I've inherited some JUnit tests written in scala that need to be fixed to use @BeforeClass semantics. I understand that the @BeforeClass annotation must be applied to static methods only. I understand that methods defined in "companion" objects (as opposed to scala classes) are static. How can I get a test method to be called once prior to the individual instance methods in a test class?

org.junitAnnotating a public static void no-arg method with @BeforeClass causes it to be run once before any of the test methods in the class. The @BeforeClass methods of superclasses will be run before those of the current class, unless they are shadowed in the current class.
To run a test suite using JUnit in Scala IDE, open the source file of the test, right-click in it, and select Run as → JUnit Test. You can re-run your test using the launch configuration which is automatically created. Check the Eclipse documentation for more details.
Before and BeforeClass in JUnit The function @Before annotation will be executed before each of test function in the class having @Test annotation but the function with @BeforeClass will be execute only one time before all the test functions in the class.
The execution procedure is as follows − First of all, the beforeClass() method executes only once. The afterClass() method executes only once. The before() method executes for each test case, but before executing the test case. The after() method executes for each test case, but after the execution of test case.
object TestClass {
@BeforeClass
def stuff() {
// beforeclass stuff
}
}
class TestClass {
@Test
...
}
seems to work...
