SetLastError Statement

Abstract

The SetLastError statement is used to set the latest error found in the execution or the run. The statement in itself falls under the category of utility statements and not utility objects. Remember there is a difference between utility statements and utility objects.

Before we dig down deep into the usage let’s quickly visit some general questions.

In the interview usually, you might be questioned in different ways like:

1. How to set error during the test run?
2. Can you associate the SetLastError statement value to DescribeResult statement?
3. What are the objects and parameters of SetLastError statement?
4. is SetLastError is an object or statement?
5. How can you show the description of last error occurred in the execution?
   

Discussion

When you create the test using some framework like hybrid, keyword driven or data driven, there is always a possibility of running into error. There are various errors which occur in the execution these can be math related, object related, system related etc. Whatever the case be if you want to proceed to next step by capturing the old error for later references then you can set via statement SetLastError .

Usually tester use the on error goto statement to return the code status to 0. But it’s a good practice to keep the error description in the log so that later you can analyze the log for pass and failures.

Hence, officially the main purpose of the SetLastError statement is to insert a VBScript error into the test script. All the error code relating to Microsoft Windows Script can be found at Microsoft site.

Syntax

Let’s see the parameters and their usage description for this statement:

Example

In the following example, the script fails to run successfully because the Password Image was not found on the Mercury Tours page and uses the SetLastError function to place the “Out of memory” error into the test script

The error code of the error can be retrieved using the GetLastError statement, and then the DescribeResult statement displays the text description of the error code in a message box.

Browser("Mercury Tours").Page("Mercury Tours").Image("Password").Click 21, -11
