How to check multiple exceptions with one JUnit Method?
<p>i have this code in my program which is needed to be tested with jUnit</p>

<pre><code> void deleteCustomer(String name) throws UnknownCustomerException,
        AccountNotEmptyException {
    if (name == null) {
        throw new NullPointerException();
    } else if (!exists(name)) {
        throw new UnknownCustomerException();
    } else if (getCustomer(name).deletable()) {
        customerList.remove(getCustomer(name));
    }
}
</code></pre>

<p>I thought i can test it in one JUnit method like</p>

<pre><code>   @Test
public void createCustomer(){
    System.out.println("createCustomerTest");
    try {
        element.createCustomer(null);
        //fail("Expected an IndexOutOfBoundsException to be thrown");
    } catch (NullPointerException anIndexOutOfBoundsException) {
        assertTrue(anIndexOutOfBoundsException.getMessage().equals("NullPointerException"));
    }
}
</code></pre>

<p>As you can see I already tried unsuccessfully to implement the NPE. 
How can I check for several Exceptions in one JUnit Method? I checked some How-To's in the web but failed with that too.</p>
