AdaTEST 95 code coverage capabilities can be used integrated with AdaTEST 95 tests, or with any external test driver.
It provides an objective measurement of test execution completeness, to supplement requirements based and robustness tests.
AdaTEST 95 code coverage makes it easy to:
Code Coverage is a dynamic analysis technique to measure which parts of the code have been executed by tests. The logic structure within the code can be identified by individual constructs (syntax elements). The measurement of these individual constructs is recorded using structural code coverage metrics.
Code coverage analysis is used to identify testing gaps where code is not exercised by requirements driven and robustness driven testing approaches.
Coverage analysis is required for compliance with all international software safety standards, with higher safety levels requiring achievement of more rigorous coverage metrics.

Code coverage is measured using the following metrics, with standard specific Rule Sets for integrated checking of required code coverage levels.
AdaTEST 95 diagnostics present code coverage data in an HTML Results Viewer featuring:
AdaTEST 95 code coverage checks integrated with tests, make enforcement of the required coverage easy and automatic for regression test runs. Coverage checks include:
In addition to the powerful diagnostics of code coverage results in the HTML Results Viewer and Overview, AdaTEST 95 generates safety standards certification ready ASCII text reports of compliance with coverage requirements.
Reports and certification evidence embed the integrated checks on the achievement of the required coverage metric targets.
AdaTEST 95 uses instrumentation on a copy of the source code, and coverage data is recorded for both HTML graphical diagnosis and certification ready ASCII text file evidence.
Coverage analysis can be used integrated with AdaTEST 95 tests or used to measure execution from other tests, and data from multiple tests can be easily combined.
Analysis is made simpler by coverage Rule Sets, which automate all the code instrumentation, data reporting and required coverage checking, for all the main software safety standards.
