Which of the following statements is true regarding fault seeding and fault injection tools?
Fault seeding and fault injection tools are used intentionally to introduce defects into a system or software to test the robustness of the test suite. This method helps in validating the effectiveness of the test processes and configurations by ensuring that the tests are capable of detecting and isolating inserted faults. It is a technique used to measure the quality of testing rather than debugging or performance compliance, which relates directly to the fundamental purpose of enhancing test coverage and the detection capability of the test suite .
Which of the following can be executed by model-based testing tools?
Model-based testing tools are specifically designed to simulate and verify various computational models, including finite state machines (FSM). FSMs are a core part of model-based testing, allowing the definition of system behavior under different inputs and states. Model-based testing tools use these machines to ensure that all states and transitions are covered during testing, providing a systematic approach to test automation and validation.
Installability testing is usually conducted during which stage in the application's SDLC and usually includes which other types of testing?
Installability testing is usually conducted during the System Testing stage of the SDLC. It typically includes testing the installation process of the software to verify that it installs correctly across various systems and configurations. This type of testing often overlaps with functionality testing to ensure all functions are available post-installation, and usability testing to ensure that the installation process is intuitive and user-friendly.
You are responsible for planning the non-functional testing for a new product. You will be responsible for the performance testing and you have determined that you will need a simulator to complete your work, Which of the following are considerations when purchasing a simulator?
1. Path testing of the tool
2. Time to test the tool
3. cost of hmng specialists
4. Susceptibility to the "probe effect"
5. Method and bme to upgrade and retest the tool as the software changes
6. Control flow analysis
When purchasing a simulator for performance testing, considerations should include:
Time to test the tool -- How long it will take to validate the simulator itself.
Cost of hiring specialists -- The financial aspect of requiring specialized knowledge to operate or customize the simulator.
Method and time to upgrade and retest the tool as the software changes -- How the simulator can be kept up-to-date with the software it is meant to simulate and the effort involved in retesting it after updates.
These points focus on practical and economic aspects of using a simulator in testing environments.
Which of the following is a true statement regarding a continuous integration environment?
In a continuous integration environment, it's true that automation tools are used to verify the results of the build. This practice ensures that as new code integrations occur, they do not disrupt existing functionality and that all tests pass successfully before further deployments.
