StringFixture is a fixture with helper methods to allow more (String) manipulation to be done in the Wiki.
It is intended to be used is as a library[?] to add its methods to the methods available via another fixture in s script table.

This page demonstrates the features of the class (nl.hsac.fitnesse.fixture.slim.StringFixture) and therefore uses it on its own in a script table (instead of inside a script using a different fixture).

script	string fixture
check	value of	Hello	Hello
check	length of	Hello	5
ensure	text	Hello world!	contains	world
reject	text	Hello world!	contains	moon
ensure	value	Hello	differs from	Hell
ensure	value	Hello	equals	Hello
check	convert to upper case	Bye	BYE
check	convert to lower case	Bye	bye
check	remove whitespace	Hello World	HelloWorld
check	normalize whitespace	Hello World	Hello World
check	replace all	Hello ([A-Za-z]+)	in	Hello World	with	$1	World
check	replace all	(\d{4})-(\d{1,2})-(\d{1,2})	in	1975-12-3	with	$3-$2-$1	3-12-1975



Conversions to numbers (so that relative checks[?] can be done).

script	string fixture
check	convert to int	100	100
check	convert to int	100	100< 101
check	convert to double	01.5020	1.502~=1.5
check	convert to double	1.52	1.52< 2
check	extract int from	(42)	using	\((\d+)\)	group	1	42
check	extract int from	A200BC001	using	A(\d+)BC(\d+)	group	2	1

And this can be combined with usage of variables/symbols[?] and scenarios[?] to define more complex checks:

scenario	compare yyyy-M-d date _ to dd-MM-yyyy _	input, output
$date=	replace all	^(\d{4})-(\d)-(\d)$	in	@{input}	with	$1-0$2-0$3
$date=	replace all	^(\d{4})-(\d\d)-(\d)$	in	$date	with	$1-$2-0$3
$date=	replace all	^(\d{4})-(\d)-(\d\d)$	in	$date	with	$1-0$2-$3
check	replace all	^(\d{4})-(\d\d)-(\d\d)$	in	$date	with	$3-$2-$1	@{output}
