如何测试具有随机值属性的对象?

How can I test an object with properties with random values?

我正在编写一个单元测试,我正在模拟一个对象(客户端),它有一个需要一个对象和一个回调函数的 _request 方法。对象参数有几个具有随机值的属性:

var clientMock = sandbox.mock(client);   // client is defined up somewhere
clientMock
  .expects('_request')
  .withArgs({
    method: 'POST',
    form: {
      commands: [{
        type: "item_add",
        temp_id: '???',       // <== This is random value
        uuid: '???',          // <== Another random value
        args: { ... }
      }]
    }
  }, sinon.match.func);

如何设置测试?

或者我如何忽略那些特定属性并测试其他属性?

谢谢。

sinon.match will help you

sandbox.mock(client)
  .expects('_request')
  .withArgs({
    method: 'POST',
    form: {
      commands: [{
        type: "item_add",
        temp_id: sinon.match.string, // As you probably passing String
        uuid: sinon.match.string,    // As you probably passing String
        args: { ... }
      }]
    }
  }, sinon.match.func);

================

  sandbox.mock(client)
    .expects('_request')
    .withArgs(sinon.match(function(obj) {
      var command = obj.form.commands[0];
      return obj.method === 'POST'
        && command.type === 'item_add'
        && _.isString(command.temp_id)
        && _.isString(command.uuid);
      }, "Not the same!"), sinon.match.func);
