Testers select an exploit, configure a payload, and run it against a target they have permission to test. The framework includes scanners and post-exploitation modules. Rapid7 maintains it.
A free community edition exists, and Metasploit Pro adds features.
Cobalt Strike and Burp Suite serve other test needs. Metasploit suits penetration testers.
