Run/Debug Configuration: JUnit Tests

JUnit run/debug configurations define how unit tests that are based on the JUnit testing framework should be run.

This run/debug configuration allows JUnit tests stored in MPS models to be run with JUnit.

Item

Description

Test scope

Click one of the radio-buttons to pick the granularity of the test to run - the whole project, a particular module, model, class or a method.

Project/Module/Model/
Classes/Methods

Specify the MPS project/module/model/classes/methods that holds the tests to run

Execute in the same process

Select this checkbox to indicate whether the tests should be run in the same MPS instance.
Onselect this checkbox to start a new invisible (headless) MPS process in the background to run the tests.
Running test in the same process is usually much faster.

Reuse caches

Indicates whether the generated artifacts, cached during the previous runs should be reused or deleted. Reusing the old caches of headless MPS instance when running tests cuts away a lot of time that would be needed to setup a test instance of MPS. It is possible to set and unset this option in the run configuration dialog.

Save caches in

Specify the directory to save the caches in. By default, MPS chooses the temp directory. Thus with the checkbox Reuse caches selected, MPS saves its caches in the specified folder and reuses them whenever possible. If this checkbox is unselected, the directory is cleared on every run.

VM parameters

Provide command-line arguments to the JVM

Program parameters

Provide command-line arguments to the class

Working directory

Override the default working directory with an explicit one

Use alternative JRE

Explicitly specify a JRE distribution to use for running the class

Common options

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

Item

Description

Name

In this field, specify the name for the run/debug configuration. The name will help you identify the created configuration when you choose to edit it later, or when you invoke it, for example, from the Run popup (Shift+Alt+F10).

Share

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

The shared run/debug configurations are kept in separate xml files under .idea \runConfigurations folder, while the local run/debug configurations are kept in the .idea\workspace.xml.

Allow running in parallel

When disabled, every time a new run/debug configuration is launched, MPS 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 selected, it is possible to launch as many instances of the run/debug configuration as required. So doing, each runner will start in its own tab of the Run Tool Window or Debug Tool Window.

Toolbar

The tree view of run/debug configurations has a toolbar that helps you manage configurations available in your project as well as adjust default configurations templates.

Item

Shortcut

Description

icons general add svgAlt+Insert

Create a run/debug configuration.

icons general remove svgAlt+Delete

Delete the selected run/debug configuration. Note that you cannot delete default configurations.

Copy

Ctrl+D

Create a copy of the selected run/debug configuration. Note that you create copies of default configurations.

Edi Templates

Edit Templates

View and edit the default template for the selected run/debug configuration. The templates are used for newly created configurations.

icons actions moveUp svg/icons actions moveDown svg

Alt+Up/Alt+Down

Move the selected run/debug configuration up and down in the list.

The order of configurations in the list defines the order, in which the configurations appear when you choose a run/debug configuration.

Default templates of run/debug configurations are always sorted alphabetically.

Move into new folder / Create new folder

Move into new folder / Create new folder

You can group run/debug configurations by placing them into folders.

To create a folder, select the configurations within a category, click Folder, and specify the folder name. If only a category is in focus, an empty folder is created.

Then, to move a configuration into a folder, between the folders or out of a folder, use drag-and-drop or Move Up and Move Down buttons.

To remove grouping, select a folder and click Remove Configuration.

Sort configurations

Sort configurations

Click this button to sort configurations in the alphabetical order.

Before Launch options

In this area you can specify tasks that must be performed before starting the selected run/debug configuration. The tasks are performed in the order they appear in the list.

Click these icons to move the selected task one line up or down in the list. (The tasks are performed in the order that they appear in the list.)

Show this page

Select this checkbox to show the run/debug configuration settings prior to actually starting the run/debug configuration.

Activate tool window

By default this checkbox is selected and the Run or the Debug tool window opens when you start the run/debug configuration.

Otherwise, if the checkbox is cleared, the tool window isn't shown. However, when the configuration is running, you can open the corresponding tool window for it yourself by pressing Alt+4 or Alt+5.
