(iv) Action form, text box, check box, radio button

Automate interactions with various HTML controls with Webelement, such as entering text in a text box, clicking a button, selecting a Radio box or check box, getting text and property values for an element, and so on.

For example, the automation of the blog Park registration function:

(Here is just an example ha, the direct copy is useless, the following code only locates part of the field (mailbox, Login and Registration button), and does not process the verification code, the Verification Code section later to study how to deal with it)

1 defTest_register_new_user (self):2 3     #Locate and click on the Register of the blog Park homepage4 5Login_area = Self.driver.find_element_by_css_selector ('#login_area')6 7Register = Login_area.find_element_by_link_text ('Register')8 9 Register.click ()Ten  One     #Check open page title is not ' user Registration-blog Park ' A  -Self.asserttrue ('User Registration-Blog Park'==self.driver.title) -  the     #Locate registration page fields and register button -  -User_email = self.driver.find_element_by_id ('Email') -  +User_login_name = self.driver.find_element_by_id ('LoginName') -  +REGISTER_BTN = self.driver.find_element_by_id ('submitbtn') A  at     #Check that the maximum allowable input characters and minimum input characters in a field are the same as expected -  -Self.assertequal ('2', User_login_name.get_attribute ('Data-val-length-min')) -  -Self.assertequal (' -', User_login_name.get_attribute ('Data-val-length-max')) -  in     #check that each field and button are visible to the user and available -  toSelf.asserttrue (user_email.is_displayed () anduser_email.is_enabled ()) +  -     #Enter user Information the  *User_email.send_keys ('[email protected]') $ Panax NotoginsengUser_login_name.send_keys ('Test') -  the     #Click the Register button +  A Register_btn.click () the  +     #Check to see if a prompt for successful registration is displayed -  $Self.asserttrue (Self.driver.find_element_by_css_selector ('P.txt-title.success-color'). Text = ='Registration Successful')

For example, you can use the following method to check whether the check box for the blog Park login page is selected

1 defTest_login (self):2 3... Omit the code that opens the login page (this paragraph is not commented#)4 5Automatic_login = self.driver.find_element_by_id ('Remember_me')6 7     #Check the login page check box, whether it is not selected by default8 9 Self.assertfalse (automatic_login.is_selected ())Ten  One     #Click to select the check box A  -Automatic_login.click ()
