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
to run my tests… you can look at the
package.json in the
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 +
, 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:
