Testing Java code with Groovy under Intellij: unable to resolve class GroovyTestCase

Question

I need to write a short test for some Java code. I used CTRL+SHIFT+T to generate one with IntelliJ, and selected "Groovy JUnit" as the testing library, then wrote the following test:

package util class FibonacciHeapTest extends GroovyTestCase {     FibonacciHeap<Integer> heap      void setUp() {         super.setUp()         heap = new FibonacciHeap<>()     }      void testAddInOrder() {         testForItems 1..1000     }       private void testForItems(Range<Integer> items) {         items.each {heap << it}         assertEquals heap.size, items.to         items.each {assertEquals heap.remove(), it}     } } 

However, when I right click on the test case in the project window, I don't get the "Run All Tests" option that I normally do with JUnit tests, and the compiler throws the following error:

Information:2/4/15 8:15 PM - Compilation completed with 2 errors and 0 warnings in 2 sec /home/patrick/IdeaProjects/hackerrank/src/test/java/util/FibonacciHeapTest.groovy Error:(3, 1) Groovyc: unable to resolve class util.FibonacciHeap Error:(9, 1) Groovyc: unable to resolve class GroovyTestCase 

Trying to import GroovyTestCase or FibonacciHeap manually causes the same error. IntelliJ does not add any import statements when I let autocomplete finish the names for me, like it usually would with Java code.

What am I doing wrong?

This worked for me :

• Open Gradle window (on right side in my case)
• Click on refresh button
• Done
