Continous testing achieved from in the VS Code terminal using dotnet watch.I was playing around with a new project the other day and went looking for extensions to show my code coverage, after a little setup I had something running, I was really surprised at how well it all hung together. If you’ve not already given it a go I recommend you do (Did I mention LiveShare?). VS Code is so much more than a text editor, out of the box you get a full-fledged debugger, ability to attach to remote machines, Live Share for pair programming and an extension for almost everything. Visual Studio is excellent, but on personal projects where I’m normally playing around on a low powered laptop and don’t need 99% of the features in Visual Studio, VS Code is my goto. In your tsconfig.json file change rootDir parameter to. With this change you also need to change a couple of parameters in your tsconfig.json file and package.json file. To fix this, move test folder out of src folder so they will be on the same level. The problem with tests code coverage arise from a simple fact that coverage is measured for src folder and tests code is there as well. That doesn’t seem right, so let’s fix it by some structural changes. It looks really nice, but you may noticed one small problem here that tests code was covered as well.

You now can open index.html file there to see HTML-based report. Yay! All the information related to code coverage was saved to coverage folder in the root of your extension. Reports written to /Users/rpeshkov/Developer/vscode-extensions/vscode-testcov/coverage Create file coverconfig.json in the root of your project with the following content: Originally this code is taken from here, but I’ve made some changes to be compatible with strict mode.Īlso, you need to provide configuration for the Istanbul.
