Tips on using Visual Studio Code to troubleshoot Angular 4 unit tests

I am working on an Angular 4 project with Material design in Visual Studio Code. The setup is done using angular/cli.

Currently, I have been writing unit tests using Karma and Jasmine. However, when trying to debug the tests by setting breakpoints, it does not give any results.

I have searched online for solutions on configuring Karma and VSC, but none of them seem to work. It might be a version-specific issue.

Based on my project setup, can anyone provide some assistance?


// Dependency versions

EDIT

If I share my configuration files, maybe someone can pinpoint any potential problems.

// tsconfig.json

{
  "compileOnSave": false,
  // Compiler options...
}

// tsconfig.spec.json

{
  // Configurations...
}

// karma.config.js

module.exports = function (config) {
  // Configuration settings...
};

// launch.json

{
    "version": "0.2.0",
    "configurations": [
        // Various configurations...
    ]
}

Answer №1

I successfully resolved the issue by setting up a fresh Angular project using the latest angular-cli. After ensuring it was running smoothly, I transferred the configuration files over to my existing project.
