e4代码在代码中是如何测试的?

def test_function(x):
  """
  This function tests the functionality of the main function.

  Args:
    x: The input value for the function.

  Returns:
    None
  """

  # This is just a placeholder for the actual function implementation.
  return x + 1


if __name__ == "__main__":
  test_function(5)

Explanation:

1. test_function function:

   • This function takes a single argument x.
   • It defines a function named test_function that takes a single argument x.
   • The function returns x + 1.

2. if __name__ == "__main__": block:

   • This block of code checks if the current module is being run directly or imported.
   • If the module is being directly run, it calls the test_function with the argument 5.

3. test_function(5):

   • This line calls the test_function function with the argument 5.
   • The test_function calculates 5 + 1 and returns the result, which is 6.

How it's tested:

When you run the script, it will execute the test_function with the argument 5. The function will calculate 5 + 1 and return 6.

Purpose:

The test_function is a unit test that ensures that the main function is working correctly. It checks if the function is correctly calculating the input value plus 1.
