dotCover 2021.1 Help

Unit Test Coverage

In Visual Studio:
ReSharper | Windows | Unit Test Coverage
Control+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.

Coverage Tree view in the Unit Test Coverage window

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 Detect Hot Spots.

The context menu in this window includes commands:

  • Exclude selected nodes

  • Exclude all nodes except selected

  • Exclude selected node and create coverage filter

These commands are rather self-explanatory; they allow excluding nodes from coverage snapshot presentation.
