[Tutor] importing modules from a src directory to test in a module in a testing directory

[Alex Kleider]

How to import a module from a src directory for testing
in a test program found in a sister test directory?

Using Debian Linux...
Here's my project's directory structure:

TopLevel
├── __init__.py
├── src
│   ├── __init__.py
│   └── myprogram.py
└── tests
    ├── __init__.py
    └── test_myprogram.py

... and content of relevant files:

$ cat src/myprogram.py
#!/usr/bin/env python3
# File: utils/myprogram.py
def print_greeting():
    greeting = "Helo world"
    print(greeting)
    return greeting
if __name__ == "__main__":
    print_greeting()

$ cat tests/test_myprogram.py
#!/usr/bin/env python3
# File: tests/test_myprogram.py
from .. src import myprogram

... then attempting to run the test:

$ ./tests/test_myprogram.py 
Traceback (most recent call last):
  File "/home/alex/Projects/TopLevel/./tests/test_myprogram.py", line 5, in <module>
    from ..src import myprogram
ImportError: attempted relative import with no known parent package

Any help as to how this can be fixed would be most welcome!
Cheers,
