A service virtualization tool is used to simulate the behavior of specific components in heterogeneous component-based applications such as APIs, services, and third-party apps that are not readily accessible during development and testing stages. These tools help create stable, controllable, and predictable testing environments by mimicking the interactions with the missing components. This is particularly useful when dealing with server or network traffic log data to develop a shareable testing service that replicates the real systems' behavior without their actual implementations.

Fault seeding and fault injection tools are used intentionally to introduce defects into a system or software to test the robustness of the test suite. This method helps in validating the effectiveness of the test processes and configurations by ensuring that the tests are capable of detecting and isolating inserted faults. It is a technique used to measure the quality of testing rather than debugging or performance compliance, which relates directly to the fundamental purpose of enhancing test coverage and the detection capability of the test suite .

An ISTQB defined technique for identifying risks when defining a risk-based approach to testing the performance efficiency of a new application is to analyze the requirements to look for areas where performance efficiency requirements have not been well-defined. This technique ensures that testing efforts are focused on areas of the application that are critical for performance but may have insufficient coverage in terms of detailed requirements​​.
