    • isCloseTo

      public SELF isCloseTo(BigInteger expected, Offset<BigInteger> offset)
      Verifies that the actual number is close to the given one within the given offset.

      When abs(actual - expected) == offset value, the assertion:

      Breaking change since 2.9.0/3.9.0: using Assertions.byLessThan(BigInteger) implies a strict comparison, use Assertions.within(BigInteger) to get the old behavior.

      Example: 

       import static org.assertj.core.api.Assertions.within;

 final BigInteger eight = new BigInteger("8");
 final BigInteger ten =  BigInteger.TEN;

 // valid assertion
 assertThat(eight).isCloseTo(ten, within(new BigInteger("3")));
 assertThat(eight).isCloseTo(ten, byLessThan(new BigInteger("3")));

 // if difference is exactly equals to given offset value, it's ok
 assertThat(eight).isCloseTo(ten, within(new BigInteger("2")));
 // ... but not with byLessThan which implies a strict comparison
 assertThat(eight).isCloseTo(ten, byLessThan(new BigInteger("2")));

 // assertions will fail:
 assertThat(eight).isCloseTo(ten, within(BigInteger.ONE));
 assertThat(eight).isCloseTo(ten, byLessThan(BigInteger.ONE));
      Specified by:
      isCloseTo in interface NumberAssert<SELF extends AbstractBigIntegerAssert<SELF>,BigInteger>
      Parameters:
      expected - the given number to compare the actual value to.
      offset - the given positive offset.
      Returns:
      this assertion object.
      Throws:
      NullPointerException - if the given offset is null.
      NullPointerException - if the expected number is null.
      AssertionError - if the actual value is not close to the given one.
      Since:
      2.7.0 / 3.7.0

    • isNotCloseTo

      public SELF isNotCloseTo(BigInteger expected, Offset<BigInteger> offset)
      Verifies that the actual number is not close to the given one by less than the given offset.

      When abs(actual - expected) == offset value, the assertion:

      Breaking change since 2.9.0/3.9.0: using Assertions.byLessThan(BigInteger) implies a strict comparison, use Assertions.within(BigInteger) to get the old behavior.

      Examples: 

       import static org.assertj.core.api.Assertions.byLessThan;

 final BigInteger eight = new BigInteger("8");
 final BigInteger ten =  BigInteger.TEN;

 // this assertion succeeds
 assertThat(eight).isNotCloseTo(ten, byLessThan(BigInteger.ONE));
 assertThat(eight).isNotCloseTo(ten, within(BigInteger.ONE));

 // diff == offset but isNotCloseTo succeeds as we use byLessThan
 assertThat(eight).isNotCloseTo(ten, byLessThan(new BigInteger("2")));

 // the assertion fails as the difference is equal to the offset value and we use 'within'
 assertThat(eight).isNotCloseTo(ten, within(new BigInteger("2")));
 // the assertion fails if the difference is greater than the given offset value
 assertThat(eight).isNotCloseTo(ten, within(new BigInteger("3")));
 assertThat(eight).isNotCloseTo(ten, byLessThan(new BigInteger("3")));
      Specified by:
      isNotCloseTo in interface NumberAssert<SELF extends AbstractBigIntegerAssert<SELF>,BigInteger>
      Parameters:
      expected - the given number to compare the actual value to.
      offset - the given positive offset.
      Returns:
      this assertion object.
      Throws:
      NullPointerException - if the given offset is null.
      NullPointerException - if the expected number is null.
      AssertionError - if the actual value is close to the given one within the offset value.

       // frodo and sam are instances of Character with Hobbit race (obviously :).
 // raceComparator implements Comparator<Character>
 assertThat(frodo).usingComparator(raceComparator).isEqualTo(sam);
