Adding Testing Libraries to your virtual environment

• We have add the basic code to add two numbers Refer Here

• To test this code we would be using the following block with different

if __name__ == "__main__":
    print(add(5,6))
    print(add(-1,1))

• The better way of testing your code is by performing unit tests.
• Install pytest pip install pytest
  
• The installations of packages which we have done in our project have to be explicitly defined.
  
• If the code is shared with other developer, the other developer has to create a venv and the activate the venv and execute the command pip install -r requirements.txt
  
• Now lets write a simple test module test_sample with test case test_add_numbers. Lets see the result
  
• If we have some error the output will be as shown below
  
• Lets configure pytest in vscode
  
  
  
  
• Now lets debug
  
• Refer Here for the changes done
  

Exercise: Write a function and test cases in a new module

• This module can be called as picnic and test module will be test_picnic
• Create a function called as food_items which takes any number of arguments

Function Call                               Sample Output
food_items('salad')                     => You are bringing salad
food_items('salad', 'chips')            => You are bringing salad and chips
food_items('salad', 'chips', 'cake')    => You are bringing salad, chips and cupcakes
