I'm doing some work with Espresso and UiAutomator for Android testing and was curious how Maestro worked under the hood, so I cloned their git repo and dove into the code. This quick post shares what [...] ## Parameterized Android Tests with Burst 2.0 DevFeed: [Parameterized Android Tests with Burst 2.0]() Original publisher: [Read original article]() Author: Sam Edwards Published: 2024-10-31T15:52:32Z Content type: tutorial Language: en Sources: [Handstand Sam]() Topics: [Android](), [Kotlin Multiplatform](), [Kotlin](), [Compiler](), [Test coverage](), [APK](), [Firebase](), [Gradle]() Tags: [analysis](), [android](), [apk](), [firebase](), [gradle](), [instrumentation](), [kotlin](), [kotlin-compiler](), [kotlin-multiplatform](), [updates]() ### AI overview The article explains how Burst 2.0, a Kotlin Compiler Plugin, enables parameterized tests for Kotlin Multiplatform and Android instrumentation tests. It reports that the tests compile and execute successfully from the command line, while noting IDE support issues and a use case for statically computing test names for sharding. ### Source excerpt Parameterized tests allow you to write a test once, but allow it to be called with multiple parameters. This means it is creating more methods than you've written, but without you having to write and maintain each one individually. Here is a trivial example of writing a single test with TestParameterInjector, but having it run [...] ## Kotlin K2 FIR Quickstart Guide DevFeed: [Kotlin K2 FIR Quickstart Guide]() Original publisher: [Read original article]() Author: Sam Edwards Published: 2024-05-31T01:18:21Z Content type: tutorial Language: en Sources: [Handstand Sam]() Topics: [Kotlin](), [Compiler](), [Tooling](), [Code]() Tags: [2-0-0](), [analysis](), [compiler](), [guide](), [implementation](), [kotlin](), [tooling](), [updates]() ### AI overview A short guide to getting started with Kotlin K2's Frontend Intermediate Representation (FIR) for static analysis.

They are so easy to access from anywhere, and are globally available. It's hard to argue the utility of the amazing web platform. Compose for Web (WASM) is the latest technology in Kotlin Multiplatform and I'm pretty bullish about it. In this post [...] ## Adding Compose to Existing Espresso Tests with createEmptyComposeRule() DevFeed: [Adding Compose to Existing Espresso Tests with createEmptyComposeRule()]() Original publisher: [Read original article]() Author: Sam Edwards Published: 2023-04-12T13:46:30Z Content type: tutorial Language: en Sources: [Handstand Sam]() Topics: [Compose](), [Android](), [Instrumentation](), [test]() Tags: [android](), [compose](), [espresso](), [instrumentation](), [test](), [tests](), [updates]() ### AI overview This tutorial explains how to interact with Jetpack Compose elements in existing Android Espresso instrumentation tests without changing the test's existing Activity behavior. It recommends using createEmptyComposeRule() instead of rules that create or launch an Activity. ### Source excerpt As the documentation says, you can combine both Espresso and Compose in an Android instrumentation test. In order to interact with Compose in an instrumentation test you need a ComposeTestRule. Problem Typically you would create a ComposeTestRule with createComposeRule() in a part of your app that is compose only, but that will create a blank [...] ## Using Java Reflection with Kotlin Companion Objects DevFeed: [Using Java Reflection with Kotlin Companion Objects]() Original publisher: [Read original article]() Author: Sam Edwards Published: 2023-02-01T18:45:27Z Content type: tutorial Language: en Sources: [Handstand Sam]() Topics: [Kotlin](), [Java]() Tags: [how-to](), [java](), [kotlin](), [updates]() ### AI overview This tutorial explains how to use Java reflection to access and modify properties on Kotlin companion objects. It covers obtaining the companion object instance, working with the generated Java class, and accessing private backing fields. ### Source excerpt Kotlin companion objects allow you to add static data and methods associated with a class. This is similar to how Java has static fields and methods. The problem is that Java doesn't really know what a companion object it, so trying to access one using standard Java reflection might make you go crazy. 🤪 The [...]
