A test in UX consists of an element with a ux:Test attribute. The value of this attribute determines the name of the test.

<Panel ux:Test="MyTest">


Any JavaScript code that throws an Error will make the test fail.

<Panel ux:Test="MyTest">
        throw new Error("This will always fail");

Pure JavaScript tests are also possible using JavaScriptTest:

<JavaScriptTest ux:Test="MyJsTest" File="myJsTest.js" />

To run your tests, open a command-line shell and execute the following:

uno test <path-to-unoproj>

Where <path-to-unoproj> is the path to your Fuse project's .unoproj file.
