Software Testing and Quality Control Questions

Multiple choice technology testing

Which statement below is true about Wait method?

  1. Wait – makes a wait for the specified seconds with optional milliseconds

  2. Wait – makes a wait for the specified seconds only

  3. Wait – makes a wait for the specified seconds with mandatory milliseconds

  4. None of the statements are true
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Wait method in QTP/UFT (inherited from VBScript) accepts seconds as a required parameter and milliseconds as an optional parameter. The syntax is Wait(seconds, milliseconds), where milliseconds can be omitted. Option B incorrectly states milliseconds are not supported, while option C incorrectly states they are mandatory.

What is the method that can be used to retrive a run time value of any object, say a user input value?

  1. GetTOProperty

  2. SetTOProperty

  3. GetROProperty

  4. None
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

GetROProperty (Run-Time Object Property) is used to retrieve the actual runtime value of an object's property, such as user input or dynamically generated values. GetTOProperty retrieves test object properties (descriptive properties), while SetTOProperty modifies test object properties but doesn't affect runtime objects.

Recovery scenario takes us thru the following wizard steps in the following sequence

  1. define a trigger, define the recovery operations, define the post recovery operations

  2. define the recovery operations, define a trigger, define the post recovery operations

  3. can be created in any order

  4. no such wizard is available in Quick Test
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Recovery scenarios in QTP follow a fixed sequence: first define the trigger event that detects the error, then specify recovery operations to fix it, and finally define post-recovery operations. This wizard structure ensures systematic error handling.

Multiple choice technology

The approach/document used to make sure all the requirements are covered when writing test cases

  1. Test Matrix

  2. Checklist

  3. Test bed

  4. Traceablity Matrix
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A Traceability Matrix maps requirements to test cases to ensure all requirements are covered by testing. Test Matrix and Checklist are different (broader) concepts. Test bed refers to the test environment. Only Traceability Matrix specifically validates requirement coverage.

Multiple choice technology

------------- means under what test environment(Hardware, software set up) the application will run smoothly

  1. Test Bed

  2. Checkpoint

  3. Code Walk through

  4. Checklist
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A Test Bed (option A) is the configured environment including hardware, software, network, and data setup required to execute tests. It provides the infrastructure for running the application under test. A checkpoint is a verification point. Code walkthrough is a review technique. A checklist is a testing aid.

Multiple choice technology

How severely the bug is effecting the application is called as

  1. Severity

  2. Priority

  3. Fix ability

  4. Traceability
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Severity (option A) measures the technical impact of a bug on the application's functionality. Priority indicates how urgently the bug needs to be fixed based on business needs. Fix ability refers to how easily it can be resolved. Traceability tracks the bug's lifecycle.

What are the Testing Levels?

  1. Unit Testing

  2. Integration Testing

  3. System Testing and Acceptance Testing.

  4. All the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Testing levels include Unit Testing (individual components), Integration Testing (combined components), System Testing (complete system), and Acceptance Testing (user validation). Option D 'All the above' correctly captures that these are all testing levels in the hierarchy.

Multiple choice technology

Software testing which is done without planning and Documentation is known as

  1. adHoc Testing

  2. Unit Testing

  3. Regression testing

  4. Functional testing.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ad hoc Testing (option A) is informal testing done without planning, documentation, or formal test cases. It's exploratory and relies on the tester's intuition and experience. Unit testing is formal. Regression testing is planned. Functional testing follows requirements.

Multiple choice technology

A Non-Functional Software testing done to check if the user interface is easy to use and understand

  1. Usability Testing

  2. Security Testing

  3. Unit testing

  4. Block Box Testing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Usability testing is a non-functional testing type that evaluates how easy and intuitive a user interface is for end users. It checks if users can understand and navigate the interface effectively. Security testing focuses on vulnerabilities, unit testing tests individual code units, and black box testing examines functionality without seeing internal code.

Multiple choice technology

White box testing is not called as___________

  1. Glass box testing

  2. Closed box testing

  3. OPen box testing

  4. Clear box testing
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

White box testing is called glass box testing, open box testing, and clear box testing because the tester can see inside the code. It is NOT called 'closed box testing' - that term would refer to black box testing where you cannot see the internal code structure. Option B is the correct answer.

Multiple choice technology

The testing which is done by going thro' the code is known as,

  1. Unit Testing

  2. Blackbox testing

  3. White box Testing

  4. Regression testing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

White box testing involves examining and testing the internal code structure, logic, and implementation of a program. The tester has access to the source code and understands how the software works internally. Unit testing is a type of white box testing but more specific, black box testing doesn't look at code, and regression testing checks for unintended changes.

Multiple choice technology

This Testing Technique examines the basic program structure and it derives the test data from the program logic; Ensuring that all statements and conditions executed at least once. It is called as

  1. Block box Testing

  2. White box Testing

  3. Grey Box Testing

  4. Closed Box Testing
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

White box testing examines the program's internal structure, logic, and code to derive test cases. It ensures all statements and branches are executed at least once (statement and branch coverage). Black box testing doesn't look at code, gray box combines both approaches, and 'closed box' isn't a standard testing term (black box is the correct opposite of white box).
