What is Selenium?
Selenium is a chemical element with symbol Se and atomic number 34. It is a nonmetal with properties that are intermediate between those of its periodic table column-adjacent chalcogen elements sulfur and tellurium. It rarely occurs in its elemental state in nature, or as pure ore compounds. Selenium (Greek σελήνη selene meaning "Moon") was discovered in 1817 by Jöns Jacob Berzelius, who noted the similarity of the new element to the previously known tellurium (named for the Earth).
Selenium - PyTest
Browser Automation and testing in Python
Created by Jonathan Garza
What is SeleniumHQ?
Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.
Selenium has the support of some of the largest browser vendors who have taken (or are taking) steps to make Selenium a native part of their browser. It is also the core technology in countless other browser automation tools, APIs and frameworks.
Let's see Selenium in action
Unit Tests vs Functional Tests
Let’s review. There are basically 2 kinds of automated tests: Unit and Functional.
Unit Tests
Unit tests are written from the developer’s perspective, and typically target a method or a class (did my sort method sort properly?).
Functional Tests
Functional tests (sometimes referred to as Integration tests by who prefer the extra syllable) are written from the user’s perspective, and usually test the interaction between multiple building blocks of the application (is the user able to log in? Can she update her account?).
"Unit testing makes sure you are using quality ingredients. Functional testing makes sure your application doesn't taste like crap." - Brett Jones
Let's see Selenium with PyPE
Testing considerations with UTDirect
"Please ensure that when you write your load testing scripts that you cache the authentication session information of your user(s). The goal of your load testing should be to test your application, not UTLogin." -Dustin Slater
- Mock with PyPE app can fake UTDirect login process
- PyTest fixtures
PyTest
Helps you write better programs
- No boilerplate code
- test discovery
- Don't have to remember assert function names
PyTest
Do this...
def test_true():
assert 1, True
Instead of...
import unittest
class TestMyStuff(unittest.TestCase):
def test_the_obvious(self):
self.assertEqual(True, True)
if __name__ == '__main__':
unittest.main()
