Question

我有以下文本文件。

[box_1]
show ethernet 
show adjacency
show log
[box_2]
run ethernet 
run adjacency
show log

我需要编写一个机器人文件，如果遇到[box_1]，它将运行，

run ethernet 
run adjacency
show log

如果遇到[box_2]，它将在其下运行以下命令。

这是我的机器人代码：

${File}=    Get File  Resources\\Source\\textfile.txt
@{list}=    Split to lines  ${File}    
Log    ${list}
${op}=    Get From List ${list}    0    
log    ${op}
${first_line}=    Get Slice From List   ${list}    1
:FOR    ${line}    IN    @{first_line}
\   ${result}=    Run Keyword If    '${op}'=='[${box_1}]' and     run_command    ${line}
\   ${result}=    Run Keyword If    '${op}'=='[${box_2}]' and     run_command    ${line}

但它只识别[box_1]而不是[box_2]。并且命令后面可以有多个方框。有人可以帮忙吗？

感谢。

Answer 1

您只能在

中分配${op}一次

${op}= Get From List ${list} 0

永远不会改变它。这就是为什么它总是[box_1]而永远不会成为[box_2]。您必须将赋值转换为FOR - 循环并更改其余代码，以便执行不同box - es之间的命令。

Answer 2

虽然@Psytho是对的，但解决问题还不够。

在下面的示例中，我添加了所需的库和自定义关键字来模仿运行命令Operatingsystem关键字。

在这个例子中，我跳过标题并执行命令。以类似的方式，您可以使用${match[0]}中的值来了解当前有效的标头，并在您确定要执行的操作时使用它。

*** Settings ***
Library    String    
Library    Collections
Library    OperatingSystem    

*** Test Cases ***
TC v1
    ${File}=    Get File  textfile.txt
    @{lines}=    Split to lines  ${File}    

    :FOR    ${line}    IN    @{lines}
    \    ${match}  Get Regexp Matches    ${line}    \\[(.*)\\]    1
    \    ${count}  Get Length    ${match}
    \    ${result}  Run Keyword If    ${count} == 0    run_custom_command    ${line}  
TC v2
    @{commands}    Get Commands    box_2    textfile.txt
    :FOR    ${command}    IN    @{commands}
    \    run_custom_command    ${command}    

    @{commands}    Get Commands    box_1    textfile.txt
    :FOR    ${command}    IN    @{commands}
    \    run_custom_command    ${command}       

*** Keywords ***
Run Custom Command
    [Arguments]    ${command}
    Log    Run Command: ${command}
    [return]    SUCCESS

Get Commands
    [Arguments]    ${ENV}    ${filepath}
    ${string}=    Get File            ${filepath}
    ${match}=     Get Regexp Matches  ${string}    \\[${ENV}\\]\\n((.|\\n)*?)(\\[|$)    1
    @{lines}=     Split to lines   ${match[0]}
    [Return]    ${lines}

编辑：添加了第二个仅依赖正则表达式的选项。

*** Variables ***
${A}    A
${B}    B
${C}    c
*** Keywords ***
Test
    Log To Console    ${A}
    Log To Console    ${B}
    Log To Console    ${C}
    [Return]    ${A}    ${B}    ${C}    

*** Test Cases ***
Test1
    ${A0}    ${B0}    ${C0}    Test
    Log To Console    ${A0}
    Log To Console    ${B0}
    Log To Console    ${C0}


When you are calling the keyword in the test case u can assign the return variables as above.`
