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 Control+Alt+S to open the IDE settings and then select Plugins.
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.

JetBrains Rider: 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.

Toolbar Controls

Control	Name	Description
	All Tests	If selected, the tree shows aggregated coverage results from all unit test sessions.
	All Tests in Active Session	If selected, the tree shows coverage results for all unit tests from the session that is currently selected in the Unit Tests window.
	Selected Tests in Active Session	If selected, the tree shows coverage results for the test selected in the current session in the Unit Tests window.
	All Target Frameworks	Filters coverage results based on the selected target framework. This list is shown only if your project targets multiple frameworks.
	Highlight code	Toggles highlighting of the code in the editor for the current coverage snapshot. For more information, refer to dotCover documentation. If there are several snapshots that cover the same code, the highlighting shows results either of the last test session's snapshot or of the snapshot for which you last turned on the highlighting.
	Flatten Namespaces	Toggles between flat and tree namespace representation. In the flat mode, all namespaces including child namespaces are shown in a flat list (on the same level).
	Save coverage snapshot as	Saves the current snapshot to a .dcvr file. For more information, refer to https://www.jetbrains.com/help/dotcover/Saving_and_Loading_Coverage_Snapshot.html.
	Drop coverage results	Removes the existing coverage results. This command is available only when viewing coverage results of a particular unit test session.
	Export coverage reports	Allows you to export the test coverage report to one of the selected formats: HTML, JSON, XML, XML for NDepend.
	Navigate from Editor	Navigates you from a selected symbol in editor to this symbol in the coverage tree.
