Re: Re: Grails Testing Fixtures

I edited the Fixtures plugin:

class FixtureLoader implements ApplicationContextAware {
    
    def classLoader
    ApplicationContext applicationContext
    
    def createBuilder() {
        new FixtureBuilder(applicationContext, classLoader)
    }
    
    void load(String[] fixtures) {
        def bb = createBuilder()
        fixtures.each {
            bb.loadBeans("/fixtures/${it}.groovy")
        }
        applicationContext = bb.createApplicationContext()
    }
    
    void load(Closure beans) {
        def bb = createBuilder()
        bb.beans(beans)
        applicationContext = bb.createApplicationContext()
    }
    
    Object getProperty(String name) {
    	if (applicationContext.getProperty(name)) {
    		return applicationContext.getProperty(name)
    	}
    	return super.getProperty(name)
    }
}

This doesn't completely fix my complaints, but now I've direct access to the object created in the fixture:

   fixtureLoader.load("testing")
   def fooInstance = fixtureLoader.foo1
   def barInstance = fixtureLoader.bar1

I still have the instantiation/relationship issues, but that's due to Spring's BeanBuilder, not the Fixture plugin itself. Perhaps I'll look into what it would take to fix that as well.

Re: Grails Test Fixtures

I'm less happy with Grails Test Fixtures plugin today, as I discovered that it won't do both sides of a relationship properly. If I've got class Foo which hasMany Bar's, and Bar belongsTo Foo:

testing.groovy
beans {
   foo1(Foo) {
      name = "foobar"
      bars = [/* FAILS -> ref(bar1) */]
   }

   bar1(Bar) {
      name = "barbaz"
      foo = foo1
   }
}

I can't say bars = [bar1] because bar1 won't have been instantiated yet. Even trying to use the "deferred" object references fails. And I cannot declare bar1 first, because it won't be able to set it's foo property and will fail to save. So

   fixtureLoader.load("testing")
   def foo1 = Foo.findByName("foobar")
   // foo1.bars will be empty
   def bar1 = Bar.findByName("barbaz")
   foo1.bars = [bar1]

   // now I can start testing

Which brings me to another point: Ruby fixtures would expose foo1 and bar1 as instances for me to use, no lookup necessary (as I understand it). Maybe I'm not doing it right? Will they be there in Grails Fixtures if I use the Spring Application Context?

Re: What GOP Leaders deem wasteful in Senate stimulus bill

From CNN: "On Monday, House Republican leaders put out a list of what they call wasteful provisions in the Senate version of the nearly $900 billion stimulus bill that is being debated". I have to agree that several of these are questionable, others are defensible with "economic stimulation" in mind.

$2 billion earmark to re-start FutureGen, a near-zero emissions coal power plant in Illinois that the Department of Energy defunded last year because it said the project was inefficient. Sounds like a good idea to me, but also reeks of favoritism since it is in Obama's home state.
A $246 million tax break for Hollywood movie producers to buy motion picture film. WHAT?!
$650 million for the digital television converter box coupon program. From what I hear, the FCC underfunded this program. By $650 million though?
$88 million for the Coast Guard to design a new polar icebreaker (arctic ship). Do we really need a new polar icebreaker? Even though the polar ice is melting faster every year?
$448 million for constructing the Department of Homeland Security headquarters. I'm guessing this has gone way over budget?
$600 million to buy hybrid vehicles for federal employees. Are these fleet or personal? Upgrading the fleet to hybrid's makes sense to me, gifting personal cars doesn't.
$6 billion to turn federal buildings into "green" buildings. This one only makes sense in the scope of economic stimulus, plus it should help get solar into that 'economy of scale' that's needed to tip the pricing into accessible to the populace
$850 million for Amtrak. Again, what?!
$200 million in funding for the lease of alternative energy vehicles for use on military installations. Let the military agencies pay for this out of their normal funding.

It's really tempting to comment on every line item, but I've tried to restrain myself.

Grails Test Fixtures

Yep, more Grails. Here's the background: in December I did some skunkworks on a Grails app, which has been thrown on the trash-heap. My next project is supposed to be in Rails, which I have not used yet. I started reading a co-workers book (the book is 3 years old), and it just wasn't feeling right - though I could definitely see where Grails was inspired by Rails. My coworker/team-lead took off for a week of vacation without checking in his work. I had already begun a project, but felt it wasn't going well. I didn't want to go too far off the rails (pardon the pun), so I restarted the project in Grails.

But Grails doesn't have test fixtures (yaml), not in the core, at least. So I started searching and found a plugin that does something similar. Now I'm converting my first couple test cases, and really liking it. And I'm wondering why Test Fixtures aren't a part of the new Testing plugin that is integrated into Grails 1.1....

Groovy/Grails GPath Goodness

I couldn't find any GPath references that really discussed using it on object-graphs other than those built from XML. In my case, I needed to use GPath to get a reference to an object so I could complete a Unit Test.

The controller I'm testing persisted new objects build from a JSON string passed in, but when accessed didn't have the child objects in the same order. Even if the child objects were in the correct sequence, the Hibernate PersistentSet won't allow you to access objects by index number (job.actions[0].subject will error):

    // this is after the controller call has been made and returned
    records = service.jobsByActionSubject(testSubject)
    def job = records[0]

    // this actually results in the second/wrong action (of type "status") 
    // of the submitted json being accessed
    assertEquals testSubject, job.actions.subject[0]

So I made use of

    records = service.jobsByActionSubject(testSubject)        
    def job = records[0]
    
    // an action has an actionType, which is named
    def testAction = job.actions.find{ it.actionType.name == "pop" }
    assertEquals testSubject, testAction.subject

Sweet Sixteen

Today my first child turned 16. I haven't signed her up for driver's ed, so no worries there. But my little girl is growing up. Always independent, the last several months have been all about which colleges she is going to apply. I just realized today that I'm not ready for her to leave me yet, though I've got a couple more years to get used to the idea.

My mom reads this blog (or used to when I published frequently), I wonder what she will have to say.

Grails: Testing JSON Output

I couldn't find any resources that provided examples on how to test a Controller closure that "render[s] as JSON". Turns out it isn't terribly complicated, but I did have to root around a bit to find the right way to get ahold of the text that the controller generated.

def expectedObject = new ExpectedObject(foo: "bar")
expectedObject.save()
		    	
// Create expected JSON result
def expectedResult = expectedObject as JSON
    	
// okay, now we call the method we're testing
controller.params.foo = "bar"
controller.getObject()
def jsonResult = controller.response.contentAsString
    	
// did we get the job back as JSON?
assertEquals expectedResult.toString(), jsonResult

The key was discovering that Spring injected a MockHttpServletResponse, and that it has a contentAsString() method.

Thanks to the following resources:

Bad Behaviour

I'm watching the inauguration live, and current-President Bush just entered: has any other President even been boo'ed while leaving office?

Some people are even chanting "No More Bush". Didn't their mothers teach them to behave better than that? I'm no fan of the man (far from it), but even I consider it bad form to boo the man, especially while he still holds office. ( Jan 20 2009, 11:49:23 AM ) Politics Permalink
