The fixture chaining with instances allows you to store an object instance in a Slim symbol and to use the instance as the table actor for an arbitrary Slim table.
Here createTestSlimWithString(string) is a factory method that creates a new TestSlim instance, sets the given string and returns the object.

see SlimSymbolCanHoldInstanceUsedAsParameter

script	test slim
$TEST_SLIM_INSTANCE=	create test slim with string	Uncle
start	$TEST_SLIM_INSTANCE
check	get string arg	Uncle

We can use it for a decision table.

$TEST_SLIM_INSTANCE

get string arg?

Uncle

The SlimHelperLibrary is a class that is automatically available as a library fixture. It contains methods to get and set the script table actor in the Slim StatementExecutor.

• getFixture() returns the current table actor
• pushFixture() gets the current table actor and pushes it onto a stack
• popFixture() pops the actor from the stack and sets it in the StatementExecutor

The pushFixture() and popFixture() methods can be used to have scenarios that change the current actor, but restore it at the end of the scenario.
So a scenario can behave more like a sub routine with local scope (but is not limited to it).

scenario	do something with	name	and restore old fixture
push fixture
start	test slim
set string	@name
check	get fixture	TestSlim: 0, @name
check	get string arg	@name
$@name_INSTANCE=	get fixture
pop fixture

script	test slim	2
set string	Uncle
check	get fixture	TestSlim: 2, Uncle
do something with	Bob	and restore old fixture
check	get string arg	Uncle

script	$Bob_INSTANCE
check	get string arg	Bob
