Optimizing Citizen Experience: Automated Regression Testing for the Public Sector

Government agencies are constantly striving to update their IT infrastructure to keep up with evolving technology trends and improve the delivery of services to their constituents. However, these digitization efforts often involve complex multi-vendor software implementations or iterative rollouts of software versions, which can pose unforeseen challenges and risks to the overall usability and user experience (UX) of the final application.

Interconnected systems and complex software implementations create a testing labyrinth for government agencies. Changes to one component can impact others, causing unforeseen glitches or bugs. The limited visibility into these projects makes things even more complicated, as problems are often discovered late in development.

Regression testing, i.e. re-evaluating the entire system after code changes, plays a crucial role in mitigating these risks. Traditionally, manual testing involves the repeated execution of test cases, which takes up a lot of time and resources. This approach is particularly challenging for government agencies due to:

• Highly regulated nature: Meticulous testing is required to ensure compliance with various standards, which increases complexity and documentation burdens.
• Interconnectedness: It is difficult to isolate and test individual components without impacting the entire system is difficult, creating a convoluted testing landscape.
• Resource constraints: Limited testing environments, personnel, and budgets further hamper the efficiency of manual testing.

These limitations can delay the test cycle, hinder development, and jeopardize system stability, as government projects are dynamic projects with frequent updates. Manual testing becomes increasingly inefficient and time-consuming as the volume of test cases grows. This underscores the need for alternative solutions, such as automated regression testing, to ensure efficient and comprehensive testing in government digitalization projects.

How automated regression testing enhances government operations

Automating regression testing can alleviate challenges by streamlining test execution, reducing human intervention, and increasing test coverage. Government agencies can make their regression testing more efficient and reliable by automating repetitive tasks and minimizing the risk of human error.

Repeatability

In agile projects, regression tests need to be performed repeatedly as new features are added or bugs are fixed. Manual testing becomes increasingly time-consuming as the number of test cases increases. Automated tests, on the other hand, can be performed efficiently and repeatedly and ensure comprehensive test coverage without manual intervention.

No human intervention

Once automated, test cases can be scheduled or triggered on demand, allowing tests to be run around the clock without human assistance. This ensures consistent and reliable test execution, regardless of the time of day, and results in shorter turnaround times for certifying new builds.

Faster turnaround time

Automated regression testing is much faster than manual testing, especially as the number of test cases increases. While manual testing can take days to cover a comprehensive test suite, automated tests can certify a new build in a matter of hours, speeding up the entire development process. With regression testing, bugs can be tracked down in the early stages of the software development cycle, saving the government from having to invest in maintenance efforts, both in terms of time and cost to fix the bugs that arise.

Increased coverage

Automated testing can cover the same test cases for different combinations of browsers, operating systems, and devices simultaneously. Tools like BrowserStack allow testers to run regression tests across multiple platforms in a fraction of the time it would take manually, ensuring comprehensive test coverage and faster detection of underlying issues.

Efficiency

Automated regression testing eliminates the potential for human error associated with manual testing, resulting in more accurate and reliable test results. This efficiency leads to higher quality software releases and increased user satisfaction.
