What is the correct order of STLC phases?

Requirement Analysis → Test Planning → Test Design → Environment Setup → Test Execution → Test ClosureTest Planning → Requirement Analysis → Test Execution → Test Design → Test Closure → Environment SetupTest Design → Test Planning → Requirement Analysis → Test Execution → Environment Setup → Test ClosureRequirement Analysis → Test Execution → Test Planning → Test Closure → Test Design → Environment Setup

2

Which testing level verifies that individually tested modules work correctly when combined?

Unit TestingIntegration TestingSystem TestingAcceptance Testing

3

A company logo has a typo on a rarely visited 'About Us' page. How would you classify this?

High Severity, High PriorityHigh Severity, Low PriorityLow Severity, High PriorityLow Severity, Low Priority

4

Which of the following is NOT a standard component of a well-written test case?

PreconditionsExpected ResultSource code of the feature under testSteps to execute

5

What is the primary purpose of a Requirements Traceability Matrix (RTM)?

To track developer productivityTo ensure every requirement is covered by at least one test caseTo estimate the project budgetTo assign bugs to developers

6

An input field accepts ages 18–60. Using Equivalence Class Partitioning, which set of test values best covers all partitions?

18, 30, 6017, 35, 610, 25, 10015, 40, 65

7

What is the key difference between Smoke Testing and Sanity Testing?

Smoke testing is done after every bug fix; sanity testing is done on initial buildsSmoke testing verifies critical functionalities of a new build; sanity testing verifies specific fixes or functionality after changesThey are the same thing with different namesSmoke testing is automated; sanity testing is always manual

8

In Risk-Based Testing, which factor combination should be tested FIRST?

Low likelihood of failure, low business impactHigh likelihood of failure, low business impactHigh likelihood of failure, high business impactLow likelihood of failure, high business impact

9

In integration testing, what is the role of a 'stub'?

It replaces a module that calls the module under testIt replaces a module that is called by the module under testIt runs automated regression testsIt generates test data for the database

10

What does 'Regression Testing' primarily aim to verify?

That new features work as specifiedThat previously working functionality still works after changesThat the system meets performance benchmarksThat the UI matches the design mockups

11

Which technique uses a table of combinations of inputs to ensure all pairs of input parameters are tested?

Boundary Value AnalysisDecision Table TestingPairwise TestingState Transition Testing

12

What is the main goal of User Acceptance Testing (UAT)?

To find as many bugs as possible before releaseTo verify the system meets business requirements from the end user's perspectiveTo test the system under heavy loadTo check code coverage of unit tests

13

Which of the following best describes 'Boundary Value Analysis'?

Testing only the middle values of an input rangeTesting at the edges (minimum, maximum, just inside, just outside) of input rangesTesting all possible input combinationsTesting with random input values

14

What is the difference between Verification and Validation?

Verification checks the product is built correctly; Validation checks the right product is builtThey mean the same thing in software testingVerification is done by developers; Validation is done by managersVerification is dynamic testing; Validation is static testing

15

Which type of testing is performed WITHOUT knowledge of the internal code structure?

White-box TestingGrey-box TestingBlack-box TestingGlass-box Testing

16

What is a 'Test Harness'?

A document listing all test cases for a projectA collection of software and test data used to test a program unit by running it under varying conditionsA meeting where test results are reviewedA metric that measures code coverage percentage

17

When should testing activities ideally begin in the SDLC?

After development is completeDuring the requirements phaseOnly during the dedicated testing phaseAfter deployment to production

18

What does 'Defect Life Cycle' refer to?

The time it takes to fix a bugThe journey of a defect from discovery to closure through various statesThe number of bugs found per sprintThe process of writing test cases

19

Which metric indicates the percentage of requirements covered by test cases?

Code CoverageDefect DensityTest CoverageCyclomatic Complexity

20

What is 'Exploratory Testing'?

Testing performed strictly according to written test casesSimultaneous test design, execution, and learning, where the tester actively explores the applicationTesting only the main user flowsAutomated testing using scripts
