Different outputs compared to test results in the documentation

[lilikppratama]

• HtmlTestRunner version: 1.2.1
• Python version: 3.7.7
• Operating System: Windows 10

I tried to reproduce the usage code from the documentation and here's the following result.

From what I've seen from the test results in the documentation and comparing my result

• Test class name in my result contain main
• Test class name in the documentation included in each test cases
• Tests with triple-quoted strings don't show up in my result

Is this issue related to Python version that I use? I want to remove the main string at the Test Class name in my result and show the triple-quoted strings instead so it'll be easier to read for stakeholders.
