Cannot mock constructor in instrumented test

[SekoiaTree]

Prerequisites

Please answer the following questions for yourself before submitting an issue.

• I am running the latest version
• I checked the documentation and found no answer
• I checked to make sure that this issue has not already been filed (pretty sure but not 100%)

Expected Behavior

mockkConstructor should work on Android 13.

Current Behavior

Newly constructed objects are never spied on.

Failure Information (for bugs)

None visible; the objects simply do not run any every code, and simply function normally.

Steps to Reproduce

Define a class in your android package:

class MockCls {
  fun add(a: Int, b: Int) = a + b
}

In an instrumented test, mock the class' constructor, then create a new instance and print it:

mockkConstructor(MockCls::class)

every { anyConstructed<MockCls>().add(1, 2) } returns 4
println(MockCls())
assertEquals(4, MockCls().add(1, 2)) // note new object is created

The mocked object will not actually be mocked/spied, and the assertion will fail.

Context

Please provide any relevant information about your setup. This is important in case the issue is not reproducible except for under certain conditions.

• MockK version: 1.13.10
• OS: Android 13.0 Tiramisu
• Kotlin version: 1.9.0
• JDK version: Unknown, not sure how to check that on android
• JUnit version: 4.13.2
• Type of test: android instrumented test

Minimal reproducible code (the gist of this issue)

// In main app
package io.mockk.gh

class MockCls {
  fun add(a: Int, b: Int) = a + b
}

// In test package

package io.mockk.gh

import io.mockk.every
import io.mockk.mockk
import org.apache.kafka.common.KafkaFuture
import kotlin.test.Test

class Issue69Test {

    @Test
    fun test() {
        mockkConstructor(MockCls::class)

        every { anyConstructed<MockCls>().add(1, 2) } returns 4
        assertEquals(4, MockCls().add(1, 2)) // note new object is created. Test fails.
    }
