Data Tables​

Test gaps​

io.moderne.prethink.table.TestGaps

Public non-trivial methods that have no test coverage, ranked by risk score.

Column NameDescription
Source pathThe path to the source file containing the untested method.
Class nameThe fully qualified name of the class.
Method nameThe simple name of the untested method.
Method signatureThe full method signature.
Cyclomatic complexityThe cyclomatic complexity of the untested method.
Risk scoreRisk score combining complexity and architectural centrality (call count). Higher = more critical gap.
Gap reasonWhy this gap matters, e.g., 'complexity 15, called by 8 methods, no test coverage'.
Suggested test classSuggested fully qualified name for the test class.
