在robotframework中新建一个线程执行sikuli

可以使用Python的`threading`模块在Robot Framework中创建新线程，然后在该线程中执行Sikuli。

以下是一个示例代码：

*** Settings ***
Library           String
Library           Process
Library           OperatingSystem

*** Test Cases ***
Run Sikuli in a new thread
    ${thread} =    Run Keyword In Separate Thread    _run_sikuli
    Wait Until Keyword Succeeds    10s    1s    Thread Should Be Alive    ${thread}
    Log    Sikuli thread is running in the background.
    # do other stuff here
    # ...
    Run Keyword If    Thread Should Be Alive    Terminate All Processes

*** Keywords ***
_run_sikuli
    ${process} =    Start Process    /path/to/sikuli-script.py    shell=True
    ${stdout}    ${stderr}    ${rc} =    Wait For Process    ${process}
    Log    Sikuli process finished with return code ${rc}. Output: ${stdout}

在上面的例子中，我们使用`Run Keyword In Separate Thread`关键字在一个新线程中执行`_run_sikuli`关键字。然后使用`Wait Until Keyword Succeeds`关键字等待线程启动，并在日志中输出一条消息。当需要终止所有进程时，我们使用`Thread Should Be Alive`关键字检查线程是否仍在运行，并使用`Terminate All Processes`关键字终止所有进程。
