Why Use Automation in Agile

The Agile development methodology revolves around short iterative cycles, continuous revisions, and swift releases. With constant collaboration and communication among cross-functional teams, including Scrum masters, product owners, business analysts, developers, and quality assurance professionals, Agile aims to deliver valuable software to customers. However, the accelerated nature of Agile often poses challenges in testing new and existing functionality within the limited time of each sprint.

Automation in Agile ensures the quality of both new and existing functionality. Regression testing is employed to validate the existing functionality, ensuring that it is not broken by new features. On the other hand, the new functionality must be fully operational and error-free within each sprint cycle. By executing automated test scripts, Agile teams can obtain rapid and reliable feedback, enabling them to identify and rectify any issues promptly.

Here are five key considerations before starting automation in Agile:

  • Automating repetitive tasks: Identify repetitive tasks that can be automated to save time and effort.
  • Automating critical areas of the product: Focus on automating test scenarios that address the critical areas of the product.
  • Automating critical paths of the product: Prioritize automating the critical paths of the application to ensure its core functionality is thoroughly tested.
  • Automating Data Driven tests: Automate tests that require various sets of data to verify the application's behavior under different conditions.
  • Automating time-consuming human intervention steps: Streamline the testing process by automating time-consuming steps that involve manual intervention.


Methods of Agile Automation Testing

When it comes to Agile automation testing, the traditional focus is often on automating the user interface (UI). However, automation can be implemented at three different layers: the unit layer, service layer, and UI layer. Each layer offers unique advantages and contributes to delivering a robust and reliable product to the market.


The Test Pyramid

The test pyramid is a visual representation of the distribution of automated tests across different layers. It includes the UI, service, and unit layers, each serving a specific purpose in Agile automation testing. Here's an overview of the test pyramid:

  • Unit layer: The unit layer forms the foundation of the test pyramid, where developers create and execute unit tests. These tests focus on small units of code and provide quick feedback if any errors occur.
  • Service layer: The service layer involves automating business logic and web services, allowing the exchange of information through requests and responses. It enables the automation of APIs and streamlines the testing process by bypassing steps that have already been automated at the UI layer.
  • UI layer: The UI layer represents the top layer of the test pyramid and involves automating test scripts that interact with the application's user interface. Testing at the UI layer ensures the application's behavior and user experience are thoroughly validated.

By automating tests at all three layers, Agile teams can leverage the advantages of each layer to ensure comprehensive test coverage and efficient testing practices.


Unit Testing

Unit testing plays a significant role in Agile automation testing, forming the largest part of the test pyramid. It involves creating and executing tests at the unit layer, focusing on small units of code. Developers use test frameworks like JUnit or TestNG to write unit tests and verify the functionality of individual code units.

Unit testing is often performed using the test-driven development (TDD) approach, where tests are written before the actual code implementation. This approach ensures that the code meets the desired requirements and enables developers to catch any errors or bugs early in the development process. By adopting TDD and performing unit testing, Agile teams can enhance code quality, promote faster development cycles, and facilitate continuous integration.


Service Layer Automation

The service layer in Agile automation testing is responsible for automating business logic and web services. It enables the exchange of information between different components of the application through requests and responses. Automating the service layer allows testers to validate the application's behavior without relying solely on the UI.

By constructing tests at the service layer, Agile teams can verify the functionality of APIs and business logic independently. This approach offers benefits such as faster test execution, increased test coverage, and the ability to isolate and debug issues more effectively. Additionally, automating the service layer reduces reliance on the UI layer, enabling testers to focus on specific functionalities and perform targeted testing.


UI Layer Automation

The UI layer automation involves automating test scripts that interact with the application's user interface. It allows Agile teams to simulate user interactions and validate the application's behavior, visual elements, and user experience. However, testing at the UI layer can be more time-consuming compared to the service and unit layers due to factors like network speed, test data inconsistencies and complexities in application interactions.

When automating at the UI layer, testers need to consider network speed, as it can impact the time required to load the application. Additionally, interactions with the application, such as clicking buttons or entering data into fields, determine when a test is complete. Despite the potential challenges, UI layer automation is crucial for validating the overall functionality and usability of the application.


Best Practices for Agile Automation Testing

To ensure the success of Agile automation testing, it is essential to follow best practices that optimize the testing process and promote the delivery of high-quality software. Here are some key best practices to consider:


Formulate a Plan Before Creating Automation Test Scripts

Before diving into automation, it is crucial to prepare and plan the automation process. Developing a comprehensive plan serves as a template for conducting automation within the Agile team. The plan should include considerations such as the scope of automation, test coverage, and the selection of appropriate automation tools.

By preparing and planning ahead, Agile teams can define clear objectives, identify potential challenges, and streamline the automation process. This ensures that the automation effort aligns with the Agile development goals and contributes to the efficient delivery of quality software.


Study What Scenarios to Automate

Automation should focus on automating high-value scenarios that contribute to reusability and provide significant testing coverage. It is essential to identify the most critical functionalities and prioritize their automation. By understanding which scenarios to automate, Agile teams can maximize the efficiency of their testing efforts and ensure thorough validation of the application.


Select the Best Tools

Selecting the right automation tools is crucial for successful Agile automation testing. Investing time in evaluating the capabilities of different tools in the market and understanding their suitability for the Agile environment is essential.

By choosing the best tools, Agile teams can leverage their capabilities to streamline the automation process, enhance collaboration, and achieve efficient testing practices.


Complete the Automation within the Sprint

To ensure the timely delivery of quality software, Agile teams should strive to automate test scenarios within the same sprint as the developed features. By incorporating in-sprint automation, teams can identify and address any issues or bugs early in the development process. This approach promotes faster feedback loops, enables continuous integration, and reduces the risk of accumulating technical debt.

Implementing in-sprint automation also facilitates better collaboration between developers and testers, as they can work together to ensure the automation of critical tests aligns with the sprint goals.


Setup a Test Automation Code Review Process

To maintain code quality and ensure the accuracy of automated test scripts, Agile teams should establish a code review process for test automation. Code reviews should involve someone other than the script author to provide a fresh perspective and identify any potential issues or improvements.

Test automation code reviews help maintain consistency, identify coding best practices, and improve the overall quality of the automated test suite. By incorporating this practice into the Agile automation testing process, teams can enhance the reliability and effectiveness of their automated tests.



Agile automation testing plays a vital role in delivering high-quality software within the dynamic and collaborative Agile development methodology. By embracing test automation, Agile teams can ensure the quality of both new and existing functionality while meeting the accelerated pace of Agile development.

A successful Agile automation testing approach involves automating tests at the unit layer, service layer, and UI layer. Each layer offers unique advantages and contributes to comprehensive test coverage, efficient testing practices, and the delivery of a viable product to the market.

To achieve effective Agile automation testing, it is crucial to follow recommended practices such as proper preparation and planning, understanding which scenarios to automate, selecting the right tools, implementing in-sprint automation, and establishing test automation code review. By adhering to these recommended practices, Agile teams can optimize their testing efforts, enhance collaboration, and ensure the delivery of high-quality software in an Agile environment.
