How do I compare Integer and Long types with Junit?

How do I compare Integer and Long types with Junit ?

The result of assertThat(poiList.get(0).get("id_pk")).isEqualTo(member.getId_pk()); is:

org.opentest4j.AssertionFailedError:
expected: 1L
but was : 1
Expected :1L
Actual :1

The two types are:

log.info("getClass1: {}", poiList.get(0).get("id_pk").getClass());
         log.info("getClass2: {}", member.getId_pk().getClass());

2021-09-30 15:29:08.904 INFO 19504 --- [ main] c.p.i.domain.item.ItemServiceTest : getClass1: class java.lang.Integer
2021-09-30 15:29:08.904 INFO 19504 --- [ main] c.p.i.domain.item.ItemServiceTest : getClass2: class java.lang.Long

How can I compare 1 and 1L to be equal?

best regards

As all answers show, you need to change one param's type. Maybe both change them to String is also a good idea.

 assertThat(String.valueOf(1L)).isEqualTo(String.valueOf(1))

How about this:

assertThat(new BigDecimal(1)).isEqualTo(new BigDecimal(1L));

Two ways:

  1. Java's Long class has an .intValue() method returning an int.

  2. Java's Integer class has a .longvalue() method.

I would recommend the second, as long can take a larger range of values than int.

Looks like it should be corrected at entity level because if we say poiList.get(0).get("id_pk") is equal to member.getId_pk() then logically datatype for them should also be same.

As the preferred solution you should correct it entity level.

But if you still want to assert it then convert int to long first and then assert on that.

poiList.get(0).get("id_pk").longValue()

You can convert Integer to Long via java.lang.Integer#longValue:

assertThat(poiList.get(0).get("id_pk").longValue()).isEqualTo(member.getId_pk());

BUT beware of Null pointers, if poiList.get(0).get("id_pk") is null then a Null Pointer Exception will be thrown!
