the class StreamTaskTest method testBufferDebloatingMultiGates.

    IndexedInputGate[] gates = new IndexedInputGate[partitionIds.length];
    for (int gateIndex = 0; gateIndex < gates.length; ++gateIndex) {
        final InputGateDeploymentDescriptor gateDescriptor = createInputGateDeploymentDescriptor(senderLocation, gateIndex, location);

        gate.setup();
        gates[gateIndex] = gate;
    }
    if (gates.length > 1) {
