ISTQB FOUNDATION 4.0 | Tutorial 16 | Test Levels | System Integration Testing | CTFL | TM Square

Summary

This tutorial delves into the ISTQB Foundation Level certification, focusing on system integration testing within the SDLC. It explains the importance of testing interfaces and communications between systems, emphasizing the necessity in today's applications that often combine multiple systems. Examples like Zomato integrating Google Maps and Amazon's use of external payment gateways illustrate the concept. The video also highlights the need for suitable test environments resembling operational settings for effective system integration testing.

Takeaways

• 😀 System Integration Testing (SIT) is a level of testing that focuses on the interfaces and interactions between two or more systems.
• 🔍 SIT is not mandatory for all applications, especially simple ones that do not combine multiple systems into a final product.
• 💡 Modern applications often consist of combinations of applications, making SIT a relevant and necessary process in software development.
• 📍 SIT is concerned with the communication between the system under test and external systems or services, including those from different vendors.
• 🌐 An example of SIT is the integration of Google Maps within food delivery apps like Zomato, which is not a product of the app itself but is essential for order tracking.
• 🛠️ Suitable test environments that closely mimic the operational environment are preferred for SIT to ensure the functionality of the integrated systems.
• 🚫 SIT cannot always be conducted in the actual production environment due to cost, convenience, and the necessity of testing prior to release.
• 🔄 System integration can occur in various combinations, including software-software, software-hardware, and hardware-hardware integrations.
• 🛒 The script uses Amazon as an example of software-software integration, where Amazon integrates with external payment gateways to facilitate transactions.
• 📱 Embedded products such as smart devices and appliances represent software-hardware integrations, where software controls the hardware functions.
• 🏗️ Heavy machinery and amusement park rides exemplify hardware-hardware integrations, where different mechanical components work together to create a functional system.

Q & A

What is the main focus of the tutorial video?

The tutorial video focuses on explaining the concept of System Integration Testing at the ISTQB Foundation level, its importance, and how it is applied in different scenarios.

What does System Integration Testing involve?

System Integration Testing involves testing the interfaces of the system under test and any other systems or external services that it communicates with, ensuring they work together as expected.

Why is it not mandatory for every application to go through System Integration Testing?

Not every application has to go through System Integration Testing because not all applications are a combination of multiple systems or have integrations with external systems or services.

What is an example of System Integration Testing in a real-world application?

An example of System Integration Testing is Zomato integrating with Google Maps to track the delivery of orders, which is a combination of two different systems working together.

Why is it important to have a test environment similar to the operational environment for System Integration Testing?

A test environment similar to the operational environment is important for System Integration Testing because it helps ensure that the final functional product will work correctly in real-world conditions.

What are some of the challenges in using the real environment for System Integration Testing?

Some challenges in using the real environment for System Integration Testing include the inability to test before release (as it would require testing in production), and it may not be cost-effective or convenient to set up the real environment for initial levels of testing.

What are the three different combinations in which System Integration Testing can occur?

The three different combinations in which System Integration Testing can occur are software-software, software-hardware, and hardware-hardware integrations.

Can you provide an example of software-software integration in System Integration Testing?

An example of software-software integration is Amazon's e-commerce platform integrating with various payment gateways like Visa, MasterCard, and net banking services from different banks for processing payments.

What is an example of software-hardware integration in System Integration Testing?

An example of software-hardware integration is the combination of software with hardware in embedded systems such as smart appliances, smartphones, or IoT devices.

What is an example of hardware-hardware integration in System Integration Testing?

An example of hardware-hardware integration is amusement park rides like roller coasters, which are combinations of various mechanical and electrical components from different manufacturers.

What is the significance of System Integration Testing in the context of modern applications?

The significance of System Integration Testing in modern applications is that most applications today are a combination of multiple systems or services, and ensuring they work together seamlessly is crucial for the application's success.
