To execute the Vugen script from the command line, you can use the following command:

A) "LoadRunner install dir" \bin\mcmdrv.exe -usr "path to .usr file"

Explanation for each option:

A) "LoadRunner install dir" \bin\mcmdrv.exe -usr "path to .usr file" - This option is correct. It specifies the path to the Vugen script (.usr file) and uses the mcmdrv.exe executable to execute the script from the command line.

B) "LoadRunner install dir" \bin\mmdrv.exe -usr "path to .usr file" - This option is incorrect. The correct executable to execute the Vugen script from the command line is mcmdrv.exe, not mmdrv.exe.

C) "LoadRunner install dir" \bin\mrmdrv.exe -usr "path to .usr file" - This option is incorrect. The correct executable to execute the Vugen script from the command line is mcmdrv.exe, not mrmdrv.exe.

D) "LoadRunner install dir" \bin\mpmdrv.exe -usr "path to .usr file" - This option is incorrect. The correct executable to execute the Vugen script from the command line is mcmdrv.exe, not mpmdrv.exe.

Therefore, the correct answer is A) "LoadRunner install dir" \bin\mcmdrv.exe -usr "path to .usr file".

To answer this question, you need to understand black box testing and different design techniques used in software testing.

Black box testing is a testing technique where the internal workings of the system under test are not known to the tester. The tester focuses on the inputs and outputs of the system without considering its internal structure or implementation. Black box design techniques are used to define test cases for black box testing.

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

Option A) Statement testing - This option is incorrect because statement testing is a white box design technique. It involves testing individual statements or instructions in the code to ensure that they are executed correctly.

Option B) Equivalence partitioning - This option is correct because equivalence partitioning is a black box design technique. It involves dividing the input domain into equivalence classes and selecting test cases from each class to represent the entire input domain. This technique helps in reducing the number of test cases while still providing adequate coverage.

Option C) Error-guessing - This option is incorrect because error-guessing is not a specific design technique. It is a technique where testers use their experience and intuition to guess potential errors or issues in the system without following any specific design guidelines.

Option D) Usability testing - This option is incorrect because usability testing is not a design technique. It is a type of testing where the focus is on evaluating the system's user interface and user experience.

The correct answer is Option B) Equivalence partitioning. This option is correct because equivalence partitioning is a black box design technique used in black box testing.

To answer this question, we need to understand the concept of static testing.

Static testing is a software testing technique that involves reviewing and inspecting the software artifacts without executing the program. It is performed during the early stages of the software development life cycle to identify defects, improve quality, and ensure compliance with standards.

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

Option A) Code inspection - This option is correct. Code inspection is a static testing technique where the software code is reviewed manually to find defects, improve code quality, and ensure adherence to coding standards. It is a form of static testing because it does not involve executing the code.

Option B) Coverage analysis - This option is incorrect. Coverage analysis is a dynamic testing technique that measures the amount of code covered by test cases. It requires executing the program and analyzing the code coverage achieved.

Option C) Usability assessment - This option is incorrect. Usability assessment involves evaluating the software's user interface and user experience to determine how easy it is to use. It is a form of dynamic testing because it typically involves interacting with the software.

Option D) Installation test - This option is incorrect. Installation test is a type of dynamic testing that verifies the successful installation and configuration of the software. It involves executing the installation process and checking if the software functions correctly.

The correct answer is Option A) code inspection. This option is correct because code inspection is a static testing technique that involves reviewing the software code without executing it.

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

Option A) Volume testing - This option is incorrect because volume testing is focused on testing the system's ability to handle large amounts of data, not specifically measuring the response to demand.

Option B) Stress testing - This option is incorrect because stress testing is focused on testing the system's ability to handle extreme workloads, not specifically measuring the response to demand.

Option C) Load testing - This option is correct because load testing specifically involves putting demand on a system by simulating real-world user loads and measuring its response. It helps evaluate the system's performance under expected loads and identify any performance bottlenecks.

Option D) Performance testing - This option is incorrect because performance testing is a broader term that encompasses various types of testing, including load testing. While it may involve measuring the system's response, it does not specifically refer to putting demand on a system.

The correct answer is C) Load testing. This option is correct because load testing involves putting demand on a system and measuring its response.
