本文通过修改RF源代码，增加命令pybot参数–retry N,以实现执行过程中，test级别的用例失败后自动再执行N次，或直到成功为止，生成的日志和报告文件中只记录最后一次执行结果。
修改代码如下：
1. robot/run.py
修改USAGE文档，增加 -Z –retry retry Set the retry times if test failed.
Options
-Z –retry retry Set the retry times if test failed.
-N –name name Set the name of the top level test suite. Underscores
in the name are converted to spaces. Default name is
created from the name of the executed data source.
-D –doc documentation Set the documentation of the top level test suite.
Underscores in the documentation are converted to
spaces and it may also contain simple HTML formatting
(e.g. bold and http://url/).
增加导入模块
reload(sys)
sys.setdefaultencoding('UTF-8')
from xml.dom import minidom
RobotFramework类增加make方法
def make(self,outxml):
xmldoc = minidom.parse(outxml)
suiteElementList = xmldoc.getElementsByTagName('suite')
mySuite = []
for suiteElement in suiteElementList:
if suiteElement.childNodes is not None:
for element in suiteElement.childNodes:
if element.nodeName == 'test':
mySuite.append(suiteElement)
break
for suite in mySuite:
testElements = {}
for element in suite.childNodes:
if element.nodeName == 'test':
name = element.getAttribute('name')
if testElements.get(name) == None:
testElements.update({name:[element]})
else:
testElements.get(name).append(element)
for n,el in testElements.iteritems():
for i in el[0:-1]:
textElement = i.nextSibling
suite.removeChild(i)
suite.removeChild(textElement)
savefile = open(outxml,'w')
root = xmldoc.documentElement
root.writexml(savefile)
savefile.close()
修改RobotFramework类的main方法，插入self.make(settings.output)这段
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']).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)
LOGGER.info("Tests execution ended. Statistics:\n%s"
% result.suite.stat_message)
self.make(settings.output) #增加这一行,去掉此注释
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
2. robot/conf/settings.py
修改_cli_opts字典，增加 ‘Retry’:(‘retry’,1)
'MonitorColors' : ('monitorcolors', 'AUTO'),
'StdOut' : ('stdout', None),
'StdErr' : ('stderr', None),
'XUnitSkipNonCritical' : ('xunitskipnoncritical', False),
'Retry' : ('retry',1)} #增加这一行,去掉此注释
3. robot/model/itemlist.py
修改visit方法如下:
def visit(self, visitor):
for item in self:
if self.__module__ == 'robot.model.testcase' and hasattr(visitor,"_context"):
testStatus = ''
for i in range(0,int(visitor._settings._opts['Retry'])):
if testStatus != 'PASS':
if item.name in visitor._executed_tests:
visitor._executed_tests.pop(item.name)
item.visit(visitor)
testStatus = visitor._context.variables['${PREV_TEST_STATUS}']
else:
break
else:
item.visit(visitor)
4. robotide\contrib\testrunner\usages.py
修改USAGE文档，增加 -Z –retry retry Set the retry times if test failed.这一段
Options
-Z –retry retry Set the retry times if test failed.
-N –name name Set the name of the top level test suite. Underscores
in the name are converted to spaces. Default name is
created from the name of the executed data source.
-D –doc documentation Set the documentation of the top level test suite.
Underscores in the documentation are converted to
spaces and it may also contain simple HTML formatting
(e.g. bold and http://url/).
最后使用 pybot -Z 3 -t E:\autotest\test 即可实现失败重跑功能。
