入门Robot Framework(2)——循环控制

发表于 | 分类于

  Robot Framework提供了多种种循环方式，这里介绍三种循环方法的使用。本次演示也是在之前的例子上作的修改。

FOR IN 结构

1.直接将列表置于IN 之后

For001
    : FOR    ${n}    IN    a    b    c
    \    Log    ${n}
    \    Open Browser    https://www.baidu.com/    Chrome
    \    Sleep    2
    \    Input Text    id = kw    大火
    \    Click Button    id = su
    \    Sleep    2
    \    Close Browser
    Log    Outside Loop

2.将列表在一开始就声明，然后在IN之后调用

    @{LIST}    Set Variable    a    b    c
    : FOR    ${n}    IN    @{LIST}
    \    Log    ${LIST}
    \    Open Browser    https://www.baidu.com/    Chrome
    \    Sleep    2
    \    Input Text    id = kw    大火
    \    Click Button    id = su
    \    Sleep    2
    \    Close Browser
    Log    Outside Loop

3.多个循环变量

    \    2    2    2
    \    3    3    3
    \    Log    ${NUMBER}-${TIME}-${FREQUENCY}
    \    Open Browser    https://www.baidu.com/    Chrome
    \    Sleep    2
    \    Input Text    id = kw    大火
    \    Click Button    id = su
    \    Sleep    2
    \    Close Browser
    Log    Outside Loop

FOR IN RANGE 结构

1.IN RANGE(x, y)

For004
    : FOR    ${n}    IN RANGE    1    3
    \    Log    ${n}
    \    Open Browser    https://www.baidu.com/    Chrome
    \    Sleep    2
    \    Input Text    id = kw    大火
    \    Click Button    id = su
    \    Sleep    2
    \    Close Browser
    Log    Outside Loop

2.IN RANGE(x)

    \    Sleep    2
    \    Input Text    id = kw    大火
    \    Click Button    id = su
    \    Sleep    2
    \    Close Browser
    Log    Outside Loop

3.IN RANGE(x, y, z)

For006
    : FOR    ${n}    IN RANGE    0    30    10
    \    Log    ${n}
    \    Open Browser    https://www.baidu.com/    Chrome
    \    Sleep    2
    \    Input Text    id = kw    大火
    \    Click Button    id = su
    \    Sleep    2
    \    Close Browser
    Log    Outside Loop

不难理解，从log中可以看出RF中的range用法和python中是类似的。

EXIT LOOP 退出循环

    \    Run Keyword If    ${NUMBER}-${TIME}-${FREQUENCY} == 3-3-3    Exit For Loop
    \    Log    ${NUMBER}-${TIME}-${FREQUENCY}
    \    Open Browser    https://www.baidu.com/    Chrome
    \    Sleep    2
    \    Input Text    id = kw    大火
    \    Click Button    id = su
    \    Sleep    2
    \    Close Browser
    Log    Outside Loop

    ...    3    3    3
    \    Exit For Loop If    ${NUMBER}-${TIME}-${FREQUENCY} == 3-3-3
    \    Log    ${NUMBER}-${TIME}-${FREQUENCY}
    \    Open Browser    https://www.baidu.com/    Chrome
    \    Sleep    2
    \    Input Text    id = kw    大火
    \    Click Button    id = su
    \    Sleep    2
    \    Close Browser
    Log    Outside Loop

上面是两种退出循环的写法，可以看出效果是一样的，均在执行完2-2-2时就退出了循环。
