äärearvutuslikke

Äärearvutuslikke, also known as boundary value analysis, is a software testing technique used to test the boundaries of input data. It is based on the idea that errors often occur at the edges of input ranges, rather than in the middle. This technique is particularly useful for identifying defects that may not be found through other testing methods.

Boundary value analysis involves selecting test cases that include the minimum and maximum values within the input range, as well as just outside these limits. This approach helps to ensure that the software behaves correctly at the boundaries of its input data. By testing these edge cases, testers can identify potential issues such as off-by-one errors, buffer overflows, and other boundary-related problems.

The process of boundary value analysis typically involves the following steps:

1. Identify the input variables and their valid ranges.

2. Determine the boundary values for each input variable, including the minimum, maximum, and just outside these limits.

3. Create test cases that include these boundary values.

4. Execute the test cases and observe the behavior of the software.

5. Analyze the results to identify any defects or issues that may have been missed by other testing methods.

Boundary value analysis is a valuable technique for improving the quality and reliability of software. By focusing on the boundaries of input data, testers can identify and fix defects that may not be apparent through other testing approaches. This technique is widely used in software development and testing, and is an essential tool for ensuring the robustness and reliability of software systems.
