Testing: The functions you wish existed

Write your test code with the functions/methods/classes you wish existed, not the ones you've been given. For example, don't write this:

self.driver.get(self.live_server_url + reverse("contact_form"))
self.driver.find_element_by_css_selector("#id_email").send_keys("[email protected]")
self.driver.find_element_by_css_selector("#id_message").send_keys("Hello")
self.driver.find_element_by_css_selector("input[type=submit]").click()
WebDriverWait(self.driver, 10).until(lambda driver: driver.find_element_by_css_selector("body"))

That looks very tedious! Write this instead:

self.get_url("contact_form")
self.fill({
    "#id_email": "[email protected]",
    "#id_message": "Hello",
})
self.submit("input[type=submit]")
