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。

在 tests/1_unit-tests.js 中，在标有 #8 的 Comparisons 套件里，将每个 assert 改成 assert.isAbove 或 assert.isAtMost 方法，让测试通过（结果应该返回 true）。不要改变传入断言的参数。

不应有未通过的测试

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(
    (data) => {
      assert.equal(data.state, 'passed');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

请为第一个断言选择正确的方法 — isAbove 或 isAtMost。

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(
    (data) => {
      assert.equal(
        data.assertions[0].method,
        'isAtMost',
        '5 is at most (<=) 5'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

请为第二个断言选择正确的方法 — isAbove 或 isAtMost。

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(
    (data) => {
      assert.equal(data.assertions[1].method, 'isAbove', '1 is greater than 0');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

请为第三个断言选择正确的方法 — isAbove 或 isAtMost。

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(
    (data) => {
      assert.equal(
        data.assertions[2].method,
        'isAbove',
        'Math.PI = 3.14159265 is greater than 3'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

请为第四个断言选择正确的方法 — isAbove 或 isAtMost。

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(
    (data) => {
      assert.equal(
        data.assertions[3].method,
        'isAtMost',
        '1 - Math.random() is > 0 and <= 1. It is atMost 1 !'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
