For EarlGrey 2, please go to earlgrey2 branch.

EarlGrey is a native iOS UI automation test framework that enables you to write clear, concise tests.

With the EarlGrey framework, you have access to enhanced synchronization features. EarlGrey automatically synchronizes with the UI, network requests, and various queues; but still allows you to manually implement customized timings, if needed.

EarlGrey’s synchronization features help to ensure that the UI is in a steady state before actions are performed. This greatly increases test stability and makes tests highly repeatable.

EarlGrey works in conjunction with the XCTest framework and integrates with Xcode’s Test Navigator so you can run tests directly from Xcode or the command line (using xcodebuild).

Getting Started

The EarlGrey documentation for users is located in the EarlGrey/docs folder. To get started, review the EarlGrey features, check for backward compatibility, and then install/run EarlGrey with your test target. After everything is configured, take a look at the EarlGrey API and start writing your own tests.

Getting Help

If you need help, several resources are available. First check the FAQ. If you have more questions after reading the FAQ, see Known Issues. You can bring more specific issues to our attention by asking them on using the #earlgrey tag. You can also start new discussions with us on our Google group or request to join our slack channel.


To prioritize and improve EarlGrey, the framework collects usage data and uploads it to Google Analytics. More specifically, the framework collects the MD5 hash of Bundle ID, Test Class Names and Test Method Names. This information allows us to measure the volume of usage. For more detailed information about our analytics collection, please peruse the GREYAnalytics.m file which contains the implementation details. If they wish, users can choose to opt out by disabling the Analytics config setting in their test’s - (void)setUp method:

In Objective-C:

// Disable analytics.
[[GREYConfiguration sharedInstance] setValue:@(NO) forConfigKey:kGREYConfigKeyAnalyticsEnabled];

In Swift:

// Disable analytics.
GREYConfiguration.sharedInstance().setValue(false, forConfigKey: kGREYConfigKeyAnalyticsEnabled)
