1. System Under Test (SUT)
The System Under Test (SUT) is the specific software application, component, or system that is being subjected to testing. It is the main focus of the testing process and represents the software or system that developers and testers are working on. The SUT could be a single software application, a module within a larger system, or even an entire software ecosystem. The primary goal of testing the SUT is to identify and evaluate its behavior, functionality, performance, and other relevant aspects to ensure that it meets the intended requirements and functions correctly.
2. Testing Environment
A Testing Environment refers to the setup or configuration in which the testing of the System Under Test (SUT) takes place. It encompasses the hardware, software, network, and other resources required to execute the tests effectively and efficiently. Creating an appropriate testing environment is essential to simulate real-world scenarios and conditions that the SUT would encounter once it's deployed. A testing environment can be tailored to mimic the production environment as closely as possible, allowing testers to uncover potential issues and defects that might arise in real-world usage.
The testing environment can be categorized into different types:
-
Development Environment: This is where the development team creates and modifies the software. It's typically more flexible and may not exactly resemble the production environment.
-
Testing/Staging Environment: This is where testing activities take place. It should closely resemble the production environment but is separate from it to prevent any impact on real users.
-
Production Environment: This is the live environment where the software or system is used by end-users. Testing here is minimal to avoid disruption.
-
QA Environment: Similar to the testing environment, this is a dedicated environment for Quality Assurance (QA) activities, ensuring that the software is ready for production.
-
Integration Environment: This environment is used to test the integration of different software components or modules before they're combined into the complete SUT.
-
Performance Testing Environment: Specifically designed to test the performance and scalability of the SUT under different loads and conditions.
-
Security Testing Environment: Focused on identifying vulnerabilities and security issues within the SUT.
-
User Acceptance Testing (UAT) Environment: This environment allows end-users or clients to test the software before it's deployed, ensuring it meets their requirements.文章来源：https://www.toymoban.com/news/detail-656642.html
Creating and maintaining appropriate testing environments is crucial for reliable and effective testing. Differences between testing and production environments can sometimes lead to unexpected issues, so efforts are made to minimize such discrepancies and ensure accurate testing results.文章来源地址https://www.toymoban.com/news/detail-656642.html
