Subject: feat: pearl — manage Linear issues from org-mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pearl fetches Linear issues into an org file and syncs edits back. It covers list / custom views / saved queries, per-issue and bulk rendering with comments inline, conflict-aware sync of descriptions, titles, and comments, field commands for priority / state / assignee / labels, and a transient dispatch menu. The render folds to a scannable outline and nests issues under a sortable parent.

Based on and inspired by Gael Blanchemain's linear-emacs.

+#+TITLE: Testing pearl
+#+OPTIONS: toc:2
+
+* Overview
+
+pearl uses [[https://github.com/jorgenschaefer/emacs-lisp-mode][ERT]] for tests, [[https://emacs-eask.github.io/][Eask]] to manage the test sandbox and dependencies, and [[https://github.com/undercover-el/undercover.el][undercover]] for coverage reports. A root =Makefile= drives everything and delegates test targets to =tests/Makefile=.
+
+* Prerequisites
+
+- Emacs 27.1+
+- [[https://emacs-eask.github.io/Getting-Started/Install-Eask/][Eask]] on =PATH= (=npm install -g @emacs-eask/cli=, or the standalone installer)
+
+* First-time setup
+
+#+begin_src shell
+make setup
+#+end_src
+
+Installs runtime deps (=request=, =dash=, =s=) and development deps (=elisp-lint=, =package-lint=, =undercover=) into a project-local =.eask/= sandbox.
+
+** Note on Eask's global package store
+
+Eask keeps a global package store at =~/.eask/<emacs-version>/elpa/=. When a dependency already sits there at the version the project wants, =eask install-deps= skips installing it into the project sandbox — but =eask emacs= (which runs the tests) only activates the project sandbox, so the dependency ends up "installed" yet unloadable. =make setup= guards against this: after =eask install-deps= it verifies each runtime dep is present in the sandbox and installs any that were skipped. The guard is a no-op where the global store is empty (fresh clones, CI).
+
+* Running tests
+
+#+begin_src shell
+make test                      # all tests, excluding :slow
+make test-all                  # all tests, including :slow
+make test-unit                 # unit tests only
+make test-integration          # integration tests only
+make test-file FILE=mapping    # one file (fuzzy match on name)
+make test-one TEST=priority    # one test (fuzzy match on name)
+make test-name TEST='pattern'  # tests matching an ERT name pattern
+#+end_src
+
+* Coverage
+
+#+begin_src shell
+make coverage
+#+end_src
+
+Cleans =.elc= files (so undercover can instrument the source), runs every test file in its own Emacs process with =pearl.el= instrumented, and merges per-file results into =.coverage/simplecov.json=. Under CI (=CI=true=) it emits =.coverage/coveralls.json= instead for upload.
+
+* Other targets
+
+#+begin_src shell
+make validate    # parens-balance check (no deps needed)
+make compile     # byte-compile pearl.el (warnings are errors)
+make lint        # elisp-lint over pearl.el
+make count       # count tests per file
+make list        # list all test names
+make clean       # remove .elc, logs, and .coverage
+make help        # full target list
+#+end_src
+
+=make compile= (warnings as errors), =make lint=, and =eask lint checkdoc= are all clean; keep them that way as part of normal maintenance.
+
+* Writing tests
+
+- One test file per source function/area: =tests/test-pearl-<area>.el=.
+- Start each file with =(require 'test-bootstrap (expand-file-name "test-bootstrap.el"))= — it loads the deps and the package source.
+- Name tests =test-pearl-<function>-<scenario>-<expected>=.
+- Cover Normal, Boundary, and Error cases.
+- Tag slow tests with =:tags '(:slow)= so the default =make test= skips them.
+- Integration files are named =tests/test-integration-*.el=.
