Test for play controller with custom application.conf

I trying make simple controller test in play framework

public class AuthTest extends WithServer {

@Test
public void authByLoginErrorForm() {
    Map<String,String> data = new HashMap<>();
    data.put("username", "");
    data.put("password", "");

    Result result = routeAndCall(fakeRequest("POST", "/auth_by_login"), Helpers.DEFAULT_TIMEOUT);
    assertEquals(400, result.status());
}
}

In builds.sbt i set custom conf for test mode. He need for exclude creation db pool connection in test.

javaOptions in Test ++= Seq(
"-Dlogger.file=test/conf/logback.xml",
"-Xms512M",
"-Xmx1536M",
"-XX:MaxPermSize=384M",
"-XX:MaxMetaspaceSize=384M",
"-Dconfig.file=test/conf/application.conf"
)

After test running i getting error:
