Software Test Coverage Types: System, Unit, and Structural Explained #2206077 (License: Personal Use)

This infographic illustrates the evolution of test coverage across three key testing stages: System Testing typically achieves 60-70% coverage, Unit Testing reaches only 30-40% due to limited scope, while Structural Coverage-focused on code paths and branches-targets 100% completeness. The diagram uses color-coded bars and document icons to emphasize coverage gaps and testing depth.

Used on software engineering or QA resource pages to explain test strategy trade-offs; supports user intent to understand coverage metrics, choose appropriate testing methods, or justify structural testing adoption in CI/CD pipelines.
