Robot Framework - 访问者界面 - 如何获取关键字的关键字子项?

问题描述

在实现 Robot 的 之后SuiteVisitor 接口 函数def start_suite(self,suite), def start_test(self, test) 和def start_keyword(self, keyword)code> 正在按预期调用.但是当我尝试列出关键字的关键字子项时，我得到了空列表:

After implementing Robot's SuiteVisitor Interface the functions def start_suite(self, suite), def start_test(self, test) and def start_keyword(self, keyword) are being called as expected. But when I try to list the keyword children of keywords, I get empty lists:

def start_suite(self, suite):
    logger.console("Event Start Suite: {}".format(suite.name))
    for x in suite.tests:
        logger.console("-> Test Name: {}".format(x))
        for y in x.keywords:
            logger.console("---> Keyword: {}".format(y))
            for z in y.keywords:
                logger.console("-----> Child Keyword: {}".format(z))

def start_test(self, test):
    logger.console("Event Start Test {}".format(test.name))
    for x in test.keywords:
        logger.console("---> Keyword: {}".format(x))
        for z in x.keywords:
            logger.console("-----> Child Keyword: {}".format(z))

def start_keyword(self, keyword):
    logger.console("Event Start Keyword {}".format(keyword.name))
    for x in keyword.keywords:
        logger.console("-----> Child Keyword: {}".format(x))

有人能解释一下原因吗?

Can someone explain why?

我通过监听器注册访问者:

I register the visitor via the listener:

def start_suite(self, data, result):
    logger.console("Listener Start Suite")
    visitor = Visitor()
    data.visit(visitor)

是否需要我提供更多信息才能回答这个问题?

Is there more information needed from my side to be able to answer this question?

推荐答案

当我运行以下设置时，自定义套件访问者会记录测试用例中定义的关键字.主要区别在于以下示例将类添加为 prerunmodifier:--prerunmodifier SoVisitor.SoVisitor.

When I run the following setup the custom Suite Visitor logs the keywords defined in the test case. The main difference is that the below example adds the class as a prerunmodifier: --prerunmodifier SoVisitor.SoVisitor.

SoVisitor.robot

*** Test Cases ***
TC 1
    Custom Keyword
    Another Keyword

TC 2
    Custom Keyword
    Another Keyword


*** Keywords ***
Custom Keyword
    Sub Keyword
    No Operation

Another Keyword
    No Operation

Sub Keyword
    No Operation
    enter code here

SoVisitor.py

from robot.model.visitor import SuiteVisitor
from robot.api import logger

class SoVisitor(SuiteVisitor):
    def start_suite(self, suite):
        logger.console("Event Start Suite: {}".format(suite.name))
        for x in suite.tests:
            logger.console("-> Test Name: {}".format(x))
            for y in x.keywords:
                logger.console("---> Keyword: {}".format(y))
                for z in y.keywords:
                    logger.console("-----> Child Keyword: {}".format(z))

    def start_test(self, test):
        logger.console("Event Start Test {}".format(test.name))
        for x in test.keywords:
            logger.console("---> Keyword: {}".format(x))
            for z in x.keywords:
                logger.console("-----> Child Keyword: {}".format(z))

    def start_keyword(self, keyword):
        logger.console("Event Start Keyword {}".format(keyword.name))
        for x in keyword.keywords:
            logger.console("-----> Child Keyword: {}".format(x))

RED 编辑器然后生成以下命令和控制台输出:

The RED editor then generates the following command and console output:
