1.xunit格式

avocado run sleeptest.py failtest.py synctest.py --xunit -
<?xml version="1.0" encoding="UTF-8"?>
<testsuite name="avocado" tests="3" errors="0" failures="1" skipped="0" time="3.5769162178" timestamp="2016-05-04 14:46:52.803365">

        <testcase classname="FailTest" name="2-failtest.py:FailTest.test" time="0.00120401382446">
                <failure type="TestFail" message="This test is supposed to fail"><![CDATA[Traceback (most recent call last):

        </testcase>
        <testcase classname="SyncTest" name="3-synctest.py:SyncTest.test" time="2.57366299629"/>
</testsuite>

2.JSON格式

$ avocado run sleeptest.py failtest.py synctest.py --json -
{
    "cancel": 0,
    "debuglog": "/home/cleber/avocado/job-results/job-2016-08-09T13.53-10715c4/job.log",
    "errors": 0,
    "failures": 1,
    "job_id": "10715c4645d2d2b57889d7a4317fcd01451b600e",
    "pass": 2,

    "tests": [

            "logfile": "/home/cleber/avocado/job-results/job-2016-08-09T13.53-10715c4/test-results/1-sleeptest.py:SleepTest.test/debug.log",
            "start": 1470761622.174918,
            "status": "PASS",
            "id": "1-sleeptest.py:SleepTest.test",
            "time": 1.0020360946655273,
            "whiteboard": ""
        },
        {
            "end": 1470761623.193472,
            "fail_reason": "This test is supposed to fail",
            "logdir": "/home/cleber/avocado/job-results/job-2016-08-09T13.53-10715c4/test-results/2-failtest.py:FailTest.test",
            "logfile": "/home/cleber/avocado/job-results/job-2016-08-09T13.53-10715c4/test-results/2-failtest.py:FailTest.test/debug.log",

            "status": "FAIL",
            "id": "2-failtest.py:FailTest.test",
            "time": 0.0011379718780517578,
            "whiteboard": ""
        },
        {
            "end": 1470761625.656061,
            "fail_reason": "None",
            "logdir": "/home/cleber/avocado/job-results/job-2016-08-09T13.53-10715c4/test-results/3-synctest.py:SyncTest.test",

            "time": 2.4478960037231445,
            "whiteboard": ""
        }
    ],
    "time": 3.4510700702667236,
    "total": 3
}

3.TAP

$ avocado run sleeptest.py --tap -
1..1
# debug.log of sleeptest.py:SleepTest.test:
#   12:04:38 DEBUG| PARAMS (key=sleep_length, path=*, default=1) => 1
#   12:04:38 DEBUG| Sleeping for 1.00 seconds
#   12:04:39 INFO | PASS 1-sleeptest.py:SleepTest.test
#   12:04:39 INFO |
ok 1 sleeptest.py:SleepTest.test

4.无声结果

此结果禁用所有stdout日志记录（同时保持错误消息打印到stderr）。然后可以使用返回码来了解结果：

$ avocado --silent run failtest.py
$ echo $?
1

5.多个输出格式的结果

$ avocado run sleeptest.py synctest.py --xunit - --json /tmp/result.json
<?xml version="1.0" encoding="UTF-8"?>
<testsuite name="avocado" tests="2" errors="0" failures="0" skipped="0" time="3.64848303795" timestamp="2016-05-04 17:26:05.645665">
        <testcase classname="SleepTest" name="1-sleeptest.py:SleepTest.test" time="1.00270605087"/>
        <testcase classname="SyncTest" name="2-synctest.py:SyncTest.test" time="2.64577698708"/>
</testsuite>

$ cat /tmp/result.json
{
     "debuglog": "/home/cleber/avocado/job-results/job-2016-08-09T13.55-1a94ad6/job.log",
     "errors": 0,
     ...
}
