I am handling transactions in Spring boot 2.7 manually:

dataHeader = transactionTemplate.execute(status -> {
    final var doc = findDoc(document);
    return saveReport(doc);
});

private Doc findDoc(DocumentDto document) {
    return docRepository.findByDocType(document.getType(), document.getId()), document.getReport()).get(0);
}

I found this answer hot to test such case, so I wrote this:

when(docRepository.findByDocType(any(), any(), any())).thenReturn(List.of());
when(transactionTemplate.execute(any(TransactionCallback.class)))
        .then(invocation -> ((TransactionCallback<ReportDocMapping>) invocation.getArgument(0))
                .doInTransaction(any(TransactionStatus.class)));

var log = LoggerWithMemoryFactory.getBufferedLoggerApi(DocService.class);
final var actual = logEvent.getMessage().getStringPayload();
if (!actual.contains(expected)) {
    var message = String.format("expected: '%s' in '%s'", expected, actual);
    throw new AssertionFailedError(message, expected, actual);
}

AFAIK I am not mixing any() matchers with values (like “X” or 10L). But still my test fails on wrong number of matchers for docRepository.findByDocType.

org.mockito.exceptions.misusing.InvalidUseOfMatchersException: 
Invalid use of argument matchers! 3 matchers expected, 1 recorded

For curiosity, this works well in a debugger when I put a breakpoint before docRepository.findByDocType.

I found this Mockito ticket, which looks relevant but I did not understand it and I don’t know how to apply it to my situation.
