+### Custom matchers
+
+Example of a custom matcher that compares list without order:
+
+```kotlin 
+
+@Test
+fun test() {
+    class MockCls {
+        fun op(a: List<Int>) = a.reversed()
+    }
+
+    val mock = mockk<MockCls>()
+
+    every { mock.op(any()) } returns listOf(5, 6, 9)
+
+    println(mock.op(listOf(1, 2, 3)))
+
+    verify { mock.op(matchListWithoutOrder(3, 2, 1)) }
+
+}
+
+data class ListWithoutOrderMatcher<T>(
+    val expectedList: List<T>,
+    val refEq: Boolean
+) : Matcher<List<T>> {
+    val map = buildCountsMap(expectedList, refEq)
+
+    override fun match(arg: List<T>?): Boolean {
+        if (arg == null) return false
+        return buildCountsMap(arg, refEq) == map
+    }
+
+    private fun buildCountsMap(list: List<T>, ref: Boolean): Map<Any?, Int> {
+        val map = mutableMapOf<Any?, Int>()
+
+        for (item in list) {
+            val key = when {
+                item == null -> nullKey
+                refEq -> InternalPlatform.ref(item)
+                else -> item
+            }
+            map.compute(key, { _, value -> (value ?: 0) + 1 })
+        }
+
+        return map
+    }
+
+    override fun toString() = "matchListWithoutOrder($expectedList)"
+
+    @Suppress("UNCHECKED_CAST")
+    override fun substitute(map: Map<Any, Any>): Matcher<List<T>> {
+        return copy(expectedList = expectedList.map { map.getOrDefault(it as Any?, it) } as List<T>)
+    }
+
+    companion object {
+        val nullKey = Any()
+    }
+}
+
+inline fun <reified T : List<E>, E : Any> MockKMatcherScope.matchListWithoutOrder(
+    vararg items: E,
+    refEq: Boolean = true
+): T = match(ListWithoutOrderMatcher(listOf(*items), refEq))

 ## Settings file
 
 To adjust parameters globaly there is a posibility to specify few settings in a resource file.
