Run/Debug Configuration: Mocha
Getting access to the Run/Debug Configuration: Mocha dialog
- Install and enable the Node.js plugin. The plugin is not bundled with PyCharm, but it can be installed from the JetBrains plugin repository as described in Installing, Updating and Uninstalling Repository Plugins and Enabling and Disabling Plugins.
- Download and install Node.js that contains the Node Package Manager(npm).
- Using the Node Package Manager, install the Mocha test framework as described in Mocha.
Mocha-specific configuration settings
|Node.js interpreter|| In this field, specify the Node.js interpreter to use. Choose one of the configured interpreters or click and configure a new one as described in Configuring a local Node.js interpreter. If you choose the |
|Node options||In this text box, type the Node.js-specific command line options to be passed to the Node.js executable file. See Node Parameters for details.|
|Working directory|| 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.
|Environment variables|| In this field, specify the environment variables for the Node.js executable file, if applicable. Click Browse to the right of the field and configure a list of variables in the Environment Variables dialog box, that opens: |
The definitions of variables are displayed in the Environment variables read-only field with semicolons as separators. The acceptable variables are:
|Mocha package|| In this field, specify the Mocha installation home |
|User interface||From this drop-down list, choose the interface according to which the tests in the test folder are written. PyCharm will recognize only tests that comply with the chosen interface. If during test execution PyCharm runs against a test of another interface, the test session will be canceled with an error. This means that all the tests in the specified test folder must be written according to the same interface and this interface must be chosen from the drop-down list.|
|Extra Mocha options|| In this field, specify additional Mocha command line options. For example, add a |
|Tests|| In this area, specify the tests to be executed. The available options are: |
|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. |
The order of configurations or folders in the list defines the order in which configurations appear in the Run/Debug drop-down list on the main toolbar.
|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.|
|Share|| Select this check box to make the run/debug configuration available to other team members. |
The shared run/debug configurations are kept in separate xml files under
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, PyCharm 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. |
