tsafe-cli 1.0.22

tsafe CLI — local secret and credential manager (replaces .env files)
Documentation
//! Integration tests for `tsafe ssm-push` (ADR-030 write contract).
//!
//! Tests focus on unit-testable SSM path reconstruction logic (pure functions)
//! and the dry-run / non-interactive abort contract for the CLI surface.
//!
//! All tests run only when the `cloud-pull-aws` feature is active.

    // ── Test: dry-run requires no credentials ─────────────────────────────────
    // With --dry-run on an empty vault (no secrets match the path prefix),
    // the command should succeed and report nothing to push.
    // NOTE: even dry-run does a remote fetch (to compute diff), so we need
    // a valid (if empty) response. Since we can't easily override the SSM
    // endpoint in integration tests without a seam env var, we test the
    // non-interactive abort contract, which aborts before any network call.

        // Without valid AWS credentials the command will fail at the remote
        // fetch stage — but the --yes check happens after the diff computation
        // (which requires network). For the non-interactive abort test we need
        // to ensure --yes is checked. We use a path where no local keys match
        // so the command exits cleanly even without a live endpoint.
        // An empty vault under /other/ with no credentials → region missing error.
        // Instead, check that without --yes and with real local keys but no
        // real AWS config, we still see the non-TTY abort message.
        // We pass invalid credentials to make the network fail, but the abort
        // check must happen BEFORE writes.
        //
        // The simplest reliable test: dry-run should never need --yes.
        // Verify that dry-run exits 0 even when no credentials (will fail at
        // remote fetch). So we skip the dry-run test here and only test
        // that the command requires --yes when stdin is non-interactive.
        //
        // We test by pointing at a local mock: cmd_ssm_push reads region from
        // env. With no region set, the command fails before the --yes check.
        // So we set a region but a bad endpoint and expect either:
        //   (a) transport error before the --yes check (not ideal), or
        //   (b) the non-TTY error from --yes.
        //
        // The most robust test here is the unit tests in cmd_ssm_push.rs.
        // For integration, we test the --dry-run path with an empty vault:
        // even with no remote access, if the vault has no matching keys the
        // command exits 0 immediately.
        let dir2 = tempdir().unwrap();
        init_vault(dir2.path());
        // No secrets in the vault matching /other/ → exits with "nothing to push".
        // But remote fetch still happens. Use a guaranteed-to-fail endpoint
        // so we see a network error. Then confirm the error message is about
        // network, not about missing --yes (confirming no --yes check needed
        // before the diff is computed).
        //
        // Since we can't easily inject a mock endpoint for SSM here (no seam env),

        // happens after the local key list is built, which is BEFORE the remote fetch

        // for the collision error rather than a transport error.
