@Test
public void testAllMatchInt() {
    for (final double[] doubleArray : testArrays) {
        final int[] array = Arrays.stream(doubleArray).mapToInt(x -> (int) Math.round(x)).toArray();
        final IntPredicate pred = x -> x > -1;
        Assert.assertEquals(MathUtils.allMatch(array, pred), Arrays.stream(array).allMatch(pred));
    }
}

    AtomicBoolean alwaysFalse2Invoked = new AtomicBoolean(false);
    AtomicBoolean[] invocationState = { alwaysTrueInvoked, alwaysTrue2Invoked, alwaysFalseInvoked, alwaysFalse2Invoked };
    IntPredicate alwaysTrue = x -> {
        alwaysTrueInvoked.set(true);
        assertEquals(x, arg);
        return true;
    };
    IntPredicate alwaysTrue2 = x -> {
        alwaysTrue2Invoked.set(true);

        return true;
    };
    IntPredicate alwaysFalse = x -> {
        alwaysFalseInvoked.set(true);
        assertEquals(x, arg);
        return false;
    };
    IntPredicate alwaysFalse2 = x -> {
        alwaysFalse2Invoked.set(true);
        assertEquals(x, arg);
        return false;
    };
    // true && true
    resetToFalse(invocationState);
    assertTrue(alwaysTrue.and(alwaysTrue2).test(arg));
    assertTrue(alwaysTrueInvoked.get() && alwaysTrue2Invoked.get());
    // true && false
    resetToFalse(invocationState);
    assertFalse(alwaysTrue.and(alwaysFalse).test(arg));
    assertTrue(alwaysTrueInvoked.get() && alwaysFalseInvoked.get());
    // false && false
    resetToFalse(invocationState);
    assertFalse(alwaysFalse.and(alwaysFalse2).test(arg));
    assertTrue(alwaysFalseInvoked.get() && !alwaysFalse2Invoked.get());
    // false && true
    resetToFalse(invocationState);
    assertFalse(alwaysFalse.and(alwaysTrue).test(arg));
    assertTrue(alwaysFalseInvoked.get() && !alwaysTrueInvoked.get());
}
