- For an in-depth view of the required syntax, you can define a function using
the Function Definition Generator and experiment with the various options.
- When you register a function, it applies to an entire test object class. You
cannot register a method for a specific test object.
- If you want to call a function from additional test objects, you can copy
the RegisterUserFunc line, paste it immediately
after another function and replace any relevant argument values.
- It is recommended to include the RegisterUserFunc statement in the function library
so that the method will be immediately available for use in any component using
that function library.
- To use an Option Explicit statement in a
function library associated with your component, you must include it in all the
function libraries associated with the component. If you include an Option Explicit statement in only some of the
associated function libraries, QuickTest ignores all the Option Explicit statements in all function
libraries. You can use Option Explicit
statements directly in your action scripts without any
- Each function library must have unique variables in its global scope. If you
have two associated function libraries that define the same variable in the
global scope using a Dim statement or define two constants with the same name,
the second definition causes a syntax error. If you need to use more than one
variable with the same name in the global scope, include a Dim statement only in
the last function library (since function libraries are loaded in the reverse
- By default, steps that use user-defined functions are not displayed in the
test results tree of the Test Results window after a run session. If you want
the function to appear in the test results tree, you must add a Reporter.ReportEvent statement to the function
code. For example, you may want to provide additional information or to modify
the component status, if required.
- If you delete a function in use from an associated function library, the
component step using the function will display the icon. In subsequent run sessions
for the component or business process test, an error will occur when the step
using the non-existent function is reached.
- If another user modifies a function library that is referenced by a
component, or if you modify the function library using an external editor (not
QuickTest), the changes will take effect only after the component is
- When more than one function with the same name exists in the function
library, the last function will always be called. To avoid confusion, make sure
that you verify that within the resources associated with an application area or
component, each function has a unique name.
- You can re-register the same method to use different user-defined functions
without first unregistering the method. However, when you do unregister the
method, it resets to its original QuickTest functionality (or is cleared
completely if it was a new method), and not to the previous registration.
For example, suppose you enter the following statements:
RegisterUserFunc "Link", "Click", "MyClick"
RegisterUserFunc "Link", "Click", "MyClick2"
UnRegisterUserFunc "Link", "Click"
After running the UnRegisterUserFunc statement, the Click method stops using the functionality defined
in the MyClick2 function, and returns to the
original QuickTest Click functionality, and not
to the functionality defined in the MyClick
