The main feature of QTP i.e., “testing only GUI” lead to the upgrade for a newer version of the software.
QTP contains very big tests, which lead to the consumption of more memory. Due to this, the CPU gets utilized for a longer time and this affects the system’s speed.
The results of scripts executed in QTP are saved as HTML files instead of text (.txt) files. With this, the size of the result files or group of files will occupy more system space.
