How do I test the methods in the java class wordOf32Bits_test that I made in class wordOf32Bits. I included the class realisticBit for reference.

public class wordOf32Bits{

private bit[] bits;

// constructor

public wordOf32Bits() {

// allocate bits array

bits = new bit[32];

// initialise with 0 bits

for (int i = 0; i < 32; i++) {

bits[i] = new bit();

//bits.getValue();

}

}

public wordOf32Bits(bit[] other) {

bits = new bit[32];

for (int i = 0; i < 32; i++) {

bits[i] = new bit(other[i].getValue());

//this.bits[i] = new bit();

}

}

public bit getBit(int i) {

// check if i is in range

if (i < 0 || i >= 32) {

// i is out of range

// return null

throw new IllegalArgumentException("Argument i out of range");

}

// else i is in range

return bits[i];

}

public void setBit(int i, bit value) {

// sets a given bit

// only update if i in range

if (i >= 0 && i < 32) {

bits[i] = value;

} else {

throw new IllegalArgumentException("Argument i out of range");

}

}

public wordOf32Bits and(wordOf32Bits other){

wordOf32Bits word = new wordOf32Bits();

for(int i = 0; i < 32; i++) {

word.setBit(i, this.bits[i].and(other.bits[i]));

return word;

}}

//THIS IS WHAT NEEDS HELP

public class wordOf32Bits_test{

wordOf32Bits wordOf32Bits = new wordOf32Bits();

private bit[] bits;

public static void main(String[] args) throws Exception {

runtests();

}

public void getBitTest() throws Exception{

}

public void setBitTest() throws Exception{

}

public void wordOf32BitsAndTest() throws Exception{

}

public static void runtests() throws Exception {

}

}
