587d824b367417b2b2512c4b 用三個等號斷言嚴格相等 2 301610 use-the-triple-equals-to-assert-strict-equality

--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。

strictEqual() 使用 === 比較對象。

--instructions--

tests/1_unit-tests.js 中,在 Equality 套件裏標有 #6 的測試下,將每個 assert 改爲 assert.strictEqualassert.notStrictEqual,讓測試通過(應該返回 true)。 不要修改傳給斷言的參數。

--hints--

應通過所有測試。

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(
    (data) => {
      assert.equal(data.state, 'passed');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

應該爲第一個斷言選擇正確的方法:strictEqualnotStrictEqual

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(
    (data) => {
      assert.equal(
        data.assertions[0].method,
        'notStrictEqual',
        'with strictEqual the type must match'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

應該爲第二個斷言選擇正確的方法:strictEqualnotStrictEqual

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(
    (data) => {
      assert.equal(data.assertions[1].method, 'strictEqual', '3*2 = 6...');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

應該爲第三個斷言選擇正確的方法:strictEqualnotStrictEqual

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(
    (data) => {
      assert.equal(
        data.assertions[2].method,
        'strictEqual',
        "6 * '2' is 12. Types match !"
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

應該爲第四個斷言選擇正確的方法:strictEqualnotStrictEqual

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(
    (data) => {
      assert.equal(
        data.assertions[3].method,
        'notStrictEqual',
        'Even if they have the same elements, the Arrays are notStrictEqual'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
