How can I implement advanced testing in a TypeScript Express application?
You can use frameworks like Jest or Mocha for testing. Would you like to see an example of setting up Jest?
Yes, please provide an example of setting up Jest for my Express app.
First, install Jest and its TypeScript types: npm install --save-dev jest @types/jest ts-jest. Then, create a jest.config.js file.
What should I include in the jest.config.js file?
You should include the following configuration: module.exports = { preset: 'ts-jest', testEnvironment: 'node' };. This sets up Jest to work with TypeScript.
