S
- the "self" type of this assertion class. Please read "Emulating
'self types' using Java Generics to simplify fluent API implementation" for more details.A
- the type of the "actual" value.public interface NumberAssert<S extends NumberAssert<S,A>,A extends Number>
Number
s.Modifier and Type | Method and Description |
---|---|
S |
isBetween(A start,
A end)
Verifies that the actual value is in [start, end] range (start included, end included).
|
S |
isCloseTo(A expected,
Offset<A> offset)
Verifies that the actual number is close to the given one within the given offset.
If difference is equal to offset value, assertion is considered valid. |
S |
isNegative()
Verifies that the actual value is negative.
|
S |
isNotNegative()
Verifies that the actual value is non negative (positive or equal zero).
|
S |
isNotPositive()
Verifies that the actual value is non positive (negative or equal zero).
|
S |
isNotZero()
Verifies that the actual value is not equal to zero.
|
S |
isPositive()
Verifies that the actual value is positive.
|
S |
isStrictlyBetween(A start,
A end)
Verifies that the actual value is in ]start, end[ range (start excluded, end excluded).
|
S |
isZero()
Verifies that the actual value is equal to zero.

Example with double:
// assertions will pass:
assertThat(8.1).isCloseTo(new Double(8.0), within(0.2));
// you can use offset if you prefer
assertThat(8.1).isCloseTo(new Double(8.0), offset(0.2));
// if difference is exactly equals to the offset (0.1), it's ok
assertThat(8.1).isCloseTo(new Double(8.0), within(0.1));
// assertion will fail
assertThat(8.1).isCloseTo(new Double(8.0), within(0.01));
