Chapter 4: Errors in the test module

Trying to use the test module to test the results which I've got after completing Chapter 4.

The content of my about.html is the following:

<!DOCTYPE html>
<html>
     <head>
     </head>
     <body>
          <h1> About </h1>
          <img src="{{MEDIA_URL}}resin.jpg" alt="Галоша" />
          <p>
               This tutorial has been put together by Marshwiggle
          </p>
     </body>
</html>

So, when I start the module, I get a buch of errors:

Creating test database for alias 'default'...
System check identified no issues (0 silenced).

Destroying test database for alias 'default'...

I've tested my app in the browser and it seems to be working, so perhaps, there are some bugs in the tests.

For example, 'test_about_contains_create_message' method of the 'AboutPageTests' object is almost identical to the method with the same name in the Chapter4ViewTests object, but it raises no error, and that's because it has a type hint (i.e. "b" character) before the string in the last line.
