We have talked and written about Relish, here Relish – Living documentation instead in this article we analyze together Spoon, a distributing instrumentation tests to all your Androids.
Android’s ever-expanding ecosystem of devices creates a unique challenge to testing applications. Spoon aims to simplify this task by distributing instrumentation test execution and displaying the results in a meaningful way.
Using the application APK and instrumentation APK, Spoon runs the tests on multiple devices simultaneously. Once all tests have completed, a static HTML summary is generated with detailed information about each device and test. With the high-level output you can immediately see whether or not a test failure is specific to a single device or all devices. This view is designed to be displayed on a dedicated monitor or TV. Spoon will run on all targets which are visible to adb devices. Plug in multiple different phones and tablets, start different configurations of emulators, or use some combination of both!
In addition to simply running instrumentation tests, Spoon has the ability to snap screenshots at key points during your tests which are then included in the output. This allows for visual inspection of test executions across different devices. Taking screenshots requires that you include the spoon-client JAR in your instrumentation app.
