Answer 1

You cannot directly print by using system.out.println or using logger api while using JUnit. But if you want to check any values then you simply can use

Assert.assertEquals("value", str);

It will throw below assertion error:

java.lang.AssertionError: expected [21.92] but found [value]

Your value should be 21.92, Now if you will test using this value like below your test case will pass.

 Assert.assertEquals(21.92, str);
