I think the problem is that the version in CoreMatchers
never got fixed
from javahamcrest.
I'm surprised this hasn't gotten more attention! This is a problem in the most obvious use case, i.e.
import static org.hamcrest.core.IsInstanceOf.*;
import static org.hamcrest.core.Is.*;
import org.junit.Test;
import static org.junit.Assert.*;
public class HamcrestTest {
interface FooInterface { }
class Foo implements FooInterface { }
class FooBar extends Foo { }
@Test
public void isTest() {
Foo someFoo = new FooBar();
FooInterface interfaceRef = someFoo;
assertThat(someFoo, isA(FooBar.class)); // Doesn't compile
assertThat(interfaceRef, isA(Foo.class)); // Doesn't compile
assertThat(someFoo, instanceOf(FooBar.class)); // Compiles correctly
assertThat(interfaceRef, instanceOf(Foo.class)); // Compiles correctly
}
}
from javahamcrest.
Any hope of this eventually being released?

junit:4.13 depend on hamcrest-core:1.3 also has this problem
feel free to raise PR with junit so v4.14 could be upgrade to the latest version, that being currently org:hamcrest:hamcrest:2.2
v1.x is dead and out of support
v2.x i'm still trying to learn the guts and help with patches... so semi in support
from javahamcrest.
"completely wrong" were Nat's exact words btw - nothing to do with me.... :-)
from javahamcrest.
This is interesting in conjunction with some of Nat's other discussions on the matter:
http://code.google.com/p/hamcrest/issues/detail?id=83#c13
from javahamcrest.
It should be <T> Matcher<Object> isA(Class<T> expectedType, Matcher<? super T> downcastMatcher)
from javahamcrest.
Which is a matcher of object not T. That would do it I think.

I'll have a go at this soon... watch this space :)
from javahamcrest.
oddly all the angle brackets in the type signature didn't appear in the email i got from github... hence my comment about Object, not T - which you can see here but not in the email...
from javahamcrest.
Has there ever been any progress on this issue? I made my own version of isA() to get around the issues discussed here.
from javahamcrest.
@EarthCitizen: would be nice to see it as a Gist.
from javahamcrest.
isA() is an alias for instanceOf() is it not? What about something like isClass() for exact Class matching?
from javahamcrest.
I've submitted an Pull Request (#127) to fix this. The behavior of isA
is documented as shortcut to instanceOf
. I've enhanced tests to check if the beavior is similar and changed the methods return a Matcher<?>
instead of Matcher<TheClass.class>
.
from javahamcrest.
Fixed
from javahamcrest.
Could you please give us an indication of which version this was/will be released for?
I'm currently using java-hamcrest:2.0.0.0
and it still has the same incorrect signature.
Thanks.
from javahamcrest.
This change hasn't been released yet. I'm not a Hamcrest member so I can't tell when they plan to release the next one, but for now it looks like you'll have to build from source.
Unfortunately master still has the version number listed as 2.0.0.0, so you'd probably have to change that in your build if you're going to add it to a local repo.
from javahamcrest.
hamcrest:2.1
has this problem...
from javahamcrest.
junit:4.13 depend on hamcrest-core:1.3 also has this problem
from javahamcrest.
hamcrest:2.1
has this problem...
does org:hamcrest:hamcrest:2.2
have the problem?
