Question

Problem Set 3 testing - target strings and keys

Answer 1

I'll post some test strings for the function in Problem Set 3 (ps3d)

# should match one sub strings and exclude exact matches
# Test 0 : test for exact match
# Test 1 : test for one sub and more than one sub
# for ex. for 'atg', it should match 'xtg', 'axg' and 'atx'
# and not 'atg', 'axtg', 'atxg' etc
# Test 2 : test for two and more subs
# Test 3 : test for overlap
# for ex for 'atta' it should match 'xttaxta' => (0, 3)
# Test 4 : test if string exist at all
# Test 5 : test for repeat
#

target0 = 'atgaatgcatggatgtaaatgcag' # exact match for atg (0, 5, 9, 13, 19)
# 012345678901234567890123
target1 = 'atgaxtgcaxggatxtaaatgcag' # key1 'atg' (4, 8, 12)
# 012345678901234567890123
# next string features overlap
target2 = 'attagxttataxtatxattxgcag' # key2 'atta' (5, 10, 13, 16)
# 012345678901234567890123
target3 = 'gcgcgcgcgcgcgcgcgcgcgcgc' # key3 'atgc' ()
# 012345678901234567890123
target4 = 'axaaaaaaaaaaaaaaaaaaaaaa' # key41 'aaaa' (0, 1) and key42 'tttt' ()
# 012345678901234567890123

# key strings
key0 = 'atg'
key1 = 'atg'
key2 = 'atta'
key3 = 'atgc'
key41 = 'aaaa'
key42 = 'tttt'


HAPPY TESTING
