Query parameters are a way to pass information to an API flexibly and simply. They are added to the end of the API endpoint URL as a series of key-value pairs. To append query params to the end of a URL, a ‘?’ Is added followed immediately by a query parameter.
Query Param Example
https://reqres.in/api/users?page=2
Below is an example of Query Param.
import org.junit.Test;
import static io.restassured.RestAssured.given;
import static org.hamcrest.CoreMatchers.equalTo;
public class ParamDemo {
@Test
public void verifyQueryParam() {
String endpoint = "https://reqres.in/api/";
// Given
given()
.queryParam("page", "2")
// When
.when()
.get(endpoint + "users/")
// Then
.then()
// To verify the response body
.body("page", equalTo(2))
.body("per_page", equalTo(6))
.body("total_pages", equalTo(2));
}
}
The output of the above program is
.param() or queryParam(): If you don’t specify which, REST Assured will assume GET params are query params and POST params are form params.
