Testing my twttr

In a file called twttr.py, reimplement Setting up my twttr from Problem Set 2, restructuring your code per the below, wherein shorten expects a str as input and returns that same str but with all vowels (A, E, I, O, and U) omitted, whether inputted in uppercase or lowercase.

	def main():
		...


	def shorten(word):
		...


	if __name__ == "__main__":
		main()

Then, in a file called test_twttr.py, implement one or more functions that collectively test your implementation of shorten thoroughly, each of whose names should begin with test_ so that you can execute your tests with:

	pytest test_twttr.py

Hints

• Be sure to include

    import twttr

or

	from twttr import shorten

atop test_twttr.py so that you can call shorten in your tests.

• Take care to return, not print, a str in shorten. Only main should call print.

Before You Begin

From the root of your repository execute cd 5-UnitTests So your current working directory is ...

	/5-UnitTests $:

Next execute

	mkdir test_twttr

to make a folder called test_twttr in your codespace.

Then execute

	cd `test_twttr`

to change directories into that folder. You should now see your terminal prompt as /5-UnitTests/test_twttr $. You can now execute

	code test_twttr.py

to make a file called test_twttr.py where you’ll write your program.

How to Test

To test your tests, run pytest test_twttr.py. Be sure you have a copy of a twttr.py file in the same folder. Try to use correct and incorrect versions of twttr.py to determine how well your tests spot errors:

Ensure you have a correct version of twttr.py. Run your tests by executing pytest test_twttr.py. pytest should show that all of your tests have passed. Modify the correct version of twttr.py in such a way as to create a bug. Your program might, for example, mistakenly only omit lowercase vowels! Run your tests by executing pytest test_twttr.py. pytest should show that at least one of your tests has failed.

Commit your program to GITHUB

At the /5-UnitTests/test_twttr $ prompt in your terminal:

	git add -A 

Add all changed files in the repository to be committed

	git commit -m “Upload completed test_twttr.py“

Commit all changes in the REPO with the comment “Upload completed test_twttr.py“ note: If the file is not complete, adjust the comment to describes what is being commited

	git push 

Push all changes to the REPO
