Does waiting for the parent tag ensures the complete loading of the child tag using Selenium?
A bit of more information would have helped us to construct a more canonical answer. However, just like each test is based on a unique test aim, the target element must also be unique for each test / test aim.
So, if your target element is the <div> your test should be based on the <div> as follows:
WebDriverWait(self.web_driver, WEB_DRIVER_WAIT_TIME).until( EC.presence_of_element_located((By.ID, "test")))Incase, your target element is the <h1> your test should be based on the <h1> as follows:
WebDriverWait(self.web_driver, WEB_DRIVER_WAIT_TIME).until( EC.presence_of_element_located((By.XPATH, "//div[@id='test']/h1[text()='Is this tag also loaded?']")))
