How do you run tests?

  1. Created test and ran pytest
  2. Imported formula from series module to test_series module
  3. Run pytest
  4. Fleshed out formula in series module
  5. Run pytest
    • If failed, tweak check for error and refactor accordingly
      • GOOGLE, PEER, TA
    • If Pass, proceed to next formula.

Class notes

  1. Define functions to 'skip test'
  2. Find first error, which is a typeError: read_template() takes 0 position arguments but 1 was given
  3. Now, AssertionError: assert None == 'It was {Adjective} and {Adjective} {Noun}.'
  4. Look at test and see what it is looking for.
  5. return that to pass.
  6. provide .txt file # for first test
  7. read()
    • there is still white space, use strip to git rid.
  8. Repeat steps 1 -5 for next test
  9. return tuple, but there was an error of an extra parenthesis, so delete outer parenthesis
  10. iterate through the string

iterate character by character

for char in template:
   if not capturing:
      stripped += char
      if char == "{":
         capturing = True
   else: 
      if char == "}":
         stripped += char
         # more to do
      else:
         capture += char
         parts.append(capture)
         capture = ""
         capturing = False
      else:
         capture += char

when in the mode of iterating, create capturing var and assign it to false.

capture = ""

some_tuple = ("a",1, True) # as soon as you use that comma, it becomes a tuple.

Any tests of note?

def parse_template required to use regex. Regex made it INSANELY harder. I needed a lot of hand holding on this on.

def test_read_template_raises_exception_with_bad_path threw me for a quick loop.
