APITester - Test any COM component using its typelibrary

 COM components are often used in backend, require elaborate workflows, complex GUIs. For ad hoc testing at for example customer site with specific inputs, separate test application needs to be created.

APITester tries to solve this problem, It reads the typelibrary and presents a simple user interface that lists  exposed apis and their parameters as shown below.  Further more the executed functions are saved and restored reducing the burden of reentering details. Also the logging shows previously executed apis.

components can be selected from COM+ application as shown below.

 or manually from typelibrary as below

After selecting the component the drop down lists all possible APIS. For VARIANT data types, a specific data type can be selected from the dropdown list. Data can be entered in the value column.

Upon executing by clicking ! button, the results are added to the log.
