Understanding Agile Testing Methodology

As the complexity of software development processes continues to grow, software testing methodologies must improve to keep pace. Agile testing is a new era technique that focuses on testing intelligently rather than exhaustively while still delivering high-quality products.

Agile Testing Approaches need a greater degree of communication between testers and developers. Throughout the software development cycle, testers must give remedial feedback to the development team. This is the era of continuous integration of testing and development methodologies.

Agile Testing Methodology – What Is It?

Agile testing is a mechanism of software testing that follows the agile development principles.The agile testing technique is consistent with iterative development, in which customers and testing teams continuously develop requirements. Customer needs are considered throughout development.

Agile testing is not a sequential process but rather a continuous one. Testing starts at the start of the project and continues to be integrated with development. The unifying goal of agile development and testing is to provide a high-quality product.

Principles of Agile Testing

The following are some agile testing principles:

Continuous testing is required: An agile team must test continually since this is the only way to assure the product’s continued advancement.

Continuous feedback- Agile testing gives continuous feedback, which is how your product satisfies business requirements.

Tests conducted by the whole team: With a typical software development life cycle, testing is done only by the test team; however, in agile testing, developers and business analysts also test the application.

Reduce feedback response time: Agile testing involves the business team in each iteration, and continual feedback reduces feedback response time.

Concise and clean code: Because all problems presented by the agile team are resolved inside the exact iteration, the code is kept clean and simple.

Less documentation: Agile teams use a reusable checklist, and the team concentrates on the test itself rather than on extraneous information.

Test-Driven: In agile methodologies, testing occurs concurrently with implementation, while in conventional processes, testing occurs afterward.

Defining characteristics of agile testing

1. Agile testing is unstructured compared to waterfall testing, and there is less preparation involved.
2. Agile testing is an excellent fit for smaller projects.
3. Waterfall testing applies to a wide variety of tasks.
4. Since testing starts from the beginning of the project, faults may be corrected throughout the project.
5. Agile testing requires very little documentation.
6. Each iteration of this technique includes a testing step. Regression tests may be conducted regularly to ensure that no new functions or logic are deployed.
7. Shippable product features are provided to the client after each iteration in agile testing.
8. Agile testing requires strong collaboration between testers and developers.
9. Each sprint concludes with a user acceptance test.
10. Testers must communicate with developers to assess needs and prepare accordingly.

Methods of Agile Testing

There are several agile testing approaches, including the following:

1- Development Based on Behavior (BDD)

Behavior Driven Development (BDD) facilitates communication amongst project stakeholders, ensuring that everyone understands each feature before the development process begins. Developers, testers, and business analysts are constantly exchanging examples-based communication.

“given/when/then” syntax is used to represent these scenarios referred to as Scenarios. Information about how one feature should behave in several situations with different input settings is included in scenarios. Because they contain both the specification and the inputs for automated testing, they are known as “Executable Specifications.”

2- Development Guided by Acceptance Tests (ATDD)

ATDD emphasizes the involvement of team members with varying viewpoints, including the customer, the developer, and the tester. Three Amigos meetings are held to design acceptance tests from the client, development, and testing viewpoints. Clientsare concerned with the issue to be addressed, development is concerned with how the problem will be handled, and testing is concerned with what may go wrong.

Acceptance tests provide the user’s perspective and explain how the system operates. Additionally, it assists in ensuring that the system operates as intended. Acceptance testing is sometimes automated.

3- Experimentation

The test design and execution phases are integrated into this style of testing. Exploratory testing places a premium on functional software above exhaustive documentation. Individuals and relationships take precedence over processes and instruments. Collaboration with customers is more valuable than contract negotiation.

 Exploratory testing is more flexible in the face of change. In this test, testers determine an application’s functioning via exploration. The testers attempt to understand the application and then build and execute test strategies based on their findings.

The Benefits of the Agile Testing Methodology

The following are the benefits of an agile testing approach:

• Agile testing results in less paperwork.
• It is adaptive and adaptable to changes.
• It enables the end-user to submit frequent input.
• Through regular meetings, problems may be resolved more effectively.

Conclusion

Agile testing enables early defect discovery and lowers the cost of errors by resolving them quickly. Additionally, this method results in a customer-centric approach since it prioritizes the delivery of a high-quality product as soon as feasible.
