🔷 Gradle Testing: Unlocking TestKit for Developers - Tom Koptel

Testing custom Gradle plugins is a critical step in ensuring their reliability, especially when developing for Android projects. This talk will focus on leveraging the Gradle TestKit framework to set up robust testing environments for custom plugins. Attendees will learn how to configure their projects effectively, enabling seamless plugin testing and integration.

Key topics include:

• Project Setup for Plugin Testing: Laying the groundwork for a Gradle plugin project with proper dependencies and configurations tailored for Android development.
• Using Gradle TestKit: A deep dive into functional testing with TestKit, including creating isolated test environments using GradleRunner and managing temporary directories for test builds.
• Testing Against Multiple Android Gradle Plugin (AGP) Versions: Techniques to ensure compatibility across AGP versions by dynamically injecting dependencies during tests.
• Advanced Testing Tools and Techniques: Exploring tools like Jacoco for code coverage metrics and live debugging of code under test.

🔷 Compile-time code generation with Kotlin Symbol Processing - Lajos Nyéki

In this talk, we will explore the advantages of compile-time code generation and how it can streamline development workflows by reducing boilerplate, improving performance and catching errors early. We’ll dive into Kotlin Symbol Processing (KSP), highlighting its modern approach compared to the older Kotlin Annotation Processing Tool (KAPT), and discuss why KSP is becoming the preferred choice for many Kotlin developers. To ground these concepts, we’ll walk through a real-world case study demonstrating how compile-time code generation with KSP can be applied to solve practical problems.
