You can use it like this to launch all the
test scripts in order:

$ cd test
$ make
 rm -r test-results
 *** t0010-basic-commands.sh ***
 ok 1 - current dir is writable
 ok 2 - ipfs version succeeds
 ok 3 - ipfs version output looks good
 ok 4 - ipfs help succeeds
 ok 5 - ipfs help output looks good
 # passed all 5 test(s)
 1..5
 ./test-aggregate-results.sh
 fixed   0
 success 5
 failed  0
 broken  0
 total   5

Or you can just run one test like this:

$ make t0010-basic-commands.sh
 *** t0010-basic-commands.sh ***
 ok 1 - current dir is writable
 ok 2 - ipfs version succeeds
 ok 3 - ipfs version output looks good
 ok 4 - ipfs help succeeds
 ok 5 - ipfs help output looks good
 # passed all 5 test(s)
 1..5
