Unit Tests Coverage window
Enable the dotCover plugin
This functionality relies on the dotCover plugin, which is bundled and enabled in JetBrains Rider by default. If the relevant features aren't available, make sure that you didn't disable the plugin.
Press Ctrl+Alt+S to open the IDE settings and then select .
Open the Installed tab, find the dotCover plugin, and select the checkbox next to the plugin name.
This window allows exploring coverage data obtained during unit tests coverage run. The window shows all code items from a coverage snapshot in a tree structure allowing you to inspect coverage of each 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.
