How to check if a string contains an other string in robot framework?

如何检查一个字符串是否包含机器人框架中的另一个字符串？

Something like

就像是

${bool} | String Contains | Hello World | World

Get Substringdoesn't help, because it needs a start index.

Get Substring没有帮助，因为它需要一个起始索引。

i have found an another solution

我找到了另一个解决方案

${match} | ${value} | Run Keyword And Ignore Error | Should Contain | full string    | substring
${RETURNVALUE} | Set Variable If | '${match}' == 'PASS' | ${True} | ${False}

${source}=    Set Variable    this is a string

# ${contains} will be True if "is a" is a part of the ${source} value
${contains}=  Evaluate   "is a" in """${source}"""

# will fail if "is a" is not a part of the ${source} value
Should Be True      "is a" in """${source}"""

# using a robotframework keyword from the String library
# it is actually a wrapper of python's "var_a in var_b" - the previous approaches
Should Contain    ${source}    is a

# as last alternative - an approach that will store 
# the result in a boolean, with RF standard keywords
# ${contains} will be True if "is a" is a part of the ${source} value
${contains}=    Run Keyword And Return Status    Should Contain    ${source}    is a

Hope the example is self-explanatory

希望这个例子是不言自明的

From the String library use, Get Lines Containing String, doc here. Then check the result.

从 String 库使用，Get Lines Containing String, doc here。然后检查结果。
