Method

doubleassertAboveEqual(final double number, final double value)
assert Above Equal 
if (number < value) {
    return value;
return number;
voidassertApproxEquals(double a, double b, double relative, double absolute)
assert Approx Equals 
assertApproxEquals(a, b, relative, absolute, null);
booleanassertArrayEquals(double[] p1, double[] p2, double eps)
assert Array Equals 
if (p1.length != p2.length) {
    return false;
for (int i = 0; i < p1.length; i++) {
    if (Math.abs(p1[i] - p2[i]) > eps) {
        return false;
return true;
voidassertArrayLengthEqual(Object[] array, String name, Object[] array1, String name1)
Check if the lengths of the two arrays are equal. 
if (array.length != array1.length) {
    throw new IllegalArgumentException("The length of " + name + " should be the same as that of " + name1);
booleanassertCharacterArraysEqual(char[] first, char[] second)
Asserts that the specified first array of characters is identical to the specified second array of characters. 
int firstLength = first.length;
int secondLength = second.length;
if (firstLength != secondLength) {
    return false;
for (int index = 0; index < firstLength; index++) {
    char firstCharacter = first[index];
    char secondCharacter = second[index];
...
voidassertDatesEqual(Calendar first, Calendar second)
assert Dates Equal 
if (first == null && second != null) {
    throw new AssertionError("dates are not equal. first is null, second is not");
} else if (first != null && second == null) {
    throw new AssertionError("dates are not equal. second is null, first is not");

...
booleanassertEqual(final double d1, final double d2, final double precisionRange)
Asserts if the given two doubles are equal within the given precision range by the operation: 
 Math.abs(d1 - d2) < precision
. 
return Math.abs(d1 - d2) < precisionRange;

assert Equality 
if (!original.equals(equal)) {
    throw new AssertionError("Objects where not equal " + original + " != " + equal);
if (original.hashCode() != equal.hashCode()) {
    throw new AssertionError("Equal objects did not have same hash :" + original + "(" + original.hashCode()
            + ")" + " " + equal + "(" + equal.hashCode() + ")");
