A capacity test identifies how many concurrent users (people using an application at the same time) an application can handle before "breaking."

This type of test is most often associated with capacity planning, determining the architecture of the application, including the number of servers, their memory size, and the speed of the servers based on business needs.

Usually a "capacity test" refers to the total number of users an architecture can support under normal operating conditions. Similar to load tests, which often test more specific user activity, a capacity test aims to identify the total number of users an application can support.
