Manual QA: Testing for Beginners - Types of QA Testing - Part 9

Summary

In this QA tutorial, Alex USA Days discusses various types of software testing, including black box, white box, and gray box testing. He also covers positive and negative testing, functional and non-functional testing, and common types like acceptance, regression, API, exploratory, boundary, smoke, and beta testing. The video also touches on stress, load, accessibility, localization, and security testing, highlighting their importance in the QA process. Alex encourages viewers to explore the provided links for a deeper understanding of each test type.

Takeaways

• 📚 There are over 100 types of software testing methods, but QA professionals typically use around five to seven main types.
• 🔍 The three main categories of testing are Black Box (no access to internal code), White Box (access to internal code), and Gray Box (partial access to internal code).
• 🔑 Positive testing checks the application works as expected under normal conditions, while negative testing simulates incorrect user actions to see how the application handles errors.
• 🔄 Functional testing is based on requirements and acceptance criteria, ensuring the application performs its intended functions.
• 💡 Non-functional testing focuses on the system's stability, performance, and security rather than its features.
• 🎯 Acceptance testing confirms that features meet business requirements and are ready for release.
• 🔄 Regression testing is crucial for verifying that new changes or bug fixes do not break existing functionality.
• 🌐 API testing checks the communication between the front end and back end of an application.
• 🔍 Exploratory testing relies on the tester's experience to discover bugs by navigating and interacting with the application in unconventional ways.
• 🚦 Boundary testing verifies the application's behavior at the edge of input value ranges, ensuring it correctly handles minimum and maximum values.
• 🌬️ Smoke testing is a preliminary check to ensure the basic functionality of an application is intact before proceeding with more detailed testing.

Q & A

What is the primary focus of the video by Alex USA Days?

The video focuses on explaining various types of software testing, their purposes, and how they are conducted within the quality assurance process.

How many types of testing are mentioned in the video?

The video mentions around 100 different types of testing, but emphasizes that one doesn't need to remember all of them, just be aware of their existence.

What are the three main categories of testing discussed in the video?

The three main categories of testing discussed are black box testing, white box testing, and gray box testing.

What is the difference between black box and white box testing?

Black box testing is when you have no knowledge of the system's internal workings, while white box testing involves having access to the code and understanding the internal functions.

What is meant by positive and negative testing?

Positive testing, also known as happy path testing, verifies the application's functionality as intended by the user. Negative testing involves providing invalid input or performing unexpected actions to see how the application handles them.

What is the purpose of functional and non-functional testing?

Functional testing checks the application against its requirements and acceptance criteria, ensuring it performs its intended functions. Non-functional testing focuses on the system's stability, performance, and other attributes that don't directly relate to its functionality.

Why is acceptance testing important?

Acceptance testing is crucial as it verifies that features are implemented according to business requirements, ensuring the application meets the expectations of the end users.

What is the role of regression testing in the QA process?

Regression testing is performed to ensure that new changes, bug fixes, or releases have not introduced new issues or broken existing functionality.

Why is API testing considered important in the context of automation testing?

API testing is significant in automation testing because it verifies the communication between the front end and back end. It's a good starting point for those looking to transition from manual testing to automation.

What is exploratory testing and how does it differ from other testing methods?

Exploratory testing relies on the tester's experience and approach to discover bugs by navigating outside of standard testing processes. It's less structured and more flexible compared to other testing methods.

Can you explain the concept of boundary testing with an example?

Boundary testing involves verifying the boundary values of input ranges. For example, if an application allows use only for individuals aged between 21 and 100, boundary testing would check that a 21-year-old can use it (positive test), a 20-year-old cannot (negative test), a 100-year-old can (positive test), and a 101-year-old cannot (negative test).

What is the significance of smoke testing in the QA process?

Smoke testing, also known as sanity testing, is an initial verification to ensure that major functionality of the application works as expected. It's a preliminary check to determine if the build is stable enough to proceed with further testing.

What are the differences between closed and public beta testing?

Closed beta testing involves a limited number of users, while public beta testing is open to everyone. Both are conducted in a production environment to identify issues before the final release.

How does stress testing differ from load testing?

Stress testing aims to determine the stability and performance of an application under heavy loads or prolonged usage to find its breaking point. Load testing, on the other hand, measures how a system performs under expected heavy loads without the intention of breaking it.

Why is accessibility testing important?

Accessibility testing is crucial to ensure that the application is inclusive and usable by as many people as possible, including those with disabilities, by verifying features like speech recognition and compatibility with reading systems.

What is the primary objective of security testing?

The primary objective of security testing is to identify and fix system vulnerabilities and potential exploits early in the development process to prevent infiltration, data leaks, and cyber attacks.
