Why your mobile XPath breaks: a practical ranking of locator strategies for Android, iOS and Flutter
A lot of what gets filed as "flaky mobile test" is a locator that was never stable in the first place. The test passed for three weeks, a developer wrapped a view in a FrameLayout , and an absolute XPath that encoded the entire hierarchy fell over. Nobody touched the test. It still broke. This is the order I pick locators in, why, and what each one looks like when it fails. Android and iOS first,…
Flaky mobile tests often result from unstable locators. A seemingly stable XPath can break unexpectedly, even if no changes are made to the test itself. This article outlines the order in which to prioritize locators, along with their strengths and weaknesses for Android, iOS, and Flutter applications. The key principle is to use attributes that developers define purposefully, rather than relying on the render tree.
