Additional information

Test is failling with mvn test command, nevertheless when when we run mvn quarkus:dev`, GreetingTest fails the first time ans it passes when you hit the [r] to re-run the test.

Furhtermore, to make the the test pass with the mvn test command the following code works:

package org.acme.rest

import io.quarkus.test.junit.QuarkusTest
import io.restassured.RestAssured.given
import org.hamcrest.CoreMatchers.`is`
import org.junit.jupiter.api.Test

@QuarkusTest
class GreetingResourceTest {

    @Test
    fun testHelloEndpoint() {
        given()
          .`when`().get("/greeting")
          .then()
             .statusCode(200)
             .body(`is`("{\"message\":\"hello\"}"))
    }

}
