test my equals using junit 4

Hi,

Is there a simple way to unit test ( using junit 4) the following
code:

@[EMAIL PROTECTED]
 boolean equals(Object obj) {
		if (this == obj)
			return true;
		if (obj == null)
			return false;
		if (getClass() != obj.getClass())
			return false;
		final DistributionGroup other = (DistributionGroup) obj;
		if (address == null) {
			if (other.address != null)
				return false;
		} else if (!address.equals(other.address))
			return false;
		if (description == null) {
			if (other.description != null)
				return false;
		} else if (!description.equals(other.description))
			return false;
		if (id == null) {
			if (other.id != null)
				return false;
		} else if (!id.equals(other.id))
			return false;
		if (name == null) {
			if (other.name != null)
				return false;
		} else if (!name.equals(other.name))
			return false;
		if (noAnswerTimeout == null) {
			if (other.noAnswerTimeout != null)
				return false;
		} else if (!noAnswerTimeout.equals(other.noAnswerTimeout))
			return false;
		if (open != other.open)
			return false;
		if (overflowWhenBusy == null) {
			if (other.overflowWhenBusy != null)
				return false;
		} else if (!overflowWhenBusy.equals(other.overflowWhenBusy))
			return false;
		if (overflowWhenClosed == null) {
			if (other.overflowWhenClosed != null)
				return false;
		} else if (!overflowWhenClosed.equals(other.overflowWhenClosed))
			return false;
		if (overflowWhenNoAgents == null) {
			if (other.overflowWhenNoAgents != null)
				return false;
		} else if (!overflowWhenNoAgents.equals(other.overflowWhenNoAgents))
			return false;
		if (announcement != other.announcement)
			return false;
		if (sup****tAgents == null) {
			if (other.sup****tAgents != null)
				return false;
		} else if (!sup****tAgents.equals(other.sup****tAgents))
			return false;
		return true;
	}
