How can I execute ng test for all components of sub modul of Angular app

Issue

I have my angular app, declared like this:

app.module.ts

export class AppModule {}

for which I can run tests with ng test MyApp

Within this app, I have multiple modules, declared like this:

my-one.module.ts / my-other.module.ts

export class MyOneModule {}

export class MyOtherModule {}

These are imported in AppModule.

How can I do something like ng test MyOneModule / ng test MyOtherModule, with which I'd like to run just the tests of all components in that very "sub module" instead of all tests in the app?

I couldn't find information in the official docu or here in StackOverflow. Is it possible at all?

Solution

I ended up using this workaround:

In test.ts I change the path:

const context: any = require.context('./', true, /\.spec\.ts$/);

to

const context: any = require.context('./app/modules/my-one-module', true, /\.spec\.ts$/);

or

const context: any = require.context('./app/modules/my-other-module', true, /\.spec\.ts$/);

This causes ng test to just execute the tests in the defined directory (and its sub directories).

Not ideal, as I don't like to make changes to checked-in files, that are not meant to be committed, but it does the job.
