--description--

请注意，本项目在 这个 Repl.it 项目 的基础上进行开发。你也可以从 GitHub 上克隆。

--instructions--

Use assert.isBelow() (i.e. less than) or assert.isAtLeast() (i.e. greater than or equal) to make the tests pass.

使用 assert.isBelow()（小于）或 assert.isAtLeast()（大于等于）让所有测试通过。

--hints--

不应有未通过的测试

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=8').then(
    (data) => {
      assert.equal(data.state, 'passed');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

请选择正确的断言—isBelow 或 isAtLeast

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=8').then(
    (data) => {
      assert.equal(
        data.assertions[0].method,
        'isAtLeast',
        '5 is at least (>=) 5'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
