Black box testing and white box testing

What is boundary value testing?

• Boundary value testing is a software testing technique focusing on the middle values of input ranges.

• Boundary value testing is a software testing technique focusing on the performance of the software.

• Boundary value testing is a software testing technique focusing on the output of the software.

• Boundary value testing is a software testing technique focusing on the boundary conditions of input ranges.

Explain equivalence partitioning.

• Equivalence partitioning is a testing technique where input data is divided into partitions based on the color of the input.

• Equivalence partitioning is a testing technique where input data is divided into partitions based on alphabetical order.

• Equivalence partitioning is a testing technique where input data is divided into partitions based on the length of the input.

• Equivalence partitioning is a testing technique where input data is divided into partitions or classes that are considered equivalent. Test cases are designed to cover each partition at least once.

What is black box testing?

• Black box testing is a method that focuses on code optimization.

• Black box testing is a method where the tester knows the internal structure of the software.

• Black box testing is only applicable to hardware testing.

• Black box testing is a software testing method where the internal structure/design/implementation of the item being tested is not known to the tester.

Describe white box testing.

• White box testing is a software testing method where the internal structure, design, and implementation of the system are known and used to devise test cases.

• White box testing is a type of performance testing

• White box testing focuses on testing the system without any knowledge of its internal structure

• White box testing is a method where only the user interface is tested

Why is boundary value testing important in software testing?

• Boundary value testing is irrelevant in software testing.

• Boundary value testing helps identify errors or defects at the boundaries of input ranges.

• Boundary value testing does not help in identifying defects.

• Boundary value testing only focuses on the middle values of input ranges.

How is equivalence partitioning used in test case design?

• Equivalence partitioning is used to test only the boundary values of the input domain.

• Equivalence partitioning is used to combine all input data into a single test case.

• Equivalence partitioning is used to divide the input domain into classes of data from which test cases can be derived.

• Equivalence partitioning is used to randomly select test cases from the input domain.

What are the advantages of black box testing?

• Advantages of white box testing

• Advantages of black box testing include unbiased testing, simulating end-user perspective, and effective in finding interface errors.

• Dependent on internal code structure

• Limited test coverage

What are the disadvantages of white box testing?

• Time-consuming, expensive, biased testing

• Limited, inefficient, objective

• Ineffective, unreliable, slow

• Quick, accurate, unbiased

Give an example of boundary value testing in a real-world scenario.

• Testing withdrawal amounts of $10, $11, $999, and $1000 in a banking system.

• Testing the login functionality of a social media platform

• Testing the font size options in a word processing software

• Testing the search bar functionality on an e-commerce website

How can white box testing help in identifying code vulnerabilities?

• By ignoring test coverage metrics

• By skipping code review processes

• By analyzing the internal structure of the code, including code paths, logic, and data flows, white box testing can help in identifying code vulnerabilities.

• By only focusing on the user interface
