General Working PrinciplesTestwell CTC++ measures Code Coverage for desktop / host applications and for embedded software. It works in three fundamental steps: instrumenting, testing and reporting.
ReportingTestwell CTC++ provides a deeply structured HTML report, scalable to small and large projects. For data exchange, single-file text reports like XML or CSV can be generated.
The HTML ReportFor human readers, the HTML report is the standard report of Testwell CTC++. Here it is decribed how to read and interpret its information.
Source Code ViewEvery source code view page of the HTML report shows the source code of one file combined with coverage information for this file.

Source Code View

Every source code view page of the HTML report shows the source code of one file combined with coverage information for this file.

Details for the source file (expandable)
- Parent Entity: The entity hierarchically above this file in this report. If it is a directory, its name is potentially shortened.
- Source Code Location: The path and file name to the source code used for generating this report.
- Instrumentation Origin: Symbol files containing the current source file variant. If the file is included in other source files, these including files are also listed.
Counters are shown in two columns
- True: all true counters and also singular hit counters, e.g. for return statements.
- False: all false counters.
The source code from the file.
