How to execute methods in a class using Selenium and Python

Question

I recently found the SeleniumIDE extension for Google Chrome, but there is something I don't understand...

from selenium import webdriver
from selenium.webdriver.common.by import By

class TestStealth():
 def setup_method(self, method):
 print("setup_method")
 self.driver = webdriver.Chrome()
 self.vars = {}

def teardown_method(self, method):
 self.driver.quit()

def test_stealth(self):
 print("Testing")
 self.driver.get("https://stealthxio.myshopify.com/products/stealthxio-practice")
 self.driver.set_window_size(968, 1039)

this is the code I get from selenium, when I try to run with:

run = TestStealth()
run.setup_method()
run.test_stealth()

I get an error in run.setup_method() as:

Missing 1 required positional argument: 'method'

Does anyone know what I am doing wrong?

What do you not understand? The error is telling you exactly what is wrong, you are missing a required argument, method. Note, you don't do anything with that, so it seems you should just omit that from the definition — juanpa.arrivillaga

This error message...

Missing 1 required positional argument: 'method'

...implies that the setup_method() is missing a required positional argument, i.e. 'method'

Analysis

You were pretty close. As per the defination of setup_method(self, method) it expects an argument as method.

def setup_method(self, method):

But when you invoked setup_method() as in:

run.setup_method()

You haven't passed any argument. Hence there was a argument mismatch and you see the error.

Solution

To execute your tests with in the Class using Selenium you can use the following solution:

Code Block:

class TestStealth():
    def setup_method(self):
        print("setup_method")
        self.driver = webdriver.Chrome(executable_path=r'C:\WebDrivers\chromedriver.exe')
        self.vars = {}

    def teardown_method(self):
       self.driver.quit()

    def test_stealth(self):
       print("Testing")
       self.driver.get("https://stealthxio.myshopify.com/products/stealthxio-practice")
       self.driver.set_window_size(968, 1039)    

run = TestStealth()
run.setup_method()
run.test_stealth()

Console Output:

setup_method

You mean that the "method" argument is useless?
