Installability testing is usually conducted during which stage in the application's SDLC and usually includes which other types of testing?

Installability testing is usually conducted during the System Testing stage of the SDLC. It typically

includes testing the installation process of the software to verify that it installs correctly across

various systems and configurations. This type of testing often overlaps with functionality testing to

ensure all functions are available post-installation, and usability testing to ensure that the installation

process is intuitive and user-friendly.

Explanation: System testing encompasses a broad spectrum of testing practices intended to validate

the software in its entirety, ensuring it meets the specified requirements and is ready for operation.

Reference: According to the ISTQB CTAL-TTA materials, installability testing is part of system testing,

with a specific focus on the ease and correctness of the software installation process.
