tests:
  - text: 所有测试都应该通过
    testString: 'getUserInput => $.get(getUserInput("url") + "/_api/get-tests?type=unit&n=9").then(data => {assert.equal(data.state,"passed"); }, xhr => { throw new Error(xhr.responseText); })'
  - text: 使用大约（实际，预期，范围） - 选择正确的范围
    testString: 'getUserInput => $.get(getUserInput("url") + "/_api/get-tests?type=unit&n=9").then(data => {  assert.equal(data.assertions[0].method, "approximately");  assert.equal(data.assertions[0].args[2], 0.5, "weirdNumbers(0.5) is in the range (0.5, 1.5]. It\"s within 1 +/- 0.5"); }, xhr => { throw new Error(xhr.responseText); })'
  - text: 使用大约（实际，预期，范围） - 选择正确的范围
