Run/Debug Configuration: Utest

This feature is supported in the Ultimate edition only.

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

This section provides descriptions of the configuration-specific items, as well as the toolbar and options that are common for all run/debug configurations.

The dialog box consists of the following tabs:

Configuration tab

Item	Description
Test kind	From this drop-down 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 drop-down 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 the 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 the spaces in double quotes, for example, `some" "arg` or `"some arg"`. If an option includes double quotes (e.g. as part of the argument), escape the double quotes by means of the backslashes, for example, `-Dmy.prop=\"quoted_value\"`. 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 box 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 drop-down 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 code 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 or Emma 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 pop-up window. This option is only available for the Tracing mode of code coverage measurement for the testing run/debug configurations. Refer to the section Viewing Code Coverage Results.
Merge data with previous results	When you run your unit testing or application configuration several times, use this item to calculate statistics in the Project View, taking into account the statistics of each time you have run the configuration. Finally, the line is considered covered if it is covered at least once.
Packages and classes to record code coverage data	Click and buttons 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.
	Click this button to define the scope of code coverage analysis. In the Add Pattern dialog box that opens, type the comma-delimited list of Ruby regular expressions, and specify whether the matching files should be included into or excluded from code coverage analysis. The patterns defining files to be included into code coverage analysis, are marked with +; the ones to be excluded are marked with -. Each pattern can be enabled or disabled. To do that, select or clear the checkbox next to a pattern. By default, all newly created patterns are enabled.
	Click this button to delete the selected pattern from the list.
	Click this button to change the selected code coverage pattern.
Do not use the optimized C runtime	Select this checkbox to enable the option `--no-rcovrt`. Use this option with discretion, since it significantly slows down performance.
Enable coverage in test folders.	If this checkbox is selected, the folders marked as test are included in the code coverage analysis.

Use bundled coverage.py If this checkbox is selected, IntelliJ IDEA will use the bundled coverage.py.
If this checkbox is not selected, IntelliJ IDEA will use the coverage tool included in the selected Python interpreter.

Refer to the section Code Coverage for details.

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.
	Click this button to edit the select log file entry. The button is available only when an entry is selected.

Toolbar

Item	Shortcut	Description
	Alt+Insert	Click this button to add a new configuration to the list.
	Alt+Delete	Click this button to remove the selected configuration from the list.
	Ctrl+D	Click this button to create a copy of the selected configuration.
	Edit defaults	Click this button to edit the default configuration templates. The defaults are used for newly created configurations.
or	Alt+Up or Alt+Down	Use these buttons to move the selected configuration or folder up and down in the list. The order of configurations or folders in the list defines the order in which configurations appear in the Run/Debug drop-down list on the main toolbar.
	Move into new folder / Create new folder	Use this button to create a new folder. If one or more run/debug configurations are in focus, the selected run/debug configurations are automatically moved to the newly created folder. If only a category is in focus, an empty folder is created. Move run/debug configurations to a folder using drag-and-drop, or the buttons.
	Sort configurations	Click this button to sort configurations in alphabetical order.

Common options

Item Description

Name In this text box, specify the name of the current run/debug configuration. This field does not appear for the default run/debug configurations.

Defaults This node in the left-hand pane of the dialog box contains the default run/debug configuration settings. Select the desired configuration to change its default settings in the right-hand pane. The defaults are applied to all newly created run/debug configurations.

Select this checkbox to make the run/debug configuration available to other team members.

If the directory-based project format is used, the settings for a run/debug configuration are stored in a separate .xml file in the .idea\runConfigurations folder if the run/debug configuration is shared, or in the .idea\workspace.xml file otherwise.

If the file-based format is used, the settings are stored in the .ipr file for shared configurations, or in the .iws file otherwise.

This checkbox is not available when editing the run/debug configuration defaults.

Single instance only

If this checkbox is selected, this run/debug configuration cannot be launched more than once.

Every time a new run/debug configuration is launched, IntelliJ IDEA checks the presence of the other instances of the same run/debug configuration, and displays a confirmation dialog box. If you click OK in the confirmation dialog box, the first instance of the runner will be stopped, and the next one will take its place.

This makes sense when the usage of certain resources can cause conflicts, or when launching two run/debug configurations of the same type consumes too much of the CPU and memory resources.

If this checkbox is not selected, it is possible to launch as many instances of the runner as required. So doing, each runner will start in its own tab of the Run tool window.
