System Testing

System Testing is a type of Functional Testing that focuses on testing the entire system as a whole. System testing is generally performed after Integration Testing and before Acceptance Testing. The goal of system testing is to ensure that the system as a whole meets the functional, performance, and security requirements specified in the requirements document.

Syntax

There is no specific syntax for carrying out System Testing. It involves the following general steps:

1. Understand the requirements of the system
2. Develop system test cases and scripts
3. Prepare test data and test environment
4. Execute the system test cases
5. Report and track the defects found during testing
6. Regression testing and retesting to ensure proper defect resolution

Example

An example of system testing is to test the entire functionality of an eCommerce platform, including searching for products, adding items to a cart, and checking out, to ensure that all functionalities work together seamlessly and meet the requirements specified in the requirements document.

Output

The output of system testing includes a test report that details the test cases executed, their results, and any defects found during testing. The final output of successful system testing is a ready-to-launch system that meets all functional, performance, and security requirements specified in the requirements document.

Explanation

System testing is an essential part of software testing as it helps ensure that the system as a whole meets all functional, performance, and security requirements. The focus of system testing is on the system as a whole, and not just individual components. System testing ensures that all components work together seamlessly, including third-party integrations, APIs, and databases.

Use

System testing is used to test the entire system to ensure that it meets functional, performance, and security requirements and is ready for launch. It is beneficial for both the development team and the end-users of the system.

Important Points

• System testing is performed after Integration Testing and before Acceptance Testing.
• The goal of system testing is to ensure that the system as a whole meets the functional, performance, and security requirements specified in the requirements document.
• System testing is carried out in an environment that is as close to the production environment as possible to ensure accuracy.
• System testing is often performed using Automated Testing tools.

Summary

System Testing is a type of Functional Testing that focuses on testing the entire system as a whole. The goal of system testing is to ensure that the system meets the functional, performance, and security requirements specified in the requirements document. It is an essential step in software testing, carried out after Integration Testing. The output of system testing includes a test report that details the test cases executed, their results, and any defects found during testing.
