ISTQB FOUNDATION 4.0 | Tutorial 18 | Test Types | Functional Testing | Non-Functional Testing | CTFL

Summary

This tutorial delves into the ISTQB Foundation Level certification, focusing on Chapter 2.2, which discusses test types and levels within the software development lifecycle. The session clarifies the distinction between functional and non-functional testing, emphasizing their importance in ensuring the core functionalities and enhancing quality characteristics of a software application. Functional testing is about verifying the basic features, while non-functional testing evaluates attributes like performance, security, and usability. The tutorial promises to cover white box, black box, retesting, and regression in subsequent sessions, aiming to deepen understanding of these critical testing concepts.

Takeaways

• 📚 The tutorial is focused on the ISTQB Foundation Level certification, specifically Chapter 2 about testing throughout the software development life cycle.
• 🔍 The segment 2.2.2 discusses different types of testing, emphasizing the distinction between testing levels and types, such as static and dynamic testing.
• 🔑 Testing types are categorized into functional and non-functional testing, with functional testing targeting the core features and functionalities of the system.
• 💡 Non-functional testing is about enhancing the system's quality characteristics, such as performance, security, and usability, which are not the core functionalities but are essential for a high-quality product.
• 🔄 Functional testing levels include unit, integration, system, acceptance, component integration, and system integration, which are considered the standard levels for testing the core functionalities.
• 🌐 Non-functional testing levels are extensive and include performance, security, portability, usability, accessibility, recovery, and more, focusing on how the system works beyond its basic features.
• 🚀 The tutorial aims to clarify the confusion between testing types and levels, explaining that static and dynamic are methods of testing, whereas functional and non-functional are categories of what is being tested.
• 💬 The script uses examples like Google Pay and flight booking applications to illustrate the concept of core functionalities and how functional testing ensures they work as expected.
• 🛠️ Non-functional testing is described as optional but important for defining the quality of a product, addressing aspects like performance under load and security against unauthorized access.
• 📈 The tutorial mentions that there are over 50 levels of testing, highlighting the comprehensive nature of software testing to cover all aspects of a system's performance and quality.
• 🎓 The script reassures that while there are many non-functional testing levels, the syllabus does not require memorizing all of them for the ISTQB exam, focusing instead on understanding the concepts.

Q & A

What is the main focus of Chapter 2 in the ISTQB Foundation level certification tutorial?

The main focus of Chapter 2 is on testing throughout the software development life cycle, specifically discussing test levels and types in segment 2.2.

What is the difference between 'testing levels' and 'testing types'?

Testing levels refer to the stages in the software development process where testing is conducted, such as unit, integration, and system testing. Testing types, on the other hand, refer to the different approaches to testing, such as functional, non-functional, white box, and black box testing.

What are the two main categories of testing levels mentioned in the script?

The two main categories of testing levels are functional and non-functional testing.

What is functional testing?

Functional testing is about testing the core features and functionalities of the system, ensuring that the system performs the tasks it is expected to do.

Can you give an example of a core functionality in an application?

An example of a core functionality is the ability of Google Pay to transfer money from one account to another, including features like bill payment and QR code scanning for payments.

What are some common functional testing levels?

Common functional testing levels include unit, integration, system, acceptance, component integration, and system integration.

What is non-functional testing?

Non-functional testing is about enhancing the quality characteristics of the system, such as performance, security, usability, and accessibility.

Why is non-functional testing important?

Non-functional testing is important because it ensures that the application not only has the necessary core functionalities but also performs well under various conditions, such as handling high loads or securing sensitive data.

What are some examples of non-functional testing types?

Examples of non-functional testing types include performance testing, security testing, usability testing, accessibility testing, portability testing, and interoperability testing.

How many levels of testing are mentioned in the script?

The script mentions that there are over 50 levels of testing, including both functional and non-functional levels.

What is the purpose of the tutorial's next session?

The purpose of the next session is to discuss white box, black box, retesting, and regression testing, providing further understanding of these testing types.
