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.
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.
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.
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
Provide command-line arguments to the JVM
Provide command-line arguments to the class
Override the default working directory with an explicit one
Use alternative JRE
Explicitly specify a JRE distribution to use for running the class
When you edit a run configuration (but not a run configuration template), you can specify the following options for it:
In this text box, 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).
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.
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.
Create a run/debug configuration.
Delete the selected run/debug configuration. Note that you cannot delete default configurations.
Create a copy of the selected run/debug configuration. Note that you create copies of default configurations.
View and edit the default template for the selected run/debug configuration. The templates are used for newly created configurations.
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
You can group run/debug configurations by placing them into folders.
To create a folder, select the configurations within a category, click , 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 and buttons.
To remove grouping, select a folder and click .
Click this button to sort configurations in the alphabetical order.
Under the Templates node in the tree view of run configurations, you can select a run configuration template and edit its default settings. This will not affect the configurations that are already created, but will be used as defaults when creating new configurations of the corresponding type.
When you select the Templates node itself, you will be able to adjust general settings that apply to all run/debug configurations:
Configurations available in Run Dashboard
In this section you can create a list of run configurations available in the Run Dashboard — a tool window that helps you execute and manage multiple run/debug configurations.
Note that the dashboard will only display the configuration types for which you have created one ore more configurations.
Thus, if you add a configuration type for which no configurations exist in the project, this type will not be displayed on the dashboard until you create a configuration of this type.
Confirm rerun with process termination
|The behavior of this checkbox depends on whether the Single instance only option is selected for a particular run/debug configuration. |
Temporary configurations limit
Specify the maximum number of temporary configurations to be stored and shown in the Select Run/Debug Configuration drop-down list.
Before Launch options
In this area you can specify tasks that must be be performed before starting the selected run/debug configuration. The tasks are performed in the order they appear in the list.
Click this icon to add one of the following available tasks:
Click this icon to remove the selected task from the list.
Click this icon to edit the selected task. Make the necessary changes in the dialog that opens.
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
Otherwise, 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.
