Along with knowing the different Agile methodologies for testing, you must also have a keen understanding of the core methodologies used in Agile software testing today.

Core Methodologies in Agile Software Testing

In this section, you will explore three critical methodologies, each focusing on enhancing software quality through early feedback, continuous improvement, and fostering collaboration among developers, testers, and stakeholders. 

These methodologies bridge gaps between technical teams and stakeholders by integrating feedback early, ensuring alignment with business goals, and promoting shared understanding throughout the development process.

Test-Driven Development (TDD)

TDD is a development practice where tests are written before writing the actual code. It follows a "test-first" approach to guide coding and ensure the functionality meets the desired outcomes.

Here’s how you implement it:

1. Write a test for a specific functionality.
2. Run the test to ensure it fails (since the functionality isn't implemented yet).
3. Write the minimum code required to pass the test.
4. Refactor the code for optimization while ensuring the test still passes.
5. Repeat for additional functionalities.

These are some of its benefits:

• Reduces bugs by catching issues early.
• Enhances code quality and maintainability.
• Encourages modular and testable code design.

Example: A developer writes a unit test to validate a login feature before implementing the authentication logic.

Acceptance Test-Driven Development (ATDD)

ATDD focuses on writing acceptance tests based on user stories and requirements before development begins. These tests define the criteria for a feature to be considered complete and acceptable.

Here’s how you implement it:

1. Collaborate with developers, testers, and stakeholders to define acceptance criteria.
2. Translate acceptance criteria into test cases.
3. Develop the functionality to satisfy the tests.
4. Validate that the implementation passes the predefined acceptance tests.

These are some of its benefits:

• Aligns development with business goals.
• Improves communication and collaboration among team members.
• Ensures the software meets user requirements.

Example: Before developing a shopping cart feature, the team defines an acceptance test: "A user can add an item to the cart and view the total price."

Behavior-Driven Development (BDD)

BDD builds upon ATDD by using natural language to define application behavior. It ensures all stakeholders (technical and non-technical) can understand the system's behavior through shared specifications.

Here’s how you implement it:

1. Use a domain-specific language (e.g., Gherkin) to write behavior scenarios in a "Given-When-Then" format.
2. Develop tests and code to satisfy the behavior scenarios.
3. Run automated tests to validate the implementation.

These are some of its benefits:

• Enhances collaboration between technical teams and stakeholders.
• Provides clear, unambiguous documentation of expected behavior.
• Simplifies understanding of requirements for all parties.

Example: A BDD scenario for a login feature–given the user is on the login page, when they enter valid credentials and click "Login," they are redirected to their dashboard.

These practices help Agile teams ensure higher-quality software through early testing, iterative improvements, and continuous feedback loops.
