Building an enterprise-grade REST Assured framework requires strict decoupling of endpoint specifications, authentication providers, request specs, and reporting listeners.

// REST Assured Spec Builder Pattern
given()
    .spec(requestSpec)
    .auth().oauth2(bearerToken)
    .body(authPayload)
.when()
    .post(/api/v1/auth/login)
.then()
    .statusCode(200)
    .body(status, equalTo(SUCCESS))
    .body(user.role, equalTo(SDET_LEAD));
