You configure these options using the Sequence and Preconditions Editors included with the toolkit. All test sequence information is stored in test sequence files for retrieval on the actual test system. You receive the source code and user interface files for the entire Test Executive application in the toolkit. The Test Executive includes example test sequences and test source code so you can quickly learn how the Test Executive works and start building your own test sequences. In addition, a collection of test templates are included in source code that illustrate commonly used testing operations to help you get started.
External modules can be source files, object modules, or DLLs.
Therefore, you can build your test programs using any language capable of creating DLLs and you will not experience any performance limitations or be required to add any additional interface code to communicate with the test executive.
