That’s a detailed set of pytest results! It looks like you had 10 tests pass and 3 tests fail.
Here is a breakdown of the overall results and the specific issues causing the three failures.
🚀 Test Session Summary
The test session collected 13 items.
- PASSED: 10 tests
- FAILED: 3 tests
- Total Time: 0.39 seconds
🛑 Analysis of Failed Tests
1.
tests/test_main.py::test_main_full_cli_runThis test failed with a
SystemExit: 2error during argument parsing, indicating an issue with how the script handled the command-line arguments.
- Root Cause: The
argparselibrary reported unrecognized arguments.main.py: error: unrecognized arguments: --root /Users/boomer/work/myPython/wp-skeleton-checker/Skeletons --skeleton wp-standard- The Fix: Compare the arguments you are passing in the test (
--rootand--skeleton) with the arguments defined in theusage:section (which shows the accepted arguments):usage: main.py [-h] [--tr TEMPLATE_ROOT] [--p PLATFORM] [--pt PLATFORM_TYPE] [--pts PLATFORM_TYPE_SKELETON] [...]It appears the correct arguments are:
- You used
--root, but the script expects--tr(or--template_root).- You used
--skeleton, but the script expects--pts(or--platform_type_skeleton).2.
tests/test_project.py::test_get_project_invalid_cli_argument_drops_to_promptThis test failed with an
AssertionErrorbecause the returned project path did not match the expected path.
- Test Intent: The test checks that when an invalid path (
/invalid/cli/path) is passed via CLI, the function correctly rejects it and instead returns the path provided via the interactive prompt (valid_interactive_path).- Error Detail:
AssertionError: assert '/Users/boome...eractive_path' == 'valid_interactive_path' E - valid_interactive_path E + /Users/boomer/work/myPython/wp-skeleton-checker/valid_interactive_path- Root Cause: The test expected the raw interactive input string (
valid_interactive_path), but the function returned the absolute path (/Users/boomer/.../valid_interactive_path).- The Fix: The
get_projectfunction is likely automatically prepending the script’s root directory to the user’s input, which is a common and usually correct behavior for handling relative paths. You need to update the assertion in your test to expect the absolute path that the function returns:
- Change:
assert result == "valid_interactive_path"- To something like:
assert result.endswith("valid_interactive_path")or construct the expected absolute path using the current root directory.3.
tests/test_project.py::test_get_project_valid_interactive_inputThis test failed for the exact same reason as the previous one, where the test assertion expected the raw input string, but the function returned the absolute path.
- Error Detail:
AssertionError: assert '/Users/boome..._input_folder' == 'user_input_folder' E - user_input_folder E + /Users/boomer/work/myPython/wp-skeleton-checker/user_input_folder- The Fix: As above, update the assertion in this test to correctly account for the function returning an absolute path, not just the raw user input.
🛠️ Next Steps
You should focus on two main areas to resolve these failures:
- Correct CLI Arguments: In
tests/test_main.py, replace the CLI arguments incli_argsto match the accepted parameters (--trand--pts).- Update Assertions: In
tests/test_project.py, modify the assertions in both failed tests to expect the absolute path that theget_projectfunction is returning.Would you like me to help you draft the corrected assertion lines for
tests/test_project.py?

Should I be looking at what changed in : skeleton_app.skeleton_project import get_project ?
Yes, based on the failed tests from your previous session, you are seeing an issue caused by a discrepancy between what the
get_projectfunction returns and what your tests assert.The tests are expecting raw user input (
"valid_interactive_path"), but the function appears to be returning an absolute path (/Users/boomer/.../valid_interactive_path).You need to update the assertions in your two failing tests (
test_get_project_invalid_cli_argument_drops_to_promptandtest_get_project_valid_interactive_input) to reflect that the function is returning an absolute path, which is generally better practice in file system code.Here are the corrected versions of the two failing tests for
tests/test_project.py:
🛠️ Corrected Tests (

result.endswith(...), you are correctly testing the functionality ofget_projectwithout relying on whether it returns a relative or absolute path, only that it contains the user’s input.Do you have access to the source code for
skeleton_app.skeleton_project.get_projectand can you confirm that it usesos.path.abspath()or similar logic on the path, which would confirm this fix?
I'm on branch feature/ignore, how can I diff ./skeleton_app/skeleton_project.py to origin main?
That’s a common and useful Git operation! Since you are on the
feature/ignorebranch and want to see the changes in a specific file relative to theorigin/mainbranch, you can use thegit diffcommand.Here is the exact command you need:
Bash
git diff origin/main ./skeleton_app/skeleton_project.py
🔎 Command Breakdown
Let’s break down what each part of the command does:
git diff: This is the core command that shows the differences between two points in Git history.origin/main: This is the first endpoint of the comparison. It refers to the remote tracking branch for your main branch. This is crucial because it ensures you are comparing against the most up-to-date version of the mainline code from your remote repository../skeleton_app/skeleton_project.py: This is the pathspec (the file) you want to compare. By specifying the file, Git only shows you the differences for this file, ignoring changes in all other files between the two branches.Output Interpretation
The output will be in the standard Git diff format, which looks like this:
diff --git a/skeleton_app/skeleton_project.py b/skeleton_app/skeleton_project.py index 92b1531..a4c13e4 100644 --- a/skeleton_app/skeleton_project.py +++ b/skeleton_app/skeleton_project.py @@ -10,7 +10,8 @@ def get_project(args_project, debug=0): # ... - if os.path.isdir(args_project): + # Use os.path.abspath to normalize the path for comparison + if os.path.isdir(os.path.abspath(args_project)): print(f" ✅ 📂 - Project path found: {args_project}") return args_project
- Lines starting with

That’s a very insightful observation! You are absolutely right—the change you highlighted in
skeleton_app/skeleton_project.pyis the direct cause of theAssertionErrorfailures in your tests.Yes,
return os.path.abspath(user_input_str)is the issue that caused your tests to fail, but it’s likely a correct fix for your application’s code.Here’s the breakdown and the fix for your tests:
🛑 The Root Cause: Absolute Path
1. The Code Change (Correct App Logic)
In the file diff you provided, the line was changed from:
Python
- return user_input_str + return os.path.abspath(user_input_str)By adding
os.path.abspath(), your function is now robustly handling paths, converting any relative path (like"valid_interactive_path") into a full, absolute path (like/Users/boomer/work/myPython/wp-skeleton-checker/valid_interactive_path).2. The Test Failure (Incorrect Assertion)
Your tests were written to expect the raw input string:
Python
# test_get_project_valid_interactive_input was expecting: assert result == "user_input_folder"But the function now returns:
Python
# The function actually returns: '/Users/boomer/work/myPython/wp-skeleton-checker/user_input_folder'Since the expected value and the actual returned value are different, the assertion fails.
✅ Solution: Update the Tests
You need to update your two failing tests in
tests/test_project.pyto expect the absolute path.1.
test_get_project_invalid_cli_argument_drops_to_prompt
Old Assertion New Assertion assert result == "valid_interactive_path"assert result.endswith(os.path.join("valid_interactive_path"))Export to Sheets
2.
test_get_project_valid_interactive_input
Old Assertion New Assertion assert result == expected_pathassert result.endswith(os.path.join(expected_path))Export to Sheets
Why
endswith()?Using
result.endswith(os.path.join(expected_path))is the best approach because it confirms the path contains the correct input without tying the test to a specific user’s home directory (/Users/boomer/...), making the test portable.
🧐 Git Diff Mystery Solved
Regarding your
git diffshowing nothing, this confirms your suspicion: the change was already merged intoorigin/main.When you run:
Bash
git diff origin/main ./skeleton_app/skeleton_project.pyGit compares your current file (
feature/ignore) with the file onorigin/main. If the two files are identical, the diff shows nothing.Since you are running into test failures on your local branch, and the core change causing the failure (
os.path.abspath) is visible in the diff you provided (which must be a change you introduced or pulled in), the fix is definitely in updating your tests to match the new behavior of the application code.Would you like to review the third failed test,
tests/test_main.py::test_main_full_cli_run, to address the CLI argument issue as well?
The asset result tags like "valid_interactive_path" - where did that come from? Is that a pytest standard flag?
That’s a great question! Those strings like
"valid_interactive_path"and"user_input_folder"are not standard pytest flags or built-in test results.They are custom strings defined and used within your test file (
tests/test_project.py) to simulate user input and to serve as the expected value for your test assertions.Here is a breakdown of where they came from and their role in the test:
🎭 The Role of Custom Strings in Pytest
1. Simulating User Input (
monkeypatch)In your test functions, you use the
monkeypatchfixture to temporarily replace built-in functions, specifically theinput()function that waits for user interaction.In the test
test_get_project_invalid_cli_argument_drops_to_prompt, this code:Python
# 2. Mock input: Simulate user entering a valid path on the first prompt mock_input_values = iter(["valid_interactive_path"]) monkeypatch.setattr('builtins.input', lambda _: next(mock_input_values))
"valid_interactive_path"is the string you chose to mock or simulate what a user would type into the console when prompted by your application’sget_projectfunction.- When your code calls
input(), it receives the string"valid_interactive_path"instead of waiting for a real person to type it.2. Defining the Expected Result (
Assertion)After you run the function (
get_project), you need to verify it worked correctly.Your original, failing assertion was:
Python
# ASSERT: # The result should be the interactive path, not the invalid CLI path. assert result == "valid_interactive_path"
- Here,
"valid_interactive_path"is the expected value—the test writer’s guess as to what the function should return.- The test failed because your application’s code changed to return the absolute path (
/Users/boomer/.../valid_interactive_path), but the test was still expecting the mock input string itself.In summary:
String Source/Role Pytest Standard? "valid_interactive_path"Defined by you in the test file. No. It’s a test variable. PASSED/FAILED/SystemExitDefined by pytest. Yes. These are standard test outcomes. Export to Sheets
So pytest, imports the actual method get_project code, then replaces the results of the input line.
i.e. user_input_str = input(" Enter Project Path/Folder (e[x]it) :")
pytest sets user_input_str="valid_interactive_path" and continues processing the code ?
if user_input_str.lower() in ["x", "q", "quit", "exit"]:
print("\n 👋 Exiting. See you next time!\n")
sys.exit(0)
try:
if not user_input_str == "":
if os.path.isdir(user_input_str):
print(f" ✅ 📂 - {user_input_str}")
return os.path.abspath(user_input_str) <<== This return os.path.abspath("valid_interactive_path") ?
else:
print(f" ⚠️ Project path is invalid: {user_input_str}")
That is exactly right! You’ve perfectly described how mocking user input with
monkeypatchworks in your pytest setup.
🎯 How Pytest Mocks Your Code
You are correct on all points. Pytest, using the
monkeypatchfixture, imports and runs your actual production code, but strategically replaces certain dependencies to make the tests predictable.1. Running the Actual Method
The line
result = get_project(args_project=None, debug=0)in your test calls the actual, importedget_projectfunction. Pytest is not trying to guess what the function does; it’s running the real thing.2. Mocking
input()When the Python interpreter reaches this line in your production code:
Python
user_input_str = input(" Enter Project Path/Folder (e[x]it) :")Instead of pausing and waiting for a human to type, the
monkeypatchsetup intervenes.Your test code:
Python
mock_input_values = iter(["valid_interactive_path"]) monkeypatch.setattr('builtins.input', lambda _: next(mock_input_values))This tells the interpreter: “Any time the function
builtins.inputis called, don’t execute the normal function. Instead, run thislambdafunction, which returns the next item from the list["valid_interactive_path"].”The result is:
user_input_str=”valid_interactive_path”
3. Mocking
os.path.isdir()Since you also mocked
os.path.isdirusing themock_isdirfixture, the test bypasses a real file system check.When the code reaches:
Python
if os.path.isdir(user_input_str):The mock returns the value you pre-set (
Truein the success test).4. The Final Return Value
Because
user_input_stris set to"valid_interactive_path", andos.path.isdirreturnsTrue, the code proceeds to the return line:Python
return os.path.abspath(user_input_str)The function executes this as:
return os.path.abspath(“valid_interactive_path”)
This is why the function returns the absolute path (
/Users/boomer/.../valid_interactive_path), which caused your original assertion (assert result == "valid_interactive_path") to fail, as the test was only expecting the relative path string.You were completely correct to identify this as the issue! This technique—running the real code while mocking its external dependencies (like user input and file system checks)—is the cornerstone of effective unit testing.
Why did you add the os.path.join to assert test for result?
result.endswith("valid_interactive_path")
vs
result.endswith(os.path.join("valid_interactive_path"))
That’s a very sharp question!
I added
os.path.joinfor reasons of portability and robustness, even though in that specific context it may seem redundant.Here is why using
os.path.join()is the recommended best practice when working with file paths in Python tests:
💻 Path Portability
The core reason is that file path separators are different across operating systems:
Operating System Path Separator Windows Backslash ( \)macOS / Linux Forward slash ( /)1. The Potential Problem
If the underlying application code (
get_project) were to return a path like this:
- On Windows:
C:\Users\boomer\...\valid_interactive_pathAnd your assertion used a hardcoded forward slash:
Python
# Assuming a standard Linux/macOS separator in the string assert result.endswith("/valid_interactive_path")The assertion would fail on Windows because the path separator returned by the function (
\) wouldn’t match the separator you used in the string (/).2. The
os.path.joinSolutionThe
os.path.joinfunction automatically uses the correct path separator for the operating system where the test is running.When you write:
Python
assert result.endswith(os.path.join("valid_interactive_path"))
- On macOS/Linux:
os.path.join("valid_interactive_path")resolves to"valid_interactive_path".- On Windows:
os.path.join("valid_interactive_path")resolves to"valid_interactive_path".While it seems redundant when only joining a single component, it’s a habit that prevents future bugs. If you ever needed to assert against a longer path, for example:
Python
# Bad practice (will break on Windows if the app returns backslashes) result.endswith("my/new/folder/test_path") # Good practice (safe everywhere) result.endswith(os.path.join("my", "new", "folder", "test_path"))In your specific case:
Python
result.endswith(os.path.join("valid_interactive_path"))is functionally the same as just
result.endswith("valid_interactive_path")for a single path component on most systems. However, I included it to train the assertion on the standard practice for path comparison, making the test robust if you decide to run it in a CI/CD pipeline on a different OS (like Windows).
Would that happen of the / or \ was omitted?
result.endswith(“valid_interactive_path”)
No, the potential issue causing you to need
os.path.joinwouldn’t happen because a/or\was omitted from the string"valid_interactive_path".The problem occurs when a separator is required by the operating system, but you supply the wrong one in the assertion string, or none at all when a separator is needed to stitch path components together.
Here’s why your simple string is safe in this context, and when you would run into trouble:
✅ Why
result.endswith("valid_interactive_path")is safe hereSince
"valid_interactive_path"is a single filename or folder name with no separators in it, the assertion is comparing:
- The end of the function’s return value (e.g.,
...\valid_interactive_pathon Linux, or...\valid_interactive_pathon Windows).- The literal string (
valid_interactive_path).The separator (
/or\) is part of the path preceding the final component, but the final component itself (the one you are asserting against) does not contain a separator. Therefore, the assertion works universally.🛑 When You Need
os.path.joinYou only run into the cross-platform path issue when you need to match a path that involves multiple components and separators.
Scenario Assertion String Works Cross-Platform? Simple End Match (Your Case) "valid_interactive_path"Yes. No separators involved. Matching a Folder Structure "data/valid_interactive_path"No. Fails on Windows because it expects \.Correct Folder Structure Match os.path.join("data", "valid_interactive_path")Yes. os.path.joinprovides the correct separator for the current OS.Export to Sheets
In your specific test:
Python
# The function returns: .../valid_interactive_path assert result.endswith("valid_interactive_path")This is a simple string search that finds the component name at the end of the path, ignoring the separator that came before it. It’s perfectly robust for a single component.
I suggested
os.path.joinout of an abundance of caution and to promote the best practice for path manipulation, but in this specific test, it is not strictly necessary because the string being matched has no separators.
perfect thanks!
