JUnit assertions : make the assertion between floats

April 7, 2023 by Tarik

You have to provide a delta to the assertion for Floats:

Assert.assertEquals(expected, actual, delta)

While delta is the maximum difference (delta) between expected and actual for which both numbers are still considered equal.

Assert.assertEquals(0.0012f, 0.0014f, 0.0002); // true
Assert.assertEquals(0.0012f, 0.0014f, 0.0001); //false
