How To...?Depending on the customer specific environment, Testwell CTC++ is used for many different testing scenarios, in several build environments, IDEs and tool chains. In this section, generic instructions are found as well as specific instructions for these kind of third party software.
WorkflowsMeasuring Code Coverage with Testwell CTC++ always works in three independent steps: instrumentation - testing - report generation. Depending on the environment, different ways to use the components of Testwell CTC++ are advantageous. They are described in these chapters.
Test Runs with the Instrumented Program The instrumented program is tested without any change necessary. The coverage data is written out during the execution.
Appending vs. Overriding of Counter Data When a data file is reused in new tests, the counter data written out is added up to the existing counter data if the source file was not changed.

Appending vs. Overriding of Counter Data

When a data file is reused in new tests, the counter data written out is added up to the existing counter data if the source file was not changed.

The decision is made separately for each source file. In the data file, three scenarios are possible:

It does not contain coverage data for the source file. In this case, a new counter data block is written to the data file.
It does contain coverage data, but from different version of the source file. In this case, the counters in the data file are overwritten.
It does contain coverage data from the same version of the source file. In this case, the counters are added up.
