I have strings like



the first 8 characters of this string will remain same however the last letter could change for next release of the software. is there anyway that i can do pattern matching in JUnit rather putting a loop for assertEquals and going through all the possible combinations?

sure you could combine assertTrue with Pattern.matches(String regex, CharSequence input)

eg.


the only thing you need to find out is the proper pattern that validates the given string.
