Test authors use a testing framework to write end-to-end tests and automate browsers. Edge WebDriver is then responsible for communicating that command to the browser. Test authors write tests that use WebDriver commands that Microsoft Edge WebDriver receives. Microsoft's implementation of the WebDriver protocol specifically for Microsoft Edge. This protocol allows out-of-process programs to remotely instruct the behavior of web browsers. The functional relationship between these components is as follows: TechnologyĪ W3C standard for a platform- and language-neutral wire protocol. To automate Microsoft Edge with WebDriver to simulate user interaction, you need three components: Relationship between WebDriver and other software WebDriver runs multiple sessions of Microsoft Edge on a specific machine. WebDriver manages multiple windows, tabs, and webpages in a single test session. WebDriver simulates user events or OS-level events more accurately than JavaScript unit tests. WebDriver accesses functionality and information that's not available to JavaScript running in browsers.

Tests that use WebDriver have some advantages over JavaScript unit tests that run in the browser: WebDriver allows you to automate Microsoft Edge by simulating user interaction.
