The Statements category contains the following test actions.
Define Element Selector
The Define Element Selector action allows you to create an element selector that identifies a webpage element. You can define an element selector once and use it in the subsequent test actions. This makes your tests easier to read and maintain.
See Reuse Selectors for more information.
You can also access element selectors declared with this action from custom scripts. Element selectors are represented by Selector objects in script code.
The Define Function action allows you to create a function that returns data from the tested webpage. You can then verify this data in assertions.
This type of function cannot return non-serializable objects (DOM elements, window, etc.). Use element selectors instead.
To create a function:
Specify the function's name in the Name field.
Function names must be unique in a test. You also cannot use the following reserved words: t, fixture, test, Selector, ClientFunction, RequestLogger, RequestMock, and RequestHook.
Write the code. Use the return statement to return the desired data.
You can also access functions declared with this action from custom scripts. Functions are represented by ClientFunction objects in script code.
The following image demonstrates how to define a function that returns the URL of the currently open page.
Then you can verify if the returned URL matches the expected URL using the Deep Equal assertion.
You cannot use generators or async/await syntax within functions. To run asynchronous code, use a Promise within a function. The function is complete only when this Promise resolves.
You cannot use element selectors within functions.
