Is this a regression?

Don't know

Description

The ng test documentation states "When a project name is not supplied, it will execute for all projects". However, this does not appear to be true. Only the tests for a single project are run.

🔬 Minimal Reproduction

1. Clone https://github.com/swseverance/my-workspace
2. npm install
3. Run ng test and observe how only the tests for the app are run. The tests for the lib are not run.

OR

1. Create a workspace
2. Create an app within the workspace
3. Create a lib within the workspace
4. Run ng test and observe how only the tests for the app are run. The tests for the lib are not run.

Anything else relevant?

I think we should clarify the docs, that this only happens when test are not run in watch mode (Which is true by default).

[TrevorKarjanis]

The newly generated repository for #21619 reproduces this as well, but our upgraded v12 application does not.

Interesting so something else might be going on

I stand to correct myself. The test command runs only the default project tests when a project is not provided and watch true by default. All tests are run when no project is provided and watch is false which we found useful for CI. Sorry for the confusion.

So what is the solution to run all tests in monorepo?

[BePo65]

According to pr #21478 the documentation should clarify that all projects are only tested, when --watch=false. Will the content of that pr also be included in the angular docs or is this a different repository?

Anyway: angular.io does not yet show the modified documentation.

In #21478 it was decided it's not a purely documentation issue.

#26850 contains reproduction instructions with Angular 17 cli.

I wonder if the fix effort is tied with web-test-runner, since @dgp1130 wrote Moving Angular CLI to Jest and Web Test Runner, would you happen to know?
