ScalaTest for Scala IDE Plugin 0.9.1 Released!

[Bill Venners]

Hello All,

After much hard work spanning an entire year, we are proud to announce
the first official release of the ScalaTest for Scala IDE Plugin! Not
only does this plugin give Scala programmers the level of
test-framework/IDE integration that Java programmers have enjoyed with
JUnit, it goes quite a bit farther:

1. You can pretty much right click on anything that looks runnable and
run it as a test.
2. You can run just the tests you select in code, run tests you select
in reported results, rerun all tests or just previously failed tests,
or run tests in a selected class, file, or package.
3. The results pane mirrors the structure or the specification (i.e.,
if your BDD-style specification text is nested in the source, it will
appear nested in the results pane).
4. You can hop from results to test, scope, class, or line of failed code.
5. You can unfold the top of that stack that is automatically folded
so only the offending line of code is shown.
6. And, because ScalaTest is a platform that can support different
styles of testing, the plugin can be extended to grant full IDE
support for non-ScalaTest-native styles, such as a ScalaCheck
Properties classes, Specs2 Specifications, or custom styles.

You can use the plugin with any release of ScalaTest, but you'll enjoy
the most seamless IDE integration if you use ScalaTest 2.0.M2 (a very
carefully tested milestone release). You can plug it into either the
latest stable release of the Scala IDE for Eclipse (version 2.0.2), or
a nightly build of Eclipse 2.1.0.

So, how do you get the plugin? Select Help -> Install New Software in
Eclipse, and enter as your update site one of the "Scala IDE Ecosystem
update site" URLs on this page:

http://scala-ide.org/download/ecosystem.html

Select ScalaTest for Scala IDE (and the others if you don't have them
already), and click Next then Finish.

Information on the features of the integration (and some screenshots
(and the source code)) is here:

https://github.com/scalatest/scalatest-eclipse-plugin

A video demo of the plugin that I gave back at ScalaDays is here:

Info on ScalaTest 2.0.M2 is here:

Many thanks to Chua Chee Seng, George Berger, Luc Bourlier, Mirco
Dotta, Iulian Dragoș and everyone else who helped with this effort.

Enjoy!

Hi,

I believe this is a question for the Scala IDE folks. As far as I
know, the Juno limitation is that Scala IDE for Eclipse does not yet
run on Juno.

Hi Kevin, 

Just curious about the error message "Unrecognized arguments: -k, localhost, 62574.", are you using ScalaTest 2.0.M2?  The -k argument is only recognized by ScalaTest 2.0, when it detects that you have ScalaTest 1.8.x it should just use the default Runner UI in ScalaTest, do you have both ScalaTest 1.x and ScalaTest 2.0 in the classpath?

Thanks.

Best Regards, 

Chee Seng

Any chance it will work in Eclipse Juno soon? I know the release notes indicate Indigo is required.  

(BTW It seemed to install okay into Juno. But when I tried to run a test, the progress display appears but this error message was in the console for the test run:

"Unrecognized arguments: -k, localhost, 62574.")

You're right. I had Scalatest 1.8 in the classpath. I guess it came in as a transitive dependency when SBT built the .classpath file.

Anyway I removed it.  Now when I launch Scalatest at a package I see this:

WARNING: -p has been deprecated and will be reused for a different (but still very cool) purpose in ScalaTest 2.0. Please change all uses of -p to -R.

DEBUG: Discovery Starting

Exception in thread "main" java.lang.OutOfMemoryError: PermGen space

Maybe not yet qualified on Juno?

Hi Kevin,

Yes, the Scala IDE for Eclipse plugin itself isn't qualified for Juno.
ScalaTest for Scala IDE is a plugin into the Scala IDE for Eclipse. So
many levels of plugin. Anyway, just for the heck of it you might try
bumping the memory size of the JVM. The other things are fine.
Discovery starting is actually a stray println which we should have
removed, and the -p is just a deprecation warning. -p still works
fine. So the actual problem you hit is you ran out of memory.

Thanks Bill. I tried bumping up "permgen" to 1gig but no luck. Same problem.  WIll wait for official support but it looks good.

BTW I've been using the nightly builds of Eclipse IDE for Juno for several week now with nary a problem, and steadily improving feature set. Looking good.

Hi Kevin, 

Just a quick update, the Juno Scala IDE source doesn't seems to compile against ScalaTest plugin yet, see https://groups.google.com/forum/?fromgroups#!msg/scala-ide-dev/jdy3D2pfs5w/IuoKJNwlzTAJ , it is missing a pull request (which is in master already), and I think we perhaps we need a different maven profile to build for Juno, like we use different profile to build for 2.0.2 and nightly (see 'Building' section in https://github.com/scalatest/scalatest-eclipse-plugin), I'll try to check with luc.

Cheers, 

Chee Seng

Hi Kevin,

Just to double check, did you add the permgen setting to the Run Configuration screen (under Arguments tab, VM arguments)?

Cheers,

Chee Seng

[Kevin Esler]

Bingo! Thanks Chee Seng. Adjusting permgen on the Run Config got it to work. All my tests are now running in Juno. Thanks for the help.

[Bill Venners]

Hi Kevin,

That's great. Thanks for letting us know.

Hi Kevin, 

Great to hear that it is working on Juno!

[Bill Venners]

Hi Kevin,

And by the way, please tell us about your experience with the plugin.
We appreciate any bug reports, suggestions for improvements, and
general comments too.

Thanks.

Is there a release of the Scalatest Eclipse plugin for 2.10? I did
try the 2.9 version, but it doesn't do anything (no run as ->
scalatest anywhere I can see, for example).

Hi James, 

Unfortunately we don't have one built for juno deployed.  Last time I checked it seems that the Scala IDE Juno branch is missing a pull request that needs a little tweak for the plugin to compile correctly:-

https://groups.google.com/forum/?fromgroups=#!msg/scala-ide-dev/jdy3D2pfs5w/IuoKJNwlzTAJ  

Not sure if they had merged the missing pull request in by now, I'll give it a try again when possible.

Hope this helps for now.

Thanks!

Best Regards, 

Chee Seng

Sorry, I didn't mean for Juno, I meant for Indigo with the 2.10 IDE,
not the 2.9.

[Chee Seng Chua]

Ah I see, I never try to build with that branch before, probably worth trying.  I'll try myself soon.

Thanks!
