The boss asked me to write an app automation -- yaml file reading -- with the whole framework source code attached

Preface

Here is the little brother said test , I stopped for a long time , Mainly in the automation framework , These are the things described in this article . The frame is finished , The rest is to slowly decompose , In the form of an article .

readyaml

This chapter is still about what was not covered in the previous chapter . Read yaml file . We are based on yaml Files as the basis for automated use cases . So it is necessary to read it . Even if it's excel It's the same .

Look at the code

# encoding=utf-8
# ---- Qing'an —---
#  WeChat ：qing_an_an
#  official account ： Measured number der

import yaml

class YamlRead:
    def __init__(self, yamlPath):
        ''' If it's the first call , Read yaml file , Otherwise, the previously saved data will be returned directly '''
        if os.path.exists(yamlPath):
            self.yamlPath = yamlPath
        else:
            raise FileNotFoundError('yaml file does not exist ')
        self._data = None  #  preservation yaml The data of 

    @property  #  Change a method into a property to call ,
    def getData(self):
        if not self._data:
            with open(self.yamlPath, mode='rb') as f:
                self._data = yaml.load(f, Loader=yaml.FullLoader)
        return self._data

There are some notes here , A simple understanding is that a yaml File path , Made a series of judgments , Finally, get the contents , And return the result value . Other codes are used to verify such an operation , Dealing with exceptions .

Here, you don't need to call for the next call (), So here we add a decorator , take getData Call... As a property . If you don't understand or don't understand , You can look at the front python article .

How to use

In combination with what was said in the previous section configs class , stay case Write a yaml file . Code up ：

# encoding=utf-8
# ---- Qing'an —---
#  WeChat ：qing_an_an
#  official account ： Measured number der

import os

class Config:
    '''  The relative path of all files under the project '''
    Base_Path = os.path.abspath(os.path.dirname(os.path.abspath(__file__)) + '/..')
    Base_yaml = Base_Path + r'\case\login.yaml'
    
re = Config()

Then call the printer to see , Path splicing has OK 了 . So is this omnipotent ？ The answer is , No, it isn't . This is just to facilitate the management of some files , It's not a panacea .

Finish here , We then went directly to the YamlRead Call it in

from configs.readconfig import re

r = YamlRead(re.Base_YAML).getData
print(r)

I omitted the code in the above example , Duplication is too much trouble , The following results can be obtained by printing after calling ：

[{'mode': 'time', 'time': 5}, {'until': 'presence_located', 'mode': 'inputs_', 'loc': 'id', 'ele': 'com.mxchip.project352:id/etPhone', 'value': '123456', 'time': 10}, {'until': 'presence_located', 'mode': 'inputs_', 'loc': 'class name', 'ele': 'android.widget.EditText', 'value': 'jx123456', 'num': 1}, {'until': 'visibility_located', 'mode': 'clicks_', 'loc': 'id', 'ele': 'com.mxchip.project352:id/cbAgree'}, {'mode': 'time', 'time': 5}, {'until': 'text_element', 'mode': 'clicks_', 'loc': 'xpath', 'text': ' Sign in ', 'ele': '//*[@text=" deng "]'}]

Last , Post my yaml File format comes out ：
