Espresso Testing Framework - Accessibility

Accessibility feature is one of the key features for any application. The application developed by a vendor should support minimum accessibility guideline set by the android SDK to be a successful and useful application. Following the accessibility standard is very important and it is not an easy task. Android SDK provides great support by providing properly designed views to create accessible user interfaces.

Similarly, Espresso testing framework does a great favour for both developer and end user by transparently supporting the accessibility testing features into the core-testing engine.

In Espresso, a developer can enable and configure accessibility testing through the AccessibilityChecks class. The sample code is as follows,

AccessibilityChecks.enable();

By default, the accessibility checks run when you perform any view action. The check includes the view on which the action is performed as well as all descendant views. You can check the entire view hierarchy of a screen using the following code −

AccessibilityChecks.enable().setRunChecksFromRootView(true);
