Default Plugins

This document contains a list of plugins that are available per default when using tricot.

CleanupPlugin

The CleanupPlugin can be used to remove files and directories that have been created during tests. Relative paths are resolved to the directory the plugin is defined in. Non empty directories are only cleaned up when the force key was set to True.

Type Validation:

param_type = dict
inner_types = {
                'force': {'required': False, 'type': bool},
                'items': {'required': True, 'type': list}
              }

Example:

plugins:
    - cleanup:
        force: false
        items:
            - /tmp/test
            - /tmp/test2

CleanupCommandPlugin

The CleanupCommandPlugin can be used to launch os-commands at the end of a tester. It is intended to be used for more complicated cleanup actions, that cannot be performed by the CleanupPlugin.

Type Validation:

param_type = dict
inner_types = {
                'shell': {'required': False, 'type': bool},
                'ignore_error': {'required': False, 'type': bool},
                'timeout': {'required': False, 'type': int},
                'cmd': {'required': True, 'type': list}
              }

Example:

plugins:
    - cleanup_command:
        ignore_error: True
        cmd:
            - rm
            - -rf
            - /tmp/leftover

CopyPlugin

The CopyPlugin can be used to copy files and directories before a test runs. It also offers a cleanup action to remove copied files after the test. File to copy are specified within the from list and their destination is the corresponding index in the to list.

Type Validation:

param_type = dict
inner_types = {
                'cleanup': {'required': False, 'type': bool},
                'from': {'required': True, 'type': list},
                'to': {'required': True, 'type': list}
              }

Example:

plugins:
    - copy:
        cleanup: True
        recursive: False
        from:
            - /tmp/from-here
            - /tmp/and-here
        to:
            - /opt/to-there
            - /home/user/and-there

HttpListenerPlugin

The HttpListenerPlugin starts a HTTP server in the background and servers files from the user specified directory. Relative paths are resolved to the directory where the plugin is defined in.

Type Validation:

param_type = dict
inner_types = {
                'port': {'required': True, 'type': int},
                'dir': {'required': True, 'type': str}
              }

Example:

plugins:
    - http_listener:
        port: 8000
        dir: ./www

MkdirPlugin

The MkdirPlugin simply creates the user specified directories. Relative paths are interpreted to the directory the plugin was configured in. Created directories can be cleaned up after the test by using the cleanup key. By default, this only removes empty directories. If you want to remove directories with content, you have to set the force key to True.

Type Validation:

param_type = dict
inner_types = {
                'cleanup': {'required': False, 'type': bool},
                'force': {'required': False, 'type': bool},
                'dirs': {'required': True, 'type': list}
              }

Example:

plugins:
    - mkdir:
        cleanup: true
        force: false
        dirs:
            - /tmp/test
            - /tmp/test2

OsCommandPlugin

The OsCommandPlugin simply executes the specified operating system command. Commands are executed from the directory where the plugin was configured in. The plugin allows some additional configuration by using different plugin keys:

  • background: Execute the command in the background.
  • ignore_error: decides whether a failed command execution leads to a plugin error. Default is False.
  • init: Sleep the specified amount of seconds before going on with the test. Command is executed in the background. This gives the command some initialization time.
  • timeout: Timeout the command after the specified amount of seconds. A timed out plugin will cause an error. Use init if you need a timeout without error.
  • shell: Execute the command in shell mode.

Type Validation:

param_type = dict
inner_types = {
                'shell': {'required': False, 'type': bool},
                'ignore_error': {'required': False, 'type': bool},
                'init': {'required': False, 'type': int},
                'background': {'required': False, 'type': bool},
                'timeout': {'required': False, 'type': int},
                'cmd': {'required': True, 'type': list}
              }

Example:

plugins:
    - os_command:
        init: 1
        cmd:
            - nc
            - -vlp
            - 4444

TempFilePlugin

The TempFilePlugin allows the creation of temporary files. The path for the temporary file is the only required parameter. The content of the file and the creation mode can optionally be specified.

Type Validation:

param_type = dict
inner_types = {
                'path': {'required': True, 'type': str},
                'content': {'required': False, 'type': str},
                'mode': {'required': False, 'type': str}
              }

Example:

plugins:
    - tempfile:
        path: /tmp/tricot_tempfile
        content: |-
            This is some content for the tempfile
