Run/Debug Configuration: Nosetests

Last modified: 28 June 2021

warning

The following is only valid when the Python plugin is installed and enabled.

Use this dialog box to create a run/debug configuration for Nose tests.

Configuration tab

ItemDescription
Nosetests
Target: Module name/Script path/Custom

Click one of the radio-buttons to choose the possible target.:

  • Module name: by using a Python module name and a test class instance.

  • Script path: by using a path to a Python file.

  • Custom: by using an arbitrary combination of paths, modules, and test class instances.

Depending on the selected Target type, you can specify the following values:

  • Path to the test file, for example, /Users/jetbrains/Car/my_tests/test_car.py. You can type in the path or click the Browse button to locate the file in the project structure.

  • Name of the module in your project, for example, my_tests. You can type in the module name, search the target module by its name, or locate it in the project structure.

  • Custom combination of modules, scripts, classes, and methods, for example, my_tests.test_car.TestCar.test_brake, where:

    • my_tests: the module name

    • test_car: the target file in the module

    • TestCar: the class instance in test_car

    • test_brake: the method in the TestCar class

Regex PatternIn this text field, specify the regex pattern that describes all the test in the required location. Files, directories, function names, and class names that match the specified regex pattern, are considered tests, for example test.*
Additional Arguments

In this text field, specify the additional framework-specific arguments to be passed to the test as-is, for example
--some-argument=some-value.

warning

This option is not recommended and should only be used by the experts, who want to launch something not supported by IntelliJ IDEA.

Environment variableClick the browse button, or press Shift+Enter to specify the desired set of environment variables in the Environment Variables dialog box. To create a new variable, click Icons general add, and type the desired name and value.
Python Interpreter
Interpreter optionsIn this field, specify the command-line options to be passed to the interpreter. If necessary, click Expand the field, and type the string in the editor.
Working directory

Specify a directory to be used by the running task.

  • When a default run/debug configuration is created by the keyboard shortcut Ctrl+Shift+F10, or by choosing Run from the context menu of a script, the working directory is the one that contains the executable script. This directory may differ from the project directory.

  • When this field is left blank, the bin directory of the IntelliJ IDEA installation will be used.

Path mappingsThis field appears, if a remote interpreter has been selected in the field Python interpreter.
Click the browse button the Browse button to define the required mappings between the local and remote paths. In the Edit Path Mappings dialog, use the Add button/ the Remove button buttons to create new mappings, or delete the selected ones.
Add content roots to PYTHONPATHSelect this checkbox to add all content roots of your project to the environment variable PYTHONPATH;
Add source roots to PYTHONPATHSelect this checkbox to add all source roots of your project to the environment variable PYTHONPATH;
Docker container settings

warning

This field only appears when a Docker-based remote interpreter is selected for a project..

note

Speaking about the correspondence of settings with some options (--net, --link, and so on), note that these options come from Docker command line arguments.

Click the Browse button to open the dialog and specify the following settings:

Options

  • Disable networking: select this checkbox to have the networking disabled. This corresponds to --net="none", which means that inside a container the external network resources are not available.

  • Network mode: corresponds to the other values of the option --net.

    • bridge is the default value. An IP address will be allocated for container on the bridge’s network and traffic will be routed through this bridge to the container.
      Containers can communicate via their IP addresses by default. To communicate by name, they must be linked.

    • host: use the host's network stack inside the container.

    • container:<name|id>: use the network stack of another container, specified via its name or id.

    Refer to the Network settings documentation for details.

  • Links: Use this section to link the container to be created with the other containers. This is applicable to Network mode = bridge and corresponds to the --link option.

  • Publish all ports: Expose all container ports to the host. This corresponds to the option --publish-all.

  • Port bindings: Specify the list of port bindings. Similar to using the -p option with docker run.

  • Extra hosts: This corresponds to the --add-host option. Refer to the page Managing /etc/hosts for details.

  • Volume bindings: Use this field to specify the bindings between the special folders- volumes and the folders of the computer, where the Docker daemon runs. This corresponds to the -v option.
    See Managing data in containers for details.

  • Environment variables: Use this field to specify the list of environment variables and their values. This corresponds to the -e option. Refer to the page ENV (environment variables) for details.

Click Icons actions move down to expand the tables. Click Icons general add, Icons general remove, or Icons actions edit to make up the lists.

Logs tab

Use this tab to specify which log files generated while running or debugging should be displayed in the console, that is, on the dedicated tabs of the Run or Debug tool window.

ItemDescription
Is ActiveSelect checkboxes 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:

  • 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.

Skip ContentSelect this checkbox to have the previous content of the selected log skipped.
Save console output to fileSelect this checkbox 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 streamSelect this checkbox 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 streamSelect this checkbox to activate the output console and bring it forward if an associated process writes to Standard.err.
the Add buttonClick this button to open the Edit Log Files Aliases dialog where you can select a new log entry and specify an alias for it.
the Edit buttonClick this button to edit the properties of the selected log file entry in the Edit Log Files Aliases dialog.
the Delete buttonClick this button to remove the selected log entry from the list.

Common

When you edit a run configuration (but not a run configuration template), you can specify the following options:

Item

Description

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.

Toolbar

The tree view of run/debug configurations has a toolbar that helps you manage configurations available in your project as well as adjust default configurations templates.

ItemShortcutDescription
the Add buttonAlt+InsertCreate a run/debug configuration.
the Remove buttonAlt+DeleteDelete the selected run/debug configuration. Note that you cannot delete default configurations.
CopyCtrl+DCreate a copy of the selected run/debug configuration. Note that you create copies of default configurations.
Save configurationThe button is displayed only when you select a temporary configuration. Click this button to save a temporary configuration as permanent.
Edit TemplatesView and edit the template (that is, the default run/debug configuration settings). The templates are displayed under the Templates node and used for newly created configurations.
Method up/ Method downAlt+Up/ Alt+Down

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

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 Folder, 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 Move Up and Move Down buttons.

To remove grouping, select a folder and click Remove Configuration.

Sort configurations Click this button to sort configurations in the alphabetical order.

Before Launch

In this area, you can specify tasks to be performed before starting the selected run/debug configuration. The tasks are performed in the order they appear in the list.

ItemShortcutDescription
