Run/Debug Configuration: RSpec

Define the scope of tests to run:

• All specs in a folder: Select this option to run all tests in a particular directory.

• Spec script: Select this option to run a specific test.

• Multiple specs: Select this option to run tests from multiple spec files.

Specify the fully qualified path to the directory that contains the desired specs. Alternatively, click and select the specs directory in the dialog that opens.

This field is only available, when the All specs in folder option is selected.

Specify the mask of the spec file name, for example, **/*_spec.rb.

This field is only available, when the All specs in folder option is selected.

Specify the name of the script to be executed.

This field is only available, when the Spec script option is selected.

Specify the names of the desired specs. Alternatively, click and select the specs in the dialog that opens.

This field is only available, when the Multiple specs option is selected.

Specify one or several names of the examples within the script to be executed. Use || to separate example names.

If no example is specified, all examples will be executed.

This field is only available, if either the Spec script or Multiple specs option is selected.

From the list, select the server to be used for executing scripts or examples.
Select None if you want to execute a script or example locally, without any server.

Refer to for details.

Specify the list of environment variables as the name-value pairs, separated with semi-colons. Alternatively, click to create variables and specify their values in the Environment Variables dialog.

Specify the arguments to be passed to the Ruby interpreter.

Classpath property is added to Nailgun settings.

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.

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.

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.

Refer to the section Set coverage in run configurations.

This checkbox is only available for JRuby used as the project interpreter.

When a run/debug configuration, with this checkbox selected, is launched, IntelliJ IDEA analyzes the running processes, and does one of the following, depending on the presence of the running Nailgun server:

• If there is no running Nailgun server, or if there is a Nailgun server on a non-default port, or with a different gemset, then IntelliJ IDEA suggests to specify the desired port number.

• If a Nailgun server runs on the default port with the required gemset, IntelliJ IDEA does nothing.

• If a Nailgun server runs on a different port with the required gemset, then IntelliJ IDEA suggests to specify the desired port number.

• If a Nailgun server runs on the default port with a different gemset, then IntelliJ IDEA deletes the -ng argument.

If this checkbox is not selected, then the script is launched in a usual way, without Nailgun.

Name

Specify a name for the run/debug configuration to quickly identify it when editing or running the configuration, for example, from the Run popup Alt+Shift+F10.

Allow parallel run

Select to 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 to stop the running instance and start another one. This is helpful when a run/debug 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.

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 or and buttons.

To remove grouping, select a folder and click .

Click this icon to add one of the following available tasks:

• Run External tool: select to run an external application. In the dialog that opens, select one or multiple applications you want to run. If it is not defined in IntelliJ IDEA yet, add its definition. For more information, see External tools and External Tools.

• Run Another Configuration: select to execute another run/debug configuration. In the dialog that opens, select the configuration to be run.

• Build: select to compile the specified module. The Build Module command will be executed.

  If an error occurs during compilation, IntelliJ IDEA won't attempt to start the run/debug configuration.

• Build Project: select to compile the entire project. The Build Project command will be executed.

  If an error occurs during compilation, IntelliJ IDEA won't attempt to start the run/debug configuration.

• Build, no error check: the same as the Build option, but IntelliJ IDEA will try to start the run/debug configuration irrespective of the compilation results.

• Build Artifacts: select this option to build an artifact or artifacts. In the dialog that opens, select the artifact or artifacts that should be built.

• Launch Web Browser: select this option to have a browser started. In the dialog that opens, select the type of the browser and provide the start URL. Also, specify if you want the browser be launched with JavaScript debugger.

• Run Ant target: select this option to run an Ant target. In the dialog that opens, select the target to be run.

• Run Grunt task: select this option to run a Grunt task.

  In the Grunt task dialog that opens, specify the Gruntfile.js where the required task is defined, select the task to execute, and specify the arguments to pass to the Grunt tool.

  Specify the location of the Node.js interpreter, the parameters to pass to it, and the path to the grunt-cli package.

• Run Gulp task: select this option to run a Gulp task.

  In the Gulp task dialog that opens, specify the Gulpfile.js where the required task is defined, select the task to execute, and specify the arguments to pass to the Gulp tool.
