Webstorm debug jest7/14/2023 ![]() I've made a short GIF to show you an example of how fast vitest is and how good it integrates into your dev workflow with the UI.Īs you can see in the GIF, vitest immediately rebuilds the changed code and runs the tests on it within just a few seconds. You can either hit the run button in WebStorm to simply open Vitest UI and get Insights from it while coding, or hit the debug button as always to debug your code and tests.Īdd the watch flag to make sure your UI will not close after one run. When using WebStorm, this is my WebStorm config to run Vitest UI.Īfter executing the command, the UI will open in your browser. (like issues with the node canvas package) but hey it is still in beta. ![]() I added threads false since by now there are some issues when they are on. If not, you can download the project using the download button on the top right of the navigator tab. Just run the above command and the UI should start. If you want to try it out first, you can also check it out on the official Stackblitz. To run the vitest UI, you first need to run npm i -save-devīy running, npx vitest watch -ui -threads false you can open the vitest UI. Since Vitest is currently in Beta, there is currently no out of the Box support for these IDE tools as we know it from jest or mocha.īut Vitest has build a UI to provide such an overview. So Normally an IDE has tools in place to summarize your test results for you and provide an overview on why your tests failed. When you want to dig deeper into the problem, an CLI is in my opinion always a bit harder to read due to the limitations in Size and Formatting it naturally has.Īnother disadvantage is that you need to scroll to the interesting parts after every test execution. When testing the CLI, for me, is just a good point to get an overview if all tests were running fine or if there were a Problem. Now let's get into the topic for this Article. So go ahead and try it out! Why should I Use Vitest UI?Įnough introduction about Vitest. Long Intro Short, Vitest is the 2022 testing tool the Frontend Community deserves. Vitest shares a lot of concepts with jest, which also makes the change superfast. It lets me freeze when thinking back to the dark days when I tried to set up Jest for TypeScript the first time. Vite immediately builds this changes, and all tests affected by those changes are executed in less than a minute.įor me, coming from jest, Vitests performance and simple configuration is a massive win and make TDD a lot more fun. Vitest recognizes when changes were done. ![]() What made Vitest the testing tool of choice for my applications is the super Fast HMR. Which means that your tests run in the same Environment as your application does, which make a lot more sense to me. This includes incredible features like sharing the same config () with your SUT. It is strongly focusing on providing the best possible developer experience. So instead of setting up three tools, you just need a single tool to test your application. ![]() like Babel and bundles test dependencies like webpack. Which means it is a test runner like jest, trantranspiles TypeScript, ESM etc. It combines three things that could cause problems into one. Vitest is a superfast unit-testing framework powered by Vite. It is developed by Evan You, the creator of Vue.js Anthony Fu, vite and vitest core team member patak and 533 more amazing developers. Vite has the power to immediately start up and do HMR in no time, even for large scale applications. Vite is a new frontend build tool with an insane performance. When you are reading this, you probably have already heard of Vite (french for Quick). ![]()
