Run/Debug Configuration: Karma

In this field, specify the command-line options that you want to pass to Karma to override the default settings from the karma.conf.js configuration file.

For example, to run or debug tests in Headless Chrome, type --browsers ChromeHeadless in the Karma options field. See Automated testing with Headless Chrome for details.

To see all the available CLI options, type karma start --help in the Terminal Alt+F12.

In this field, specify the Node.js interpreter to use. This can be a local Node.js interpreter or a Node.js on Windows Subsystem for Linux.

In this field, type the Node.js-specific command-line options to be passed to the Node.js executable file.

• Use --require coffeescript/register to have CoffeeScript files compiled into JavaScript on the fly during run.

  This mode requires that the register.js file, which is a part of the coffeescript package, is located inside your project. Therefore make sure you have the coffeescript package installed locally as described in Install the CoffeeScript compiler.

• Use --inspect or --inspect-brk parameter when you are using Node.js v7 for Chrome Debugging Protocol support. Otherwise, by default the debug process will use V8 Debugging Protocol.

In this field, specify the working directory of the application. By default, the Working directory field shows the project root folder. To change this predefined setting, specify the path to the desired folder or choose a previously used folder from the list.

In this area, specify the tests to be executed. The available options are:

• All tests: choose this option to run all the tests from the karma.conf.js configuration file.

• Test file: choose this option to run only the tests from one file and specify the path to this file in the Test file field.

• Suite: choose this option to run individual suites from a test file and specify the path to this file in the Test file field. Click in the Suite name field and configure a list of suites to run using the and buttons.

• Test: choose this option to run individual tests from a test file and specify the path to this file in the Test file field. Click in the Test name field and configure a list of tests to run using the and buttons.

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.

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 PyCharm 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 PyCharm yet, add its definition. For more information, see External tools and External Tools.

  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.

  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.

  In the NPM Script dialog that opens, specify the npm run/debug configuration settings.

• Compile TypeScript: select to run the built-in TypeScript compiler and thus make sure that all the changes you made to your TypeScript code are reflected in the generated JavaScript files. In the TypeScript Compile Settings dialog that opens, select or clear the Check errors checkbox to configure the behaviour of the compiler in case any errors are detected:

  • If the Check errors checkbox is selected, the compiler will show all the errors and the run configuration will not start.

  • If the Check errors checkbox is cleared, the compiler will show all the detected errors but the run configuration still will be launched.

• Generate CoffeeScript Source Maps: select this option to generate the source maps for your CoffeeScript sources. In the dialog that opens, specify where your CoffeeScript source files are located.

• Run Remote External tool: adds a remote SSH external tool.

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 is hidden. However, when the configuration is running, you can open the corresponding tool window for it yourself by pressing Alt+4 or Alt+5.
