Description: Installation testing is a critical component in the software development lifecycle, designed to verify that the software installs correctly and functions as expected in the target environment. These tests ensure that all software components are properly copied to the system, that initial configurations are correctly performed, and that the software is accessible to the end user. Installation testing may include verifying installation on different operating systems, validating prerequisites, checking the functionality of updates, and uninstalling the software. Additionally, automated installation tests can be performed, allowing these processes to be executed efficiently and repeatably, reducing the risk of human error and speeding up software delivery time. The importance of these tests lies in the fact that a failed installation can lead to a negative user experience, affect product perception, and ultimately impact the reputation of the developing company. Therefore, installation testing is essential to ensure the quality and reliability of the software before its release.
