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。

Tests

tests:
  - text: 不应有未通过的测试
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=13').then(data => { assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—include 或 notInclude
    testString: 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); })
  - text: 请选择正确的断言—include 或 notInclude
    testString: 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); })
