Agile Testing Methodology: Examples for the Agile Tester

In the world of software development, Agile methodology is a widely accepted approach for creating and managing projects. Just as the Agile development methodology breaks down larger elements of feature development into smaller, more manageable pieces (such as user stories, tasks, and technical requirements), an Agile testing methodology breaks down larger testing elements into smaller, more specific tests with a narrower focus on a specific user story, task, technical requirement, etc. In this article, we will explore the Agile testing methodology, its benefits, and provide you with five real-world examples of how it’s applied by Agile testers.

1. Agile Testing Supports Continuous Testing

Agile testing supports the principles of DevOps and continuous testing. Continuous testing is a crucial aspect of Agile development that focuses on improving product quality. In traditional development processes, testing often happens at the end of the development cycle. However, in Agile, testing is integrated throughout the entire process. This is commonly referred to as “shift left” testing.

Agile testers prioritize tests just as developers prioritize user stories. The aim is to get through as many tests as possible within each iteration. Automation tools are often employed to streamline the testing process. Using automation testing in software testing, Agile teams can efficiently manage repetitive and complex test cases, allowing for more frequent and thorough testing within each sprint. This method not only speeds up the validation process but also enhances the detection of defects early in the development cycle.  Continuous testing not only helps discover issues and bugs early in the development process but also allows for quicker bug fixes, as the issues are fresh in the developers’ minds. It also leads to better test coverage, resulting in improved product quality and safety.

2. What Does an Agile Tester Do?

In Agile development, testing and quality assurance become the shared responsibility of the entire team. Agile testers and developers must collaborate closely. Communication and collaboration are key components of this methodology.

Developers often use Agile testing methods like Test-Driven Development (TDD) where the test is written before the code. Agile testers and developers collaborate even before the user stories or requirements are set. This close partnership ensures that testing is integrated from the very beginning, avoiding the common practice of testing as a separate phase.

3. Understanding the Definition of Done

In Agile development, the “definition of done” is a shared, standardized understanding among the team that a specific user story has been completed. This definition includes acceptance criteria that must be met for the user story to be considered done. Testing plays a crucial role in validating the acceptance criteria, ensuring that the user story is indeed complete.

This understanding is vital for both Agile testers and developers. It helps track what has been tested and what defects still need resolution. This visibility ensures that everyone is aligned with the testing process and the definition of done.

4. Agile Testing Methodology: 5 Examples

There are several testing methods used in Agile testing, regardless of the specific Agile framework used, such as Scrum, XP, Kanban, or hybrid Agile. Here are five examples:

a. Test-Driven Development (TDD):

TDD starts with writing tests. Developers create unit tests and then write the code to make those tests pass. It’s often used for unit and component tests and can be automated, ensuring features work correctly.

b. Acceptance Test-Driven Development (ATDD):

ATDD starts with customer input on functionality. It involves writing user acceptance tests (UAT) and then developing the code to meet these tests. It’s essential for verifying that the product functions as users expect.

c. Behavior-Driven Development (BDD):

BDD connects development with business outcomes. Tests are included within user stories as scenarios or specifications, ensuring that the product’s functionality aligns with business goals.

d. Exploratory Testing:

This style of testing allows testers to follow their intuition rather than predefined scripts. Testers explore the application, recording their actions and findings. It’s typically used to find hidden risks within a product.

e. Session-Based Testing:

Similar to exploratory testing, but with a more structured approach. Testers begin with a mission and work towards specific goals.

5. Agile Testing Strategy

Unlike traditional development, Agile doesn’t typically involve extensive test plans. Instead, Agile testers require a flexible approach that can adapt to shifting requirements. An Agile test strategy is essential to guide the testing process. This strategy should include:

• Purpose (defined by the user story).
• Objectives (test cases).
• Scope (what needs to be tested).
• Methods (how tests will be run).

Agile testers often rely on tools like Helix ALM to create and manage their Agile test strategy, ensuring that testing aligns with development objectives.

Benefits of Agile Testing

Agile testing offers several advantages:

• Improved product quality.
• Faster error detection and resolution.
• Happy customers due to reliable products and stable releases.
• Better scope management and feature prioritization.

How to Manage Agile Testing

To ensure alignment within the Agile team and maintain visibility on the status of testing and issue resolution, it’s essential to use dedicated test case management tools. Helix ALM is one such tool that allows teams to create, execute, and track all types of tests within a single platform, providing a unified view of the entire Agile testing strategy.

Transition to Agile Testing

If you’re considering transitioning to Agile testing, tools like Helix ALM can make the process smoother. You can take advantage of a 30-day trial to explore how Helix ALM’s Test Case Management module can help you implement Agile testing effectively and achieve a holistic Agile testing strategy.

Conclusion

Agile testing is a methodology that aligns with Agile development, promoting continuous testing and collaboration. Agile testers use various testing methods to ensure product quality and deliver reliable software. By adopting Agile testing, development teams can improve product quality, reduce risks, and enhance customer satisfaction.
