JUnit Assert with BigDecimal

Question

I want to use assert between 2 two decimal, I use this:

BigDecimal bd1 = new BigDecimal (1000);
BigDecimal bd2 = new BigDecimal (1000);
org.junit.Assert.assertSa         


        

Answer 1

bd1 and bd2 are two different objects, and since assertSame checks the object reference using the == operator, you're getting that message, see the docs:

Asserts that two objects refer to the same object. If they are not the same, an AssertionError without a message is thrown.

You should use assertEquals instead, it checks that the two objects are equal - which is what you want.

Note that comparing two BigDecimal objects using the == operator will work as long as their values are cached (for 0 through 10) values.
