Comparing arrays in JUnit assertions, concise built-in way?
Use org.junit.Assert's method assertArrayEquals:
import org.junit.Assert;...Assert.assertArrayEquals( expectedResult, result );If this method is not available, you may have accidentally imported the Assert class from junit.framework.
You can use Arrays.equals(..):
assertTrue(Arrays.equals(expectedResult, result));
I prefer to convert arrays to strings:
Assert.assertEquals( Arrays.toString(values), Arrays.toString(new int[] { 7, 8, 9, 3 }));this way I can see clearly where wrong values are. This works effectively only for small sized arrays, but I rarely use arrays with more items than 7 in my unit tests.
This method works for primitive types and for other types when overload of toString returns all essential information.
