EarlGrey is a Google iOS UI automation test framework that allows testing the view hierarchy of an iOS app similar to Appium but is faster. Some key points about EarlGrey include: - It was released in 2016 as an alternative to Appium for iOS UI testing. - Common testing issues with EarlGrey include elements not being visible when expected or timeouts occurring when waiting for actions to perform. - When tests fail on a staging server, it can sometimes be due to flaky APIs rather than issues with the tests themselves. Tools exist to help detect and filter out flaky tests caused by external dependencies like APIs.
