ng test failing

[dbnex14]

Following this article is not easy by itself but I did and once I issue ng test, I get

mymac > ~/devwork/UiSpringAngular/client > master > ng test

Node packages may not be installed. Try installing with 'npm install'.
Could not find the '@angular-devkit/build-angular:karma' builder's node package.

I am not surprised it is failing since in step before that, the instructions are saying to delete node_modules folder from client app generated within the Spring Boot project

I already had Angular CLI installed on my mac, so I skipped that part in the instructions.

My project structure now looks like

UIApp
  |-client   // deleted its node_modules, favicon.ico, .gitignore as per instructions
       |+src
       |-angular.json  // modified its output path to "outputPath": "target/classes/static", as per instructions
       |-...
  |+node
  |-src
      |+main
      |+test
  |-pom.xml
