Summary: <p>Complete and exhaustive testing is not possible. Nor would it be fun, or maintainable, or a good use of your time.</p> <p>However, some functionality is important enough to make sure the test behavior coverage is thorough enough to have high confidence in it's quality.</p> <p>In this episode, we discuss 3 techniques that can be combined to quickly generate test cases. We then talk about how to implement them efficiently in pytest.</p> <p>The techniques covered are:</p> <ul> <li>equivalence partitioning</li> <li>boundary value analysis</li> <li>decision tables </li> </ul> <p>We discuss how to use these to generate test cases for a new list filter functionality in the cards application.</p> <p>The resulting tests:</p> <ul> <li>1 UI test to make sure the options are able to be passed in correctly.</li> <li>1 small parametrized test function with 16 single line parameter sets representing the different test cases.</li> </ul><p>Sponsored By:</p><ul> <li> <a rel="nofollow" href="http://amzn.to/2E6cYZ9">Python Testing with pytest</a>: <a rel="nofollow" href="http://amzn.to/2E6cYZ9">Simple, Rapid, Effective, and Scalable The fastest way to learn pytest.
