- Method Detail
  - isPresent
```
public void isPresent()
```
    Checks that the actual Optional contains a value.
  - isEmpty
```
public void isEmpty()
```
    Checks that the actual Optional does not contain a value.
  - hasValue
```
public void hasValue(@Nullable Object expected)
```
    Checks that the actual Optional contains the given value.
    To make more complex assertions on the optional's value, split your assertion in two:
    assertThat(myOptional).isPresent(); assertThat(myOptional.get()).contains("foo");
  - optionals
```
@Deprecated
public static Subject.Factory<OptionalSubject,Optional<?>> optionals()
```
    Deprecated.
    Instead of about(optionals()).that(...), use just that(...). Similarly, instead of assertAbout(optionals()).that(...), use just assertThat(...).
    
    Obsolete factory instance. This factory was previously necessary for assertions like assertWithMessage(...).about(paths()).that(path)..... Now, you can perform assertions like that without the about(...) call.
