Generic Types

AutoParams is capable of generating objects of generic types, adhering to its constructor selection policy. When dealing with generic types, AutoParams employs a public constructor with arbitrary arguments for object creation. If multiple public constructors are available, the framework opts for the one with the fewest parameters.

Java

@AllArgsConstructor
@Getter
public class GenericObject<T1, T2> {
    private final T1 value1;
    private final T2 value2;
}

Kotlin

class GenericObject<T1, T2>(
    val value1: T1,
    val value2: T2
)

Java

@ParameterizedTest
@AutoSource
void testMethod(
    GenericObject<String, ComplexObject> arg1,
    GenericObject<UUID, GenericObject<String, ComplexObject>> arg2) {
}

Kotlin

@ParameterizedTest
@AutoSource
fun testMethod(
    arg1: GenericObject<String, ComplexObject>,
    arg2: GenericObject<UUID, GenericObject<String, ComplexObject>>) {
}
