如何使用机器人框架将两个值作为字符串进行比较？

Question

当对象不相等时如何匹配值，但它们是字符串。

${tab}= 获取文本 xpath=.//[@id='projectTable_info'] ${selected text}= Fetch From Right ${tab} of ${selected text}= Fetch 从右 ${tab} of ${sele}= 从左取 ${selected text} 条目 ${empno}= 获取表格单元格
xpath=.//[@id='projectTable'] 3 6 获取价值 ${empno} ${only value}= 从右取值 ${empno} |应该是字符串 ${only value} ${sele} 转换为字符串 ${only value} 转换 字符串 ${sele} 应该等于 ${only value} ${sele}

控制台报错 如果对象在将它们转换为字符串后不相等，则失败。 INFO 参数类型有：
失败 2 ！= 2

Answer 1

您可以使用Should be equal as strings 而不是Should be equal，它会在进行比较之前将值转换为字符串。

Should be equal as strings    ${only value}    ${sele}

您的代码似乎试图手动将值转换为字符串，这也是一个合理的解决方案。不幸的是，Convert to string 的文档有点含糊，导致您使用不正确。关键字不会更改参数，它返回一个新字符串。

如果你想手动转换你的变量，你需要这样做：

${sele}=          Convert to string    ${sele}
${only value}=    Convert to string    ${only value}
Should be equal   ${only value}    ${sele}

此脚本尝试将输入转换为浮点数并比较 Python 2 中的值：

def should_be_x_than (self, number1, relation, number2):
    '''
    This keyword makes relation between 2 numbers (it converts them to number)
    Accepted relations:
    < > <= => =
    '''
    if relation =="<":
        return float(number1) < float(number2)
    if relation ==">":
        return float(number1) > float(number2)
    if relation =="=>":
        return float(number1) >= float(number2)
    if relation =="<=":
        return float(number1) <= float(number2)
    if relation =="=":
        return float(number1) == float(number2)

之后我导入了该库并将其用作关键字 (Should Be X Than)。

示例：

Should Be X Than  ${num1}  <  ${num2}

也许使用 evaluate 是最简单的，尤其是在需要 rc 时

[Documentation]    = / compare two string \ =
${rc}=    evaluate    'name'=='theon'
Log To Console   \n${rc}

Answer 4

def compare(number1, relation, number2):
    if relation == "<":
        assert float(number1) < float(number2)
    if relation == ">":
        assert float(number1) > float(number2)
    if relation == "=>":
        assert float(number1) >= float(number2)
    if relation == "<=":
        assert float(number1) <= float(number2)
    if relation == "=":
        assert float(number1) == float(number2)
