Picked a sample React app on StackBlitz. How does one run unit tests?
I see many people creating an app with tests, what's the purpose if those cannot be executed?
I guess you'd need a node.js project setup in order to run those?
From Available environments documentation:
There are two kinds of environments that run projects in StackBlitz:
EngineBlockandWebContainers. Each project in StackBlitz is tied to one or the other.
From Can I run unit tests in StackBlitz? documentation:
It is also possible to run Angular unit tests inside WebContainer-based projects, but not Engineblock-based projects.
Your project uses the EngineBlock environment, you need to use the WebContainers environment.
You can see this example, please note there is a .stackblitzrc configuration file to specify the start command. The npm run test script will be run after installing the dependencies.
{
"installDependencies": true,
"startCommand": "npm run test"
}
