运行ng test时在项目中找不到配置

Question

I have just upgraded to Angular 6 but now our Jenkins build is failing.

It is running this command:

ng test -c karma.conf.cli.js

But the error is:

Configuration 'karma.conf.cli.js' could not be found in project 'projectname'

However, the file in question exists in the root of the project. This command was running fine on Angular 5. Any ideas? Thanks

FYI I can reproduce the error by running the same command on the build server. We have also just upgraded Node.js to v8.11.2 (latest LTS)

Answer 1

In the version 6 of Angular Cli the options for the commands has changed, instead use -c , you should use --karma-config or --configuration . You can see all options here .

Answer 2

I tried many and the one worked for me is as below. In your angular.json file add configuration section under test below.

    "test": {
      "builder": "@angular-devkit/build-angular:karma",
      "options": {
         ....
      },
      "configurations": {  // this will hold a different configuration
        "jenkins": {
          "karmaConfig": "./karma.conf.ci.js"
        }
      }
    },

And then while running the test use this configuration with --configuration jenkins options. So the final command will be

ng test --configuration jenkins

It will pick karma.conf.ci.js as configuration file as it set in the configuration section in angular cli configuration file and run unit test using that configuration file.

I had the same issue in Jenkins after Angular 6 and I solved by replacing:

ng test --single-run --browsers ChromeHeadless -cc 

with:

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