assert_raise fails on native exceptions
---------------------------------------
Key: JRUBY-5279
URL: http://jira.codehaus.org/browse/JRUBY-5279
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.5.6
Reporter: Jeff Hodges
Assignee: Thomas E Enebo
assert_raise in test/unit does not properly handle NativeExceptions. When given
one to test against, the code in _check_exception_class checks if the class
inherits from the ruby Exception class (with `assert(Exception >= klass,...`).
This fails when a NativeException is passed into it. A similar bug was made
earlier as JTESTR-45, but the reporter focused on rspec (which was found to be
invalid) and did not follow through with test/unit and the bug was not elevated
to JRUBY. Also, this seems to have been known on the web at
[http://stackoverflow.com/questions/2187166/jruby-and-testunits-assert-raise]
with no resolution.
This code reproduces the problem:
{code}
require 'test/unit'
require 'java'
class TestAssertRaiseWithNativeException < Test::Unit::TestCase
java_import('java.util.NoSuchElementException') { 'FooError' }
java_import 'java.util.MissingResourceException'
def test_native_exception_with_renaming
assert_raise(FooError) {
raise FooError
}
end
def test_native_exception
assert_raise(Java::JavaUtil::MissingResourceException) {
raise Java::JavaUtil::MissingResourceException
}
end
end
{code}
The above tests will fail with these results:
{code}
1) Failure:
test_native_exception(TestAssertRaiseAliasedNativeException)
[assert_raise_problem.rb:15]:
Should expect a class of exception, Java::JavaUtil::MissingResourceException.
<nil> is not true.
2) Failure:
test_native_exception_with_renaming(TestAssertRaiseAliasedNativeException)
[assert_raise_problem.rb:8]:
Should expect a class of exception, Java::JavaUtil::NoSuchElementException.
<nil> is not true.
