The agent object is your primary tool for interacting with the browser within a Magnitude test. It’s an instance of the TestCaseAgent class. TestCaseAgent extends BrowserAgent and includes all of its methods, such as act(), nav(), and extract(). In addition to the inherited methods, TestCaseAgent provides the following methods for making assertions:

​
agent.check(description)

Verifies that a certain condition holds true on the web page based on a natural language description. The AI evaluates the description against the current page state (DOM, visibility, text content).
