Unit Test Coverage
In Visual Studio:
Ctrl+Alt+K B
This window allows exploring coverage data obtained during unit tests coverage run.
Each snapshot can be presented in two views, which you can toggle with the buttons in the right of the toolbar:
Coverage Tree
In this view, all code items are grouped in a tree structure and you can study the coverage of each code item.
In the Coverage column, dotCover uses three colors to display the coverage status:
- Green - the percentage of covered statements within the node.
- Red - the percentage of uncovered statements within the node.
- Grey - the nodes not covered during the test run as they do not have executable code statements.
Hot Spots
In this view, you can quickly see the potential risk areas within the snapshot. To learn more, see Detecting Hot Spots.
