Open Source Kotlin Software Testing Tools for Android

A library for in-process compilation of Kotlin and Java code, in the spirit of Google Compile Testing. For example, you can use this library to test your annotation processor or compiler plugin.

Booster is an easy-to-use, lightweight, powerful and extensible quality optimization toolkit designed specially for mobile applications. The primary goal is to solve quality problems with the increase of APP complexity, such as performance, stability, and package size, etc. Booster provides a collection of modules for performance detection, multithreading optimization, resources index inline, redundant resources reduction, resources compression, system bug fixing, etc. Using booster, the stability of application can be increased by 15% ~ 25%, and the package size can be reduced by 1MB ~ 10MB. Potential performance issues could be found by using Booster, for example, calling APIs that may block the UI thread or main thread, such as I/O APIs. Thread management has always been a problem for developers, especially the threads started by third-party SDKs, starting too many threads may cause OOM, fortunately, these issues can be solved by Booster.

Tests written with commented GIVEN, WHEN and THEN regions can be transformed by actually wrapping code within basic blocks called issues. This can occur in a nested fashion. Start with Test|TEST, that can wrap any issue. Given|GIVEN can wrap Given|GIVEN, When|WHEN; or Then|THEN issues. When|WHEN can wrap When|WHEN or Then|THEN issues. Then|THEN can only wrap Then|THEN issues. The Kotlin implementation supports 'suspend' functions: for any issue, there are two ("suspendable" and "nonsuspendable") kinds, that can be toggled between, while in the same foremost issue. Each issue can be labelled, and return values from corresponding code blocks can be referred to (or addressed, by nesting level), and searched using labels; wildcard matching is available too. Unlabelled given/then/when are not searchable, their return values are stored as the foremost issue's pending result. Supporting coroutines for unit or instrumented tests in Android is under development.
