What factors should be considered to determine whether enough testing has been performed?
(i) The exit criteria.
(ii) The budget.
(iii) How big the test team is.
(iv) The product's risk profile.
(v) How good the testing tools are.
(vi) Sufficient details of the system status to allow decisions
Determining whether enough testing has been performed involves considering several factors. These include:
(i) The exit criteria, which define the conditions that must be met to conclude testing. (ii) The budget, which affects the extent of testing that can be conducted. (iv) The product's risk profile, which helps prioritize testing efforts on high-risk areas. (vi) Sufficient details of the system status to allow decisions, ensuring that stakeholders have the necessary information to make informed decisions about the software's readiness.
These factors together ensure a balanced and informed decision-making process regarding the sufficiency of testing.
Which statement is most true?
Different types of applications require different testing approaches based on their specific characteristics, risk profiles, and operational environments. For example, testing a financial application would focus heavily on security and accuracy, while testing a mobile game might focus more on performance and usability. The context-driven nature of software testing recognizes that there is no one-size-fits-all approach, and effective testing must be tailored to the particular application under test.
The purpose of exit criteria is:
Exit criteria are defined to determine when a specific testing activity or the entire testing process should be considered complete. This includes setting conditions such as when to stop testing, the end of a test level, and when certain pre-defined conditions or coverage levels have been achieved. Exit criteria help ensure that testing is systematic and meets the project's quality standards before moving on to the next phase or release.
Which of the following is a white-box test technique?
Statement testing is a white-box test technique that involves creating test cases to execute specific statements in the code. The goal is to ensure that all statements in the program are executed at least once during testing. This technique requires knowledge of the internal structure of the code and focuses on verifying the flow of execution and logic within the program.
An iPhone application identifies and counts all purchases of a particular product from a shopping website. The application incorrectly counts purchase attempts by including both failed attempts, and also those where the purchase was terminated by the user before completion. Testing has identified that the problem was located in the 'purchase identification' module, where the first stage in the purchasing process was counted, rather than a successful confirmed purchase.
Which of the following statements correctly identifies what has happened? [K2]
The application failed due to a defect in the purchase identification module. This defect could have been caused by a programmer mistake or an error in the specification. The incorrect counting of purchase attempts indicates a flaw in the logic or implementation of the module responsible for identifying successful purchases.
