请注意，本项目在这个 Replit 项目的基础上进行开发。你也可以从 GitHub 上克隆。

--instructions--

在 tests/1_unit-tests.js 中，在 Comparisons 套件里标有 #9 的测试中，将每个 assert 改成 assert.isBelow 或 assert.isAtLeast 方法，让测试通过（结果应该返回 true）。不要修改传给断言的参数。

--hints--

应通过所有测试。

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

应该为第一个断言选择正确的方法：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);
    }
  );

应该为第二个断言选择正确的方法：isBelow 或 isAtLeast。

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=8').then(
    (data) => {
      assert.equal(
        data.assertions[1].method,
        'isAtLeast',
        '2 * Math.random() is at least 0'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

应该为第三个断言选择正确的方法：isBelow 或 isAtLeast。

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=8').then(
    (data) => {
      assert.equal(data.assertions[2].method, 'isBelow', '1 is smaller than 2');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

应该为第四个断言选择正确的方法：isBelow 或 isAtLeast。

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=8').then(
    (data) => {
      assert.equal(
        data.assertions[3].method,
        'isBelow',
        '2/3 (0.6666) is smaller than 1'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
