We can also specify custom cookie to our request using cookie(): @Test public void whenUseCookie_thenOK() { given().cookie("session_id", "1234").when().get("/users/eugenp") .then().statusCode(200); } We can also customize our cookie using cookie Builder: Returns the value of the specified request header as an int. We generally use cookies in web application to store information and we are well aware how to do this in server side code. Any ideas on this.
