Maestro, Android Modern UI Testing

Maestro is the simplest and most effective mobile UI testing framework. Maestro is built on learnings from its predecessors (Appium, Espresso, UIAutomator, XCTest) and allows you to easily define and test your Flows.

  • Built-in tolerance to flakiness. UI elements will not always be where you expect them, screen tap will not always go through, etc. Maestro embraces the instability of mobile applications and devices and tries to counter it.
  • Built-in tolerance to delays. No need to pepper your tests with sleep() calls. Maestro knows that it might take time to load the content (i.e. over the network) and automatically waits for it (but no longer than required).
  • Blazingly fast iteration. Tests are interpreted, no need to compile anything. Maestro is able to continuously monitor your test files and rerun them as they change.
  • Declarative yet powerful syntax. Define your tests in a yaml file.
  • Simple setup. Maestro is a single binary that works anywhere.

 In this video, I’ve asked Zhanibek Marshal to join me and share his experience using this framework.

Hope you enjoy and do not forget to follow me on Medium and YouTube to get notified when there is a new topic.

How to make and use BOM (Bill of Materials) dependencies in Android projects

You’ve probably come across the BOM term if you’ve worked with big libraries like Jetpack Compose or Firebase. But what exactly is a BOM dependency? Why is it important? And how can we create our own BOM for our SDKs and their dependencies? Let’s find out.

As an example, we can take a look into the Jetpack Compose BOM dependency’s package contents. For this purpose, we can open Google’s Maven repository and search for it. Inside you can see only a POM file. Let’s see what’s inside.


Using the Gradle Version Catalog in Android projects

The Gradle build system Version Catalog is a powerful tool that can help you manage dependencies and plugins in your Android projects. Instead of hard-coding dependency names and versions in individual build files and updating each entry whenever you need to upgrade a dependency, you can create a centralized version catalog of dependencies that various modules and even projects can reference in a type-safe way with Android Studio assistance. This makes managing dependencies and plugins easier when you have multiple modules or projects.
