An example of an AI chatbot conversation about setting up test coverage in TypeScript projects.
How do I set up test coverage for my TypeScript project?
To set up test coverage in a TypeScript project, you can use tools like Jest or Mocha along with Istanbul for coverage reporting.
Can you guide me through the steps to configure Jest for TypeScript?
Sure! First, install Jest and the necessary TypeScript dependencies. Then, create a jest.config.js file and configure it to use ts-jest.
What should I include in the jest.config.js file?
In your jest.config.js, include the preset as 'ts-jest', and specify the test environment, like 'node' or 'jsdom', depending on your project.
How can I check the test coverage after running my tests?
After running your tests, Jest will generate a coverage report in the 'coverage' directory. You can view it in your browser.
