Skester let you create your own unit tests using Skript. Why should you make unit tests? Simply because you can avoid bugs in your scripts. Unit tests will repeat the same tasks that you ask, so if one of them fail but worked before, it means you broke something.
Usage:
Code:
command test [<text>]:
trigger:
it "should test this command":
it "should be the console which execute this command":
assert equal sender to console with error message "Only console can execute this command!"
it "should have an argument named a":
assert not null arg-1 with error message "There are an argument"
assert equals arg-1 to "a" with error message "First argument isn't a"
