Error Resume Next" statement. "On Error Resume Next" causes execution to continue with the statement immediately following the statement that caused the run-time error, or with the statement immediately following the most recent call out of qtp on error goto the procedure containing the "On Error Resume Next" statement. This allows execution to continue despite on error resume next in qtp example a run-time error. You can then build the error-handling routine inline within the procedure. An "On Error Resume Next" statement becomes inactive when on error goto 0 in qtp another procedure is called, so you should execute an "On Error Resume Next" statement in each called routine if you want inline error handling within that routine. When a procedure is exited, the error-handling capability reverts to whatever
On Error Resume Next Vbscript
error-handling was in place before entering the exited procedure. Use "On Error GoTo 0" to disable error handling if you have previously enabled it using "On Error Resume Next". It is not a good practice to use "On Error Resume Next" for entire test or project, this will suppress actual errors during execution and complicate debugging process. Just using "On Error Resume Next" will not help us, need to write proper error-handling routine. In QTP, .Sync on error resume next vba is the only method for which "On Error Resume Next" to be used, it is not so useful for other methods, you can use .Exist or check specific object property instead of "On Error Resume Next". Your code would get complicated if there are more error-handling routines. Enable error handling by using "On Error Resume Next" for necessary statements and disable error handling by using "On Error GoTo 0". Err object is part of VB Script, created and updated automatically. It contain information about the last error occurred in the script. Script engine will overwrite the error information when it encounters next error, information is not preserved. Always clear the object information once the error check is completed else same error information will cause issue in the next error check. Different methods associated with Err object Err.number - Contain value that contain error code, Zero no error occurred. Err.description - Descriptive message associated with the error. Err.source - Set name of the object or application where error generated. Err.helpcontext - Return value containing context id of the appropriate topic in the help file. Err.helpfile - Path of help file. Err.rise - Generate run-time error. Attaching sample code from my Dual-Function framework

- 11, as division by zero. Consider the situation where you are passing the above output as an input is some other function as input! What'll happen? Whole your test will be doing something unexpected and you http://bharath-marrivada.blogspot.com/2010/03/qtp-when-to-use-on-error-resume-next.html will end up with nothing other then confusions and looking in the code for What went wrong..... :) Example 2: Assume either because of some issue or unexpected behavior of the application, 'Login' button is not displayed. Now, if you run below code-- On Error Resume NextBrowser("mybrowser").Page("mypage").WebEdit("loginname").Set "abhikansh"Browser("mybrowser").Page("mypage").WebEdit("password").SetSecure "mypass"Browser("mybrowser").Page("mypage").WebButton("login").click wait 2 Browser("mybrowser").Page("NEWPAGE").WebLink("NEXT").click Expected Result: When you click on Login button, it should navigate to next page, where it will click on NEXT link. Actual http://www.qtpschool.com/2011/03/how-on-error-resume-next-can-be-problem.html Result : Even though the Login button is not displayed on the page, there will be no runtime error and because steps inside the 'On error resume next'. It will try to click on NEXT link, which is not appeared. It will keep executing all the following steps of the script without any error. But actually it will not achieve anything because application is still stuck on first page. So what's the lesson? Shall I avoid to use 'On error resume next'? No. Not at all! But be very careful while using. Remember.. "On Error Resume Next" is useful when you intentionally don't want to let errors occur i.e. any temporary browser specific error or printer error which is not about AUT (application under test), but as explained in above examples, it may work in wrong direction if not used properly.

On Error http://gareddy.blogspot.com/2013/01/on-error-resume-next.html Resume Next On Error GoTo 0 Remarks If you don't use an On Error Resume Next statement anywhere in your code, any run-time error that occurs can cause an error message to be displayed and code execution stopped. http://qaautomationqtp.blogspot.com/2013/04/error-handling-using-vbscript-in-qtp.html However, the host running the code determines the exact behavior. The host can sometimes opt to handle such errors differently. In some cases, the script debugger may be invoked at the point of the error. In still other on error cases, there may be no apparent indication that any error occurred because the host does not to notify the user. Again, this is purely a function of how the host handles any errors that occur. Within any particular procedure, an error is not necessarily fatal as long as error-handling is enabled somewhere along the call stack. If local error-handling is not enabled in a procedure and an error occurs, control is passed back through the call stack error resume next until a procedure with error-handling enabled is found and the error is handled at that point. If no procedure in the call stack is found to have error-handling enabled, an error message is displayed at that point and execution stops or the host handles the error as appropriate. On Error Resume Next causes execution to continue with the statement immediately following the statement that caused the run-time error, or with the statement immediately following the most recent call out of the procedure containing the On Error Resume Next statement. This allows execution to continue despite a run-time error. You can then build the error-handling routine inline within the procedure. An On Error Resume Next statement becomes inactive when another procedure is called, so you should execute an On Error Resume Next statement in each called routine if you want inline error handling within that routine. When a procedure is exited, the error-handling capability reverts to whatever error-handling was in place before entering the exited procedure. Use On Error GoTo 0 to disable error handling if you have previously enabled it using On Error Resume Next. The following example illustrates use of the On Error Resume Next statement. On Error Resume Next Err.Raise 6 ' Raise an overflow error. MsgBox "Error # " & CStr(Err.Number) & " " & Err.Description Err.Clear ' Clear the error. On Error - Example
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 occur. This error does not permit the automated test to navigate to the feature, screen, or module that needs to be tested. These unexpected errors and events are called exceptions.It becomes important to 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 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 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. Public Function FunctER() On error resume
