    strategies.addStrategies(JanusGraphStepStrategy.instance());
    for (final TraversalStrategy strategy : otherStrategies) {
        strategies.addStrategies(strategy);
    }
    // Can't add explicitly add JanusGraphVertexStep or JanusGraphMultiQueryStep to the expected traversal so add them now
    Traversal.Admin<?, ?> optimized = expected.asAdmin();
    applyMultiQueryTraversalSteps(optimized);
    original.asAdmin().setStrategies(strategies);
    original.asAdmin().applyStrategies();
    // Tried using assertEquals(optimized, original), but if the traversal has any steps of type SideEffectStep that fails
    assertEquals(optimized.toString(), original.toString());
