Python for Testing 101 (PT101)

About the course

This course introduces the core concepts of software testing, covering key testing methods, testing levels, and software quality best practices. You’ll learn how testing helps identify defects, improve reliability, and manage software releases effectively. The course explores manual and automated testing, different testing techniques, and how to structure testing efforts for better results.

The course covers topics such as error handling, debugging techniques, software testing levels (unit, integration, system, and acceptance), test documentation, and test coverage. You’ll also learn about industry best practices like the test pyramid, the DRY and KISS principles, and refactoring techniques to improve code quality. Additionally, the course introduces concepts from the ISTQB® methodology, including the 7 testing principles, test case design techniques, and the structured approach to testing in different software development models.

By completing this course, you’ll build a strong foundation in software testing and be prepared for the PCET™ – Certified Entry-Level Tester with Python certification.

This course is structured to help you learn both conceptually and practically. As you move through the modules, you will build knowledge, apply it in hands-on activities, and check your understanding along the way. Here’s what you can expect:

• Modules – the course is divided into four structured modules, each focused on a major stage of the data analytics workflow.
• Lessons – each module contains focused, step-by-step lessons that introduce concepts in a clear and beginner-friendly way.
• Interactive Features – in the premium version, lessons include quizzes, coding tasks, and practice activities to help you apply what you learn.
• Module Projects – at the end of each module, you will complete a practical project based on realistic data scenarios.
• Module Tests – each module ends with a test that helps you assess your understanding before moving on.
• Final Assessment – at the end of the course, you will complete a final assessment that brings together the most important skills and concepts from the full course.

Prerequisites

This course is designed for learners who:

• Have a basic understanding of Python programming concepts.
• Can write and debug simple Python programs.
• Want to build a strong foundation in software testing principles and methodologies.
• Aim to improve their ability to analyze software quality and reliability.

No prior knowledge of object-oriented programming (OOP) is required. This course is designed as a smooth transition from Python Essentials 1 to software testing, making it accessible for learners with basic Python experience.

Go Pro for Hands-on Practice & Course Diploma

The Pro version of the course includes a Diploma of Course Completion and gives you access to 40+ hands-on labs, interactive exercises, and quizzes designed to reinforce your learning and help you apply concepts in real-world scenarios. It also supports your preparation for the PCET™ certification exam by providing practical experience aligned with exam objectives.

Python code example

Here’s a real snippet from the course so you can see how we learn in practice. Here you can see a functional test, where we simulate a user attempting to log into a system by providing a username and password::

Source Code:

test_funcional.py

def test_login():
    # Simulate entering username and password
    username = "test_user"
    password = "test_pass"
    
    # Call the login function and check the result
    result = login(username, password)
    
    # Assert the login was successful
    assert result == "Login Successful", "Login Failed"

The test checks if the login() function correctly returns "Login Successful" when provided with valid credentials.
