robotframework - 将返回值附加到 Robot Framework 中的列表

Question

我的测试步骤创建了 5 个工作线程来将文件上传到服务器，并为每个线程返回服务器 HTTP 响应代码。
我想将这些附加到每个步骤的响应代码列表中。

TC001_Single_User_Upload
   [Documentation] Uploading single file by single user
   ${result}       single user test file upload    test_file.txt    test1   test
   Append To List  @{RESPONSE_LIST}    ${result}
   ${result}       single user test file upload    test_file.txt    test1   test
   Append To List  @{RESPONSE_LIST}    ${result}
   log variables
   log many     @{RESPONSE_LIST}

我当前的日志文件显示:

20171127 13:59:01.911 - INFO - @{RESPONSE_LIST} = [ ]
20171127 13:59:01.911 - INFO - @{result} = [ <Response [201]> | <Response [201]> | <Response [201]> | <Response [201]> | <Response [201]> ]

问:为什么我的@{RESPONSE_LIST} 是空的？

Answer 1

Append to list 的第一个参数需要是一个列表对象。当您使用 @ ，这就像您将列表中的每个元素都作为一个新参数一样。

解决方法是更改​​@至 $ :

Append To List  ${RESPONSE_LIST}    ${result}

来自 robot framework user guide :

When a variable is used as a scalar like ${EXAMPLE}, its value will be used as-is. If a variable value is a list or list-like, it is also possible to use as a list variable like @{EXAMPLE}. In this case individual list items are passed in as arguments separately.
