Jenkins：python-unitest选择失败的版本号进行重跑失败的用例

Posted 2020-11-16 channy14

Jenkins配置：

1.增加字符参数FAIL_VERSION，默认为no

2.buid的时候，加一个判断，当有输入版本号的时候走重跑的路

if [[ "$FAIL_VERSION" == "no" ]];then
    python $WORKSPACE/JenkinsWorker.py
else
    python /usr/local/failcaserun/start_run_failcase.py $WORKSPACE $FAIL_VERSION
fi

 

源码如下：

    error_count = test_result.error_count
    print("用例执行失败个数为%s" % failure_count)
    print("用例执行错误个数为%s" % error_count)
    if failure_count == 0 and error_count == 0:
        print "正常退出"
    else:
        print "异常退出"
        raise Exception("用例执行失败")
