Introduction to TDD

• Understanding the principles and benefits of Test-Driven Development
• Overview of the TDD process and its role in Agile development methodologies
• Introduction to the red-green-refactor cycle in TDD

Writing Test Cases

• Understanding the anatomy of a good test case
• Writing unit tests using testing frameworks like JUnit or TestNG
• Writing test cases that are independent, isolated, and deterministic

Test-Driven Development Workflow

• Following the red-green-refactor cycle in TDD
• Writing failing tests to define desired behavior (red phase)
• Writing production code to make the tests pass (green phase)
• Refactoring code to improve design and maintainability (refactor phase)

Unit Testing Techniques

• Writing testable code to facilitate unit testing
• Techniques for creating test doubles such as mocks, stubs, and fakes
• Test data management and using test data builders or factories

Test-Driven Development Patterns

• Understanding common patterns and practices in TDD
• Patterns such as Test Pyramid, AAA (Arrange-Act-Assert), Given-When-Then, and more
• Applying TDD patterns to write clean, modular, and testable code

Continuous Integration and TDD

• Integrating TDD practices into the continuous integration (CI) process
• Automating test execution and reporting using CI tools
• Understanding the role of TDD in maintaining code quality and preventing regressions

Refactoring and TDD

• Applying refactoring techniques within the TDD workflow
• Using TDD as a driver for improving code design and maintainability
• Balancing refactoring efforts with the TDD cycle

Test Coverage and Metrics

• Understanding the importance of test coverage and code metrics
• Measuring and analyzing code coverage using tools like JaCoCo
• Interpreting code metrics to identify areas for improvement

Acceptance Testing and TDD

• Incorporating acceptance testing into the TDD workflow
• Writing acceptance tests to define high-level behavior and requirements
• Using tools like Cucumber or JBehave for acceptance testing

TDD in Practice

• Applying TDD techniques in practical scenarios and real-world projects
• Case studies and examples of successful TDD implementations
• Overcoming challenges and adopting TDD in different development contexts

TDD and Legacy Code

• Techniques for introducing TDD in legacy codebases
• Strategies for writing tests for existing code and incrementally refactoring
• Handling dependencies and integration issues when adding tests to legacy systems

TDD and Design Principles

• Aligning TDD with software design principles, such as SOLID
• Leveraging TDD to drive clean and maintainable design
• Applying TDD to improve code cohesion, decoupling, and encapsulation

TDD Best Practices and Guidelines

• Exploring additional TDD best practices and guidelines
• Understanding the limitations and challenges of TDD
• Incorporating TDD practices into the software development process
