Run Puzzle Tests

Run jigsawR test suite + interpret results.

Use When

• Post any R src edit
• Post new puzzle type|feature
• Pre-commit → verify nothing broke
• Debug specific fail

In

• Required: Scope (full|filtered|single)
• Optional: Filter pattern ("snic", "rectangular")
• Optional: Test file path (single mode)

Do

Step 1: Choose Scope

Scope	Use when	Duration
Full	Before commits, after major changes	~2-5 min
Filtered	Working on one puzzle type	~30s
Single	Debugging a specific test file	~10s

→ Scope chosen by workflow: full pre-commit, filtered for type work, single for debug.

If err: unsure → default full. Slower but catches cross-type regressions.

Step 2: Create+Exec Test Script

Full:

Create /tmp/run_tests.R:

devtools::test()

R_EXE="/mnt/c/Program Files/R/R-4.5.0/bin/Rscript.exe"
cd /mnt/d/dev/p/jigsawR && "$R_EXE" -e "devtools::test()"

Filtered:

"$R_EXE" -e "devtools::test(filter = 'snic')"

Single:

"$R_EXE" -e "testthat::test_file('tests/testthat/test-snic-puzzles.R')"

→ Test out w/ pass/fail/skip.

If err:

• NEVER --vanilla; renv needs .Rprofile
• renv errs → renv::restore() first
• Complex cmds fail Exit 5 → write script file

Step 3: Interpret Results

Summary line:

[ FAIL 0 | WARN 0 | SKIP 7 | PASS 2042 ]

• PASS: Succeeded
• FAIL: Need investigation
• SKIP: Skipped (missing optional pkg like snic)
• WARN: Warns (review, not blocking)

→ Summary parsed → PASS, FAIL, SKIP, WARN counts. FAIL=0 = clean.

If err: no summary → runner crashed pre-complete. Check R errs above. Output truncated → redirect: "$R_EXE" -e "devtools::test()" > test_results.txt 2>&1.

Step 4: Investigate Fails

If fail:

1. Read msg → file, line, expected vs actual
2. New fail or pre-existing?
3. Assertion → read test + tested fn
4. Error → check fn signature changed?

# Run just the failing test with verbose output
"$R_EXE" -e "testthat::test_file('tests/testthat/test-failing.R', reporter = 'summary')"

→ Root cause id'd. Real regression (fix code) or env issue (dep, path).

If err: msg unclear → add browser()|print() + re-run via testthat::test_file() for interactive debug.

Step 5: Verify Skip Reasons

Skips normal when optional deps missing:

• snic → skip_if_not_installed("snic")
• OS-specific → skip_on_os()
• CRAN-only → skip_on_cran()

Confirm legitimate, not masking real fails.

→ All skips accounted by legit reasons. None mask actual fails.

If err: skip suspicious → temp remove skip_if_*() + run → see if pass or hidden fail.

Check

• All pass (FAIL=0)
• No unexpected warns
• Skip matches expected (only optional dep skips)
• Test count not decreased (no accidentally removed)

Traps

• --vanilla: Breaks renv. Never w/ jigsawR.
• Complex -e strings: Shell escape → Exit 5. Use script files.
• Stale pkg state: Run devtools::load_all()|document() before test if NAMESPACE changed.
• Missing test deps: Some need Suggests pkgs. Check DESCRIPTION.
• Parallel issues: Tests interfere → run sequential w/ testthat::test_file().

→

• generate-puzzle — gen puzzles → verify behavior matches tests
• add-puzzle-type — new types need comprehensive suites
• write-testthat-tests — general R test patterns
• validate-piles-notation — test PILES parse standalone
