Relevant for: API testing only
UFT One enables you to create custom API testing activities to extend the capabilities of the product.
Once you create a new activity through this mechanism, it is available in the Toolbox pane for all future tests.
For most custom activities, you can use the Activity Wizard. For C# users, the wizard creates a Visual Studio project into which you can add your own C# code. Java users can edit .java files which will be compiled into .class files. You then deploy the new activity into UFT One. For details, see Use the Wizard to create a custom Activity - C#.
Advanced users can build custom activities manually, without the wizard. For details, see Manually create a custom Activity in C#.
