eclipse unit tests don't support 'assert'? [message #503079]

Currently within a maven project, within a unit test, if I run [run as -> junit test]

it appears that
assert(false)
statements don't fire (they should raise an exception)

Anybody else getting this?
[it's a command line parameter to the JVM].

Haven't seen that.

You might want to try putting some debug statements in your test to output the
JVM properties, to see if that option is getting set.

Do you get the expected output if you run the tests in Maven outside of Eclipse?

Are you talking about JUnit or Java assertions? For Java assertions to
take effect you need to launch with -ea VM argument.

You might want to try putting some debug statements in your test to output the
JVM properties, to see if that option is getting set.

It appears that eclipse is running the tests with this command line.
javaw -Dfile.encoding=Cp1252 -classpath [...] org.eclipse.jdt.internal.junit.runner.RemoteTestRunner -version 3 -port 2359 -testLoaderClass org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader -loaderpluginname org.eclipse.jdt.junit4.runtime -classNames org.familysearch.digitalarchive.dasfinderws.idis.DasServiceI DisImplTest

i.e. I don't see the -ea in there at all.

I'm unsure of any clever way to query the JVM options from within the JVM...

I do. If I run the same tests using maven from the command line, the unit tests fire. I am just scratching my head wondering why eclipse would not add -ea to the command line if I specify "run this file as junit test"

Maven runs its with -ea, netbeans runs it with -ea (because all it does is call maven on it), eclipse doesn't?

Java assertions.

Any thoughts?

Edit the launch configuration for the unit tests and add the -ea on the
arguments page.
