Ques:- What is Virtual Users?
Asked In :-
Right Answer:
Virtual users are simulated users created by performance testing tools to mimic real user interactions with an application during load testing. They help assess how the application performs under various levels of user load.

Ques:- Please any on explain usage of “on error resume next”,”Onerror goto 0″ with sample code….Thankyou………when a tester is asked to execute 100 scripts in a shorttime..(the server will be down in another 10 min)..how hehas to run those scripts?
Asked In :-
Right Answer:
`On Error Resume Next` is used in VBScript to ignore runtime errors and continue executing the next line of code. `On Error GoTo 0` disables this error handling, allowing the script to stop on errors.

**Sample Code:**
```vbscript
On Error Resume Next

' Attempt to open a non-existent file
Dim fso, file
Set fso = CreateObject("Scripting.FileSystemObject")
Set file = fso.OpenTextFile("nonexistent.txt")

If Err.Number <> 0 Then
WScript.Echo "Error occurred, but continuing..."
Err.Clear ' Clear the error
End If

' Continue with other operations
WScript.Echo "Continuing with the script..."

On Error GoTo 0 ' Disable error handling
```

To execute 100 scripts in a short time when the server will be down in 10 minutes, the tester can use a loop to run the scripts concurrently or in quick succession, ensuring to handle
Ques:- What is show stopper bug pls explain,pls give any real timebug u get in your project
Asked In :-
Right Answer:
A show stopper bug is a critical defect that prevents the software from functioning at all, making it impossible to proceed with testing or use the application. For example, if a banking application crashes when a user tries to log in, this would be a show stopper bug, as it halts all user access to the system.

The Whitebox Testing section on takluu.com is designed for QA professionals, testers, and developers who want to master the internal testing techniques crucial for delivering high-quality software. Whitebox testing, also known as structural or glass-box testing, involves examining the internal logic, code structure, and workflows to ensure thorough test coverage and bug detection.

This category covers essential concepts such as code coverage metrics (statement, branch, path coverage), control flow testing, data flow testing, unit testing frameworks, and debugging techniques. You’ll also learn about writing effective test cases, identifying edge cases, and using automation tools that support whitebox testing.

Whitebox testing is vital in detecting hidden errors early in the development cycle, improving code quality, and facilitating continuous integration and deployment. This section provides practical interview questions and detailed explanations to help you understand how whitebox testing differs from blackbox testing and when to apply each.

You will also find scenario-based questions frequently asked in QA and software developer interviews that test your understanding of testing methodologies, code instrumentation, and test-driven development (TDD).

Whether you’re preparing for roles such as QA Engineer, Software Tester, or Automation Engineer, this section equips you with the knowledge and skills to perform effective whitebox testing and confidently answer related interview questions.

At Takluu, we focus on practical learning, ensuring you can apply whitebox testing techniques in real projects and succeed in your career journey.
