ISTQB : The Human Psychology Of Testing! Trivia Quiz

Independence testing refers to the practice of testing software components or modules in isolation, without any dependencies on other components. This type of testing can be conducted at any level of testing, whether it is unit testing, integration testing, or system testing. By testing components independently, it helps to identify and isolate any issues or defects within the individual components, ensuring that they function correctly on their own before being integrated with other components. Therefore, the statement "Independence testing can be carried out at any level of testing" is true.

This is because failures are identified against the product and the work of the author.

Defects found and fixed during testing will save time and money by preventing the occurrence of errors in the future. This is because identifying and resolving defects early in the testing phase reduces the need for extensive debugging and rework later on. Additionally, addressing these defects helps in reducing the risk associated with the software or product, as it ensures that it functions correctly and meets the desired quality standards. Therefore, the correct answer is "time & risk".

They can but responsibility is usually given to the tester

Independence testing avoids author bias. This means that when conducting an independence test, the researcher ensures that their personal opinions, beliefs, or preferences do not influence the results or conclusions of the study. By avoiding bias, the researcher can maintain objectivity and increase the reliability and validity of the findings. This is important in scientific research as it allows for unbiased evaluation of relationships between variables and helps to establish accurate cause-and-effect relationships.

The mindset should be different

Identifying failures during testing may be perceived as a criticism against the author. This is because the author is responsible for creating and developing the product or system being tested. When failures are found, it can be seen as a reflection of the author's work and may be interpreted as a critique of their abilities or expertise.

Tests designed by a person from a different company/organization (outsourcing or certification by an external body) provide the highest level of independence. This is because an external entity is not directly involved in the development process and has no bias or vested interest in the outcome of the tests. They can provide an objective evaluation of the software's functionality, quality, and adherence to standards. This level of independence ensures a more thorough and unbiased assessment of the software's performance.

To effectively identify failures in a system, it is important to have a sense of pessimism, as this helps in anticipating potential issues and being proactive in finding them. Additionally, collaborating with peers is crucial as they can provide different perspectives and insights, contributing to a more thorough analysis. Error guessing is another valuable skill, as it involves thinking creatively about potential errors that may occur and actively seeking them out. By combining these attributes of pessimism, collaboration with peers, and error guessing, one can increase the chances of uncovering failures in a system.
