    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=0').then(data => {assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
  - text: 选择正确的断言 -  isNull vs. isNotNull
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=0').then(data => {  assert.equal(data.assertions[0].method, 'isNull', 'Null is null'); }, xhr => { throw new Error(xhr.responseText); })
