4 Installation

4.1  General Information

The two main interfaces for running tests with Common Test are an executable program named ct_run and the Erlang module ct. ct_run is compiled for the underlying operating system (for example, Unix/Linux or Windows) during the build of the Erlang/OTP system, and is installed automatically with other executable programs in the top level bin directory of Erlang/OTP. The ct interface functions can be called from the Erlang shell, or from any Erlang function, on any supported platform.

The Common Test application is installed with the Erlang/OTP system. No extra installation step is required to start using Common Test through the ct_run executable program, and/or the interface functions in the ct module.
