RE: T5: testing using PageTester and EasyMock
Hi Alex,
Testing pages as POJOs is quite simple. You can roll your own very,
very, very simple service injector and inject EasyMock services into the
pojo. I have done it using reflection. So I have a class that takes the
page instance being tested in the constructor (and the test class too)
and for each field annotated with @Inject it creates a strict mock and
sets the field to that value. It also adds the mock to an internal List
if mocks. Then the class provides convenience replay, reset, verify
methods that iterate over the whole list. The test class also has fields
that use a custom annotation (@Mock) these are injected with the same
values as those added to the page under test. So you end up with a test
class with populated mocks, a page class with populated services and a
helper class with the same mocks held in an iterable fashion for
convenience.

Subject: Re: T5: testing using PageTester and EasyMock
I was grappling with this issue myself, I still don't have a good answer
to
it. Because T5 is so heavily annotation driven (with the IoC and the
framework doing a lot of the magic heavy lifting behind the scenes),
testing
the pages as POJOs (e.g. setting some properties, performing an action,
inspecting the state of the page) is not immediately obvious.
I've looked through some of the T5 unit tests (w/ EasyMock), and often
times
a page has a special (e.g. package private) method to inject services
that
otherwise the framework would inject. So, for example, if the page used
to
have an :
@Inject
FooService fooService
@Inject
BarService barService
Then, the page class would usually have a package private method like
this :
void setServices(FooService fs, BarService bs) {
this.fooService = fs;
this.barService = bs;
}
Anyway, there certainly is room for improvement, most advanced web
framework
have a way of testing pages/components as Pojos. Although the solution
above
works OK (and if you think about it, it's still pojos), it certainly
isn't
the first thing to think of once you get used to having Tapestry
injecting a
bunch of things into your pages. From a conceptual point of view, when
you're *unit *testing a page, you really DON'T want to have the real
services injected, and you'd probably just want to have
mocks/stubs/fakes in
their place that return the data needed to unit test the page. Now, if
you
were doing more of an integration type of test (e.g. where you test
how
the page works with the *real* service), then it's a different ball
game,
you do need the real services injected (for which you can still use the
above approach and not depend on the IoC to do it for you).
I guess the alternative would be to have a test context for binding
test/mock instances of the dependent services and somehow ask T5 to
inject
them into the page being tested. But then, it wouldn't really be unit
testing as the tests would depend on a whole bunch of things other than
the
unit being tested.
Let's keep this discussion rolling, we certainly need a little more info
on
testing in T5.
Cheers,
Alex Kotchnev

tell the PageTester class the name of your filter so it can load

not
the plain tapestry filter? All my services are Spring services so as
soon as I try and run a test I get a load of errors about no service

Any ideas on this one either?
I'm having quite a hard time testing anything beyond the most

Hi Russell I am not sure exactly what you mean that you couldn't build Tapestry Easymock services, but let me explain what I am doing: I am running a Maven setup, so if my tapestry services are in: scr.main.java.web.services the relevant tests are in scr.test.java.web.services.

RE: T5: testing using PageTester and EasyMock
Hi Peter,
Thanks for that. That is just normal EasyMock testing isn't it? I don't see
where tapestry comes into that at all? You are creating the instances of all
the classes and you are creating the instance of the class under test aren't
you? Where is the PageTester and Tapestry IoC and all that (or have you missed
some code, or am I missing something?)
What I meant was this:- In the src/main/java tree I have MyAppModule which has
some services like
Binder.bind(MyService.class, MyExpensiveExternalImpl.class)
But in my src/test/java tree I have
@SubModule( { MyAppModule.class })
MyAppTestModule
public static MyService buildMyService () {
return EasyMock.createMock(MyService.class);
}
(In the actual App the MyService Impl will be provided by Spring but that is by
the by)
So that when I use PageTester in my tests I can go
MyService myMockService = pageTester.getRegistry().getService(MyService.class);
EasyMock.expect(myMockService.expensiveExternalMethodCallToCreditCardGatewayIdontReallyWantToTest(myCardNumber)).andReturn(authCode);
But the problem is...the registry returns a Proxy that contains a
JustInTimeObjectCreator so EasyMock won't have no truck with my mock service.
Boo.

Re: T5: testing using PageTester and EasyMock
Russell,
this is just speculation, as I haven't tried this on my own, but it seems
to me that you'll have to do the EasyMock setup training inside your test
module, e.g. :
@SubModule( { MyAppModule.class })
MyAppTestModule
public static MyService buildMyService () {
MyService myMockService =
EasyMock.createMock(MyService.class);
EasyMock.expect(myMockService.
expensiveExternalMethodCallToCreditCardGatewayIdontReallyWantToTest(myCardNumber)).andReturn(authCode);
}
Unfortunately, with an approach like this, you'd have to have different
buildMyService method for each test case for which you need to train the
Mock... I'm not sure how that would work, maybe you can have your
MyAppTestModule use something from the test case that will train the
myMockService based on the individual testcase expectations.
Keep us posted on how this works.
Cheers,
Alex Kotchnev

RE: T5: testing using PageTester and EasyMock
Alex,
Yeah. I think that the approach you outline may well work but is
unworkable (if you know what I mean). I hold out for some way of
stripping the proxy from my mock service (using reflection to fire the
Object Creators create method and using the un proxied mock).
The problem with training the mock in the test case is that you don't
get the mock from the registry, you get a proxy wrapped mock.

Hi Peter,
How have you done this? When I try to use Tapestry to Build my
EasyMock
services the resultant proxies are rejected by EasyMock as not being
EasyMock proxies...

RE: T5: testing using PageTester and EasyMock
Right. I done it. I'll write a wiki post about it this evening.
In short, only services with an interface are wrapped in the
ObjectCreator proxy. I just use reflection to grab the ObjectCreator
field from the proxy and fire its create method and use the resultant
service.
Sweet

Alex,
Yeah. I think that the approach you outline may well work but is
unworkable (if you know what I mean). I hold out for some way of
stripping the proxy from my mock service (using reflection to fire the
Object Creators create method and using the un proxied mock).
The problem with training the mock in the test case is that you don't
get the mock from the registry, you get a proxy wrapped mock.
Cheers
Russell

Russell,
this is just speculation, as I haven't tried this on my own, but it
seems
to me that you'll have to do the EasyMock setup training inside your
test
module, e.g. :
@SubModule( { MyAppModule.class })
MyAppTestModule
public static MyService buildMyService () {
MyService myMockService =
EasyMock.createMock(MyService.class);
EasyMock.expect(myMockService.
expensiveExternalMethodCallToCreditCardGatewayIdontReallyWantToTest(myCa
rdNumber)).andReturn(authCode);
}
Unfortunately, with an approach like this, you'd have to have different
buildMyService method for each test case for which you need to train
the
Mock... I'm not sure how that would work, maybe you can have your
MyAppTestModule use something from the test case that will train the
myMockService based on the individual testcase expectations.
Keep us posted on how this works.
Cheers,
Alex Kotchnev

Hi Peter,
Thanks for that. That is just normal EasyMock testing isn't it? I
don't see
where tapestry comes into that at all? You are creating the instances
of all
the classes and you are creating the instance of the class under test
aren't
you? Where is the PageTester and Tapestry IoC and all that (or have
you
missed some code, or am I missing something?)
What I meant was this:- In the src/main/java tree I have MyAppModule
which
has some services like
Binder.bind(MyService.class, MyExpensiveExternalImpl.class)
But in my src/test/java tree I have
@SubModule( { MyAppModule.class })
MyAppTestModule
public static MyService buildMyService () {
return EasyMock.createMock(MyService.class);
}
(In the actual App the MyService Impl will be provided by Spring but
that
is by the by)
So that when I use PageTester in my tests I can go
MyService myMockService =
pageTester.getRegistry().getService(MyService.class);
EasyMock.expect(myMockService.expensiveExternalMethodCallToCreditCardGat
ewayIdontReallyWantToTest(myCardNumber)).andReturn(authCode);
But the problem is...the registry returns a Proxy that contains a

Re: T5: testing using PageTester and EasyMock
I was grappling with this issue myself, I still don't have a good answer to
it. Because T5 is so heavily annotation driven (with the IoC and the
framework doing a lot of the magic heavy lifting behind the scenes), testing
the pages as POJOs (e.g. setting some properties, performing an action,
inspecting the state of the page) is not immediately obvious.
I've looked through some of the T5 unit tests (w/ EasyMock), and often times
a page has a special (e.g. package private) method to inject services that
otherwise the framework would inject. So, for example, if the page used to
have an :
@Inject
FooService fooService
@Inject
BarService barService
Then, the page class would usually have a package private method like this :
void setServices(FooService fs, BarService bs) {
this.fooService = fs;
this.barService = bs;
}
Anyway, there certainly is room for improvement, most advanced web framework
have a way of testing pages/components as Pojos. Although the solution above
works OK (and if you think about it, it's still pojos), it certainly isn't
the first thing to think of once you get used to having Tapestry injecting a
bunch of things into your pages. From a conceptual point of view, when
you're *unit *testing a page, you really DON'T want to have the real
services injected, and you'd probably just want to have mocks/stubs/fakes in
their place that return the data needed to unit test the page. Now, if you
were doing more of an integration type of test (e.g. where you test how
the page works with the *real* service), then it's a different ball game,
you do need the real services injected (for which you can still use the
above approach and not depend on the IoC to do it for you).
I guess the alternative would be to have a test context for binding
test/mock instances of the dependent services and somehow ask T5 to inject
them into the page being tested. But then, it wouldn't really be unit
testing as the tests would depend on a whole bunch of things other than the
unit being tested.
Let's keep this discussion rolling, we certainly need a little more info on
testing in T5.
Cheers,
Alex Kotchnev
