Which of the following is an example of self-checking code used as an oracle?

A function that calculates a checksum and verifies it after execution

What is the main purpose of executing a test case?

To determine if a system works as expected

You are testing a login feature that requires a username and password. Which test case is the most effective?

A combination of valid, invalid, empty, and boundary test cases

A comparison-based oracle is used to

Compare actual output with expected output

When using a comparison-based oracle, discrepancies between the actual and expected output indicate:

A potential defect in the software

Which of the following best describes a well-designed test case?

A test case with clear inputs, expected outputs, and execution steps

You are testing an online payment system. Which of the following is the best approach to designing test cases?

Include both valid and invalid scenarios in test cases

Self-checking code as an oracle helps in

Automating error detection by embedding checks in the software

In the context of software testing, what does "executing" a test case mean?

Performing specific actions to verify functionality

Which of the following best describes a test case?

A set of conditions to check software functionality

What is a test case primarily used for?

To verify a feature or functionality of software

Why is self-checking code useful in software testing?

It helps detect issues during runtime by verifying internal correctness

Answers

1
Which of the following is an example of self-checking code used as an oracle?
A code review process that identifies potential bugs
A test case that relies on manual inspection of output
Test case that compares software output with pre-recorded expected results
A function that calculates a checksum and verifies it after execution
2
What is the main purpose of executing a test case?
To create programming languages
To determine if a system works as expected
To develop computer hardware
To design new software
3
You are testing a login feature that requires a username and password. Which test case is the most effective?
A combination of valid, invalid, empty, and boundary test cases
Entering a valid username and password
Entering an empty username and password to check validation messages
Entering a correct username but an incorrect password
4
What typically happens when test cases are collected together?
They develop programming languages
They form test suites
They create new applications
They become software programs
5
A comparison-based oracle is used to
Analyze test results without requiring a reference output
Automatically generate test cases
Predict future failures in software
Compare actual output with expected output
6
When using a comparison-based oracle, discrepancies between the actual and expected output indicate:
The end of the testing cycle
A potential defect in the software
A failure in the testing process
The need to rewrite the test case
7
Which of the following best describes a well-designed test case?
A test case that covers all possible input values
Test case that tests the functionality without specifying expected results
A test case with clear inputs, expected outputs, and execution steps
A test case that only focuses on edge cases
8
How are test cases often referred to when they are written down?
Technical documents
Software manuals
Programming guides
Test scripts
9
You are testing an online payment system. Which of the following is the best approach to designing test cases?
Only test incorrect payment details
Include both valid and invalid scenarios in test cases
Only test valid credit card numbers
Skip payment gateway testing and focus on UI elements
10
Self-checking code as an oracle helps in
Manually verifying test results
Comparing software outputs with external benchmark datasets
Generating test cases dynamically
Automating error detection by embedding checks in the software
11
In the context of software testing, what does "executing" a test case mean?
Designing computer hardware
Creating programming languages
Writing new software code
Performing specific actions to verify functionality
12
Which of the following best describes a test case?
A set of conditions to check software functionality
A method of coding software
A set of random actions
A complex mathematical formula
13
What is a test case primarily used for?
To write test scripts
To create software applications
To develop new programming languages
To verify a feature or functionality of software
14
A banking application allows users to transfer money. Which of the following test scenarios should be included?
Transferring an amount larger than the account balance
Transferring $0 to another account
All of the above
Transferring to an invalid account number
15
Why is self-checking code useful in software testing?
It prevents all possible software failures
It guarantees that no bugs exist in the software
It helps detect issues during runtime by verifying internal correctness
It eliminates the need for human testers
