Tutorial 27 - All about user defined functions in QTP

This tutorial describes how you could use Functions in QTP



Video Transcript with Key Takeaways highlighted

* If you have segments of code that you need to use several times in your tests, you may want to create a user-defined function. By using user-defined functions, your tests are shorter, and easier to design, read, and maintain
* Your own function libraries, can contain VBScript functions, subroutines, modules etc.
* You need to follow 3 simple steps to use a function from a library in your test
* To create a new function library in QTP
* Select File > New > Function Library. It opens as a new tab in QTP
* Lets a create a very simple function which shows Message Box.So whenever this function is called a message box must be displayed
* You can have mutliple functions defined in the same file.Let's save the function
* A function has an extension .qfl
* Next Step Associate the library with your test
* Click File > Settings > Resources > Associate Function Library.Click Add. Select The Function Library File.Click Okay
* Last step to use the function
* In your test simply call the function. When you run the test as expected Message Box is displayed
* Using COM , DCOM objects you can create very advanced Functions
* Infact, many of the features provided by QTP can be coded using VBScript
* We have seen automation engineers who make it more of a VB project rather than automation project
* Our recommendation is to focus on 100% automation rather than flaunting your VB skills
