Adding integration tests with Flutter Driver According to the official documentation, integration tests require two steps: deploy an instrumented application to a real device or emulator. While flutter_driver provides all you need to test a simple app or component, it has major limitations when it comes to a real application: While such behaviour is appropriate for real world testing it make BDD completely unusable at development stage. Flutter works much like the React Native besides offering full support for the essential features. content_copy A "driver" process on the host machine (i.e. This is because Flutter Team arbitrarily decided to stop fixing problems in flutter_driver.
