Custom library doesn't exist-CodePudding

I am getting started with robot framework using python. I have following folder structure:

Tests have .robot files and Library has .py files.

This is what my robot file looks like

*** Settings ***
Library   /Library/CustomLib.py

*** Test Cases ***

Testing
    ${name}     generate random name    ${10}
    log to console ${name}

This is what my CustomLib.py file has:

import random
import string


__version__ = '1.0.0'

from robot.api.deco import keyword


class CustomLib:
  ROBOT_LIBRARY_VERSION = __version__
  ROBOT_LIBRARY_SCOPE = 'GLOBAL'

  @keyword('generate random name')
  def get_random_name(self, email_length):
      letters = string.ascii_lowercase[:12]
      return ''.join(random.choice(letters) for i in range(email_length))

At runtime it throws error that file doesn't exist and "No keyword with name 'Generate random name' found."

Though when I cmd click on this keyword it takes me to the exact same method. I know it's some simple little thing but can't seem to figure out what.

Change your library import path. If import the library this way you shouldnt have problems regardless of the directory where you are calling the robot cmd from.

Library    ${CURDIR}${/}..${/}Library${/}CustomLib.py

the CURDIR variable is

An absolute path to the directory where the test data file is located. This variable is case-sensitive.

CodePudding user response：

The error is because of how you defined the path to the library during its import - you've prefixed it with /, which means absolute path, e.g. "look for the directory Library from the root of the file system".

Just use a relative import, and you should be fine; if your tests are in the folder Tests, change the import to:

*** Settings ***
Library  ../Library/CustomLib.py

If they are in Tests/FunctionalityX/Another, then it would be like this, and so on:

*** Settings ***
Library  ../../../Library/CustomLib.py
