As of the morning of February 16, it should be downloaded from the release page on Sourceforge. The web site, http://junit.org/, has not been updated yet but will surely be updated soon; when this happens, this news post will be altered to reflect the correct information.
As the use of annotations should indicate, this release of JUnit is only for JSE 5 (or later).
The basic form of a test, using the annotation framework, now looks like this (in a sample from the JUnit 4.0 cookbook, which is part of the download):
@Test public void simpleAdd() {There are other capabilities, such as specifying expected exception conditions, pre- and post-conditions, and more.
Money m12CHF= new Money(12, "CHF");
Money m14CHF= new Money(14, "CHF");
Money expected= new Money(26, "CHF");
Money result= m12CHF.add(m14CHF);
assertTrue(expected.equals(result));
}
