In Agile development environments, where builds are deployed frequently, rapid changes increase the risk of introducing issues that may break existing functionality. Relying on manual regression testing in such scenarios is highly inefficient and impractical—especially when hundreds of test cases must be executed repeatedly throughout the development cycle.
In the absence of automated scripts, all test execution during UAT must be conducted manually—resulting in excessive time consumption, escalates workload and stress, This manual burden becomes critical when changes or bug fixes require repeated regression cycles.
Initiating test automation early ensures
early bug detection, prevents breaking
existing features, supports agile rapid
deployment, and reduces repetitive
manual testing—resulting in faster
delivery, improved quality, and reduced
development risks.
In most cases, test automation enhances
project results by increasing both speed and
reliability
Bugs found late in the cycle are more costly and time-consuming to fix. The late fixes may break the stable features while the full manual regression testing at this point is not possible, thus increasing the risk of defects slipping into the production environment.
Manual regression and repetitive testing slow down the project milestones such as development, testing and UAT.
Delays, frequent bugs re-open, not effective UAT process and inconsistent test results may occur—leading clients to perceive the project as poorly managed, and lacking in quality assurance.
Requires more testers to perform manual testing and bug validation in order to meet tight deadlines.
Repetitive, manual tasks, multi-tasking testing can lead to burnout and decreased motivation among QA staff.
