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 the NodeJS runtime environment that contains the Node Package Manager(npm).
- Using the Node Package Manager, install the Mocha test framework as described in Preparing to Use Mocha Test Framework.
Mocha-specific configuration settings
In this field,
specify the NodeJS installation home. Type the path to the NodeJS executable file manually,
or click the button
and select the location in the dialog box, that opens.
If you have appointed one of the installations as default, the field displays the path to its executable file.
|Node options||In this text box, type the NodeJS-specific command line options to be passed to the NodeJS executable file. See Node Parameters for details.|
In this field, specify the
working directory of the application.
All references in test scripts will be resolved relative to this folder, unless such references use full paths.
By default, the field shows the project root folder. To change this predefined setting, choose the desired folder from the drop-down list, or type the path manually, or click the Browse button and select the location in the dialog box, that opens.
In this field, specify the environment variables for the NodeJS executable file, if applicable.
Click the Browse button to the right of the field and configure a list of variables
in the Environment Variables dialog box, that opens:
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.|
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.|
|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.|
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.
