Hello MailingR, it's Jarek 👋
Unit testing is a fundamental aspect of Android app development that every Android developer should embrace.
Just like the common fear of mathematics, some developers may feel hesitant or unsure when it comes to unit testing. However, it's time to address the question that has lingered in our minds – is unit testing really beneficial for Android development?
Let's start by acknowledging the truth – not every developer will spend their days solely writing unit tests.
Yes, I understand that.
However, let's also explore the brighter side of unit testing.
It goes beyond just verifying individual units of code;
it fosters a culture of quality and reliability in your Android apps.
By writing unit tests, you develop the skill of breaking down complex app functionalities into manageable, testable parts, which ultimately results in more robust and maintainable code.
With proper testing, you gain the ability to identify bugs and issues early in the development process, saving time and headaches down the road.
Testing ensures that your app's behavior remains consistent across different devices and Android versions, providing a seamless experience to users, no matter where they are in the world.
Now, let's bring unit testing closer to real-world scenarios. It surrounds us every day in Android development – from verifying that a specific function returns the expected output to ensuring that different parts of your app work harmoniously together.
Through unit testing, you gain the confidence to iterate and improve your code with ease, knowing that you have a safety net of tests to catch any regressions.
In the long term, unit testing saves your time!
While you may not write tests for every single line of code, the skills and mindset you cultivate through unit testing will be invaluable throughout your app development journey.
Now, if you're eager to learn more about unit testing but don't know where to start, fear not!
I have prepared two special things for you: - Testing Coroutines Masterclass (workshop recording) - Android-specific stuff. It covers everything from the basics to advanced techniques, helping you master the art of unit testing in clean architecture and MVVM. Testing Compose viewmodels included.
- JUnit5 for Android developers - introductory course To jUnit5 ecosystem
Remember, learning is not just about reaching an end goal; it's a continuous journey. So, have fun, explore, and embrace the challenges along the way. Don't be afraid of unit testing; it's your ally in crafting exceptional Android apps.
