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。 isString 或 isNotString 断言一个值是否为字符串。

Instructions

使用 assert.isString() 或 assert.isNotString() 让所有测试通过。

Tests

tests:
  - text: 不应有未通过的测试
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=12').then(data => { assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—isString 或 isNotString
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=12').then(data => {  assert.equal(data.assertions[0].method, 'isNotString', 'A float number is not a string'); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—isString 或 isNotString
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=12').then(data => {  assert.equal(data.assertions[1].method, 'isString', 'environment vars are strings (or undefined)'); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—isString 或 isNotString
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=12').then(data => {  assert.equal(data.assertions[2].method, 'isString', 'A JSON is a string'); }, xhr => { throw new Error(xhr.responseText); })
