Overview

There are two workflows, with and without the coverage agent REST client, that enable you to generate a local coverage report and upload the results to DTP.

You can leverage the capabilities of the coverage_wizard.exe tool to collect coverage for .NET web applications by providing the entry point of the application under test and the path to dotnet.exe; see Configuring the Coverage Wizard for details.

Note: In typical workflows, dotTEST collects coverage for web applications deployed on IIS server.

dotTEST ships with the coverage_wizard.exe tool that facilitates collecting coverage information from managed code during execution of standalone applications. Running coverage_wizard.exe launches a wizard that allows you to specify the necessary information in the GUI. Alternatively, you can provide the information with the dedicated command line options.

Configuring the Coverage Wizard

Run the <INSTALL_DIR>\coverage_wizard.exe tool and specify the following information:
- Full path to the application
- Command line arguments
- Working directory
- Full path to engine directory
Complete the Full path to the application field with the path to dotnet.exe and the Command line arguments field with the entry point of the application. For example:
Specify the .NET CLR version used by the application.
Specify a directory where the scripts generated by the wizard will be saved.
Specify if you want to collect coverage information with or without the coverage agent REST client:
- If you enable the Use Coverage Agent option, enable or disable the Collect coverage without admin privileges option (see Collecting Coverage without Admin Privileges), then skip steps 5-7 and click Finish.
- If you enable the Without Coverage Agent option (default), proceed to steps 5-7.
Define the scope of coverage to import by providing -solution or -project switches that will be passed to the dotTEST executable so that it can locate sources. See Configuring the Test Scope for more information about the switches.
Enable or disable the Remove old coverage data before each run option. This option is enabled by default.
By default, runtime coverage information that was collected during previous executions is deleted. Disabling this option will prevent removing the data from previous runs.
Enable or disable the Run application immediately option to automatically launch the monitorCoverage.bat script ( if enabled, the application must be manually launched with the script generated by the wizard in the location specified in step 3).

Using the Command Line Options

You can run coverage_wizard.exe with the dedicated command line options to specify the information necessary for collecting application coverage:

coverage_wizard.exe -app [path] -workingDir [path] -appArgs [arguments] -commandsDir [path] -scope [dotTEST scope switch] -clr [version] -run

The following options are available:

Option Name	Value	Description
`-app`	`[path]`	Specifies the full path to the application.
`-workingDir`	`[path]`	Specifies the path to the working directory.
`-appArgs`	`[argument]`	Specifies the application command line arguments.
`-commandsDir`	`[path]`	Specifies the directory for the *.bat scripts generated by the coverage tool.
`-scope`	`-solution [path]` `-project [path]`	Specifies the scope of the coverage to import by providing `-solution` or `-project` switches that will be passed to dotTEST executable so that it can locate sources. For example: `-scope "-solution C:\temp\Scope.sln"` `-scope "-project C:\temp\Scope.csproj"` See Configuring the Test Scope for more information about the switches.
`-clr`	`v20` `v40`	Specifies the .NET CLR version used by the application;
`-run`	`none`	Automatically launches the `monitorCoverage.bat` script (optional; you can also open the directory specified with the `-commandDir` option and manually run the script).
`-doNotRemoveOldCoverage`	`none`	Specifies that old coverage data is not deleted before each run. If this option is not specified, coverage data collected during previous runs is deleted by default.
`-withCoverageAgent`	`none`	Specifies that coverage is collected with the coverage agent.

Collecting Coverage without Coverage Agent REST Client

If you configure the coverage wizard to run without the coverage agent REST client, the tool creates the following scripts in the directory specified as the Target scripts directory (see Configuring the Coverage Wizard):

monitorCoverage.bat runs and monitors the application
importCoverage.bat imports and reports coverage data

Run the monitorCoverage.bat script (skip this step if you launched the coverage wizard with the Run application immediately option enabled). This will run the specified application.
Interact with the application and perform your tests.
Close the application.
Run the importCoverage.bat script to generate the report in the following location: [Target scripts directory]\reports.
View the coverage information.

Collecting Coverage with Coverage Agent REST Client

If you configure the coverage wizard to run with the coverage agent REST client, the tool creates the following scripts in the directory specified as the Target scripts directory (see Configuring the Coverage Wizard):

monitorCoverage.bat runs and monitors the application
runCamAgent.bat runs the coverage agent

To collect application coverage with the coverage agent:

Generate the static coverage file with source code information; see Generating the Static Coverage File with Source Code Information.
Run the runCamAgent.bat script to launch the coverage agent.
Run the monitorCoverage.bat script to launch the application.
Perform the testing.
Download runtime coverage and test results.
Close the application.

By default, the coverage agent is available via the HTTP protocol. If you want to connect via HTTPS, open the runCamAgent.bat script before you run it and modify the command line for running the Agent Client tool to pass the information about an SSL certificate, for example:

"<INSTALL_DIR>\integration\coverage\agent\agent_client.exe" -standalone -port 8050
-useSsl -certificateHash <SSL certificate hash>

See Connecting with the Coverage Agent via HTTPS and Agent Client Options for details about configuring an SSL certificate for the coverage agent and a list of available options.

Collecting Coverage without Admin Privileges

By default, dotTEST requires admin privileges to collect coverage with coverage agent REST client, but you can configure the tool to collect coverage by users without admin privileges.

Enable the Collect coverage without admin privileges option (see Configuring the Coverage Wizard) and launch the wizard. As a result, two additional .bat scripts will be generated:
- runCamAgentInit.bat
- runCamAgentUninit.bat
Run the runCamAgentInit.bat script with admin privileges to setup and initialize the coverage agent. This will enable the users without admin privileges to perform the testing, as described in Collecting Coverage with Coverage Agent REST Client.
When testing is completed, run the runCamAgentUninit.bat script to stop the process
