## 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。 .isAbove（）=> a> b，.isAtMost（）=> a <= b
## 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=7").then(data => {assert.equal(data.state,"passed"); }, xhr => { throw new Error(xhr.responseText); })'
- text: 选择正确的断言 - isAbove vs. isAtMost
testString: 'getUserInput => $.get(getUserInput("url") + "/_api/get-tests?type=unit&n=7").then(data => { assert.equal(data.assertions[0].method, "isAtMost", "5 is at most (<=) 5"); }, xhr => { throw new Error(xhr.responseText); })'
- text: 选择正确的断言 - isAbove vs. isAtMost
testString: 'getUserInput => $.get(getUserInput("url") + "/_api/get-tests?type=unit&n=7").then(data => { assert.equal(data.assertions[1].method, "isAbove", "1 is greater than 0"); }, xhr => { throw new Error(xhr.responseText); })'
- text: 选择正确的断言 - isAbove vs. isAtMost
testString: 'getUserInput => $.get(getUserInput("url") + "/_api/get-tests?type=unit&n=7").then(data => { assert.equal(data.assertions[2].method, "isAbove", "Math.PI = 3.14159265 is greater than 3"); }, xhr => { throw new Error(xhr.responseText); })'
- text: 选择正确的断言 - isAbove vs. isAtMost
testString: 'getUserInput => $.get(getUserInput("url") + "/_api/get-tests?type=unit&n=7").then(data => { assert.equal(data.assertions[3].method, "isAtMost", "1 - Math.random() is > 0 and <= 1. It is atMost 1 !"); }, xhr => { throw new Error(xhr.responseText); })'
