A class that provides assertion methods to be applied to a selection of rendered output elements.

class OutputAssertion

Notes

• An instance of this class is returned by the TestCase.expectOutputAsync(), TestRenderer.expectOutput(), and TestRenderer.expectOutputAsync() methods. Use these methods to create new assertions based on the currently rendered (test) output.

Constructor

• constructor(elements, select?)Creates a new assertion based on given elements, optionally filtered using given selection criteria.

Instance Members

• elements readonlyThe elements to be asserted.
• containing(select)Returns a new OutputAssertion for any elements that are contained by the current set of elements (i.e. container content), directly or indirectly, which match the given selection filter.
• getSingle()Returns the currently matched output element, if there’s only one.
• getSingleView(type)Returns the view object that rendered the currently matched output element, if there’s only one.
• toBeRendered(description?)Asserts that any output elements were matched at all.
• toBeEmpty(description?)Asserts that no elements were matched at all.
