Python Global Name True Is Not Defined

Example of Error in Selenium Webdriver Generated Script

ERROR: test_registration (__main__.Registration)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "./Registration.py", line 17, in setUp
    self.accept_next_alert = true
NameError: global name 'true' is not defined

Cause

This is a syntax error. Boolean True and False are case-sensitive. Some older code may have them in lower case, which will cause an error in current versions of Python. For example:

    def setUp(self):
        self.driver = webdriver.Firefox()
        self.driver.implicitly_wait(30)
        self.base_url = "http://example.com"
        self.verificationErrors = []
        self.accept_next_alert = true
 

Solution

Capitalize the first letter of any boolean declarations.

        self.accept_next_alert = True
