Feature- en prestatietests

In deze oefening ga je verder met het testen van de pandas-datapijplijn. Je maakt hier twee soorten tests: een featuretest met pytest om te valideren dat de feature "het vinden van een mediangetal voor het salaris in het jaar 2022" daadwerkelijk werkt, en een prestatietest met pytest-benchmark om te meten hoe snel het proces is met pytest-benchmark. Let op: de functienaam testreadingspeed() in de oplossing wordt gebruikt om de performance te benchmarken. Dit is in lijn met de naamgevingsconventie en functionaliteit.

Learn what a test is and how to run the first one of your own with the pytest library! You will get used to the pytest testing framework and the command-line interface. You will also learn how to process specific contexts, like "failed tests" and "skipping the test" with pytest markers.

Exercise 1: Introduction to Testing in Python Exercise 2: The first test suite Exercise 3: pytest.raises Exercise 4: Invoking pytest from CLI Exercise 5: Run the test!Exercise 6: Run with the keyword Exercise 7: Applying test markers Exercise 8: Markers use cases Exercise 9: Failed tests with xfail Exercise 10: Conditional skipping

Learn what a fixture is and how to simplify your code by using it in tests. You will get familiar with the fixture @pytest.fixture decorator and the fixture tools. You will analyze your code to see the "fixture part" in it. Finally, learn how to use teardowns to prevent software failures.

Exercise 1: Introduction to fixtures Exercise 2: Getting familiar with fixtures Exercise 3: Data preparation Exercise 4: Run with a fixture Exercise 5: Chain Fixtures Requests Exercise 6: Chain this out Exercise 7: List with a custom length Exercise 8: Fixtures autouse Exercise 9: autouse statements Exercise 10: Auto add numbers Exercise 11: Fixtures Teardowns Exercise 12: Data with teardown Exercise 13: Read data with teardown

Learn what the basic testing types are and their features. Learn about test cases and how they help to implement tests. You will get more skilled with creating test functions and running pytest from CLI in IDE exercises. Finally, you will be able to differentiate the different testing types and create tests for each of them.

Exercise 1: Unit testing with pytest Exercise 2: Unit testing terms Exercise 3: Cover more test cases Exercise 4: Factorial of number Exercise 5: Run factorial Exercise 6: Feature testing with pytest Exercise 7: Feature or unit testing Exercise 8: Aggregate with sum Exercise 9: Integration testing with pytest Exercise 10: Integration test or not Exercise 11: Read the file Exercise 12: Performance testing with pytest Exercise 13: What is performance testing?Exercise 14: Finding an element Exercise 15: Speed of loops

In this final chapter, you will meet the unittest framework. First, you will learn basic assertion methods, then its CLI interface, and how to use fixtures. Finally, you will put everything together in the practical examples of data pipelines.

Exercise 1: Kennismaken met Unittest Exercise 2: Faculteit met unittest Exercise 3: Priem of niet Exercise 4: CLI-interface Exercise 5: Voer factorial uit met unittest Exercise 6: Foutieve faculteit Exercise 7: Unittest-opties Exercise 8: Fixtures in unittest Exercise 9: Test de stringvariabele Exercise 10: Palindroomcontrole Exercise 11: Praktische voorbeelden Exercise 12: Integratie- en unittests Exercise 13: Feature- en prestatietests
