Fitnesse中的symbols和variables

1.symbols 主要在表间传递信息，作用于一个page中，类似于局部变量

SaveRecordInDatabase
name	date	=key?
Bob	today	bobKey
Bill	later	billKey

 在方法名前加=表示要把结果存储在symbol中，而不是跟方法的返回结果作比较

FetchRecordsFromDatabase
key=	fetch()	name	date
billKey	true	Bill	later
bobKey	true	Bob	today

 在入参的列中加入=表示使用单元格中的symbol值

symbol是在测试执行中赋值

2.variables 类似全局变量，只要在父级页面定义了，就可以在子级页面使用

定义的方法主要有三种

• !define var {text} - as a delimited block of text
• !define var othervar - by copying the value of another variable
• !define var {${= 10 / 2 =}} - as an expression

例子：

!define myVariable {
This is the
text of
my
variable
}
variable defined: myVariable= this is the text of my variable

!define n 10
variable defined:
n=10
!define q 2
variable defined: q=2
!define d {${= ${n}
/ ${q} =}}
variable defined: d=${= ${n} / ${q} =}
${d} is : 5
IMPORTANT: If the variables
used in the expression change than also the result changes!
!define q 5
variable defined: q=5
${d} is : 2

variables在测试执行前定义好，在测试过程中不会改变
