Robotframework 如何使用robot框架检查unix进程是否正在运行

我正在尝试检查进程是否正在unix系统中运行。它可以是一个进程，也可以是多个进程。下面是我正在尝试的示例。有人能指导我如何做到这一点吗

*** Settings ***
Library    Process
Library           OperatingSystem

*** Test cases ***
Example
     ${output} =     Run process   /etc/init.d/bluetooth
     ${op}=     Is Process Running   ${output} 
     Should be equal     ${op}     True

[root@test ssh-scripts]# pybot test-process.robot 
==============================================================================
Test-Process                                                                  
==============================================================================
Example                                                               | FAIL |
Non-existing index or alias '<result object with rc 3>'.
------------------------------------------------------------------------------
Test-Process                                                          | FAIL |
1 critical test, 0 passed, 1 failed
1 test total, 0 passed, 1 failed
==============================================================================

***设置***

***测试用例***
例子
${output}=运行进程/etc/init.d/bluetooth
${op}=进程正在运行${output}
应等于${op}True
[root@testssh脚本]#pybot test-process.robot
==============================================================================
测试过程
==============================================================================
例子|失败|
不存在索引或别名“”。

/etc/init.d/bluetooth

是启动脚本，您不需要检查启动脚本，而是检查它启动的进程

关键字

运行进程

等待进程终止。您可能不会等待终止，而是希望在后台运行该进程

这对我来说就像预期的那样：

Test Processes
    ${handle}    Start Process    echo    foo    stdout=/tmp/bar
    ${output}    Is Process Running    handle=${handle}
    Should Not Be True    ${output}
    ${handle}    Start Process    yes    stdout=/dev/null
    ${output}    Is Process Running    handle=${handle}
    Should Be True    ${output}
    [Teardown]    Terminate All Processes

即，

echo

在第一个

进程运行之前终止

执行检查。但是

yes

在进程运行的第二瞬间启动并保持运行

/etc/init.d/bluetooth

启动并在第二秒保持运行

进程正在运行

以下脚本对我有效。在执行命令后，我放置了一个正则表达式模式来匹配字符串。这可以通过另一种方式实现，但这符合我的目的

感谢您的评论，我将尝试回答，我的目的是检查如下

[root@hyinit.d]#MDB_平台_PostgreSQL状态pg_ctl:服务器正在运行（PID:9997）

。我想验证这个进程是否正在运行，就像这样，我有一组进程要验证。感谢您的评论，我将尝试回答，我的目的是检查如下所示的进程
