Testisekvenssejä

Testisekvenssejä, often translated as test sequences, are a fundamental concept in software development and quality assurance. They represent a series of steps or actions that are performed to verify the correct functionality of a software system or a specific feature. These sequences are designed to exercise the software under various conditions, aiming to uncover defects or regressions.

The creation of test sequences typically begins with an understanding of the software's requirements and expected behavior. Test designers then translate these requirements into a logical flow of operations that a user or another system would perform. Each step in a test sequence should be clearly defined, specifying the input, the action to be taken, and the expected outcome. This ensures that the test can be executed consistently and objectively.

Test sequences can be executed manually by human testers or automated using specialized testing tools. Automated test sequences offer significant advantages in terms of speed, repeatability, and the ability to perform tests frequently, such as during continuous integration. Regardless of the execution method, the results of each test sequence are recorded, and any deviations from the expected outcome are reported as defects for further investigation and resolution.

The purpose of test sequences is to provide confidence in the quality and reliability of the software. By systematically checking different aspects of the system, test sequences help ensure that the software behaves as intended and meets the needs of its users. They are an integral part of the software development lifecycle, contributing to the delivery of robust and high-quality products.
