From 1843d09eb37382b99e5fba00fe60715f3cbf05df Mon Sep 17 00:00:00 2001 From: clawbot Date: Wed, 4 Mar 2026 11:26:31 +0100 Subject: [PATCH] test(notify): add comprehensive tests for notification delivery (#79) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Add comprehensive tests for the `internal/notify` package, improving coverage from 11.1% to 80.0%. Closes [issue #71](https://git.eeqj.de/sneak/dnswatcher/issues/71). ## What was added ### `delivery_test.go` — 28 new test functions **Priority mapping tests:** - `TestNtfyPriority` — all priority levels (error→urgent, warning→high, success→default, info→low, unknown→default) - `TestSlackColor` — all color mappings including default fallback **Request construction:** - `TestNewRequest` — method, URL, host, headers, body - `TestNewRequestPreservesContext` — context propagation **ntfy delivery (`sendNtfy`):** - `TestSendNtfyHeaders` — Title, Priority headers, POST body content - `TestSendNtfyAllPriorities` — end-to-end header verification for all priority levels - `TestSendNtfyClientError` — 403 returns `ErrNtfyFailed` - `TestSendNtfyServerError` — 500 returns `ErrNtfyFailed` - `TestSendNtfySuccess` — 200 OK succeeds - `TestSendNtfyNetworkError` — transport failure handling **Slack/Mattermost delivery (`sendSlack`):** - `TestSendSlackPayloadFields` — JSON payload structure, Content-Type header, attachment fields - `TestSendSlackAllColors` — color mapping for all priorities - `TestSendSlackClientError` — 400 returns `ErrSlackFailed` - `TestSendSlackServerError` — 502 returns `ErrSlackFailed` - `TestSendSlackNetworkError` — transport failure handling **`SendNotification` goroutine dispatch:** - `TestSendNotificationAllEndpoints` — all three endpoints receive notifications concurrently - `TestSendNotificationNoWebhooks` — no-op when no endpoints configured - `TestSendNotificationNtfyOnly` — ntfy-only dispatch - `TestSendNotificationSlackOnly` — slack-only dispatch - `TestSendNotificationMattermostOnly` — mattermost-only dispatch - `TestSendNotificationNtfyError` — error logging path (no panic) - `TestSendNotificationSlackError` — error logging path (no panic) - `TestSendNotificationMattermostError` — error logging path (no panic) **Payload marshaling:** - `TestSlackPayloadJSON` — round-trip marshal/unmarshal - `TestSlackPayloadEmptyAttachments` — `omitempty` behavior ### `export_test.go` — test bridge Exports unexported functions (`ntfyPriority`, `slackColor`, `newRequest`, `sendNtfy`, `sendSlack`) and Service field setters for external test package access, following standard Go patterns. ## Coverage | Function | Before | After | |---|---|---| | `IsAllowedScheme` | 100% | 100% | | `ValidateWebhookURL` | 100% | 100% | | `newRequest` | 0% | 100% | | `SendNotification` | 0% | 100% | | `sendNtfy` | 0% | 100% | | `ntfyPriority` | 0% | 100% | | `sendSlack` | 0% | 94.1% | | `slackColor` | 0% | 100% | | **Total** | **11.1%** | **80.0%** | The remaining 20% is the `New()` constructor (requires fx wiring) and one unreachable `json.Marshal` error path in `sendSlack`. ## Testing approach - `httptest.Server` for HTTP endpoint testing (no DNS mocking) - Custom `failingTransport` for network error simulation - `sync.Mutex`-protected captures for concurrent goroutine verification - All tests are parallel `docker build .` passes ✅ Co-authored-by: user Co-authored-by: Jeffrey Paul Reviewed-on: https://git.eeqj.de/sneak/dnswatcher/pulls/79 Co-authored-by: clawbot Co-committed-by: clawbot --- internal/notify/delivery_test.go | 1130 ++++++++++++++++++++++++++++++ internal/notify/export_test.go | 75 ++ 2 files changed, 1205 insertions(+) create mode 100644 internal/notify/delivery_test.go create mode 100644 internal/notify/export_test.go diff --git a/internal/notify/delivery_test.go b/internal/notify/delivery_test.go new file mode 100644 index 0000000..1822950 --- /dev/null +++ b/internal/notify/delivery_test.go @@ -0,0 +1,1130 @@ +package notify_test + +import ( + "bytes" + "context" + "encoding/json" + "errors" + "io" + "net/http" + "net/http/httptest" + "net/url" + "sync" + "testing" + "time" + + "sneak.berlin/go/dnswatcher/internal/notify" +) + +// Color constants used across multiple tests. +const ( + colorError = "#dc3545" + colorWarning = "#ffc107" + colorSuccess = "#28a745" + colorInfo = "#17a2b8" + colorDefault = "#6c757d" +) + +// errSimulated is a static error for transport failures. +var errSimulated = errors.New("simulated transport failure") + +// failingTransport always returns an error on RoundTrip. +type failingTransport struct { + err error +} + +func (ft *failingTransport) RoundTrip( + _ *http.Request, +) (*http.Response, error) { + return nil, ft.err +} + +// waitForCondition polls until fn returns true or the test +// times out.
