Software Testing and Quality Control Questions

Multiple choice technology testing

What is the testing done in OAT

  1. Non-functional(Excluding Performance Testing)

  2. Non Functional(Including Performance Testing)

  3. Functional

  4. All of the above

  5. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

OAT (Operational Acceptance Testing) performs non-functional testing such as security, usability, reliability, and compatibility testing, but excludes performance testing. Option A correctly describes this scope. Options B incorrectly includes performance testing, while C incorrectly suggests functional testing which is done in other phases.

Multiple choice technology testing

Which test activities are supported by test data preparation tool

  1. test management & control,

  2. test specifications & design,

  3. test execution & logging,

  4. performance & monitoring
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Test data preparation tools support the test specification and design phase by helping create, manage, and prepare the data sets needed for test scenarios. They are not used for test management/control (A), execution/logging (C), or performance monitoring (D), which are separate testing activities.

Multiple choice technology testing

Tools like change Man, Clear case are used as

  1. functional automation tools

  2. performance testing tools

  3. configuration management tools

  4. none of the above.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

ChangeMan and ClearCase are configuration management and version control tools used to track changes, manage versions, and control access to code and artifacts. They are not functional automation tools (A), performance testing tools (B), or unrelated to testing.

Multiple choice technology testing

The selection of test cases for regression testing

  1. Requires knowledge on the bug fixes and how it affect the system

  2. Includes the area of frequent defects

  3. Includes the area which has undergone many/recent code changes

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

Effective regression test selection requires multiple considerations: understanding how bug fixes impact system behavior (A), focusing on areas with historical defect patterns (B), and prioritizing recently changed code (C). All three factors are necessary for comprehensive regression coverage.

Multiple choice technology testing

We can achieve complete statement coverage but still miss bugs because:

  1. The failure occurs only if you reach a statement taking the TRUE branch of an IF statement, and you got to the statement with a test that passed through the FALSE branch.

  2. The failure depends on the program's inability to handle specific data values, rather than on the program's flow of control.

  3. Both A and B

  4. We are not required to test code that customers are unlikely to execute.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Complete statement coverage can miss bugs because some defects only occur under specific branch conditions (A), while others depend on data value handling rather than control flow (B). Both scenarios mean a bug can exist even when every statement is executed. Option D is a testing strategy, not a reason for coverage gaps.

Multiple choice technology testing

Typical defects that are easier to find in reviews than in dynamic testing are:

  1. deviations from standards,

  2. requirement defects,

  3. design defects,

  4. insufficient maintainability and incorrect interface specifications.

  5. All of the above.
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Static code reviews excel at finding non-runtime defects such as coding standard deviations, ambiguous requirements, flawed architecture/designs, poor maintainability, and interface mismatches before dynamic execution starts.

Multiple choice technology testing

What type of tests make up test set ?

  1. Smoke & Integration

  2. Smoke & Automated

  3. Integration & Manual

  4. Manual & Automated
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Test sets in Quality Center can contain both manual and automated tests, giving teams flexibility to group different test types together for execution cycles.

Multiple choice technology testing

What is a test set ?

  1. a folder of test result

  2. a folder of testing cycle

  3. a group of tests to achieve goal

  4. a group of test assigned to a release
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A test set is a logical collection of tests grouped to achieve a specific testing objective or goal, such as validating a feature or supporting a release cycle.

Multiple choice technology testing

What does the requirement tree define ?

  1. hierarchical relationship between requirement

  2. The number of test plan needed for each requirement

  3. Identify defects that are associated with each requirement

  4. Which release and or cycles are linked to each requirement
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The requirement tree defines the hierarchical structure and relationships between requirements, showing how parent and child requirements are organized.

Multiple choice technology testing

From which modules, one can log defect ?

  1. Defect

  2. Requirement & Defect

  3. Requirement, Test Plan, Defect

  4. Requirement, Test Plan, Test lab, Defect
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Defects can be logged from multiple modules - Requirements (during specification review), Test Plan (during test design), Test Lab (during test execution), and the Defect module itself.
