我正试图将json数据文件直接加载到Robot Framework中的变量中。有人能用一个例子详细说明一下如何做吗?提前感谢:(
一种方法是使用OperatingSystem库中的Get-File关键字,然后使用内置的Evaluate关键字将其转换为python对象。
例如,考虑一个名为example.json的文件,其中包含以下内容:
{
"firstname": "Inigo",
"lastname": "Montoya"
}
你可以用这样的东西来记录这个名字:
*** Settings ***
| Library | OperatingSystem
*** Test Cases ***
| Example of how to load JSON
| | # read the raw data
| | ${json}= | Get file | example.json
| |
| | # convert the data to a python object
| | ${object}= | Evaluate | json.loads('''${json}''') | json
| |
| | # log the data
| | log | Hello, my name is ${object["firstname"]} ${object["lastname"]} | WARN
当然,您也可以用python编写自己的库来创建一个做同样事情的关键字。
有一个库可用于此:HttpLibrary.HTTP
${json}= | Get file | example.json
${port} | HttpLibrary.HTTP.Get Json Value | ${json} | /port
log | ${port}
API文件可在此处获取:http://peritus.github.io/robotframework-httplibrary/HttpLibrary.html
一个常见的用法是将json数据传递到另一个库,如Http库请求。你可以做:
*** Settings ***
Library OperatingSystem
Library RequestsLibrary
*** Test Cases ****
Create User
#...
${file_data}=
... Get Binary File ${RESOURCES}${/}normal_user.json
Post Request example_session /user data=${file_data}
#...
没有直接涉及python,也没有中间json对象。
Thanks Vinay .. that helped now we can retrieve data from json file in robot framework as well
*** Settings ***
Library HttpLibrary.HTTP
Library OperatingSystem
*** Test Cases ***
Login_to_SalesForce_Json
${jsonfile} Get File c:/pathtojason/Data/testsuite.json
${username} Get Json Value ${jsonfile} /test_case1/username
log ${username}
Below is the json file structure
{
"test_case1":
{
"username":"User1",
"password":"Pass1"
}
,
"test_case2":
{
"username1":"User2",
"password1":"Pass2"
}
}
前提条件是:pip-install-可信主机pypi.python.org robotframework httplibrary
我遇到了类似的问题,这对我来说很好:
${json}获取二进制文件${json_path}nameOfJsonFile.json
它适用于我的API测试,读取.json和POST,如这里的
*** Settings ***
Library Collections
Library ExtendedRequestsLibrary
Library OperatingSystem
*** Variables ***
${uri} https://blabla.com/service/
${json_path} C:/home/user/project/src/json/
*** Test Cases ***
Name of Robot Test Case
Create Session alias ${uri}
&{headers} Create Dictionary Content-Type=application/json; charset=utf-8
${json} Get Binary File ${json_path}nameOfJsonFile.json
${resp} Post Request alias data=${shiftB} headers=${headers}
Should Be Equal As Strings ${resp.status_code} 200
也有一些情况下,您需要将读取的二进制文件(在我的例子中是${json}(转换为字典,但首先尝试这个简单的解决方案。
