--description--

請注意,本項目在這個 Replit 項目的基礎上進行開發。你也可以從 GitHub 上克隆。

--instructions--

tests/1_unit-tests.js 中,在標有 #8Comparisons 套件裏,將每個 assert 改成 assert.isAboveassert.isAtMost 方法,讓測試通過(結果應該返回 true)。 不要改變傳入斷言的參數。

--hints--

不應有未通過的測試

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

請爲第一個斷言選擇正確的方法 — isAboveisAtMost

(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);
    }
  );

請爲第二個斷言選擇正確的方法 — isAboveisAtMost

(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);
    }
  );

請爲第三個斷言選擇正確的方法 — isAboveisAtMost

(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);
    }
  );

請爲第四個斷言選擇正確的方法 — isAboveisAtMost

(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);
    }
  );
