Q24. Explain what VBScript is.

Ans: Visual Basic Script (VB Script) is a stripped-down version of Microsoft Visual Basic. It is similar to JavaScript and is a client-side scripting language. Both Visual Basic and VBScript have a lot in common.

Q25. Mention the environments where VBScript could run?

Ans: The three different settings VBScript can use are as follows:

  • WSH (Windows Script Host) – The native hosting environment of the Windows OS 
  • IIS (Internet Information Server) – Microsoft's web server
  • Internet Explorer (IE) - The most basic hosting environment in which we can run VBS.

Q26. What is VBScript language used for, and in which language it’s modeled?

Ans: VBScript is a simple scripting language used in the QTP (Quick Test Professional) application to automate scripts. It focuses on the Visual Basic programming language.

Q27. Explain what loose binding is? Why is it not a good practice to use it?

Ans: Loose binding is a feature of VBScript that allows you to use variables without declaring them. It is not a good idea because VBScript will not notify you if you misspell the same variable when you use it again.

Q28. Mention what variant is in VBScript?

Ans: In VBScript, a data type represents a variant. A Variant can store a string or numeric data. When used in a string context, a Variant behaves as a string, and when used in a number context, it acts as a number.

Q29. Mention what VBScript Procedures are?

Ans: Procedures in VBScript can organize and reuse code. Sub procedures and Function procedures are the two most common types of VBScript procedures.

Q30. Mention when to use Function procedures and what are its characteristics?

Ans: When you wish to run a set of statements and get a result, you utilize Function procedures. A few of its characteristics are listed below:

  • Function and Conclude used to begin and end function procedures. Statements of function
  • A function process can accept or reject the input.
  • By assigning the matter to its name, function procedures return a value.

Q31. Mention the rules for using Option Explicit statements?


  • Before any other statements, the Option Explicit statement should appear in a script. If this isn't the case, a non-trappable error will occur.
  • An error occurs if you attempt to use an undeclared variable name.
  • Option Explicit uses all variables and must be declared using the Dim, Public, Private, or ReDim commands.

Q32. Which data types support  VBScript language?

Ans: The VBScript language only supports one data type, referred to as a 'Variant.' When this data type uses a String context, it behaves like a String, and when used in a Numeric context, it acts like a Number. The Variant data type excels in this area.

Q33. How do I declare a global variable in VBScript?


  • Dim: It  is short for "local scope." if the variable name does not already exist globally 
  • Global: forces the variable to create in the Global scope.
  • Local: forces the variable to create in the Local/Function scope.

Q34. What is the use of an Option Explicit Statement?

Ans: https://cdn.mindmajix.com/blog/images/on-error-command-291121.png The Option Explicit statement establishes a system in which all variables must define using Dim, Public, or Private Statements before using the Script. It is good to put 'Option Explicit” at the top of the code so that you can quickly correct it without causing any confusion if you accidentally use the false variable name.

Q35. What are the two ways in which a variable gets declared in the VBScript language?


  • Implicit Declaration Variables: Implicit Declaration occurs when variables are used directly without being declared. It’s not a good practice because if the variable name is written wrong in the Script, the results will be erroneous when executed. It may be difficult for the user to recognize in some situations.
  • Explicit Declaration Variables: Explicit Declaration of Variables is the process of declaring variables before utilizing them.

Q36. How can constants be declared in the VBScript language?

Ans: Constants are named memory regions in a program that never alters their values while the script is running. In the VBScript language, the 'Const' keyword declares Constants.

Q37. How many types of Operators are available in the VBScript language?


  • Arithmetic Operators
  • Comparison Operators
  • Logical Operators
  • Concatenation Operators

Ans: Decision testing or Branch testing is a type of testing that ensures that each of the possible branches from each decision point gets tested at least once, guaranteeing that all reachable code gets tested.

Q51. What is integration testing?

Ans: After unit testing, integration testing goes through. We test a group of linked modules in integration testing. Its goal is to identify faults with module interaction.

Q52. What is Automation Testing?

Ans: Automation testing is a sort of software testing that entails using an automation tool to execute automated test cases. It reduces test execution time by allowing test scripts to be created once and run several times without the need for human intervention.

Q53. What do you mean by Software Testing?

Ans: The process of evaluating a system to see if it meets its business requirements is known as software testing. It analyzes the system's overall quality in terms of properties such as correctness, completeness, usability, and performance. It is used to ensure the quality of software to the application's stakeholders.

Q54. Why is testing required?

Ans: For the following reasons, we require software testing:

  • Testing ensures that the product functions as intended for the stakeholders.
  • Unable faults are leaked to the end-user/customer without effective testing, negatively affecting the development organization.
  • Defects recognized early in the SDLC result in lower repair costs and resource utilization.
  • Reduces development time by discovering difficulties earlier in the process.
  • By providing a different perspective on the product development process, the testing team offers another dimension to software development.

Q55. What is Quality Assurance, and what are the different activities involved in Quality assurance?

Ans: Any systematic process verifying whether a product or service fulfills defined requirements is known as quality assurance (QA). Process checklists, process standards, process documentation, and project audit are examples of quality assurance activities.

Q56. What is Quality Control, and what are the different types of testing involved in QC?


  • Quality control is a product-driven method that ensures the generated product meets all of the specifications.
  • It's regarded as a corrective measure because it inspects the finished product for flaws. It includes several sorts of testing, such as functional, performance, and usability, among others.

Q57. What is the difference between Verification and Validation?


                           Verification                                                                                              Validation

Verification is the process of assessing artifacts and the software development process to ensure that the generated product meets the criteria.

The process of validating that the generated software product meets the defined business criteria is known as validation.

It is a static process of document analysis rather than the outcome.

It entails executing a software product and performing dynamic testing on it.

Verification is a method that focuses on the process.

Validation is a method that focuses on the product.

Compared to errors discovered during the validation process, errors found during verification require less cost/resources to repair.

Errors discovered during validation necessitate more money and resources. When an issue is detected later, the cost of repairing it increases.

Q58. Explain the STLC – Software Testing life cycle.

Ans: All operations conducted during the testing of a software product refer to the software testing life cycle. The phases are as follows:

  • Requirement analysis and validation: The scope of testing is determined, and the requirements papers are analyzed and validated during this step.
  • Test planning: In this phase, the test plan approach gets created, and the estimation of test workload, automation strategy, and tool selection.
  • Test Design and Analysis: This step involves the creation of test cases, the preparation of test data, and the implementation of automation scripts.
  • Test environment set up: A test environment that closely resembles the real-world environment gets created.
  • Test execution: Problems get resolved, report about bugs and retested.
  • Test Closure and reporting: The final test results summary, learning, and test metrics get included in the test closure report.

Q59. What are some advantages of automation testing?

Ans: The following are some of the benefits of automation testing:

  • Test execution via automation is quick and saves a significant amount of time.
  • Carefully written test scripts eliminate the possibility of human error during testing.
  • CI tools like Jenkins, configured to provide daily test results to relevant stakeholders, can schedule test execution for a nightly run.
  • Automation testing requires very few resources. Once the tests are automated, QAs spend almost no time on test execution. QA bandwidth will save for other exploratory tasks.

Q60. What are some disadvantages of automation testing?

Ans: Some of the drawbacks of automation testing are as follows:

  • Writing test scripts necessitates the use of skilled automation testing experts.
  • Scriptwriting takes time and effort in the beginning.
  • Automation scripts only validate the coded tests. These tests may miss some errors that are obvious and easily identified by humans (manual QA).
  • Even minor changes to the application necessitate script updates and maintenance.

Q61. What are the attributes of a test case? 

Ans: The following are the various properties of a test case that make it more trustworthy, clear, and concise while avoiding or reducing repetition.

  • TestCaseId
