Intertester

Intertester is a term used in English to describe a person or role involved in testing across interfaces, systems, or testers. It is not a standardized job title, and its meaning varies by discipline, leading to multiple related interpretations.

In software engineering, an intertester may refer to a tester who focuses on the interactions between components, modules, or services. This involves integration and interface testing, contract testing, and cross-system workflows to ensure data exchange and compatibility across boundaries. The aim is to detect issues that arise only when components interact, rather than when they function in isolation.

In research and psychometrics, intertester commonly denotes a tester who administers assessments or coding schemes to participants. Such use highlights the importance of intertester reliability—the degree to which different testers produce consistent results. Calibration, training, and shared scoring guidelines are essential to establish reliability in this context.

In usability testing or education, the term can describe testers who operate across platforms or who administer standardized examinations and protocols. Here, intertester consistency is again a concern, requiring clear procedures and, where possible, parallel or duplicate assessments to verify results.

Reliability and quality assurance depend on clear definitions, standardized procedures, and ongoing calibration among testers. While intertester practices vary by field, the underlying goal is to ensure that testing outcomes are accurate, reproducible, and comparable across different testers and contexts.
