How to exclude specific results from dir

I have a series of folders:

S1

A1

A1b1

A1b2

A1b1_test

A2

A2b1

A2b2

A2b3_test

...

I have written a script to collect the different levels and their contents for processing, but I have having a difficult time removing the _test folders. Is there any simple way I can exclude the folders with the _test suffix (_test will be a constant suffix)? If I absolutely have to I can loop through, determine the number following A and b and do something like the following, but it is not preferred:

A1 = dir('A*');
A1 = A1(~ismember({A1.name},{'.','..'}));

% Preferred method, if possible
A1 = A1(~ismember({A1.name},{'*_test'}));

% If absolutely necessary
*detect appropriate A#b# configuration*
A1 = A1(~ismember({A1.name},{sprintf('A%ib%i_test',A#,b#)}));

Please excuse the naming convention, it is for representative purposes only.

C = {'A1b1';'A1b2';'A1b1_test'};
cellfun(@mkdir,C)
S = dir('./*');
S.name

ans = '.'

ans = '..'

ans = 'A1b1'

ans = 'A1b1_test'

ans = 'A1b2'

S(ismember({S.name},{'.','..'})) = [];
S(endsWith({S.name},'_test')) = [];
S.name

ans = 'A1b1'

ans = 'A1b2'
