Failed CUnit test in 2.5.12 and 3.0.8

[Max Kosmach]

Hi, cyrus imap devs!

I'm trying to build 2.5.12 and 3.0.8 cyrus imapd and in both versions I have same problems with backend suite:

Suite: backend
  Test: badhost ...passed
  Test: badservice ...passed
  Test: sasl_plain ...Server failed to find requested SASL mechanism "PLAIN"
FAILED
    1. ./cunit/backend.testc:198  - CU_ASSERT_PTR_NOT_NULL_FATAL(be)
  Test: sasl_digestmd5 ...Server failed to find requested SASL mechanism "DIGEST-MD5"
FAILED
    1. ./cunit/backend.testc:265  - CU_ASSERT_PTR_NOT_NULL_FATAL(be)
  Test: multiline_caps ...Server failed to find requested SASL mechanism "PLAIN"
FAILED
    1. ./cunit/backend.testc:314  - CU_ASSERT_PTR_NOT_NULL_FATAL(be)
  Test: oneline_caps ...Server failed to find requested SASL mechanism "PLAIN"
FAILED
    1. ./cunit/backend.testc:314  - CU_ASSERT_PTR_NOT_NULL_FATAL(be)
  Test: starttls ...FAILED
    1. ./cunit/backend.testc:408  - CU_ASSERT_PTR_NOT_NULL_FATAL(be)

Is this correct behavior and I can ignore this?

PS. strace show thak this test search nonexistent testserver.conf file -
