java.lang.IllegalArgumentException: Please don't pass mock here. Spy is not allowed on mock. for ParameterizedTest

I have following test:

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.MOCK)
@WebAppConfiguration
class MyTest {
    @MockitoSpyBean
    protected lateinit var ldapConnectionPoolHolder: LdapConnectionPoolHolder
    
    @BeforeEach
    fun setup() {
        connectionPoolSpy = spy(ldapConnectionPoolHolder.getConnectionPool())
        doReturn(connectionPoolSpy).whenever(ldapConnectionPoolHolder).getConnectionPool()
        connectionSpy = spy(connectionPoolSpy.getConnection()) // this line leads to error sometimes
        doReturn(connectionSpy).whenever(connectionPoolSpy).getConnection()
    }

    @ParameterizedTest("...")
    @MethodSource("withoutCookiesSuccessScenarios")
    fun myTest(...) {
    }

for even iterations I see an error:

java.lang.IllegalArgumentException: Please don't pass mock here. Spy is not allowed on mock.

    at org.mockito.Mockito.spy(Mockito.java:2246)
    at org.mockito.kotlin.SpyingKt.spy(Spying.kt:52)
enter code here

enter image description here

I tried to do Mockito.reset(connectionPoolSpy, connectionSpy)

in the end of the test but it doesn't help

The solution is adding

@DirtiesContext(classMode = DirtiesContext.ClassMode.BEFORE_EACH_TEST_METHOD)

So test class definition will look like:

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.MOCK)
@WebAppConfiguration
@DirtiesContext(classMode = DirtiesContext.ClassMode.BEFORE_EACH_TEST_METHOD)
class MyTest {
