示例1: traversalEqual

function traversalEqual(node, expectedTraversal) {
  let actualTraversal = [];

  traverse(node, {
    All: {
      enter(node) { actualTraversal.push(['enter', node]); },
      exit(node) { actualTraversal.push(['exit',  node]); }
    }
  });

  QUnit.assert.deepEqual(
    actualTraversal.map(a => `${a[0]} ${a[1].type}`),
    expectedTraversal.map(a => `${a[0]} ${a[1].type}`)
  );

  let nodesEqual = true;

  for (let i = 0; i < actualTraversal.length; i++) {
    if (actualTraversal[i][1] !== expectedTraversal[i][1]) {
      nodesEqual = false;
      break;
    }
  }

  QUnit.assert.ok(nodesEqual, "Actual nodes match expected nodes");
