Testing my twittr

Testing my twttr

This Python program is an implementation to CS50’s Introduction to Programming with Python Week 5 - Testing my twttr Problem Set. The twttr.py program is designed to remove all vowels (both uppercase and lowercase) from a given string. To ensure that the program functions correctly, a set of tests have been implemented in the test_twttr.py file. These tests thoroughly test the shorten function, checking its behavior against various inputs.

How to Run the Tests

1. Open your terminal.

2. Navigate to the directory where you have saved both twttr.py and test_twttr.py.

   cd path/to/your/directory
   

3. Run the tests using the pytest command:

   pytest test_twttr.py
   

4. The tests will be executed, and the results will be displayed in the terminal.

Program Code

twttr.py

def main():
    text_to_shorten = input("Input: ")
    print(f"Output: {shorten_text(text_to_shorten)}")

def shorten(word):
    return "".join([ch for ch in word if ch.lower() not in "aeiou"])

if __name__ == "__main__":
    main()

test_twttr.py

from twttr import shorten

def test_shorten():
    assert shorten("cat") == "ct"
    assert shorten("twitter") == "twttr"
    assert shorten("APPLE") == "PPL"
    assert shorten("Twitt3r") == "Twtt3r"
    assert shorten("pr,@oud!") == "pr,@d!"

How to Test

1. Run the tests as mentioned in the "How to Run the Tests" section.
2. The tests will be executed, and you will see the results in the terminal.

Sample Test Cases

1. Shorten Word with Vowels:

   • Input:

     assert shorten("cat") == "ct"
     

2. Shorten Word with Repeated Vowels:

   • Input:

     assert shorten("twitter") == "twttr"
     

3. Shorten Uppercase Word:

   • Input:

     assert shorten("APPLE") == "PPL"
     

4. Shorten Word with Numbers:

   • Input:

     assert shorten("Twitt3r") == "Twtt3r"
     

5. Shorten Word with Special Characters:

   • Input:

     assert shorten("pr,@oud!") == "pr,@d!"
     

Additional Notes

• Ensure that the twttr.py and test_twttr.py files are saved in the same directory and have the correct names.
• The shorten_text function is responsible for removing vowels from the given input string and returning the modified string. The test_shorten function in test_twttr.py tests the shorten function using various inputs and expected outputs.
• Running the tests using pytest will show whether your implementation of the shorten function is working correctly. It's important to have both the correct and incorrect versions of twttr.py to validate your tests.
