roboframwork框架扩充（失败用例重新跑）

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。打个比方，用例A第一次执行失败了，立刻再重跑，再失败，立刻再重跑，成功了，那么，最后在生成的日志里面看到的就是最后那一次的运行数据，之前两次被完全过滤掉，只有在控制台中才可以看到它们的痕迹。   eg：pybot.bat --retry 3 e:\robot\test retry设置为3，用例执行失败后会再次执行，每条用例最大执行次数为3成功后不会再执行。   修改代码如下： 1、robot/run.py 修改USAGE字符串，增加 -X --retry retry         Set the retry times if test failed.这一段 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. -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（被我编辑了一下，关键字没高亮了，不过没关系）

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) 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 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字符串，增加 -X --retry retry         Set the retry times if test failed.这一段 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. -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/).

如果重跑次数达到设置上限，仍然失败，则报告显示为最后一次失败数据（结果）：
