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

I am running the following command to unit test and generate code code coverage report.

ng test --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 files/directory let say src/app/quote/services/generated. How to do that?

    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": {
  "options": {
    "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/**/*"
    ]
  },
  ...
}
