Robot Framework从测试套件元数据访问关键字

Question

I want to set for each test inside the test suite a simple report of the computer name, So I've created the following simple robot __init__.robot file:

*** Settings ***
Metadata        Executed At    Get Environment Variable   COMPUTERNAME
Library         OperatingSystem

The problem is that the Get Environment Variable is translated as a string instead of calling the keyword Get Environment Variable with the argument COMPUTERNAME

The log put is: Executed At: Get Environment Variable COMPUTERNAME

Question: How can i call some keyword from the settings Metadata ?

Answer 1

If you are asking about how to call a keyword in the Metadata setting, the answer is that you can't. What you can do, however, is call a keyword that sets the metadata. Within the Metadata setting, however, you can only define strings.

To set the metadata via a keyword is a two step process: first, call a keyword and save the return value, and then call the Set Suite Metadata keyword. You can do this in a Suite Setup by creating a custom keyword:

*** Settings ***
Suite setup    Initialize Metadata

*** Keywords ***
Initialize Metadata
    ${data}=  Get environment variable   COMPUTERNAME
    Set suite metadata    Executed At    ${data} 

If your real problem is simply that you want to set metadata based on an environment variable, use the environment variable syntax :

*** Settings ***
Metadata    %{COMPUTERNAME}
