--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。

include()notInclude() 同样可以用于字符串。 include() 用于断言字符串中包含某个子字符串。

--instructions--

tests/1_unit-tests.js 中,Strings 套件里标有 #14 的测试下,将每个 assert 改成 assert.includeassert.notInclude 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=13').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:includenotInclude

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=13').then(
    (data) => {
      assert.equal(
        data.assertions[0].method,
        'include',
        "'Arrow' contains 'row'..."
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

    (data) => {

        'notInclude',
        "... a 'dart' doesn't contain a 'queue'"
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
