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。

Instructions

使用 assert.isAbove()（大于）或者 assert.isAtMost()（小于或等于）来让测试通过。

Tests

tests:
  - text: 不应有未通过的测试
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=7').then(data => {assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—isAbove 或 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: 请选择正确的断言—isAbove 或 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: 请选择正确的断言—isAbove 或 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: 请选择正确的断言—isAbove 或 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); })
