解决RobotFramework用例执行失败自动重跑问题

使用自动化脚本进行测试，经常受环境影响等各方面导致本能成功的脚本失败，下面介绍了RFS框架下，失败重跑的方法：通过改写RobotFramework源代码增加--retry选项，实现test级别的失败用例自动再执行：失败用例会重跑N次，直至成功or 耗尽重试次数，生成的日志和报告文件中只会体现最后一次执行的结果。 修改代码如下：一、修改文件 C:\Python27\Lib\site-packages\robot\run.py　　 1）在USAGE变量里添加下面红色内容。

　Options
　　=======
　　 -X --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.

 

2）增加导入模块

reload(sys)sys.setdefaultencoding('UTF-8')from xml.dom import minidom

 3）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)breakfor 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.nextSiblingsuite.removeChild(i)suite.removeChild(textElement)savefile = open(outxml,'w')root = xmldoc.documentElementroot.writexml(savefile)savefile.close()

4）RobotFramework类的main方法，加入红色内容 self._make(settings.output)二、robot/conf/settings.py修改_cli_opts字典，增加 'Retry':('retry',3)

三、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)bd44item.visit(visitor)testStatus = visitor._context.variables['${PREV_TEST_STATUS}']else:breakelse:item.visit(visitor)

四、robotide\contrib\testrunner\usages.py  修改USAGE字符串，增加 -X --retry retry         Set the retry times if test failed.现在完成了所有配置，可以运行一下试试了。次数的配置在settings.py下retry后修改即可。
