Merge: niunit: fix after/before test calls
The specification of `nitunit` states that before and after methods can be called to initialize or clean test related things:
~~~nit
module my_test_suite
class MyTestSuite
super TestSuite
redef fun before_test do
# complex things to set up the test
end
redef fun after_test do
# complex things to tear down the test
end
fun test_foo do end
fun test_bar do end
end
~~~
In the above example, `nitunit` will call the methods precisely in this order:
~~~nit
test_before
test_foo
test_after
test_before
test_bar
test_after
~~~
Before this PR, the before and after methods were only call if a redefinition of the before/after method exists locally in the test suite. Inheritance was not considered:
~~~nit
module my_test_suite
class TestBase
super TestSuite
redef fun before_test do # ...
redef fun after_test do # ...
end
class MyTestSuite
super TestBase
fun test_foo do end
fun test_bar do end
end
~~~
So the output was only:
~~~nit
test_foo
test_bar
~~~
This PR fixes that behavior.
