Feature summary
The method asList() should return a correctly typed list.
Example
Assume a type Bar with the filed strings: List<String>. And a type Foo with the field bar: List<Bar> (both with default getter and all-args-constructor).
class Foo {
private final List<Bar> bars;
}
class Bar {
private final List<String> strings;
}The following block is type-safe
import static java.util.Arrays.asList;
Bar bar = new Bar(asList("a","b"));
assertThat(bar)
.extracting(Bar::getStrings)
.asList()
.containsExactly("a", "b");When working with nested structures and using Assert.asList() the returned list will be of type Object.
Foo myComplexFoo = new Foo(asList(new Bar(asList("a", "b")), new Bar(asList("a", "b"))));
assertThat(myComplexFoo)
.extracting(Foo::getBars)
.asList()
.extracting(o -> ((Bar)o).getStrings())
.containsExactly(asList("a", "b"), asList("a", "b"));We had to cast the Object back to a Bar for working further with it.
The proposal creates an overload to the asList() which gets a type such that we can further assert the structure like:
Foo myComplexFoo = new Foo(asList(new Bar(asList("a", "b")), new Bar(asList("a", "b"))));
assertThat(myComplexFoo)
.extracting(Foo::getBars)
.asTypedList(Bar.class)
.extracting(Bar::getStrings)
.containsExactly(asList("a", "b"), asList("a", "b"));
