(4) Bridging the Skill Gap

Proficiency in automation tools and scripting languages is essential for successful automation testing. However, team members may lack the required skills, posing a barrier to seamless integration and execution of automation processes.

To overcome the above challenge, invest in training for automation tools like Selenium, Cypress, or Playwright. Alternatively, consider utilizing codeless automation tools such as Testsigma to empower team members with varying skill levels to contribute effectively to test automation.

Key Components for Starting Automation:

While automation testing holds immense potential, mastering it requires dedication and continuous learning. Let's learn the essential components for getting started with the test automation:

(1) Correct Strategy 

The first step in automation testing is developing a solid plan. Whether you're using code-based or codeless tools, starting with a clear plan is crucial. Determine which test cases to automate first. 

Example: It's best to start with repetitive and high-risk test cases, as they offer the greatest return on investment. A well-thought-out strategy ensures that your automation efforts are effective and efficient.

(2) Strong Programming Skills: 

Proficiency in programming languages such as Java, JavaScript, Python, or Ruby is essential for automation testers. Having strong programming skills helps testers write robust and maintainable test scripts, handle exceptions, and implement complex logic, thereby enhancing the reliability of the automation suite.

Example: The choice of language often depends on the automation tool being used. For example - Selenium, a popular automation tool, supports multiple languages including Java, C#, and Python but Cypress just supports Javascript. So, important to consider programming language before choosing any tool.

(3) Clear Testing Fundamentals: 

Automation testing isn't just about writing code. It requires a deep understanding of testing principles. You need to know what can be covered in smoke tests or regression packs. 

Example: Smoke tests are a subset of test cases that verify basic functionality, while regression packs are comprehensive suites ensuring that new changes don't negatively impact existing functionality. Knowing which tests to run daily and which to execute with each build is crucial for maintaining software quality without overwhelming the testing process.

(4) Understanding of setting CI/CD Pipeline: 

With the integration of automation testing with the CI/CD pipeline, you can ensure they run seamlessly with every code change and provide instant feedback for quicker defect resolution. Additionally, you can also schedule your test to run daily.

With Testsigma, you can integrate your automated tests into your existing CI/CD and DevOps pipeline to test continuously for faster software releases.

Example: Knowledge of setting up CI/CD pipelines is essential for automation testers. Tools like Jenkins, GitLab CI, GithubActions, and CircleCI can be easily configured to trigger automated tests.

(5) Framework Creation: 

Creating a scalable and maintainable automation framework is a key skill for automation testers. A well-designed framework allows for easy integration of new test cases, parameterization, and configuration management. 

Example: A robust framework typically includes wrapper classes to abstract complex operations, making test scripts simpler and more readable. It also supports parallel testing, reducing overall testing time and providing faster feedback.

Automation Testing Workflow

The Automation Testing Workflow represents the process of automation testing from the planning to the analysis phase. Below are the workflow steps that are involved in the process of automation testing:

(1) Test Planning: 

In this phase, teams identify test cases to automate based on criteria such as frequency of execution and criticality.

Example:  You are working on a new e-commerce platform. You should identify critical functionalities, such as user registration, product search, and checkout processes to automate. These functionalities are important for the platform's performance and user experience.

(2) Script Development:

In this phase, automation engineers write scripts to automate the execution of test cases using programming languages and automation tools.

Example: Automation engineers create scripts to test user registration with different inputs, search for products with various filters, and complete the checkout process with varying methods of payment but using tools/libraries and not doing it manually.

(3) Test Execution: 

In this phase, automated scripts are executed against the application or system under test to validate its functionality and performance. Once the scripts are developed, they are executed against the platform. 

Example: Automated tests verify whether user registration is successful, product search returns accurate results, and the checkout process completes without errors. This phase ensures that the functionalities behave as expected under different conditions.

(4) Continuous Integration and Deployment (CI/CD):

In this phase, the automation scripts are integrated into the continuous integration and deployment pipeline. Continuous Integration (CI) ensures that changes made in the codebase are automatically tested, integrated, and verified frequently. Continuous Deployment (CD) takes it a step further by automatically deploying code changes to production environments after passing through the automated tests. This seamless integration and deployment process streamlines the development workflow and enables rapid feedback loops.

Example: Once the automated tests are successfully executed, the CI/CD pipeline automatically triggers the deployment of the updated code to the staging or production environment, ensuring that new features or bug fixes are promptly available to users.

(5) Feedback Loop and Iteration:

Based on the analysis of test results and monitoring data, the development team iterates on the codebase to address any identified issues or enhance existing features. This iterative process of development, testing, and deployment ensures that the application evolves to meet changing requirements and user expectations.

Example: Feedback from automated tests and user feedback helps the development team to refactor the checkout process for better performance and usability. They implement the necessary changes, run automated tests to validate the modifications, and deploy the updated code through the CI/CD pipeline.

Conclusion

While automation testing can present challenges, a strategic approach combined with continuous learning can make it more manageable and rewarding. By understanding and addressing the components and challenges of automation testing, teams can leverage their full potential to deliver high-quality software faster and more reliably.
