What is unitTest?
The word “Unit” means break the whole testing suite into testing cases. If we apply it to Web automation, then you will have a testing suite which includes many unit testing scenario. For example –
- Login
- Update profile
- Logout
- ….
For the selenium/python, we will need unitTest framework to help us to manage these unit testing scenario, execution, verify or assert testing results.
In addition, we may also prepare the testing data or configuration before each unit testing scenario and reset the environment or configuration at the end of each unit testing cases. that’s why we need unitTesting framework here.
