587d824d367417b2b2512c54 使用正则表达式测试字符串 2 301608 use-regular-expressions-to-test-a-string

--description--

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。

match() 断言一个值匹配一个正则表达式(第二个参数)。

--instructions--

tests/1_unit-tests.js 中,Strings 套件里标有 #15 的测试下,将每个 assert 改成 assert.matchassert.notMatch 方法,通过测试(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=14').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:matchnotMatch

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=14').then(
    (data) => {
      assert.equal(
        data.assertions[0].method,
        'match',
        "'# name:John Doe, age:35' matches the regex"
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

应该为第二个断言选择正确的方法:matchnotMatch

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=14').then(
    (data) => {
      assert.equal(
        data.assertions[1].method,
        'notMatch',
        "'# name:Paul Smith III, age:twenty-four' does not match the regex (the age must be numeric)"
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
