Original prompt

This section details on the original issue you should resolve

<issue_title>There are no tests</issue_title>
<issue_description>In this repository there are currently no tests.

Neither are there tests for the lua scripts, nor is there some automated "integration testing" that would run nvim in different scenarions. Also is there no automated build test of nvim.

All the tests shall be ran via workflows.

the workflows shall be generated from cue files similar to how it is done in the https://github.com/NobbZ/nixos-config repository.

Just doesn't support wildcard dependencies like Make does. Removed the
dependency syntax (cicd/*.cue cue.mod/module.cue) and consolidated the
workflow generation into a single recipe. Added informative echo messages

@copilot the check_generated is failing. Can you fix that?

...

Fixed in commit 407a99d. The issue was that just doesn't support wildcard dependency patterns like Make does (e.g., cicd/*.cue). I've removed the dependency syntax and consolidated the workflow generation into a single workflows recipe that generates both files. The CI should now pass.

- Remove outdated scripts/ reference from copilot-instructions.md
- Fix just-version parameter in workflows (use hyphen not underscore)
- Remove IMPLEMENTATION_SUMMARY.md (not needed in repo)
- Remove Python cache files (__pycache__) and add to .gitignore
- Remove redundant apps section from bin/default.nix (package is enough)
- Update run-tests.py to search parent directories for flake.nix
- Add system detection in run-tests.py to work on different platforms
- Extract CUE and Just versions to top of workflows.cue file
- Remove community cache from Nix configuration (not needed)
- Remove _freeSpace step (build won't exceed workflow size limit)
- Regenerate workflow files to reflect all CUE changes

In @.github/workflows/check-generated.yml:
- Around line 1-22: Update the Just installer step "Install Just" to use
just-version "1.39.0" (or a >=1.39.0 range) in the workflow step that uses
extractions/setup-just@v2 by changing the just-version field value from "1.36.0"
to "1.39.0" so the CI installs the newer Just release.

In @.github/workflows/pull-check.yml:
- Line 47: The workflow hardcodes Nix systems as
checks.x86_64-linux.integration-tests and checks.x86_64-linux.lua-tests; update
the CUE source (likely cicd/workflows.cue) so the generated job steps do not
embed "x86_64-linux" directly: either (preferred) add a systems matrix in the
CUE job generation so jobs are emitted for each target system (e.g., a systems
list that produces checks.<system>.integration-tests and
checks.<system>.lua-tests), or (alternative) interpolate the current system at
runtime by generating the step to run nix build .#checks.$(nix eval --impure
--raw --expr builtins.currentSystem).integration-tests (and similar for
lua-tests); ensure you remove the literal "x86_64-linux" occurrences in the CUE
templates so other architectures (aarch64-linux, darwin, etc.) are supported.

In @bin/run-tests.py:
- Around line 77-80: After finding the flake root (flake_root =
find_flake_root()) the script never changes the current working directory, so
nix commands may run from the wrong path; add a chdir to the found flake root
(os.chdir(flake_root)) immediately after the flake_root check and before
returning/continuing execution, and ensure the os module is imported at the top
of the file if not already present; keep the existing error path using
print_error("Not in a Nix flake directory...") unchanged.
- Around line 65-71: The run_command function has an unused parameter
description and a redundant returncode check; remove the unused description
parameter from the run_command signature (keep only cmd: list[str]) and simplify
the function to call subprocess.run(cmd, check=True) inside a try/except that
returns True on success and False on CalledProcessError, then update all call
sites that pass a description (e.g., places invoking run_command with two args)
to pass only the command list.

In @cicd/workflows.cue:
- Around line 13-40: The workflow step defined by _installJust pins the just
installer action to "extractions/setup-just@v2" which is outdated; update the
uses field in the _installJust githubactions.#Step from
"extractions/setup-just@v2" to "extractions/setup-just@v3" so the step uses the
latest stable action version (leave the step name and "with" block unchanged).

In @cue.mod/module.cue:
- Around line 1-10: The CUE module's language.version is outdated; update the
language.version field (symbol: language.version) from "v0.14.2" to the latest
"v0.15.3" and re-run any tooling to ensure compatibility; additionally review
the githubactions dependency entry (symbol: deps."cue.dev/x/githubactions@v0"
with v: "v0.2.0") against the CUE Central Registry and bump its v value if a
newer release is available.

In @TESTING_GUIDE.md:
- Line 214: Replace the bare URL in the line that reads "Solution: Install Nix:
https://nixos.org/download.html" with Markdown link syntax; update it to use a
descriptive link text such as "Install Nix" or "Nix download" (e.g., "Solution:
Install Nix: [Install Nix](https://nixos.org/download.html)") so the MD034
no-bare-urls lint rule is satisfied.
- Line 221: In TESTING_GUIDE.md remove or replace the outdated line that reads
"Check `IMPLEMENTATION_SUMMARY.md` for technical details" (the removed
IMPLEMENTATION_SUMMARY.md file) — either delete the line or update it to point
to a current, valid document (e.g., README.md or another implementation doc) and
ensure any link/anchor is correct and builds without broken references.

In @tests/default.nix:
- Around line 9-30: The lua-tests derivation only checks syntax with luac;
update the buildPhase to invoke the actual test runner (the busted package
included in nativeBuildInputs) so CI fails on test failures: replace or augment
the current luac loop in buildPhase with a command that runs busted (referencing
the busted binary from pkgs.luajitPackages.busted or simply `busted`) against
tests/lua, and ensure the command exits non‑zero on failure so the derivation
fails when tests fail; keep the luac syntax check if you want both validation
and test execution.

In @tests/integration/test-lsp.sh:
- Around line 23-26: The script exits early with `exit 1` which skips later
cleanup and also uses a hardcoded /tmp path; introduce a temporary log file
(e.g., LOG_FILE=$(mktemp)) instead of /tmp/nvim-lsp-test.log and set a trap at
the top like `trap 'rm -f "$TMP_FILE" "$LOG_FILE"' EXIT` (or a failure-specific
trap that cats the log before removing it) to guarantee removal of both TMP_FILE
and LOG_FILE on any exit, and replace occurrences of the hardcoded path with
"$LOG_FILE" and remove the explicit `rm -f "$TMP_FILE"`/`cat`/`exit` sequence so
cleanup always runs via the trap.
- Around line 19-26: The current pipeline uses `timeout ... | tee
/tmp/nvim-lsp-test.log` so the exit code of `tee` masks the NVIM command;
capture the real exit status of the left side and use that to decide pass/fail.
Replace the pipeline with one of: run the command redirecting stdout/stderr into
the log file and then test `$?` (e.g. `timeout 10 $NVIM ... 2>&1 >
/tmp/nvim-lsp-test.log` then check `$?`), or keep `tee` but capture the producer
status via `status=${PIPESTATUS[0]}` (bash) after `timeout 10 $NVIM ... 2>&1 |
tee /tmp/nvim-lsp-test.log` and use `$status` to decide success/failure; ensure
you still clean up `$TMP_FILE` on failure and print `/tmp/nvim-lsp-test.log`
when nonzero.
- Line 11: The TMP_FILE assignment uses the GNU-only "mktemp --suffix=.lua";
replace that with a portable mktemp invocation that uses a template containing X
characters (e.g., a template like "tmp.XXXXXX.lua") so both GNU and BSD/macOS
mktemp implementations work; update the line that sets TMP_FILE (the one calling
mktemp --suffix=.lua) to use the template form instead and ensure the created
filename ends with .lua.

In @tests/integration/test-startup.sh:
- Around line 11-17: The pipeline using NVIM --headless ... | tee
/tmp/nvim-healthcheck.log is masked by tee returning 0; change the check to
preserve Neovim's exit status by either enabling pipefail before running the
pipeline (set -o pipefail) or inspecting PIPESTATUS[0] right after the pipeline
and failing if it's non-zero; update the if/else logic around the NVIM
invocation (and continue to write output to /tmp/nvim-healthcheck.log) so the
script exits with failure when Neovim's exit code indicates an error.
🧹 Nitpick comments (5)
tests/lua/health_spec.lua (1)

13-23: Tests work correctly; consider optional assertion refinement.

The invocation tests correctly verify that the register functions don't throw errors (any error would fail the test before the assertion is reached). The current pattern is functional.

♻️ Optional: Consider more idiomatic assertion patterns

For tests that verify no errors occur, you could either:

  1. Omit the assertion entirely (busted allows this):
   it("should register programs correctly", function()
     health.register_program("test-program")
-    -- Just verify it doesn't error
-    assert.is_true(true)
   end)
  1. Or use a more descriptive assertion if you want to explicitly capture return values in the future.

Both approaches are valid; the current implementation works correctly.

tests/README.md (1)

1-57: Excellent test documentation; minor capitalization fix needed.

The documentation clearly explains the test infrastructure, how to run tests, and how to write new tests. This will be valuable for contributors.

📝 Minor fix: Capitalize "GitHub"

Line 56 should use the official platform name capitalization:

-Tests are automatically run on pull requests through GitHub Actions workflows
+Tests are automatically run on pull requests through GitHub Actions workflows

(Note: The word "github" in the path .github/workflows/ is correctly lowercase as it's a directory name.)

tests/lua/helpers_spec.lua (1)

1-16: LGTM!

The test correctly validates the git_root function's existence and return type, and follows all Lua coding guidelines (local variables, double quotes, call parentheses).

♻️ Optional: More idiomatic assertion

Line 14 could use busted's type assertions more idiomatically:

-    assert.is_true(type(result) == "string" or result == nil)
+    assert.is_true(result == nil or type(result) == "string")

Or even more explicitly:

-    assert.is_true(type(result) == "string" or result == nil)
+    if result ~= nil then
+      assert.is_string(result)
+    end
tests/default.nix (1)

33-92: Use checkPhase for test execution and add dontBuild = true.

The integration tests run in buildPhase, but Nix convention for test derivations is to:

  • Set dontBuild = true; to skip the build phase
  • Execute tests in checkPhase instead
  • Use installPhase only to write result artifacts

This makes the intent clearer and follows stdenv conventions.

♻️ Refactor to use checkPhase
       integration-tests = pkgs.stdenv.mkDerivation {
         name = "integration-tests";
         src = ./.;

44-62: Document the fallback behavior for unknown systems.

Line 61-62 silently defaults to x86_64-linux when the system can't be detected. This fallback might cause confusing errors on unsupported platforms. Consider either:

  1. Logging a warning about the fallback, or
  2. Raising an error for unsupported systems
⚠️ Proposed enhancement
     # Default to x86_64-linux if we can't detect
+    print(f"{Colors.YELLOW}Warning: Could not detect system (got {system}/{machine}), defaulting to x86_64-linux{Colors.NC}")
     return "x86_64-linux"

Or alternatively, fail explicitly:

-    # Default to x86_64-linux if we can't detect
-    return "x86_64-linux"
+    # Unsupported system
+    print_error(f"Unsupported system: {system}/{machine}")
+    sys.exit(1)

🔇 Additional comments (22)
tests/lua/lazy_spec.lua (1)

1-20: LGTM! Good starting point for test coverage.

The test correctly verifies the public API surface of the nobbz.lazy module and follows Lua coding guidelines (uses local, double quotes, and call parentheses).

.gitignore (1)

7-10: LGTM! Standard Python ignore patterns.

The Python cache file patterns are correctly configured to support the new Python test runner introduced in this PR.

tests/lua/health_spec.lua (1)

1-11: LGTM! API surface verification looks good.

The existence checks for register_program and register_lsp functions follow Lua coding guidelines and establish baseline test coverage.

flake.nix (2)

10-10: LGTM! Tests module correctly integrated.

The addition of ./tests to imports properly integrates the test infrastructure into the flake's module system.


44-44: LGTM! Workflow tooling correctly added to devShell.

Adding cue and just to the development shell properly supports the CUE-based workflow generation and justfile automation introduced in this PR.

tests/integration/test-startup.sh (1)

20-25: LGTM!

The timeout command correctly handles both hanging and failing nvim processes, and will properly propagate failures.

README.md (1)

10-54: LGTM!

The new Testing and Workflow Generation sections clearly document the test infrastructure and CI/CD workflow generation process. The commands are accurate and well-organized, with appropriate cross-references to detailed documentation.

justfile (1)

1-32: LGTM!

The justfile provides clear, well-documented targets for workflow generation, verification, and formatting. The commands correctly use CUE export/vet and align with the project's formatting requirements (alejandra for Nix, cue fmt for CUE files).

cicd/workflows.cue (2)

42-84: LGTM!

The job definitions correctly compose steps and use appropriate nix commands with --print-build-logs for CI visibility. The architecture-specific paths (.#checks.x86_64-linux.*) align with the PR's testing infrastructure.


5-7: All version constants are available with no known vulnerabilities.

Verification confirms:

  • Nix 2.32.1 exists (current latest: 2.33.0)
  • CUE v0.14.2 exists (current latest: v0.15.3)
  • Just 1.36.0 exists (current latest: 1.46.0)

No public CVEs found for any of these versions. While they are not the absolute latest releases, they remain supported and secure for CI/CD workflows.

cicd/README.md (1)

1-98: Comprehensive and accurate CI/CD documentation.

The documentation clearly explains the CUE-based workflow generation approach, with well-structured sections covering structure, generation commands, workflow overview, and practical guidance for adding new workflows. Code examples for common patterns (reusing steps, conditionals) are syntactically correct and helpful.

TESTING_GUIDE.md (1)

1-223: Well-structured testing guide with practical examples and CI/CD integration.

The guide comprehensively covers quick start, test types, local execution, CI/CD workflows, debugging, best practices, and troubleshooting. The guidance to use :checkhealth nobbz for plugin validation aligns well with project conventions, and the integration with the new test infrastructure is clearly explained.

.github/copilot-instructions.md (5)

30-30: Dev shell tools and workflow generation guidance properly documented.

The addition of cue and just to the dev shell tools list, along with the clarification that these are used for "making changes to Lua code or generating workflows," accurately reflects the new workflow generation infrastructure.

Also applies to: 32-32


59-66: Testing and workflow generation commands correctly integrated into validation steps.

New sections clearly document how to run tests via nix commands (nix run .#run-tests, nix build .#checks.x86_64-linux.lua-tests, etc.) and workflow generation via justfile targets (just workflows, just check, just fmt), providing developers with clear paths to validate changes.


125-138: New project structure sections accurately document tests/ and cicd/ directories.

The documentation correctly describes the new testing infrastructure (Lua unit tests, integration tests) and CUE-based workflow generation, with appropriate cross-references to dedicated documentation files (tests/README.md, cicd/README.md).


189-199: Validation steps comprehensively updated to include testing and workflow verification.

The expanded validation checklist now includes running tests, checking health with :checkhealth nobbz, verifying workflows if CUE files were modified, and explicitly notes that workflows are generated from CUE definitions rather than edited directly. This aligns with best practices and prevents common mistakes.


183-199: Copilot instructions file successfully updated to reflect major refactor.

Per coding guidelines, .github/copilot-instructions.md has been comprehensively updated after this major refactor to remain accurate and reflect the new testing infrastructure, CI/CD workflow generation, and project structure changes. The file now serves as an up-to-date onboarding reference.

bin/default.nix (1)

10-10: Consider adding run-tests to checks for CI validation.

The run-tests package follows the same pattern as add-plugin and update-plugins (lines 8-9), which are both included in the checks section (lines 14-15). However, run-tests is not added to checks.

Is this intentional? If run-tests should be validated in CI like the other tools, consider adding it to the checks section:

📋 Suggested addition to checks section
    checks = {
      add-plugin = self'.packages.add-plugin;
      update-plugins = self'.packages.update-plugins;
+     run-tests = self'.packages.run-tests;
    };
tests/integration/test-lsp.sh (1)

19-19: Consider test validity: Using 'cat' as LSP server.

The test uses cmd={'cat'} which is not a real LSP server. This may not properly validate LSP functionality since 'cat' will not respond to LSP protocol messages.

Is the intent to:

  1. Test that LSP infrastructure can start (current behavior), or
  2. Test actual LSP functionality (would require a real LSP server)?

If testing actual LSP functionality is desired, consider using a minimal Lua LSP server or mock LSP implementation that can respond to basic LSP requests.

cicd/check-generated.cue (1)

1-16: LGTM! All referenced step definitions are properly defined.

The CUE workflow definition is well-structured and follows the githubactions schema correctly. All three step definitions (_cloneRepo, _installCue, _installJust) are properly defined in cicd/workflows.cue, and the "check" target is defined in the justfile at line 20. The workflow will correctly run on pull requests and execute the configured validation steps.

bin/run-tests.nix (1)

1-8: LGTM! Clean wrapper implementation.

The shell script wrapper is well-structured: exec replaces the shell process with Python (avoiding an unnecessary parent process), and "$@" correctly forwards all arguments to the Python script.

cicd/pull-check.cue (1)

1-14: LGTM! Clean CUE workflow definition.

The workflow structure is well-organized, using composition with the referenced job templates (_buildFlake, _buildChecks, _luaTests, _integrationTests). The trigger on pull_request is appropriate for a PR checker workflow.

Note: The hardcoded x86_64-linux system issue in the generated workflow YAML likely originates from the job template definitions (presumably in workflows.cue), not from this file.

⚠️ Potential issue | 🟠 Major

Hardcoded x86_64-linux breaks multi-architecture support.

Lines 47 and 61 hardcode the system architecture in the nix build commands:

  • nix build .#checks.x86_64-linux.integration-tests
  • nix build .#checks.x86_64-linux.lua-tests

This prevents the workflow from running on other architectures (aarch64-linux, darwin variants). Since this file is generated from CUE definitions, the fix should be applied to the CUE source (likely cicd/workflows.cue).

Consider these solutions:

  1. Preferred: Use a matrix strategy in CUE to generate jobs for multiple systems
  2. Alternative: Use nix build .#checks.$(nix eval --impure --raw --expr builtins.currentSystem).integration-tests to detect the system dynamically

Would you like me to search for the CUE source that generates these hardcoded system references?

#!/bin/bash
# Find where x86_64-linux is hardcoded in CUE definitions
rg -n "x86_64-linux" cicd/

checks.x86_64-linux.lua-tests; update the CUE source (likely cicd/workflows.cue)
so the generated job steps do not embed "x86_64-linux" directly: either
(preferred) add a systems matrix in the CUE job generation so jobs are emitted
for each target system (e.g., a systems list that produces
checks.<system>.integration-tests and checks.<system>.lua-tests), or
(alternative) interpolate the current system at runtime by generating the step
to run nix build .#checks.$(nix eval --impure --raw --expr
builtins.currentSystem).integration-tests (and similar for lua-tests); ensure
you remove the literal "x86_64-linux" occurrences in the CUE templates so other
architectures (aarch64-linux, darwin, etc.) are supported.

⚠️ Potential issue | 🟡 Minor

Unused parameter and redundant return check.

Two issues in run_command:

  1. The description parameter (line 65) is never used—consider removing it or using it in error messages for better diagnostics.
  2. Line 69's result.returncode == 0 check is redundant: when subprocess.run is called with check=True, it raises CalledProcessError on non-zero exit, so reaching line 69 means the return code is already 0.

Based on static analysis hints.

Missing chdir to flake root after finding it.

The script finds the flake root directory but doesn't change to it. This means nix commands will be executed from the current working directory, which may not be the flake root. If invoked from a subdirectory, commands like nix build .#neovim may fail.

⚠️ Potential issue | 🟠 Major

The lua-tests check only validates syntax, not running actual tests.

The derivation includes busted in nativeBuildInputs but only uses luac -p for syntax validation. While the comment on line 17 indicates this is intentional ("For now, just verify..."), this means the lua-tests job in CI won't catch test failures—only syntax errors.

Consider running the actual test suite with busted. Would you like me to provide a diff that executes the tests properly?

In @tests/default.nix around lines 9 - 30, The lua-tests derivation only checks
syntax with luac; update the buildPhase to invoke the actual test runner (the
busted package included in nativeBuildInputs) so CI fails on test failures:
replace or augment the current luac loop in buildPhase with a command that runs
busted (referencing the busted binary from pkgs.luajitPackages.busted or simply
`busted`) against tests/lua, and ensure the command exits non‑zero on failure so
the derivation fails when tests fail; keep the luac syntax check if you want
both validation and test execution.

⚠️ Potential issue | 🔴 Critical

Critical: mktemp --suffix is not portable.

The --suffix flag is GNU-specific and will fail on macOS and BSD systems where mktemp has different syntax.

🔧 Portable mktemp solution
-TMP_FILE=$(mktemp --suffix=.lua)
+TMP_FILE=$(mktemp).lua
+mv "$(mktemp)" "$TMP_FILE" 2>/dev/null || TMP_FILE=$(mktemp -t tmp.XXXXXX).lua

Or use a simpler portable approach:

-TMP_FILE=$(mktemp --suffix=.lua)
+TMP_FILE=$(mktemp)
+mv "$TMP_FILE" "$TMP_FILE.lua"
+TMP_FILE="$TMP_FILE.lua"

In @tests/integration/test-lsp.sh at line 11, The TMP_FILE assignment uses the
GNU-only "mktemp --suffix=.lua"; replace that with a portable mktemp invocation
that uses a template containing X characters (e.g., a template like
"tmp.XXXXXX.lua") so both GNU and BSD/macOS mktemp implementations work; update
the line that sets TMP_FILE (the one calling mktemp --suffix=.lua) to use the
template form instead and ensure the created filename ends with .lua.

⚠️ Potential issue | 🔴 Critical

Critical: Pipe to tee masks exit code, preventing failure detection.

The command structure timeout ... | tee ... will always succeed because the exit code of tee is used, not the exit code of the nvim command. This means test failures won't be detected.

Resource leak: Cleanup skipped on failure.

When exit 1 is called on line 25, the cleanup on line 28 never executes. Additionally, the hardcoded /tmp/nvim-lsp-test.log path should use a temporary file instead.

🧹 Use trap for guaranteed cleanup
 NVIM=${1:-nvim}
 
+# Create temp files
+TMP_FILE=$(mktemp)
+LOG_FILE=$(mktemp)
+
+# Ensure cleanup on exit
+trap 'rm -f "$TMP_FILE" "$LOG_FILE"' EXIT

In @tests/integration/test-lsp.sh around lines 23 - 26, The script exits early
with `exit 1` which skips later cleanup and also uses a hardcoded /tmp path;
introduce a temporary log file (e.g., LOG_FILE=$(mktemp)) instead of
/tmp/nvim-lsp-test.log and set a trap at the top like `trap 'rm -f "$TMP_FILE"
"$LOG_FILE"' EXIT` (or a failure-specific trap that cats the log before removing
it) to guarantee removal of both TMP_FILE and LOG_FILE on any exit, and replace
occurrences of the hardcoded path with "$LOG_FILE" and remove the explicit `rm
-f "$TMP_FILE"`/`cat`/`exit` sequence so cleanup always runs via the trap.

⚠️ Potential issue | 🔴 Critical

Critical: Pipeline with tee masks nvim exit code.

The tee command always returns 0, so the if condition will always succeed regardless of whether nvim failed. This means the health check will never detect failures.
