AttributeError: startswith

Question

我要用机器人框架运行一些测试，在某些元素可见之后，我想做一些事情：

这就是我试过的：

 Page Should Contain Element  ${TRAIN_LABEL}

 element should be visible  ${TRAIN_LABEL} 

 Wait Until Keyword Succeeds  ${RETRY_TIMEOUT}  ${RETRY_INTERVAL}  Wait Until Element is Visible  ${TRAIN_LABEL}

我的TRAIN_LABEL变量：

${TRAIN_LABEL} =xpath=//*@id=‘trainHeader’，并包含(@data-TRAIN_LABEL-id，'548')

但是当我运行测试时，它给了我：

AttributeError: startswith

错误。

我怎么才能解决这个问题？

测试存在/停止于：

Page Should Contain Element  ${TRAIN_LABEL}

或

Element Should Be Visible  ${TRAIN_LABEL}

或

Wait Until Keyword Succeeds  ${RETRY_TIMEOUT}  ${RETRY_INTERVAL}  Wait Until Element is Visible  ${TRAIN_LABEL}

这三个关键词都不起作用

Answer 1

信息有限，但我会尝试：

您定义了${TRAIN_LABEL} = xpath=//*[@id='trainHeader'and contains(@data-train-id,'548')]

如果以上是变量部分，则在=后面的可选${TRAIN_LABEL}符号之后至少应该有2个空格。如果它不在变量部分中，则不能这样赋值。您需要使用Set Variable关键字：

${TRAIN_LABEL}    Set Variable    xpath=//*[@id='trainHeader'and contains(@data-train-id,'548')]
