Run/Debug Configuration: Scala
The dialog box consists of the following tabs:
|Main class||In this text box, specify the fully qualified name of the class to be executed (passed to the JRE). Type the class name manually or click the Browse button to open the Choose Main Class dialog box, where you can find the desired class by name or search through the project.|
|VM options||In this text box, specify the string to be passed to the VM for launching an application. Usually this string contains the options such as |
When specifying the options, follow these rules:
|Program arguments||In this text box, type a list of arguments to be passed to the program in the format you would use in the command line. If necessary, click the button and type the desired arguments in the Program Parameters dialog box. |
Use the same rules as for specifying the VM options.
|Working directory||In this text box, specify the current directory to be used by the running test. This directory is the starting point for all relative input and output paths. By default, the field contains the directory where the project file resides. To specify another directory, click the Browse button select the directory in the dialog that opens. |
Click this icon to view the list of available path variables that you can use as a path to your working directory.
|Environment variables||Click the Browse button to open the Environment Variables dialog box, where you can create variables and specify their values.|
|Use classpath of module||Select the module whose classpath should be used to run the application.|
|JRE||By default, the newest JDK from the module dependencies is used to run the application. If you want to specify an alternative JDK or JRE here, select it from the drop-down list.|
|Enable capturing form snapshots||Select this check box to enable the GUI Designer to take snapshots of the GUI components, that can be afterwards converted into a form.|
Code Coverage tab
Use this tab to configure code coverage monitoring options.
|Choose code coverage runner||Select the desired code coverage runner.|
|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 check box to detect lines covered by one test and all tests covering line. If this check box is selected, becomes available on the toolbar of the coverage statistic pop-up window. |
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.|
|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.|
|Enable coverage in test folders.||If this check box is selected, the folders marked as test are included in the code coverage analysis.|
|Is Active||Select check boxes 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: |
|Skip Content||Select this check box to have the previous content of the selected log skipped.|
|Save console output to file||Select this check box 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 check box 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 check box 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.|
|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.|
|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.|
|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.|
|Share|| Select this check box 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
If the file-based format is used, the settings are stored in the
This check box is not available when editing the run/debug configuration defaults.
|Single instance only||If this check box 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 check box 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.
|Before launch||Specify which tasks must be performed before applying the run/debug configuration. The specified tasks are performed in the order they appear in the list. |
