angular cli exclude files/directory for `ng test --code-coverage`

With the latest CLI, inside 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/testing/**/*"],

Updated September 2019

With Angular CLI 6, angular-cli.json has been renamed to angular.json which contains the configuration. In angular.json, codeCoverage expects a boolean value, which sets whether code-coverage should be done with every test run or not. To exclude files from code coverage, there is a property codeCoverageExclude which accepts an array of files to be excluded from code coverage.

angular.json

"test": {  "codeCoverageExclude": ["src/assets/vendor/**"],,  ...}

Updated answer

rc.0 has been released. You should be able to add the code snippet below to ignore files.

Original answer

Currently, you aren't able to do so in beta.32.3. A change is coming to allow this to happen. In the next release (probably rc.0), you will be able to do the following:

.angular-cli.json

"test": {  "codeCoverage": {    "exclude": [      "src/app/quote/services/generated/**/*"    ]  },  ...}
