# 测试结果 (JSON) [JavaScript 对象表示法 (JSON)](http://www.json.org/)是轻量级的数据交换格式。下面的例子展示了 `ArrayTest` 中的测试所生成的 JSON 讯息： ~~~ {"event":"suiteStart","suite":"ArrayTest","tests":2} {"event":"test","suite":"ArrayTest", "test":"testNewArrayIsEmpty(ArrayTest)","status":"pass", "time":0.000460147858,"trace":[],"message":""} {"event":"test","suite":"ArrayTest", "test":"testArrayContainsAnElement(ArrayTest)","status":"pass", "time":0.000422954559,"trace":[],"message":""} ~~~ 以下 JSON 讯息是由名为 `FailureErrorTest` 的测试用例类中的两个测试 `testFailure` 和 `testError` 所生成的，展示了失败和错误是如何表示的： ~~~ {"event":"suiteStart","suite":"FailureErrorTest","tests":2} {"event":"test","suite":"FailureErrorTest", "test":"testFailure(FailureErrorTest)","status":"fail", "time":0.0082459449768066,"trace":[], "message":"Failed asserting that <integer:2> is equal to <integer:1>."} {"event":"test","suite":"FailureErrorTest", "test":"testError(FailureErrorTest)","status":"error", "time":0.0083680152893066,"trace":[],"message":""} ~~~
