Currently, I am developing a project in TypeScript and for unit-tests, I am utilizing QUnit and sinonjs. One of the functions within my code dynamically renders UI elements. I need to retrieve the width of these dynamic elements in order to perform additional computations. To ensure the correct calculation of the width, I have included a setTimeout function. Here's a snippet of the code:
public function1(): void {
this._createShowMoreUI();
setTimeout(delegate(this, this.function2), 0);
}
private function2(): void {
// use this._element.width();
}
Overall, everything seems to be working fine except for one issue - when function1 is called from a unit-test, function2 is never executed. Upon researching online, I found suggestions on how to mock out setTimeout or common mistakes related to its usage (such as setTimeout(function2(), 0), which did not address my specific problem.
