Writing test modules using standard interfaces and languages

Abstract

The focus of today's test system programmer is code reusability through common test modules. To achieve the greatest reusability these modules should be written using standard interfaces, such as DLLs and ActiveX automation servers. By using these standard interfaces inside an enterprise code modules can be used across development teams and in different projects. We discuss specifically: explaining the pros and cons of standard DLLs versus ActiveX/COM automation servers; programming these interfaces into test modules using standard programming languages, such as National Instruments LabWindows/CVI and Microsoft Visual Basic and Visual C++; integrating these interfaces into projects and test executives.
