Method Detail
-
isPresent
public void isPresent()
Fails if theOptionalDouble
is empty or the subject is null.
-
isEmpty
public void isEmpty()
Fails if theOptionalDouble
is present or the subject is null.
-
hasValue
public void hasValue(double expected)
Fails if theOptionalDouble
does not have the given value or the subject is null. This method is not recommended when the code under test is doing any kind of arithmetic, since the exact result of floating point arithmetic is sensitive to apparently trivial changes. More sophisticated comparisons can be done usingassertThat(optional.getAsDouble())…
. This method is recommended when the code under test is specified as either copying a value without modification from its input or returning a well-defined literal or constant value.

optionalDoubles
@Deprecated public static Subject.Factory<OptionalDoubleSubject,java.util.OptionalDouble> optionalDoubles()
Deprecated.Instead ofabout(optionalDoubles()).that(...)
, use justthat(...)
. Similarly, instead ofassertAbout(optionalDoubles()).that(...)
, use justassertThat(...)
.Obsolete factory instance. This factory was previously necessary for assertions likeassertWithMessage(...).about(optionalDoubles()).that(optional)....
. Now, you can perform assertions like that without theabout(...)
call.
