toError Handling using vbscript in QTP: Unexpected events during a test run disrupt a test or may give invalid test results. For example, during a test run, an application error may vbscript resume on error occur. This error does not permit the automated test to navigate to the
Vbscript On Error Resume Next
feature, screen, or module that needs to be tested. These unexpected errors and events are called exceptions.It becomes important to
Vbscript Clear Error
handle these exceptions so that we are able to continue with automated testing even in unattended mode. Handling of exception in a manner so that test execution is uninterrupted is known as https://technet.microsoft.com/en-us/library/ee692852.aspx error handling. Following are the ways in which error handling can be implemented in QTP. •VB Script Error Handling oUsing Test Settings oUsing On Error Statement oUsing Err Object Properties oUsing Exit Statement •Recovery Scenarios Test Settings : Error Handling Error Handling can be defined in Test Settings through File>Settings>Run as shown below: It defines the possible actions in case anerror is encountered during run session http://qaautomationqtp.blogspot.com/2013/04/error-handling-using-vbscript-in-qtp.html Test Settings for error handling Using On Error Statement •On Error Statement On Error statement, which informs theVBScriptengine of intention to handle errors by self, rather than to allow theVBScriptengine to display a typically uninformative error message and halt the program. This is done by inserting a statement like the following at the start of a procedure: •On Error Resume Next: On Error Resume Nexttells theVBScriptengine that, should an error occur, we want it to continue executing the program starting with the line of code that directly follows the line in which the error occurred. •On ErrorGoto 0: This turns off the error handling Err Object Properties and Methods TheErrobject is part of theVBScriptlanguage and contains information about the last error to occur.Some of the most useful properties and method of Err object are as follows: Err.Number Property:TheNumberproperty returns or sets a numeric value specifying an error. Number is theErrobject's default property.If the value ofErr.Numberis 0, no error has occurred. Err.Description Property:TheDescriptionproperty returns or sets a descriptive string associated with an error. Err.Clear Method:TheClearmethod clears all property settings of theErrobject. Following is a code snippet how error handling can be implemented programmatically.

Catch ex 'What do I do here? End Try but I'm getting the error Statement expected in the catch clause. Does anyone know how I can catch/throw exceptions in VBScript using try/catch? (I am not error handling in looking for solutions with On Error Do X.) vbscript try-catch share|improve this question asked Feb 15 '11 at 2:25 Mehrdad 103k64310612 3 Then you're going to be very disappointed. There's no Try-Catch support in pre-.NET versions of VB, including VB 6, VBA, and VBScript. On Error Resume Next isn't so bad if you know how to use it correctly. –Cody Gray Feb 15 '11 at 8:35 Yeah, I am disappointed. :( On Error Resume Next used to be my favorite command back in middle school, when I learned VB 6... it quickly became my most hated command after I learned C#. I guess I'll use it but I really don't want to. –Mehrdad Feb 15 '11 at 8:44 See below for some tips on using it correctly! :-) –Mark Ribau Sep 8 '11 at 5:30 add a comment| 4 Answers 4 active oldest votes up vote 16 down vote accepted VBScript doesn't have Try/Catch. (VBScript language reference. If it had Try, it would be listed in the Statements section.) On Error Resume Next is the only error handling in
