basic dropdown isTesting() to true is to use import { isTesting } from '@embroider/macros/src/addon/runtime'; instead import { isTesting } from '@embroider/macros'; in basic dropdown addon.

Inside tests/test-helper.ts there is possible to take import { getGlobalConfig } from '@embroider/macros'; instead import { getGlobalConfig } from '@embroider/macros/src/addon/runtime'; (helps to reduce disable ts errors).

Maybe the best and clean way will be, that addon's which are using isTesting() (like ember-basic-dropdown in my case) should provide an option to set isTesting; true... something like setConfig({ isTesting: true }) (no hidden/magic embroider logic inside addon)

what happens if you remove @embroider/macros entirely from the library? I wonder if you're having a bad peerdep / dep graph situation?

tried locally with an patch, removing in ember-basic-dropdown the @embroider/macros... but it doesn't make a difference... same issue

with a patch

what happens when you cd into ember-basic-dorpdown and then run npx y-which @embroider/macros?

npx y-which @embroider/macros

npx y-which @embroider/macros

  Node resolves @embroider/macros 
       to   ~/projects/github-master/ember-power-select/node_modules/.pnpm/@[email protected]_@[email protected]/node_modules/@embroider/macros/src/index.js
       which is @ 1.19.6

     from   ember-basic-dropdown @ 8.11.0 
       at   ~/projects/github-master/ember-power-select/node_modules/.pnpm/ember-basic-dropdown@https+++codeload.github.com+cibernox+ember-basic-dropdown+tar.gz+f_cefe780ebb12e25c8fa2a0c6321373d8/node_modules/ember-basic-dropdown

I would expect macros to not return a result, if you're testing in a full app, fwiw -- this leads me to believe a potential peer issue - maybe injected deps are needed
