这是文件
ts.txt：
*** test cases *** mytest ${color} = set variable Red Run Keyword If '${color}' == 'Red' log to console nexecuted with single condition Run Keyword If '${color}' == 'Red' or '${color}' == 'Blue' or '${color}' == 'Pink' log to console nexecuted with multiple or ${color} = set variable Blue ${Size} = set variable Small ${Simple} = set variable Simple ${Design} = set variable Simple Run Keyword If '${color}' == 'Blue' and '${Size}' == 'Small' and '${Design}' != '${Simple}' log to console nexecuted with multiple and ${Size} = set variable XL ${Design} = set variable Complicated Run Keyword Unless '${color}' == 'Black' or '${Size}' == 'Small' or '${Design}' == 'Simple' log to console nexecuted with unless and multiple or这是我执行它时得到的：
