What does if __name__ == "__main__": do?

You can disable it by setting sortTestMethodsUsing to None:

import unittest
unittest.TestLoader.sortTestMethodsUsing = None

For pure unit tests, you folks are right; but for component tests and integration tests... I do not agree that you shall assume nothing about the state. What if you are testing the state?

For example, your test validates that a service is auto-started upon installation. If in your setup, you start the service, then do the assertion, and then you are no longer testing the state, but you are testing the "service start" functionality.

Another example is when your setup takes a long time or requires a lot of space and it just becomes impractical to run the setup frequently.

Many developers tend to use "unit test" frameworks for component testing...so stop and ask yourself, am I doing unit testing or component testing?

The Perfect Way for Test Automation Maintenance

Without a doubt, automated browser testing has transformed the way software development works. If it wasn’t for Selenium, we wouldn’t be able to use such a wide array of bug-free web apps as we do. But sometimes, even the IT sector misunderstands the term automation.

Handling Multiple Browser Tabs With Selenium Automation Testing

Automation testing with Selenium has been a lifeline in grooming budding automation testers into professionals. Selenium being open-source is largely adopted on a global scale. As a result of which you get huge support from the community. There are multiple frameworks for different languages that offer bindings with Selenium. So you have got everything on board for getting started with Selenium. Now, comes the phases where you run your first test script to perform Selenium. The scripts would involve basic test scenarios if you are learning Selenium automation. You may validate:
