public class AssertionError extends Error Thrown to indicate that an assertion assertion error java has failed. The seven one-argument public constructors provided by this class ensure that the assertion error returned by assertion error pro tools the invocation: new AssertionError(expression) has as its detail message the string conversion of expression (as defined in section 15.18.1.1 of The Java™ Language Specification), regardless of the type of expression.

The code needs to return the k elements of a nearest to val. This method will throw an IllegalArgumentException if k is negative and return an array of zero length if k == 0 or if k > a.length. When I run the test case against this method, it reports: There was 1 failure: http://stackoverflow.com/questions/18578071/junit-test-case-failure-java-lang-assertionerror-expectedi12c5431-but-was 1) nearestKTest(SelectorTest) java.lang.AssertionError: expected:<[I@12c5431> but was:<[I@14b6bed> at SelectorTest.nearestKTest(SelectorTest.java:21) FAILURES!!! Tests run: 1, Failures: 1 I know this means expected didn't match actual. I just could not figure it out. :( public static int[] nearestK(int[] a, int val, int k) { int[] b = new int[10]; for (int i = 0; i < b.length; i++){ b[i] = Math.abs(a[i] - val); } Arrays.sort(b); int[] c = new int [k]; for (int i = 0; i < k; i++){ if (k < 0){ throw new IllegalArgumentException("k is not invalid!"); } else if (k == 0 || k > a.length){ return new int[0];} else{ c[i] = b[i];} } return c; } Test case: import org.junit.Assert; import static org.junit.Assert.*; import org.junit.Before; import org.junit.Test; public class SelectorTest { /** Fixture initialization (common initialization * for all tests). **/ @Before public void setUp() { } /** A test that always fails. **/ @Test public void nearestKTest() { int[] a = {2, 4, 6, 7, 8, 10, 13, 14, 15, 32}; int[] expected = {6, 7}; int[] actual = Selector.nearestK(a, 6, 2); Assert.assertEquals(expected,actual); } } java share|improve this question asked Sep 2 '13 at 17:14 catchwisdom 25117 add a comment| 2 Answers 2 active oldest votes up vote 5 down vote accepted You're comparing Ob

The module is intended for internal use by Node.js, but can be used in application code via require('assert'). However, assert is not a testing framework, and is not intended to be used as a general purpose assertion library. The API for the assert module is Locked. This means assertion error on that there will be no additions or changes to any of the methods implemented and exposed by the module. assert(value[, message])# Added in: v0.5.9 An alias of assert.ok() . const assert = require('assert'); assert(true); // OK assert(1); // OK assert(false); // throws "AssertionError: false == true" assert(0); // throws "AssertionError: 0 == true" assert(false, 'it\'s false'); // throws "AssertionError: it's false" assert.deepEqual(actual, expected[, message])# Added in: v0.1.21 Tests for deep equality between the actual and expected parameters. Primitive values are compared with the equal comparison operator ( == ). Only enumerable "own" properties are considered. The deepEqual() implementation does not test object prototypes, attached symbols, or non-enumerable properties. This can lead to some potentially surprising results. For example, the following example does not throw an AssertionError because the properties on the Error object are non-enumerable: // WARNING: This does not throw an AssertionError! assert.deepEqual(Error('a'), Error('b')); "Deep" equality means that the enumerable "own" properties of child objects are evaluated also: const assert = require('assert'); const obj1 = { a : { b : 1 } }; const obj2 = { a :
