一、在robot文件中定義變量，并引用變量，變量默認(rèn)是字符串類型
*** Variable ***
${var1} tom1
${var2} 1234
***Test Cases***
case1
Log To Console Hello World!
Log To Console ${var1} ${var2}
查看運(yùn)行結(jié)果：

二、在測(cè)試?yán)齝ase1中定義局部變量，此變量只能在case1中引用，${cv1}默認(rèn)是字符串類型
*** Variable ***
${var1} tom1
${var2} 1234
***Test Cases***
case1
Log To Console Hello World!
Log To Console ${var1} ${var2}
# ${c1}是局部變量
${cv1} Set Variable 23
Log To Console ${cv1}
查看運(yùn)行結(jié)果：

三、在測(cè)試?yán)齝ase1中把局部變量${cv1}，改成全局變量，變量能在其他case中引用：
*** Variable ***
${var1} tom1
${var2} 1234
***Test Cases***
case1
Log To Console Hello World!
Log To Console ${var1} ${var2}
# ${c1}是局部變量
${cv1} Set Variable 23
Log To Console ${cv1}
# ${c1}設(shè)置為全局變量
Set Global Variable ${cv1}
case2
Log To Console ${cv1}
查看運(yùn)行結(jié)果：

四、字符串轉(zhuǎn)換為int類型方法
demo.py
def abc(v1):
return v1+5;
*** Settings ***
#引入demo.py文件
Library demo.py
*** Variable ***
${var1} tom1
${var2} 1234
***Test Cases***
case1
Log To Console Hello World!
Log To Console ${var1} ${var2}
# ${c1}是局部變量
${cv1} Set Variable 23
Log To Console ${cv1}
# ${c1}是全局變量
Set Global Variable ${cv1}
case2
Log To Console ${cv1}
case3
${res} demo.abc ${cv1}

方法一：使用Convert To Integer 命令string類型轉(zhuǎn)換為int類型
*** Settings ***
Library demo.py
*** Variable ***
${var1} tom1
${var2} 1234
***Test Cases***
case1
Log To Console Hello World!
Log To Console ${var1} ${var2}
# ${c1}是局部變量
${cv1} Set Variable 23
Log To Console ${cv1}
# ${c1}是全局變量
Set Global Variable ${cv1}
case2
Log To Console ${cv1}
case3
#${cv1}轉(zhuǎn)換為int類型，并賦值給${t}
${t} Convert To Integer ${cv1}
#${t}執(zhí)行demo.py中的abc方法
${res} demo.abc ${t}
Log To Console ${res}

方法二：使用雙層嵌套$轉(zhuǎn)換為int類型
*** Settings ***
Library demo.py
*** Variable ***
${var1} tom1
${var2} 1234
***Test Cases***
case1
Log To Console Hello World!
Log To Console ${var1} ${var2}
# ${c1}是局部變量
${cv1} Set Variable 23
Log To Console ${cv1}
# ${c1}是全局變量
Set Global Variable ${cv1}
case2
Log To Console ${cv1}
case3
${t} Convert To Integer ${cv1}
${res} demo.abc ${t}
Log To Console ${res}
case4
#雙層嵌套,${${cv1}}轉(zhuǎn)換string類型為int類型
${res} demo.abc ${${cv1}}
Log To Console ${res}
方法二測(cè)試結(jié)果
使用${${cv1}}轉(zhuǎn)換string類型為int類型.png
四、int類型轉(zhuǎn)換為字符串方法
demo.py內(nèi)容：
def abc(v1):
return v1+5;
def abcstr(v1):
return v1+'string'
直接引用int執(zhí)行string命令，提示錯(cuò)誤
*** Settings ***
Library demo.py
*** Variable ***
${var1} tom1
${var2} 1234
***Test Cases***
case1
Log To Console Hello World!
Log To Console ${var1} ${var2}
# ${c1}是局部變量
${cv1} Set Variable 23
Log To Console ${cv1}
# ${c1}是全局變量
Set Global Variable ${cv1}
case2
Log To Console ${cv1}
case3
${t} Convert To Integer ${cv1}
${res} demo.abc ${t}
Log To Console ${res}
case4
${res} demo.abc ${${cv1}}
Log To Console ${res}
case5
${str_res} demo.abcstr ${res}
Log To Console ${str_res}

解決方法：使用Convert To String命令，把int類型轉(zhuǎn)換為string類型
*** Settings ***
Library demo.py
*** Variable ***
${var1} tom1
${var2} 1234
***Test Cases***
case1
Log To Console Hello World!
Log To Console ${var1} ${var2}
# ${cv1}是局部變量
${cv1} Set Variable 23
Log To Console ${cv1}
# ${cv1}是全局變量
Set Global Variable ${cv1}
case2
Log To Console ${cv1}
case3
${t} Convert To Integer ${cv1}
${res} demo.abc ${t}
Log To Console ${res}
case4
${res} demo.abc ${${cv1}}
Log To Console ${res}
#轉(zhuǎn)換${res}為string類型
${str} Convert To String ${res}
${str_res} demo.abcstr ${str}
Log To Console ${str_res}
