# 🧪 Spring Testing Mastery
Welcome to the **Spring Testing Mastery** repository! This project is a comprehensive guide and hands-on resource for mastering testing in Spring applications. It covers everything from unit testing to full integration testing using modern tools and best practices.
## 📚 What This Repository Covers
Spring provides powerful testing capabilities, and this repository demonstrates how to use them effectively across all layers of a typical Spring MVC application:
### 🎯 Controller Layer
- Test your web endpoints using **MockMvc**
- Validate HTTP requests and responses
- Simulate user interactions and verify controller logic
### ⚙️ Service Layer
- Use **Mockito** to mock dependencies
- Write clean and isolated unit tests
- Apply **Behavior-Driven Development (BDD)** principles
### 🗄️ Repository Layer
- Test data access logic with **Spring Data JPA**
- Use **Testcontainers** to spin up real databases for integration tests
- Ensure your repositories behave correctly with actual data
### 🧪 Testing Strategies
- **Unit Testing**: Isolate and test individual components
- **Slice Testing**: Focus on specific layers (e.g., `@WebMvcTest`, `@DataJpaTest`)
- **Integration Testing**: Verify end-to-end functionality across layers
### 🥒 BDD with Cucumber
- Write human-readable test scenarios
- Connect Gherkin syntax to Spring test logic
- Promote collaboration between developers and QA
### 🐳 Testcontainers
- Run real database containers (e.g., PostgreSQL, MySQL) during tests
- Eliminate environment inconsistencies
- Improve reliability of integration tests
## 🚀 Technologies Used
- Spring Boot
- JUnit 5
- Mockito
- MockMvc
- Cucumber
- Testcontainers
- Spring Data JPA
