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.
Choosing DetailsIn the menu in "Source & Details", you can choose different probe and counter information to be shown or hidden in the source code view.

Choosing Details

In the menu in "Source & Details", you can choose different probe and counter information to be shown or hidden in the source code view.

Single Probe Descriptions

Switched off by default, you can show also single probes (i.e., probes who are the only probe on their source code line) with their type and source code fragment recorded by ctc. This is useful for macro code, for example.

The counters move to the description line when switched on.

For lines with more than one probes, all probe descriptions are always shown with their counters on lines separated from the source code line.

Condition Blocks

The condition block is generated when condition coverage is one of the measures reported.

True-False-Tables

The true-false-tables are generated when multicondition coverage or MC/DC are reported. The MC/DC independence pairs refer to the evaluation alternatives.

MC/DC Blocks

This block is generated when MC/DC is reported.
