Run/Debug Configuration: utest

IntelliJ IDEA lets you specify a Run/Debug configuration for utest.

The dialog consists of the following tabs:

Configuration tab
Code Coverage tab
Logs tab

Configuration tab

Item	Description
Test kind	From this list, select the scope for your tests and fill in the fields depending on your selection. You can choose from the following options: Test name - select this option to run the specified Scala test. The name of the test appears in the Test Name field. All in package - select this option to run all Scala tests in the specified package. Fill in the following fields: Test Package - specify the name of the package to be tested. Search for tests - use this list to select the scope of your search. Class - select this option to run all tests in a class. Specify the fully qualified name of the class to be launched in the Test Class field. Type the class name or click and select the desired class in the dialog that opens.
VM parameters	If necessary, specify the string to be passed to the VM. When specifying JVM options, follow these rules: Use spaces to separate individual options, for example, `-client -ea -Xmx1024m`. If an option includes spaces, enclose the spaces or the argument that contains spaces in double quotes, for example, `some" "arg` or `"some arg"`. If an option includes double quotes (as part of the argument), escape the double quotes using backslashes, for example, `-Dmy.prop=\"quoted_value\"`. You can pass environment variable values to custom Java properties. For example, if you define a variable `MY_ENV_VAR`, you can pass it to the `foo` property as follows: -Dfoo=${MY_ENV_VAR} If there is not enough space, you can click and enter the string in the dialog that opens.
Environment variables	Click to open the Environment Variables dialog where you can create variables and specify their values.
Test options	Use this field to specify the additional test options. If there is not enough space, you can click and enter the string in the dialog that opens.
Working Directory	Specify the directory that will act as the current directory when running the test. It will act as the root directory for all relative input and output paths. By default, the directory where the project file resides, is used as a working directory. Type directory name, or click and select the desired directory in the dialog that opens.
Use classpath and SDK of module	From this list, select the module whose classpath will be used to run the application.
Print information messages to console	Select this checkbox if you want to print information messages to the Scala console.

Code Coverage tab

Use this tab to configure code coverage monitoring options.

Item	Description
Choose coverage runner	Select the desired code coverage runner. By default, IntelliJ IDEA uses its own coverage engine with the Sampling mode. You can also choose JaCoCo for calculating coverage.
Sampling	Select this option to measure code coverage with minimal slow-down.
Tracing	Select this option to collect accurate branch coverage. This mode is available for the IntelliJ IDEA code coverage runner only.
Track per test coverage	Select this checkbox to detect lines covered by one test and all tests covering line. If this checkbox is selected, becomes available on the toolbar of the coverage statistic popup. This option is only available for the Tracing mode of code coverage measurement for the testing run/debug configurations. Refer to the section Set coverage in run configurations.
Packages and classes to record code coverage data	Click and select Add Class or Add Package to specify classes and packages to be measured. You can also remove classes and packages from the list by selecting them in the list and clicking the button.
Enable coverage in test folders	If this checkbox is selected, the folders marked as test are included in the code coverage analysis.

Logs tab

Use this tab to specify which log files generated while running or debugging should be displayed in the console, that is, on the dedicated tabs of the Run or Debug tool window.

Item	Description
Is Active	Select checkboxes in this column to have the log entries displayed in the corresponding tabs in the Run tool window or Debug tool window.
Log File Entry	The read-only fields in this column list the log files to show. The list can contain: Full paths to specific files. Ant patterns that define the range of files to be displayed. Aliases to substitute for full paths or patterns. These aliases are also displayed in the headers of the tabs where the corresponding log files are shown. If a log entry pattern defines more than one file, the tab header shows the name of the file instead of the log entry alias.
Skip Content	Select this checkbox to have the previous content of the selected log skipped.
Save console output to file	Select this checkbox to save the console output to the specified location. Type the path manually, or click the browse button and point to the desired location in the dialog that opens.
Show console when a message is printed to standard output stream	Select this checkbox to activate the output console and bring it forward if an associated process writes to Standard.out.
Show console when a message is printed to standard error stream	Select this checkbox to activate the output console and bring it forward if an associated process writes to Standard.err.
	Click this button to open the Edit Log Files Aliases dialog where you can select a new log entry and specify an alias for it.
	Click this button to edit the properties of the selected log file entry in the Edit Log Files Aliases dialog.
	Click this button to remove the selected log entry from the list.

Common settings

When you edit a run configuration (but not a run configuration template), you can specify the following options:


Name	Specify a name for the run configuration to quickly identify it among others when editing or running.
Allow multiple instances	Allow running multiple instances of this run configuration in parallel. By default, it is disabled, and when you start this configuration while another instance is still running, IntelliJ IDEA suggests stopping the running instance and starting another one. This is helpful when a run configuration consumes a lot of resources and there is no good reason to run multiple instances.
Store as project file	Save the file with the run configuration settings to share it with other team members. The default location is .idea/runConfigurations. However, if you do not want to share the .idea directory, you can save the configuration to any other directory within the project. By default, it is disabled, and IntelliJ IDEA stores run configuration settings in .idea/workspace.xml.
