Testing is a key activity in any software development effort. Manual testing (e.g., with QA personnel) allows a lot of flexibility, but testing old features repeatedly can be mind-numbing and cause testers to miss things. Manual testing also usually involves a full end-to-end system, so it can be difficult to test edge cases and error conditions because they can be difficult or impossible to recreate on-demand in the real system.

You’ve gone through all of the steps to make an awesome app that users will love and come back to time and again. Today is the day you release it to the Google Play Store. “Good luck little app,” you think as the developer hits publish. “Make me proud; you’ve only got about 1,400,000 other Android apps to compete with!” Getting your app discovered through the store is a growing concern for developers as the number of Android applications grows by the hundreds of thousands every year. Data collected from over the past few years* has shown that users primarily discover new applications through searching the app stores. While there are several other ways for your application to be found (word of mouth was second), app store visibility should not be overlooked. A user must know an application exists before they can download it. So, wat do?

When the first generation of the Moto X was first released, it proved you could have a fast, solid, and smooth user experience without having the top of the line specs available.
