Hi Alex, i found your article quite helpful and was hoping you can guide me in obtaining coverage…

Hi Rohit! In this article, Istanbul is the primary tool used to capture test coverage and this works only with front-end and backend JS, it won’t work with Java. You can get test coverage of node.js with istanbul cover index.js but I have never heard of unit tests being written in a different language. Maybe you are writing End-to-End tests with Java? If you launch a Node.js child process with TestNg, then you can capture coverage of the Node.js process with Istanbul. Again, I don’t see how you can unit test language X using language Y. But you can definitely do end-to-end tests of language X using language Y. For example, I was considering writing our Selenium End-to-End tests using a language other than Node.js.

By clapping more or less, you can signal to us which stories really stand out.
