Requirements Coverage as an Adequacy Measure for Conformance Testing

Conformance testing in model-based development refers to the testing activity that verifies whether the code generated (manually or automatically) from the model is behaviorally equivalent to the model. Presently the adequacy of conformance testing is inferred by measuring structural coverage achieved over the model. We hypothesize that adequacy metrics for conformance testing should consider structural coverage over the requirements either in place of or in addition to structural coverage over the model.

Partial Translation Verification for Untrusted Code-Generators

Within the context of model-based development, the correctness of code generators for modeling notations such as Simulink and Stateflow is of obvious importance. If correctness of code generation can be shown, the extensive and often costly verification and validation activities conducted in the modeling domain could be effectively leveraged in the code domain. Unfortunately, most code generators in use today give no guarantees of correctness.

ReqsCov: A Tool for Measuring Test-Adequacy over Requirements

When creating test cases for software, a common approach is to create tests that exercise requirements. Determining the adequacy of test cases, however, is generally done through inspection or indirectly by measuring structural coverage of an executable artifact (such as source code or a software model). We present ReqsCov, a tool to directly measure requirements coverage provided by test cases.
