# Interview

For the JT harness to execute a test suite, it requires information about how your computing environment is configured. The Configuration Editor uses an interview to simplify the process of collecting this information.

Because the quantity and scope of this information depends on the test suite, a test suite might include a specific interview for the Configuration Editor to use.

The information collected by the interview is written to a configuration file (`.jti`) and used by the JT harness to derive the environment variables required execute the test suite.
