Classification of test types by purpose and scope (unit, integration, system, acceptance) to structure test strategies and responsibilities.
Test Levels describes the hierarchy of tests (unit, integration, system, acceptance) for systematic software quality assurance. It defines purpose, scope and responsibilities at each level and guides test strategy, automation effort and fault localization. It also supports prioritization and allocation of testing resources.
Average duration of full test runs in the CI pipeline.
Time from fault occurrence to identification of the affected component.
Proportion of source code covered by automated tests.
A set of fast unit tests to secure service logic and DTO transformations.
Runs against simulated payment gateways to validate end-to-end integrations.
Business-driven scenarios validate checkout flows with realistic test data.
Analyze existing test coverage and identify gaps
Define goals per test level (e.g. runtime, coverage)
Automate prioritized tests and integrate into CI
Monitor test metrics and continuously improve
