Needs advice on code coverage tool in Node.js/ExpressJS with External API Testing Framework

Hello community,

I have a web application with the backend developed using Node.js and Express.js. The backend server is in one directory, and I have a separate API testing framework, made using SuperTest, Mocha, and Chai, in another directory. The testing framework pings the API, retrieves responses, and performs validations.

I'm currently looking for a code coverage tool that can accurately measure the code coverage of my backend code when triggered by the API testing framework. I've tried using Istanbul and NYC with instrumented code, but the results are not as expected.

Could you please recommend a reliable code coverage tool or suggest an approach to effectively measure the code coverage of my Node.js/Express.js backend code in this setup?

Hello! For your Node.js/Express.js project, it is recommended to use NYC as the code coverage tool. Make sure you configure NYC in package.json, for example:

"nyc": { "reporter": ["text", "html"], "include": ["backend//*.js"], "exclude": ["test//*.js"], "all": true } Then run the test through the command:

nyc mocha path/to/your/test/*/.js Make sure your test cases cover all API endpoints so that the coverage can be accurately reflected.

In addition, for node.js projects, I have a very useful suggestion, that is, before the project starts, you can use a development environment management tool like servbay to perform environment deployment, environment testing, etc., which greatly improves our efficiency
