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.
Overview PageThe overview page of the HTML report (index.html) shows the coverage in total and per one or two levels of detail in a tabular view.
Sorting of the Data TableYou can sort the coverage data table in overview and detail pages by coverage ratio or by number of missing hits.

Sorting of the Data Table

You can sort the coverage data table in overview and detail pages by coverage ratio or by number of missing hits.

When generated, the entities in the table are ordered

alphabetically (directories and files),
as in their source file (functions).

For every measure column, the table can be sorted by coverage ratio or by number of missing hits. The second click reverts the order. The original sorting is reproduced in the first column.

When two levels of detail are shown in the table, the top level elements are sorted and for each top level element, its children are sorted by the same criterion.
