Example 62 with JavaClass

use of com.tngtech.archunit.core.domain.JavaClass in project ArchUnit by TNG.

the class ClassFileImporterAccessesTest method identifies_call_origin_if_signature_and_descriptor_deviate.

@Test
public void identifies_call_origin_if_signature_and_descriptor_deviate() {
    // Kotlin inline functions cause the creation of extra classes where the signature of the respective method shows
    // the real types while the descriptor shows the erased types. The erasure of the real types from the signature
    // does then not match the descriptor in some cases.
    // 
    // The file `MismatchBetweenDescriptorAndSignature.class` is a byproduct of the following source code:
    // --------------------
    // package com.example
    // 
    // object CrashArchUnit {
    // fun useInlineFunctionCrashingArchUnit(strings: List<String>) = strings.groupingBy { it.length }
    // }
    // --------------------
    // With the current Kotlin version this creates a synthetic class file `CrashArchUnit$useInlineFunctionCrashingArchUnit$$inlined$groupingBy$1.class`
    // which has been copied and renamed to `MismatchBetweenDescriptorAndSignature.class`.
    JavaClass javaClass = getOnlyElement(new ClassFileImporter().importLocations(singleton(Location.of(relativeResourceUri(getClass(), "testexamples/MismatchBetweenDescriptorAndSignature.class")))));
    // this method in the problematic compiled class has a mismatch between return type of descriptor and signature
    assertThat(javaClass.getMethod("keyOf", Object.class).getMethodCallsFromSelf()).isNotEmpty();
