How can I exclude all *services.ts for `ng test --code-coverage`?

Question

Under my Angular 6 I am running the following command to unit test and generate code code coverage report:

ng test --browsers=Chrome --watch=false --code-coverage

It is working fine and writing code coverage report in coverage folder.

In this I got all files and directory coverage report:

But I want to exclude specific type of files let say :

all files which have the service prefix: *.service.ts

i ve told to do that in angular.json :

 "test": {
          "builder": "@angular-devkit/build-angular:karma",
          "options": {
            "main": "src/test.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "src/tsconfig.spec.json",
            "karmaConfig": "./karma.conf.js",
            "codeCoverageExclude": ["src/*.service.ts"],

But that didn't work

Suggestions ?

In your Test.ts file you have to write this as below:

const context = require.context('', true, /\.component.spec\.ts$/);
context.keys().map(context);
