Project Description

Karma is a test runner for JavaScript that is designed to be simple and easy to use. It is often used in conjunction with other JavaScript testing frameworks, such as Jasmine or Mocha, to provide a convenient way to run and manage tests.

It is commonly used in development environments to continuously run tests as changes are made to the codebase. This allows developers to quickly identify and fix problems as they arise, and ensure that the code remains stable and reliable over time.

Karma-runner is a command-line interface (CLI) for running Karma. It provides a number of options for controlling the behavior of Karma, such as specifying the configuration file to use, the files to include or exclude, and the browsers to use for testing.

Troubleshooting Karma-runner Karma with the Lightrun Developer Observability Platform

Getting a sense of what’s actually happening inside a live application is a frustrating experience, one that relies mostly on querying and observing whatever logs were written during development.
Lightrun is a Developer Observability Platform, allowing developers to add telemetry to live applications in real-time, on-demand, and right from the IDE.

  • Instantly add logs to, set metrics in, and take snapshots of live applications
  • Insights delivered straight to your IDE or CLI
  • Works where you do: dev, QA, staging, CI/CD, and production

The following issues are the most popular issues regarding this project:

ChromeHeadless can’t run as root with –no-sandbox anymore

We have found a viable solution to the issue through creative problem-solving – an efficient workaround.

    browsers: ['ChromeHeadlessNoSandbox'],
    customLaunchers: {
      ChromeHeadlessNoSandbox: {
        base: 'ChromeHeadless',
        flags: ['--no-sandbox']
      }
    },

Headless Chrome times out without executing any tests

To ensure a successful installation of npm packages, running the command ‘npm install && npm rebuild && npm test’ along with adding –no-sandbox to the flag list will prove effective; This method has worked for many users.
