TDD in Android with Spek
summary
Shows how to set up Spek DSL on Android (requires JUnit 5 and a dev Maven for Spek 2.1.0), then practices TDD by writing unit tests first for an ArticleRepository interface with getArticles and fetchAndSync methods. Uses RX Java and fake data stores (success, empty, error, save) to assert behaviours: local emits first, remote merges later, empty local is ignored, and a custom empty result set exception signals total failure. Tests fail, implementation is added, and tests pass; warns Spek 2.1.0 is flaky on Android.
