Your team has just finished developing a web app and is ready to take it to market. You're confident your product meets the highest usability, functionality, security, and performance standards. There's no need for testing, right? Not quite. Web app testing is essential to ensure the quality and security of your web applications.
There are two kinds of testing: manual and automated. Manual testing involves a team running tests to catch any errors, while automated testing uses algorithms. With the increase in the scale and scope of testing in DevOps, the need for automated testing for web apps is greater than ever.
Web app automated testing is the process of using software tools to execute pre-scripted tests on a web application before it is released into production. This approach ensures that the app performs as expected, functions correctly, and remains bug-free even after updates or changes. Automated testing can save time and resources by quickly identifying issues that would be hard to find manually.
Here are key benefits of web app test automation:
Let’s go through automated testing types and their goals that you can perform for your web applications:

Effective automated website testing requires a well-structured approach and adherence to best practices to ensure efficiency and maintainability. Before you start automating your web application tests, draft a test automation strategy to keep you on track.
Clearly outline the specific requirements of your web application to ensure your testing aligns with the application's goals and functionalities. Understanding these requirements helps in designing relevant test cases that cover all necessary aspects of the application. This step is crucial for identifying key areas that need thorough testing and avoiding unnecessary tests.
Example: For an e-commerce web application, identify specific requirements such as secure payment processing, seamless navigation between product categories, and responsive design on mobile devices. These requirements guide the creation of test cases to ensure critical functionalities work as intended.
Determine which tests are most beneficial to automate, such as regression, performance, and functionality tests. Automating the right types of tests ensures you maximize the efficiency and effectiveness of your testing efforts. Focus on repetitive, time-consuming tests that benefit most from automation.
Example: For the same e-commerce application, automate regression tests for the checkout process, performance tests for page load times under high traffic, and functionality tests for search and filtering features. These tests provide the most value by ensuring core functions remain reliable.
Select a test automation tool that best suits your requirements, goals, and team resources. Ensure the tool integrates well with your existing processes and supports the technologies used in your web application. Consider factors like ease of use, community support, and scalability when choosing a tool.
Consider the maintenance requirements of your automated tests to avoid accumulating unmanageable test cases. Opt for a tool and strategy that supports easy updates and modifications. Regularly review and update test scripts to keep them relevant and effective as the application evolves.
Example: Schedule regular reviews of automated test scripts to update them based on changes in the application. For instance, if a new payment gateway is integrated, ensure test scripts are updated to include validation for this new feature, preventing outdated tests from causing false positives or negatives.
Begin with a small set of automated tests and expand as you gain confidence. This approach helps prevent the burden of maintaining an excessive number of test cases. Gradually scaling your efforts allows you to refine your processes and ensure stability before taking on larger automation projects.
Aim for a balanced level of automation to achieve optimal return on investment.
Maintain clear communication within the team to align testing goals and ensure everyone is informed about the automation processes and updates. Regular meetings and updates help keep the team on the same page and facilitate collaborative problem-solving. Documentation of processes and changes is also essential for transparency and knowledge sharing.
Regularly review and optimize test scripts to enhance their efficiency and effectiveness. Remove redundant tests and update scripts as the application evolves. Efficient test scripts reduce execution time and improve the overall performance of your automated testing suite.
Example: Regularly analyze test execution reports to identify and remove redundant or obsolete tests. For instance, if multiple tests cover the same login functionality, consolidate them into a single, efficient test script, reducing execution time and maintenance effort.
Integrate automated testing with continuous integration (CI) pipelines to ensure regular and consistent testing with every code change. This practice helps in early detection of defects and ensures that new code integrates smoothly with the existing application. Automated tests running in a CI pipeline provide immediate feedback to developers, allowing for quick corrections.
Stay informed and continuously improve your test automation strategy by accessing educational resources, such as guides and tutorials on web automation. Keeping up-to-date with the latest trends and best practices in test automation helps you refine your strategies and make informed decisions. Leverage online courses, webinars, and industry publications to enhance your team's skills and knowledge.
Integrating automated testing into an existing web project involves several crucial steps to ensure comprehensive coverage and efficient testing. Here’s how to start creating automated tests for software that currently lacks automation.
First, familiarize yourself with the website and its features. This involves navigating through the site and understanding its structure and functionality. Creating a mind map of the site's layout, including its pages and features, can be highly beneficial for visualizing the testing scope.
Gather data from the marketing or analytics team to understand user behavior and common navigation paths. Tools like Google Analytics can provide valuable insights into how users interact with the site. This data helps prioritize which test scenarios to automate first, focusing on maximizing efficiency and impact.
Start by automating the most common end-to-end use cases. For instance, in an e-commerce application, a typical user journey might include:
Homepage -> Search Results -> Product Information -> Customer Login/Registration -> Payment Information -> Order Verification
The initial goal is to ensure the purchasing flow is seamless, rather than testing every page in detail. By focusing on the primary user paths, you can build a "smoke regression pack" that covers the most critical functionalities.
Expand the smoke regression pack by incorporating more detailed functional regression scenarios. Use mind maps and the state transition testing approach to identify additional features and their interactions, ensuring broader feature coverage rather than just test coverage.
Identify potential entry points such as the homepage, product detail pages, or SEM-specific landing pages. Analyze each page to understand its initial state and how users might interact with its components. Mind maps can help visualize these interactions and plan the test cases.
Define triggers that change the state of the application, such as submitting a form or clicking a button. Alongside each trigger, specify assertions to verify that the application behaves as expected. For example, after a successful login, assert that the user is redirected to the dashboard.
While manual testing remains crucial, leveraging automation saves time, money, and resources. It enhances feedback cycles, expands test coverage, and helps bring products to market efficiently and cost-effectively.
Combine automated tests with manual methods like exploratory and functional testing. Human oversight ensures a high-quality user experience and deepens team members' understanding of the product.
Outsiders can spot bugs that in-house teams might miss due to their familiarity with the application. External testers offer objective insights, are cost-effective, and fit well with agile methodologies, allowing DevOps teams to focus on development.
A diverse community of professional testers can uncover subtle, unique bugs. Crowdsourced testing provides extensive coverage, quick turnaround times, and a user-centric perspective.
