In the beginning there was only mysql-test/t. Then MySQL developers felt 
the need to organize tests in suites, so they created mysql-test/suite, 
which has one sub directory per suite.
If you simply run mysql-test-run it will print
"Using suites: 
main,sys_vars,binlog,federated,rpl,innodb,innodb_fts,perfschema,funcs_1,opt_trace,parts", 
these are the suites which it tests by default.
"main" is special: it means the tests in mysql-test/t.
You can specify what suites you want:
./mtr --suite=main,binlog
