You can Define aliases via tables in the wiki. It's also possible to add aliases via plugins. This has the advantage that the wiki is not cluttered with techical concerns.

To demonstrate this a class fitnesse.testsystems.slim.CustomTableAliasPlugin has been loaded in SetUp.

This plugin makes an alias from aliased echo fixture to the good old echo fixture.

So the following test table works:

script
given page	AliasTest	with content	!define TEST_SYSTEM {slim} | import | | fitnesse.slim.test | | script : my requirement | | check | do business logic | 42 |
check	request page	AliasTest?test	200
ensure	content contains	class="pass"
show	content
