In this post I want to show how you can trigger all your unit tests to get run using a keyboard shortcut in Visual Studio Code as well. I’m implementing this by setting up a task using Gulp and then making VSCode aware of the task, but flagging that task as a test task.
While you can install it globally using
npm install -g gulp, I prefer to add it to just my current project. First make sure you have a
package.json file in the root of your project… if you don’t just run
npm init and answer a few questions to get one created.
Then install Gulp as a dev dependency which means it won’t be downloaded when you deploy your app in a production sense. Do this by running
npm install gulp --save-dev. Because I’m also using mocha to run my tests I also have the gulp plugin gulp-mocha to run my tests… you can look at the
package.json in the generator-nodehttps to see what else I’m using.
Now that you have that setup, create the task by creating a
gulpfile.js in the root and adding the following code. This assumes your tests are all in a folder named test in the root of your project:
Now that you have the Gulp task setup, you can setup VSCode. Within VSCode, hit SHIFT + CMD + P, type task and pick Task: Configure Task Runner. This will create a
.settings / tasks.json file with a bunch of default code. Replace it with the following. This tells VSCode that you have Gulp tasks, specifically there’s one named run-tests and it’s a test command.
Now, when you’re in VSCode, you can press SHIFT + CMD + T or use the command Tasks: Run Test Task and it will execute your tests within the output window in VSCode that looks like so:
