powerbi-visuals-utils-testutils
npm install powerbi-visuals-utils-testutils> TestUtils is a set of mocks and fakes in order to simplify unit testing for Power BI custom visuals
From version 2.3.0 testDom function returns HTMLElement instead of JQuery object. If you are using JQuery in tests, wrap the testDom calls with $(...) for compatibility:
``typescript`
// 2.2.1 and below
let element: JQuery = testDom("100", "100");
// 2.3.0 and above
let element: JQuery = $(testDom("100", "100"));
The motivation is not to force JQuery usage. It might be not necessary in tests. In lots of cases element.get(0) is the next operation after receiving an element with testDom`. Now JQuery is not required to use powerbi-visuals-utils-testutils, so you can drop this dependency. If you keep it, you can easily migrate your code to 2.3.* version using the example above.
