[Lift] Re: unit test framework
Hi Bill and ph,
Using specs matchers inside a JUnit test class is also possible using
the org.specs.SpecsMatchers trait.
However, I realize that both ScalaTest and specs suffer from the same
issue in that scenario.
When expectations are failing an exception is thrown but it is
interpreted by JUnit as an error instead of a failure.
We should instead throw an AssertionFailedError from the junit
library.
That shouldn't be a big deal to fix.

[Lift] Re: unit test framework
Hi ph,
If you end up needing to use JUnit, you can import Assertions or
ShouldMatchers or MustMatchers from ScalaTest to get a nicer
scala-like assertion syntax inside JUnit tests. JUnit won't care it
was written in Scala or used ScalaTest assertions and will run it and
generate JUnit-compatible output, since it actually is JUnit. Here's
what that might look like:
import org.junit.Test
import org.scalatest.matchers.MustMatchers._
class MyJUnitTest {
@Test
def mapKeys() {
Map("one" -> 1, "two" -> 2) must contain key ("two")
}
@Test
def stringLength() {
"hello, world" must have length (12)
}
@Test
def stringCharAtMethodRejectsBadInput() {
intercept[StringIndexOutOfBoundsException] {
"hi".charAt(-1)
}
}
}

[Lift] How to test/TDD lift apps?
Hi, Having taken the first baby steps and gotten a Lift app running, it's time to bring back some of the old engineering practices to make sure things keep running when new features are added at a rapid pace :-) I'm interested in how people are testing their Lift apps, both at the unit test level (ie. specs/scalatest with no container) and at the integration test level (running in servlet container). Also, how are you doing TDD with Lift (if at all). Specifically, I've run into the following issues: 1) Testing model classes. Many require access to S (ie to read resources) or other static Lift constructs. How can you mock these? 2) Testing snippets. Same issue with S, but more related to the actual request, eg. S.param For in-container testing it seems the practice of generating unique names for form fields, makes it difficult to use tools like Selenium to do browser based testing? How do you handle this?

[Lift] Re: Unique constraint
I actually had the same question last night. I didn't see the valUnique on mapped string. However, it seems like a better way to do this would be to change the Schemifier::ensureIndexes (line 260 in Schemifier.scala) to do "CREATE UNIQUE INDEX" on request. Is there a known reason why this is hard, or is it just that no one has taken the time to do it yet? If it's the latter (and if I can figure out what's going wrong with my attempts to build lift from source), I hope to take a stab at it in the next day or two. -Cale On Thu, Jul 2, 2009 at 7:21 AM, Joe Wass wrote: > > Yes for MappedString, valUnique . > > http://scala-tools.org/scaladocs/liftweb/1.0/net/liftweb/mapper/MappedString.html > > Joe > > > > On Jul 2, 7:55 am, Naftoli Gugenhem wrote: >> Does lift have any way to specify a unique constraint on a field, via >> schemify (or validation)? >> If not, how complex would it be to implement? > > > > --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Lift" group.

[Lift] Binding based on attributes
I'm working on an app that allows users to enter their own form templates, which are rendered to HTML forms and filled out. The results are then captured and encoded for later rendering. So the user might input something like: Name: Is this your first visit? .. Is it possible to bind the various snippets, but perform special handling on their attribute values? So, for instance, I'd bind an S.text() to all , but it'd set a variable based on its name attribute, and perform rough validations based on whether required is set to true? It isn't immediately obvious how to do this, even when digging through the Lift sources. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Lift" group.

Options and Boxes are very similar, although Boxes have "Failure" as well as
Empty (None)
Also, note that the code in the example is Scala 2.3 era code, so some
syntax has changed.

[Lift] Re: can a Snippet call a Snippet?
The open_! came right from the 'Getting Started' Todo tutorial I am
enhancing:
Listing 17: list method in TD class
def list(html: NodeSeq) = {
val id = S.attr("all_id").open_!
Nevertheless, the question remains: How can I filter the Todo items by
a Tag and render the list?
I guess I could always link to a new page and let the template drive
the snippet, but I kind of wanted to keep one page open and just do
AJAX stuff within elements.
Thanks again..

[Lift] Re: can a Snippet call a Snippet?
We really ought to get around to writing a ³guides for boxes² - its easily
one of the most confusing concepts in lift (a magnitude less confusing
than when it was called Can[T])

Don't use open_! It's dangerous.
That's why Boxes exist. They contain (or don't) something that may or may
not exist. If you use open_! in your code, it is a major mistake (a logic
error) unless the line before the open contains "if (thing.isDefined) {"

Yeah Naftoli it was m2eclipse. May have been my failure to set SCALA_HOME and the path properly. I'll review it next time I do an eclipse setup (hopefully not for a while now that netbeans is cooking with scala/lift) Seriously, thanks much for all the feedback and help gents.

[Lift] Re: Maven License Expired
Hey Jevgeni, Thats strange, I mailed you from my gmail account to your gmail, so perhaps it got spammed or something? Probably the best thing to do then would be for us to remove the current .lic from the lift installer - perhaps i'll include the latest JAR and then display a screen saying "if you want a license get in touch with XYZ" Thoughts?
