How to specify multiple exclusion filters in --gtest_filter?

You group the patterns in the form --gtest_filter=POSTIVE_PATTERNS[-NEGATIVE_PATTERNS]

So in this case, you want --gtest_filter=-ABC.*:BCD.*

See https://blogs.msdn.microsoft.com/taxiahou/2013/07/30/the-usage-of-running-a-subset-of-tests-in-google-test-framework-gtest_filter/. You can find a clear example there.

Exclusions are identified by '-' sign. You can say multiple seperated by :. no need of repeating - with :.

--gtest_filter=-*str* :This will run tests that don't contain string "str".

--gtest_filter=-*str1*:*str2* :This will run tests that don't contain either "str1" or "str2":

--gtest_filter=*str*:-*str1*:*str2* :This will run tests that contain str and that do not contain either str1 or str2.

So, anything followed by '-' will be counted for exclusion list.

So, in your case it will be --gtest_filter=-ABC.*:BCD.*
