Question

如果其中一个条件成立，我需要检查将要通过的条件。

我想使用的关键字如下：

Page Should Contains Element    //some xpath    OR 
Page Should Contains Element    //some xpath    OR 
Page Should Contains Element    //some xpath    OR 
Page Should Contains Element    //some xpath

使用运行关键字但无法使用

Answer 1

您可以使用|连接XPath结果集做一个等同于OR的东西。

${count}    Get Matching Xpath Count    //div[@prop='value'|//table[@id='bar']|//p
Run Keyword If    ${count} > 0    Some Keyword

如果您只是想要失败，如果找不到任何XPath：

Page Should Contain Element    xpath=//div[@prop='value'|//table[@id='bar']|//p

Answer 2

您可以通过${el1 present}= Run Keyword And Return Status Page Should Contains Element //some xpath1 ${el2 present}= Run Keyword And Return Status Page Should Contains Element //some xpath2 ${el3 present}= Run Keyword And Return Status Page Should Contains Element //some xpath3 ${el4 present}= Run Keyword And Return Status Page Should Contains Element //some xpath4 Run Keyword If not ${el1 present} or not ${el2 present} or not ${el3 present} or not ${el4 present} Fail None of the elements is present on the page来电的组合来完成您的要求。

${some element present}=  Run Keyword And Return Status     Page Should Contains Element    //some xpath1
${some element present}=  Run Keyword If  not ${some element present}    Run Keyword And Return Status     Page Should Contains Element    //some xpath2    ELSE    Set Variable    ${some element present}
${some element present}=  Run Keyword If  not ${some element present}    Run Keyword And Return Status     Page Should Contains Element    //some xpath3    ELSE    Set Variable    ${some element present}
${some element present}=  Run Keyword If  not ${some element present}    Run Keyword And Return Status     Page Should Contains Element    //some xpath4    ELSE    Set Variable    ${some element present}

Run Keyword If  not ${some element present}   Fail  None of the elements is present on the page

虽然这种方法很简单，但它不是最理想的 - 它会检查每个元素，即使第一个元素可能存在，也不需要检查第2个，第3个和第4个元素。这个（非常有表现力的）版本会这样做：

Run Keyword If

它使用Page Should Contain Element返回被调用关键字的值的事实。

总之，当应检查所有条件（and）时最好使用第一种方法（最后使用相应的逻辑条件 - 与or相关联，而不是{{1}}在这个例子中）第二个 - 只要一个就足够了，如果发现其中一个是真的，则不应检查其余部分。

如何在Robot Framework中使用OR条件？
