Pre-Conditions specify the condition which needs conditions that need to be fulfilled in order to execute a test.

 A Pre-Condition is like defining the step "0" for your tests. This is very useful on in many use cases where you have to start by doing exactly the same thing (e.g. . For example, if you are going to do something in on a system, you most probably you have to authenticate first, right? ). But sometimes, you have to do several things  (e.g., restore DB, authenticate) before going through your Test steps. And each of those things may be used independentely (done and used independently, i.e.g. , some Test Tests may require just to restore restoring the DB, another may require just to authenticateauthentication, and others may require that both things , or even more, need to be done before starting executing the steps).
