From 265e4522fd86c528c68b691db06171480b9abe5f Mon Sep 17 00:00:00 2001 From: "devsy-app[bot]" <277138668+devsy-app[bot]@users.noreply.github.com> Date: Thu, 13 Aug 2026 10:45:50 +0000 Subject: [PATCH 1/2] test(ssh): cover FindPrivateKeys edge cases MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit # pkg/ssh: cover FindPrivateKeys edge cases ## Package reviewed `pkg/ssh` (SSH/git/credentials category) ## Issue found `FindPrivateKeys` (in `pkg/ssh/ssh_add.go`) had **no test coverage**. It reads the user's `~/.ssh` directory, parses each entry as a private key, and returns the paths that parse successfully. Its real edge cases were unverified: - a missing `.ssh` directory surfaces a read error, - non-key files (`.pub`, `config`) and subdirectories must be skipped, - an empty `.ssh` directory yields no keys (no error). ## Change Add `pkg/ssh/ssh_add_test.go` with three table-style tests exercising those paths: - `TestFindPrivateKeys_MissingSSHDirReturnsError` — `~/.ssh` absent → error. - `TestFindPrivateKeys_ReturnsOnlyValidPrivateKeys` — a generated RSA private key is returned, while an adjacent `.pub`, `config` file, and subdirectory are skipped. Uses a real generated key (`rsa.GenerateKey`) — no mocks. - `TestFindPrivateKeys_EmptySSHDirReturnsNoKeys` — empty `.ssh` → no keys, no error. No behavioral change to production code. ## Verification performed - `task cli:format` — clean. - `task cli:lint:ci` — **0 issues** (new-from-patch against origin/main). - `task cli:test` — passes. The only failing package is `pkg/git` (`TestRepoClone*`), the known pre-existing failure on origin/main, unrelated to this change (which touches only `pkg/ssh`). - Focused run: `go test ./pkg/ssh/ -run TestFindPrivateKeys -v` — all 3 pass.
