直接推荐吧，这两篇帖子一篇讲原理，一篇讲应用，仔细看能解决。

本篇就分享下使用，以及一个小坑
背景：
python CGI + httpd, 自己写了个调用robot api的class，然后运行 robot Framework的testcase
from robot import run
from Demo.utils.robotframework.robotframeworkmylistener import MyListener //替换成自己的
from Demo.utils.log.fatplogger import *
class RobotRunner:
def runTestcaseAndInsertToMySQL(self, testLogID, jobTestcaseFolderPath, db):
"""method to run test case and insert log to MySQL
@param (str) test_log_id
@param (str) jobTestcaseFolderPath
@return projectID
"""
try:
run(jobTestcaseFolderPath, listener=MyListener(testLogID, db), log=None)
except:
mylogger.info('Exception: Run testcase failed!')
from Demo.utils.db.dbinit import *
from Demo.utils.log.fatplogger import *
class MyListener(object):
ROBOT_LISTENER_API_VERSION = 2
stepCount = 0
testLogID = None
db = None
ms = None
def __init__(self, testLogID, db):
self.testLogID = testLogID
self.db = InitMySql()
t = time.time()
self.ms = int(round(t))
mylogger.info('init robot framework listener...')
def start_suite(self, name, args):
self.stepCount = self.stepCount + 1
log = "Starting Suite : " + name + " " + args['source']
self.insert_log(self.testLogID, self.stepCount, log)
def start_test(self, name, args):
self.stepCount = self.stepCount + 1
log = "Starting test : " + name
self.insert_log(self.testLogID, self.stepCount, log)
def end_test(self, name, args):
self.stepCount = self.stepCount + 1
log = "Ending Test: " + args['longname']
self.insert_log(self.testLogID, self.stepCount, log)
self.stepCount = self.stepCount + 1
log = "Test Result is : " + args['status']
self.insert_log(self.testLogID, self.stepCount, log)
if('PASS' in log):
self.tablename = 'testcase_log'
self.key = 'result_status = 1'
self.where = {"test_log_id": self.testLogID}
self.db.update(self.tablename, self.key, self.where)
self.stepCount = self.stepCount + 1
log = "Test Time is: " + str(args['elapsedtime'])
self.insert_log(self.testLogID, self.stepCount, log)
def log_message(self, message):
mylogger.info(self.stepCount)
self.stepCount = self.stepCount + 1
log = message['timestamp'] + " : " + message['level'] + " : " + message['message']
self.insert_log(self.testLogID, self.stepCount, log)
def insert_log(self, testLogID, stepCount, log):
self.tablename = 'testcase_log_detail'
self.key = 'test_log_id,log_step_number,log_info,createTime'
log = str(log).replace('\'', '\\\'')
self.keyValue = "('" + str(testLogID) + "','" + str(stepCount) + "', '"+ log + "', '"+ str(self.ms) + "')"
self.db.insert(self.tablename, self.key, self.keyValue)
这里MyListener中，我加入了 DB的操作，获取log后直接存到数据库里面
坑：
本地运行都可以，一上linux 就废了，各种过不了，最后发现是 存储output.xml的那个文件夹没有权限，chmod 就搞定了
debug的经历，
由于要在server 中，python site-packages 里面debug，看看为什么不行，没有什么好办法，只能打log。这里如果哪位大神有好的办法，求介绍
首先，找到robot 的位置，我的是 /usr/lib/python2.7/site-packages/robot
然后，先在本地debug，看看
run(jobTestcaseFolderPath, listener=MyListener(testLogID, db), log=None)
的大体实现。
直接贴过程：
step 1：
/usr/lib/python2.7/site-packages/robot/run.py
def main(self, datasources, **options):
settings = RobotSettings(options)
LOGGER.register_console_logger(**settings.console_output_config)
LOGGER.info('Settings:\n%s' % unic(settings))
suite = TestSuiteBuilder(settings['SuiteNames'],
settings['WarnOnSkipped'],
settings['Extension']).build(*datasources)
suite.configure(**settings.suite_config)
if settings.pre_run_modifiers:
suite.visit(ModelModifier(settings.pre_run_modifiers,
settings.run_empty_suite, LOGGER))
with pyloggingconf.robot_handler_enabled(settings.log_level):
result = suite.run(settings) -------------------这一行运行测试用例
LOGGER.info("Tests execution ended. Statistics:\n%s"
% result.suite.stat_message)
if settings.log or settings.report or settings.xunit:
writer = ResultWriter(settings.output if settings.log
else result)
writer.write_results(settings.get_rebot_settings())
return result.return_code
step 2：
/usr/lib/python2.7/site-packages/robot/running/model.py
def run(self, settings=None, **options):
from .namespace import IMPORTER
from .signalhandler import STOP_SIGNAL_MONITOR
from .runner import Runner
with LOGGER:
if not settings:
settings = RobotSettings(options)
LOGGER.register_console_logger(**settings.console_output_config)
with pyloggingconf.robot_handler_enabled(settings.log_level):
with STOP_SIGNAL_MONITOR:
IMPORTER.reset()
output = Output(settings) ----------------------进入这一步
runner = Runner(output, settings)
self.visit(runner)
output.close(runner.result)
return runner.result
step 3：
/usr/lib/python2.7/site-packages/robot/output/output.py
def __init__(self, settings):
AbstractLogger.__init__(self)
self._xmllogger = XmlLogger(settings.output, settings.log_level) ----------------------进入这一步
self.listeners = Listeners(settings.listeners, settings.log_level)
self.library_listeners = LibraryListeners(settings.log_level)
self._register_loggers(DebugFile(settings.debug_file))
self._settings = settings
step 3：
/usr/lib/python2.7/site-packages/robot/output/xmlogger.py
def __init__(self, path, log_level='TRACE', generator='Robot'):
self._log_message_is_logged = IsLogged(log_level)
self._error_message_is_logged = IsLogged('WARN')
self._writer = self._get_writer(path, generator)
self._errors = []
打log
def init(self, path, log_level='TRACE', generator='Robot'):
mylogger.info('Debug xmllogger 1')
mylogger.info(path)
mylogger.info('Debug xmllogger 2')
mylogger.info(log_level)
self._log_message_is_logged = IsLogged(log_level)
mylogger.info('Debug xmllogger 3')
self._error_message_is_logged = IsLogged('WARN')
mylogger.info('Debug xmllogger 4')
mylogger.info(generator)
self._writer = self._get_writer(path, generator)
mylogger.info('Debug xmllogger 5')
self._errors = []
呵呵哒，因为之前，在server 写了个 text 去测试runTestcaseAndInsertToMySQL（）这个方法，通过了，
所有我猜是output 或者是 report 或者是其他有个文件夹需要权限。
到这里，就在server log 中，找到output 创建在webapps下面了，加个权限，server就过了。
总结：
- 之前从来没看过 robot Framework的源码，这次对原理有了一点的认识
- output/report 的存放路径，默认是 python test.py 程序执行的地址
- 初学python， 也不知道怎么在server 上debug python site-packages，楼主是一路sudo vim 加log，才勉强debug，希望有大神可以介绍下，下次遇到问题，可以提高效率，快速定位问题。
