Python Testing 101 with Selenium
This document discusses different types of tests for web applications, including unit tests, functional tests, and integration tests. It provides examples of using Django and Selenium to write unit, functional, and integration tests. Unit tests test individual code units, functional tests test that code works together to produce the right results, and integration tests test that modules work together as a group. The document demonstrates writing tests to test views, models, and POST requests in Django.

- 1. Testing WebApps 101 Fornewbies by newbies
- 2. Requisites for thetalk ● Virtualenv (of course) ● Django ● Selenium
- 3. Different Types oftests ● Unit Tests A unit test establishes that the code does what you intended the code to do (e.g. you wanted to add parameter a and b, you in fact add them, and don't subtract them)
- 4. Different Types oftests ● Functional Tests Functional tests test that all of the code works together to get a correct result, so that what you intended the code to do in fact gets the right result in the system.
- 5. Different Types oftests ● Integration Tests Is the phase in software testing in which individual software modules are combined and tested as a group Integration tests tell what's not working. But they are of no use in guessing where the problem could be.
- 6. Some bugs aredependent of other modules
- 7. A single bugwill break several features, and several integration tests will fail
- 8. On the otherhand, the same bug will break just one unit test
