Questions Related to testing

Incorrect form of Logic coverage is

technology testing

  1. Statement coverage

  2. Pole Coverage

  3. Condition Coverage

  4. Path Coverage

Show answer
Correct Option: B

AI Explanation

To answer this question, you need to understand the concept of logic coverage. Logic coverage is a measure of how well a test suite exercises the logic in a program or system. It helps to ensure that all logical conditions and paths are tested.

Let's go through each option to understand why it is correct or incorrect:

Option A) Statement coverage - This option is incorrect because statement coverage is a type of logic coverage. It measures the percentage of statements in the code that are executed by the test suite.

Option B) Pole Coverage - This option is correct. Pole coverage is not a valid form of logic coverage. It is not a recognized term or technique in software testing.

Option C) Condition coverage - This option is incorrect because condition coverage is a type of logic coverage. It measures the percentage of logical conditions in the code that are evaluated to both true and false during testing.

Option D) Path coverage - This option is incorrect because path coverage is a type of logic coverage. It measures the percentage of different paths through the code that are executed by the test suite.

The correct answer is B) Pole Coverage. This option is incorrect because pole coverage is not a valid form of logic coverage.

Which of the following is not a quality characteristic listed in ISO 9126 Standard?
technology testing

  1. Functionality

  2. Usability

  3. Supportability

  4. Maintainability

Show answer
Correct Option: C

To test a function, the programmer has to write a _________, which calls the function to be tested and passes it test data.

technology testing

  1. Stub

  2. Driver

  3. Proxy

  4. None of the above

Show answer
Correct Option: B
Explanation:

To solve this question, the user needs to know about software testing techniques, specifically unit testing. The user must identify the correct term for a program that calls a function with test data to test its functionality.

Now, let's go through each option and explain why it is right or wrong:

A. Stub: A stub is a piece of code that simulates the behavior of a function or module. It is used in place of the actual function or module during testing. While a stub can be used in testing, it is not the correct term for a program that calls a function with test data to test its functionality.

B. Driver: A driver is a program that calls a function with test data to test its functionality. It is used to test functions that rely on input from other functions or modules. This option is correct.

C. Proxy: A proxy is an intermediary between two systems that allows them to communicate with each other. It is not the correct term for a program that calls a function with test data to test its functionality.

D. None of the above: This option is incorrect because option B, Driver, is the correct answer.

The Answer is: B

Boundary value testing
technology testing

  1. Is the same as equivalence partitioning tests

  2. Test boundary conditions on, below and above the edges of input and output equivalence classes

  3. Tests combinations of input circumstances

  4. Is used in white box testing strategy

Show answer
Correct Option: B

Pick the best definition of quality
technology testing

  1. Quality is job one

  2. Zero defects

  3. Conformance to requirements

  4. Work as designed

Show answer
Correct Option: C

Fault Masking is

technology testing

  1. Error condition hiding another error condition

  2. Creating a test case which does not reveal a fault

  3. Masking a Fault by Developer

  4. Masking a Fault by tester

Show answer
Correct Option: A

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Error condition hiding another error condition - This option is correct. Fault masking refers to the situation where one error condition hides another error condition. This means that when one fault occurs, it masks or conceals the presence of another fault, making it difficult to identify and debug the system.

Option B) Creating a test case which does not reveal a fault - This option is not correct. Creating a test case that does not reveal a fault is known as fault masking prevention. It aims to ensure that test cases are designed to uncover faults rather than hide them.

Option C) Masking a Fault by Developer - This option is not correct. Fault masking is not related to masking a fault by a developer. It is a phenomenon that occurs during the execution of a system or software.

Option D) Masking a Fault by tester - This option is not correct. Fault masking is not related to masking a fault by a tester. It is a phenomenon that occurs during the execution of a system or software.

The correct answer is A) Error condition hiding another error condition. This option is correct because it accurately describes the concept of fault masking, which refers to the situation where one error condition hides another error condition.

One Key reason why developers have difficulty testing their own work is :
