Jasmine provides the testing syntax, while Karma runs your tests in real browsers and reports the results. This guide walks you through setting up Karma with Jasmine in your project.</p> <h4>Step 1: Install Jasmine</h4> <p>First, install Jasmine as a development dependency:</p> <pre>npm install jasmine jasmine-core --save-dev</pre> <pre>npx jasmine init</pre> <pre>npm test</pre> <p>This sets up Jasmine in your project and adds a basic test structure.</p> <h4>Step 2: Install and Configure Karma</h4> <p>Install Karma and the necessary plugins:</p> <pre>npm install karma karma-jasmine karma-chrome-launcher karma-jasmine-html-reporter karma-typescript --save-dev</pre> <p>Install the Karma CLI globally:</p> <pre>npm install -g karma-cli</pre> <p>Generate a fresh Karma configuration file:</p> <pre>karma init</pre> <p>During the setup, select Jasmine as the testing framework and Chrome as the browser. Modify the generated karma.conf.js to suit TypeScript projects and your file structure.</p> <p><a href="https://karma-runner.github.io/1.0/config/configuration-file.html">Configuration File</a></p> <p>When your using TypeScript you will need to configure Karma accordingly</p> <p><a href="https://karma-runner.github.io/6.4/config/configuration-file.html#customized-typescr...
