## Description
提醒一下,这个项目是基于Glitch的以下入门项目构建的,或者是从GitHub克隆的。 #include(在#notInclude上)也适用于字符串!!它断言实际的字符串包含预期的子字符串
## Instructions
## Tests
```yml
tests:
- text: 所有测试都应该通过
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: 选择正确的断言 - include与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: 选择正确的断言 - include与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); })'
