Hi Honghai,
Just a comment. Mark is correct but this is not the way to do it if
you're performing unit tests. A unit test *must* be independent from
another one. For each test, you must supply whatever initialization is
needed.
This is not a valid unit test:
public void testMinus() throws Exception {
int diff = ejb2.minus(sum, 3);
assertEquals(2, diff);
}
A valid one is :
public void testMinus1() throws Exception {
int diff = ejb2.minus(5, 3);
assertEquals(2, diff);
}
public void testMinus2() throws Exception {
int diff = ejb2.minus(2, 3);
assertEquals(-1, diff);
}
for example.
Hope it helps,
-Vincent
