KotlinFixture is the attempt to bring Mark Seemann's AutoFixture for .NET to Kotlin. Its purpose is to generate full object graphs for use in test suites with a fluent API for customising the test objects during generation.

When building (or using) the current version of KotlinFixture (0.2.0) on Java 17, an exception is thrown, see stacktrace below.
This due to Java 17 counting illegal module access an error, instead of a warning JEP-403
For maven, I configured the test runner plugin (failsafe) to provide the --add-opens arguments for the affected modules.
<plugin>
<artifactId>maven-failsafe-plugin</artifactId>
<configuration>
<argLine>
--add-opens java.base/java.lang=ALL-UNNAMED
</argLine>
</configuration>
</plugin>
Latest JavaFixture solves this, so an update should fix things and make the workaround unnecessary. JUnit dependencies should also be updated.

It's not a surprise, that KotlinFixture cannot handle kotlin.collections, since it's only a wrapper for JavaFixture.
The two following example will return a java.util.ArrayList where all elements are Object:
val result = Fixture().create<List<Int>>()
val result = Fixture().create<List<Integer>>()
This will work:
val result = Fixture().create<java.util.ArrayList<Int>>()
With the new dokka plugin 1.4.x it should be possible to create a javadoc-jar in Kotlin projects using Java 11.
However, when releasing, the javadoc-jar seems to be missing, which is most likely a misconfiguration of dokka.

Disclaimer: Not sure if this is a bug - or if it's in JavaFixture or Kotlin fixture for that matter.
When I specify that Int should always be a certain value, I expect a List<Int> to contain this value at least once.
@Test
fun withType() {
val sut = SpecimenBuilder(com.github.nylle.javafixture.SpecimenBuilder(object : SpecimenType<TestObjectGeneric<String, List<Int>>>(){}, configure()))
val result = sut
.with<Int>(111111)
.create()
assertThat(result).isInstanceOf(TestObjectGeneric::class.java)
assertThat(result.u).contains(111111)
}
java.lang.AssertionError:
Expecting:
<[229551647, -2024430022, -2056851173, 462021988, -1922426415]>
to contain:
<[111111]>
but could not find:
<[111111]>
Something that indicates that this is a problem with containers (lists in this case) is that this test case works perfectly fine:
@Test
fun withType() {
val sut = SpecimenBuilder(com.github.nylle.javafixture.SpecimenBuilder(object : SpecimenType<TestObjectGeneric<String, Int>>(){}, configure()))
val result = sut
.with<Int>(111111)
.create()
assertThat(result).isInstanceOf(TestObjectGeneric::class.java)
assertThat(result.u).isEqualTo(111111)
}
