#asyncUtilTimeout option

Default timeout, in ms, for async helper functions (waitFor, waitForElementToBeRemoved) and findBy* queries. Defaults to 1000 ms.

#defaultIncludeHiddenElements option

Default value for includeHiddenElements query option for all queries. The default value is false, so all queries won't match elements hidden from accessibility. This is because users of the app wouldn't be able to see such elements.

This option is also available as defaultHidden alias for compatibility with React Testing Library.

#defaultDebugOptions option

Default debug options used when calling debug(). These default options are overridden by the ones you specify directly when calling debug().

#concurrentRoot option

Set to false to disable concurrent rendering. Otherwise, render defaults to using concurrent rendering used in the React Native New Architecture.

#resetToDefaults()

function resetToDefaults() {}

#Environment variables

#RNTL_SKIP_AUTO_CLEANUP

Set to true to disable automatic cleanup() after each test. This works the same as importing react-native-testing-library/dont-cleanup-after-each or using react-native-testing-library/pure.

$ RNTL_SKIP_AUTO_CLEANUP=true jest

#RNTL_SKIP_AUTO_DETECT_FAKE_TIMERS

Set to true to disable auto-detection of fake timers. This might be useful in rare cases when you want to use non-Jest fake timers. See issue #886 for more details.

$ RNTL_SKIP_AUTO_DETECT_FAKE_TIMERS=true jest
