Let’s further discuss, what is the process to conduct web application testing.

How to Conduct Web Application Testing (6-step Process)

Here’s a 6-step testing process that the QA team performs during a web application testing process:

  1. Plan Your Testing Strategy

    Begin by reviewing your web application’s requirements, specifications, and any other relevant documentation to understand its intended behavior, features, and functionality. Once you have a solid grasp of the application’s requirements, you can determine the scope, objectives, and timeframe for testing. Assess the personnel, tools, and test environments needed for the testing process.

    Finally, create a test plan document that outlines the testing process, including the testing scope, objectives, resources, schedule, and deliverables.

  2. Develop Test Cases and Scripts

    Once you have planned a strategy to proceed, identify the features and functionalities that need to be tested. Develop test cases that cover each feature and functionality, describing the inputs, expected outputs, and pass/fail criteria. Write test scripts (for automated testing) or test steps (for manual testing) to execute the test cases. Generate realistic and varied test data to simulate different scenarios during testing.

  3. Set Up Test Environments and Tools

    When you have developed test cases, configure the necessary test environments, which may include multiple browsers, devices, and OS. Install and configure testing tools for manual or automated testing, such as Selenium, JUnit, or TestNG. Ensure that the test environments and tools are ready for the test execution phase.

  4. Execute Test Cases

    Run the test cases and scripts, either manually or using automated testing tools. Carefully document any defects or issues encountered during the testing process. Report these defects to the development team for resolution. Re-run test cases after defects have been fixed to ensure the issue has been adequately addressed.

  5. Evaluate Test Results

    Once the test cases are executed, analyze the test results to determine if the application meets the specified requirements and objectives. Assess the quality of the application based on the number and severity of defects discovered, the test coverage, and the pass/fail rate of test cases. Identify areas where additional testing may be needed to ensure the application’s reliability.

  6. Report and Communicate Findings

    Prepare a final test report that summarizes the testing process, the defects discovered and resolved, and any remaining known issues. Once the reports are made, the QA team shares the test report with relevant stakeholders and documents any lessons learned during the testing process to improve future testing efforts.

    Space-O Technologies follows a transparent testing process to ensure the best quality of our web applications. We also maintain effective communication and collaboration between the testing team, development team, and other stakeholders throughout the web-based testing process.

Let’s further check the main approaches used during the testing process.

What are the Approaches for Testing Web Applications?

Here are the two different testing techniques and tools used in web application testing.

  1. Manual Testing

    Manual testing is a process where testers manually execute test cases without using any automated tools or scripts. In this approach, testers simulate user interactions with the application to identify issues and verify that it meets the specified requirements. Manual testing is especially helpful in discovering usability and user experience issues, as it allows testers to experience the application from the user’s perspective.

  2. Some advantages of manual testing are:

    • Flexibility in adapting to changes in requirements or application behavior.
    • Ability to discover usability issues that might not be detected by automated testing.
    • No initial investment in automated testing tools or scripting.

    Tools for Manual Testing

    Although there are no specific tools required for manual testing, some tools can assist testers in managing and documenting their testing activities. For example:

    • TestRail: A test management tool that helps organize test cases, plan testing activities, and track test execution and results.
    • Jira: A popular project management tool that can be used to manage test cases, log defects, and track progress.
  3. Automated Testing

    Automated testing involves using tools or scripts to execute test cases automatically. The test automation approach allows for more efficient and accurate testing, as it can run multiple tests simultaneously, quickly identify issues, and provide detailed reports on test execution. Automated testing is especially useful for regression testing, performance testing, and repetitive tasks that would be time-consuming and error-prone if done manually.

  4. Some advantages of test automation are

    • Faster test execution, leading to reduced testing time.
    • Improved test coverage and accuracy by minimizing human error.
    • Consistency in test execution, making it easier to identify and fix issues.

    Tools for Automated Testing

    Some popular tools used in test automation for web applications include:

    • Selenium: A widely-used open-source tool for automated functional testing of web applications, supporting various programming languages and browsers.
    • JMeter: An open-source tool for automated testing, measuring the load handling capabilities and response times of web applications.
    • OWASP ZAP: An open-source tool for web application security testing, identifying vulnerabilities and potential threats in web applications.
