Let’s build our suite now.



Building Your Suite


Define Scope and Requirements

The first step towards building the test suite is to identify areas to automate and prioritize critical functionalities.

Identify Areas to Automate

Our priority here is to evaluate the software application to identify repetitive tasks, frequent regression scenarios, or time-consuming manual processes that can be automated. We need to look out for the areas commonly targeted for automation including functional testing, regression testing, integration testing, and performance testing.

E.g. for an e-commerce website, the areas to automate can be:

The checkout process on the e-commerce website involves multiple steps, such as adding items to the cart, entering shipping and payment details, and completing the purchase. Since the checkout process is frequently used by customers and involves repetitive tasks, it is a prime candidate for automation.

Prioritize Critical Functionalities

Determine the critical functionalities or features of the application that are essential for its functionality, stability, or user experience. Consider factors such as business impact, customer requirements, and risk analysis to prioritize functionalities for automation. Critical functionalities may include core features of the application, frequently used workflows, or areas prone to defects or regression.

E.g. Among the various functionalities of the e-commerce website, the checkout process is critical for ensuring a seamless user experience and facilitating transactions. Automating the checkout process can help reduce errors, improve efficiency, and enhance customer satisfaction. 

Define testing goals and expected outcomes

The following goals can be identified with expected outcomes.


Goals Outcome
Ensure Functionality Increased Efficiency
Validate Data Entry Improved Accuracy
Test Error Handling Enhanced Reliability
Verify Integration Better User Experience
Evaluate Performance Cost Savings


Choose Your Tools and Framework

Selecting the right automation tools is a critical step in establishing an effective test automation strategy. It involves researching and evaluating various options based on several factors such as compatibility with your technology stack, ease of use, features, and cost.

Ensure that the tools support the programming languages, frameworks, and platforms used in your software development process.

Choose automation tools that offer intuitive interfaces, clear documentation, and robust community support. 

Evaluate the features offered by each automation tool and determine whether they align with your testing requirements. Look for features such as cross-browser and cross-platform compatibility, support for parallel testing, integration with CI/CD pipelines, and robust reporting capabilities.

Cost is also a factor to consider, especially for organizations with budget constraints. While some automation tools offer free or open-source versions, others may require a subscription or licensing fees. 

Popular automation tools like Selenium WebDriver, Appium, Cypress, and TestCafe are widely used and trusted by software development teams worldwide. Selenium WebDriver is a popular choice for automating web applications, while Appium is preferred for mobile application testing. Cypress and TestCafe are renowned for their ease of use and powerful capabilities in end-to-end testing scenarios.

Write Your Test Cases 

To prepare test cases for automation, start with simple, clear, and well-structured tests. Clearly define the test objective, steps to execute, and expected results in a standardized format. Use techniques like data-driven testing to parameterize test cases and cover multiple scenarios efficiently. Additionally, consider adopting Behavior-Driven Development (BDD) principles to write test cases in a human-readable format that aligns with business requirements.

Emphasize maintainability and reusability by designing modular test cases that can be easily updated and reused across different test scenarios. By following these practices, you can ensure that your test cases are well-prepared for automation, facilitating the development of a robust and scalable test automation suite.



Running and Maintaining Your Suite


Set Up Your Testing Environment

Setting up your testing environment is essential for successful test automation. Here's how to ensure compatibility with testing tools and applications, and effectively manage test data and environment configurations:

Compatibility with Testing Tools and Applications

Identify the testing tools and applications required for your automation project, such as Selenium WebDriver, Appium, or Cypress for web testing, and Appium or Espresso for mobile testing. Ensure that the testing tools are compatible with the technologies and frameworks used in your application development, such as programming languages (e.g., Java, Python, JavaScript), web browsers, and operating systems. Install and configure the necessary drivers, libraries, and dependencies for the testing tools to interact with your application's UI elements and backend services.

Manage Test Data

Define the test data required for executing test scenarios, including input values, expected outcomes, and test conditions. Organize and manage test data in a structured format, such as spreadsheets or databases, to facilitate data-driven testing. Use techniques like data parameterization to dynamically inject test data into test scripts, enabling the execution of multiple test scenarios with different datasets. 

Environment Configurations

Set up and configure the testing environment to mirror the production environment as closely as possible. This includes configuring hardware, software, network settings, and other infrastructure components. Use virtualization or containerization technologies, such as Docker or virtual machines, to create isolated testing environments that can be easily replicated and managed. Implement version control and configuration management practices to track changes to the testing environment and ensure consistency across different test environments (e.g., development, staging, production). Automate environment setup and configuration using tools like Ansible, Puppet, or Chef to streamline the provisioning and management of testing environments.


Run and Monitor Tests

To effectively run and monitor tests in your automation project, follow these key steps:

Choose Appropriate Scheduling and Execution Options

Determine the optimal scheduling and execution strategy for running automated tests based on project requirements, resource availability, and testing objectives. Consider parallel execution to speed up test execution by running multiple tests simultaneously across different environments or configurations. 

Integrate with CI/CD Pipelines for Continuous Testing

Integrate automated tests into your Continuous Integration/Continuous Deployment (CI/CD) pipelines to enable continuous testing throughout the software development lifecycle. Trigger automated tests automatically whenever new code is committed to the version control system, ensuring that changes are validated promptly and consistently. Incorporate feedback mechanisms into the CI/CD pipeline to notify developers and stakeholders of test results, including pass/fail status and any defects identified. 

Monitor Test Results and Identify Failures Promptly

Implement robust test result monitoring mechanisms to track test execution progress and outcomes in real-time. Utilize test reporting and logging tools to generate comprehensive test reports that provide insights into test coverage, pass/fail status, and test execution metrics.


Maintain and Improve Your Suite

Maintaining a test suite for automation is essential to ensure the reliability and effectiveness of automated testing processes. Regular updates and refinements to test scripts and frameworks allow for adaptation to changes in software functionality, enabling early detection of regressions and defects. By optimizing test execution and eliminating redundant or obsolete tests, maintenance efforts contribute to efficient testing workflows and cost savings over time. Furthermore, continuous improvement initiatives driven by test suite maintenance foster a culture of quality enhancement and drive higher levels of software quality and customer satisfaction.

Update Tests as Functionalities Evolve

Regularly review and update automated tests to reflect changes in application functionalities, user interfaces, or business logic.

Collaborate closely with developers, product owners, and other stakeholders to stay informed about upcoming changes and prioritize test updates accordingly.

Conduct regression testing after each software release to ensure that existing functionality remains intact and identify any regressions caused by recent changes.

Continuously Refine and Improve Automation Efficiency

Analyze test execution results and identify opportunities to optimize and streamline test automation processes.

Refactor test scripts and automation frameworks to improve readability, maintainability, and reusability. Eliminate duplicate code and adopt design patterns that promote modularization and scalability.
