Android Testing with Kotlin: Unit Tests, ViewModels, and UI Testing

मजबूत Android ऐप्लिकेशन्स लिखने के लिए केवल फ़ीचर्स लिखना ही काफ़ी नहीं है—इसके लिए यह सुनिश्चित करने के लिए एक ठोस परीक्षण रणनीति की आवश्यकता होती है कि आपका कोड सभी परिस्थितियों में काम करे। यह टेक्स्ट-आधारित कोर्स आपको Kotlin का उपयोग करके Android ऐप्स का परीक्षण करने की मूल बातें बताता है, जिससे आपको बग जल्दी पकड़ने और आत्मविश्वास के साथ डिप्लॉय करने में मदद मिलती है। You will transition from manual debugging to writing automated test suites for every layer of your application. Through step-by-step written explanations and practical code examples, you will master unit testing, dependency injection testing, and UI interactions, ensuring your architecture remains clean and maintainable. What you'll learn: - Understand the fundamentals of test-driven development (TDD) and the Android testing pyramid. - Write unit tests for ViewModels, Repositories, and LiveData using JUnit. - Implement test doubles, mocks, and fakes to isolate your code during testing. - Configure and run database tests for Room using in-memory databases. - Verify UI behavior and user flows using Espresso and modern Jetpack Compose testing principles. - Manage dependency injection in tests using Hilt to isolate components. - Test asynchronous Kotlin Coroutines and Flows to ensure correct background execution. The course begins with core testing concepts and terminology before guiding you through testing architecture layers from data to UI. You will study clear code snippets and written scenarios that demonstrate how to structure tests for real-world production apps. This course is designed for Android developers who want to learn automated testing from the ground up, with no prior testing experience required.
