Description: Loop testing is a testing technique focused on validating the behavior of loops in code. These tests are essential to ensure that loops, which are fundamental control structures in programming, function correctly under various conditions. A loop can be a ‘for’, ‘while’, or ‘do-while’, and its proper functioning is crucial, as an error in a loop can lead to unexpected results, such as infinite loops or incorrect calculations. Loop testing focuses on evaluating different scenarios, such as executing the loop zero, one, multiple, or many times, as well as verifying upper and lower boundaries. This technique not only helps identify logical errors but also ensures that the performance of the code is optimal. In the context of test-driven development (TDD), loop testing is an integral part of the process, as it allows developers to write tests before implementing the loop logic, ensuring that the code meets requirements from the outset. In summary, loop testing is a vital tool for maintaining software quality and reliability, especially in applications where loops are used extensively.
