Automation One By One - Robot Framework - 数据类型

Robot Framework中的数据类型均是通过变量（Variable）来表达的。

Robot Framework提供以下几种数据类型：

1. 字符串：${variable}, ${get value from keyword}, 80 ... 默认均是字符串类型

2. 数值型：表达数值型，必须使用${Numbers}来表示

Test Case	Action	Argument	Argument	Comment
Example 1A	Connect	example.com	80	# Connect gets two strings as arguments
Example 1B	Connect	example.com	${80}	# Connect gets a string and an integer
Example 2	Do X	${3.14}	${-1e-4}	# Do X gets floating point numbers 3.14 and -0.0001

3. 布尔值

Test Case	Action	Argument	Argument	Comment
Boolean	Set Status	${true}		# Set Status gets Boolean true as an argument
	Create Y	something	${false}	# Create Y gets a string and Boolean false

4. Null/None值

Test Case	Action	Argument	Argument	Comment
None	Do XYZ	${None}		# Do XYZ gets Python None as an argument
Null	${ret} =	Get Value	arg	# Checking that Get Value returns Java null
	Should Be Equal	${ret}	${null}

上述这些类型的变量均是大小写不敏感的,即 ${True} and${true} 是相等的. 另外,
${None} and${null} 属于属于同义词。

5. 空格、Empty

Robot Framework允许你使用${SPACE},${EMPTY}来表示空格及空

Test Case	Action	Argument	Argument
One Space	Should Be Equal	${SPACE}	\ \
Four Spaces	Should Be Equal	${SPACE * 4}	\ \ \ \ \
Ten Spaces	Should Be Equal	${SPACE * 10}	\ \ \ \ \ \ \ \ \ \ \
Quoted Space	Should Be Equal	"${SPACE}"	" "
Quoted Spaces	Should Be Equal	"${SPACE * 2}"	" \ "
Empty	Should Be Equal	${EMPTY}	\
