--description--

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。

include() 和 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--

使用 assert.include() 或 assert.notInclude() 让测试通过。

--hints--

不应有未通过的测试

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=13').then(
    (data) => {
      assert.equal(data.state, 'passed');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

请选择正确的断言—include 或 notInclude

(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);
    }
  );

请选择正确的断言—include 或 notInclude

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=13').then(
    (data) => {
      assert.equal(
        data.assertions[1].method,
        'notInclude',
        "... a 'dart' doesn't contain a 'queue'"
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
