RF常用关键字

常用关键字：

should be true   python表达式

1 ${res}  set variable  he
2 should be true  '${res}' in 'hello'    # 不加‘’号，代表变量
3 # python表达式，空格不能多于2个，$res只能应用在表达式中
4 should be true  $res in 'hello'     # 直接引用字符串本身
5 should be equal  ${1*2} ${2} # {}内会根据python语法进行计算，这种会计算里面的值并转换为int

　　

定义变量
    ${var1}     set variable  word   #定义字面量
    ${var2}     convert to integer  2  # 定义整型
    ${var3}     convert to number  4.4  # 定义数字，可以是浮点数
    log to console  ${var1}
    log to console  ${var2}
    log to console  ${var3}
    log to console  ${4+3}  # 7  数字变量
常用关键字
# should be true  注意点：数为python表达式，布尔类型，空格不能多于2个，变量前面加一个$
# should be true 它的参数本身是python 表达式语句，RF会直接用python解释器 的eval函数，来解释这个参数表达式。
    ${var1}     set variable  word
    ${var2}     convert to integer  2  # 定义整型
    ${var3}     convert to integer  3  # 定义整型
    ${var4}     create list             #定义空列表
    should be true  3==2   # 参数为python表达式，布尔类型，空格不能多于2个，变量前面加一个$
    should be true  []    # 空列表为False
    should contain  hello     he   #第一个参数包含第二个参数
    should start with  hello    h  # 第一个参数以h开头
    should end with  hello  o   # 第一个参数以o结尾
    should be empty  ${var4}    # 判断是否为空

判断两个对象是否相等
#    should be equal  ${var2}    ${var3}
    should be equal  a  a
    should be equal as integers  10     010   #转换成数字对象比较，结果是true
    should be equal  10     010     #字符串对象比较，结果是False
    should be equal as numbers  1.2     1.2
字符串比较
# $符号加变量，直接引用变量本身
    ${var}  set variable  word
#   报错Evaluating expression 'word == 'word'' failed: NameError: name 'word' is not defined
#    should be true  ${var} == 'word'
    should be true  '${var}' == 'word'  #True
    should be true  $var == 'word'  #True
整数比较
    ${var}  convert to integer  2
    log to console  ${2}   # 2
    should be true  ${var} == ${2}
    should be true  $var == ${2}
    should be true  $var == 2
