  """
  The BaseCase class is the main gateway for using The SeleniumBase Framework.
  It inherits Python's unittest.TestCase class, and runs with Pytest or Nose.
  All tests using BaseCase automatically launch WebDriver browsers for tests.
  
  Usage:
  
      from seleniumbase import BaseCase
      class MyTestClass(BaseCase):
          def test_anything(self):
              # Write your code here. Example:
              self.open("https://github.com/")
              self.update_text("input.header-search-input", "SeleniumBase\n")
              self.click('a[href="/seleniumbase/SeleniumBase"]')
              self.assert_element("div.repository-content")
              ....
  
  SeleniumBase methods expand and improve on existing WebDriver commands.
  Improvements include making WebDriver more robust, reliable, and flexible.
  Page elements are given enough time to load before WebDriver acts on them.
  Code becomes greatly simplified and easier to maintain.

      def check_window(self, name="default", level=0, baseline=False):
          """ ***  Automated Visual Testing with SeleniumBase  ***
  
              The first time a test calls self.check_window() for a unique "name"
              parameter provided, it will set a visual baseline, meaning that it
              creates a folder, saves the URL to a file, saves the current window
              screenshot to a file, and creates the following three files
              with the listed data saved:
              tags_level1.txt  ->  HTML tags from the window
              tags_level2.txt  ->  HTML tags + attributes from the window
              tags_level3.txt  ->  HTML tags + attributes/values from the window
  
              Baseline folders are named based on the test name and the name
              parameter passed to self.check_window(). The same test can store
              multiple baseline folders.
  
              If the baseline is being set/reset, the "level" doesn't matter.
  
              After the first run of self.check_window(), it will compare the
              HTML tags of the latest window to the one from the initial run.
              Here's how the level system works:
              * level=0 ->
                  DRY RUN ONLY - Will perform a comparison to the baseline, and
                                 print out any differences that are found, but
                                 won't fail the test even if differences exist.
              * level=1 ->
                  HTML tags are compared to tags_level1.txt
              * level=2 ->
                  HTML tags are compared to tags_level1.txt and
                  HTML tags/attributes are compared to tags_level2.txt
              * level=3 ->
                  HTML tags are compared to tags_level1.txt and
                  HTML tags + attributes are compared to tags_level2.txt and
                  HTML tags + attributes/values are compared to tags_level3.txt
              As shown, Level-3 is the most strict, Level-1 is the least strict.
              If the comparisons from the latest window to the existing baseline
              don't match, the current test will fail, except for Level-0 tests.
  
              You can reset the visual baseline on the command line by using:
                  --visual_baseline
              As long as "--visual_baseline" is used on the command line while
              running tests, the self.check_window() method cannot fail because
              it will rebuild the visual baseline rather than comparing the html
              tags of the latest run to the existing baseline. If there are any
              expected layout changes to a website that you're testing, you'll
              need to reset the baseline to prevent unnecessary failures.
  
              self.check_window() will fail with "Page Domain Mismatch Failure"
              if the page domain doesn't match the domain of the baseline.
  
              If you want to use self.check_window() to compare a web page to
              a later version of itself from within the same test run, you can
              add the parameter "baseline=True" to the first time you call
              self.check_window() in a test to use that as the baseline. This
              only makes sense if you're calling self.check_window() more than
              once with the same name parameter in the same test.
  
              Automated Visual Testing with self.check_window() is not very
              effective for websites that have dynamic content that changes
              the layout and structure of web pages. For those, you're much
              better off using regular SeleniumBase functional testing.
  
              Example usage:
                  self.check_window(name="testing", level=0)
                  self.check_window(name="xkcd_home", level=1)
                  self.check_window(name="github_page", level=2)
