Test automation results in earlier detection of defects , improved testing efficiency, and increased test coverage while also reducing operational risk through reuse of automated test scripts without reliance on a manual testing workforce.
Many government agencies have established a centralized software testing organization that is staffed with experts in test planning, test script writing, test environment management, and test evaluation and analysis. These organizations often rely largely on manual testing, with test coverage limited by budgets and staffing. This usually increases risks to both schedules and application quality by leaving portions of systems untested and/or requiring additional time to deliver and address test results.
In most environments, some amount of manual testing should supplement and validate automated tests. However, a manual testing organization does not scale well: With a larger number of smaller, integrated apps being developed at a faster pace, and with increasing security requirements, manual testing alone would require a massive increase in the number of testers, diverting budgeted funds from other important initiatives. Even if the organization could hire enough manual testers, new testers may require months or years to become fully capable within the agency’s unique environment and testing strategies.
The solution to achieve quality tests without these limitations is to embrace a mature test automation strategy, particularly if your organization plans to tie automated testing to a CI/CD pipeline as part of a DevSecOps strategy.
