Smoke testing

Active contributors: Douwe de Vries

Purpose

Smoke testing runs selected resolved requests directly from the Rust backend before a full k6 run. It is a quick check for base URL, auth, variables, headers, and target availability.

Directory layout

src/features/test/useSmokeTest.ts
src/app/components/SmokeTestCard.tsx
src-tauri/src/commands/testing/mod.rs
src-tauri/src/commands/testing/smoke.rs
src-tauri/src/importing/runtime.rs

Key abstractions

Abstraction	File	Description
SmokeTestResponse	src/lib/loadrift/types.ts, src-tauri/src/models.rs	List of smoke test results
SmokeTestResult	src/lib/loadrift/types.ts, src-tauri/src/models.rs	Status code, duration, headers, body preview, and error for one request
ResolvedRuntimeRequest	src-tauri/src/importing/mod.rs	Request after variables, base URL, and auth are resolved

Loading

smoke_test_requests in src-tauri/src/commands/testing/mod.rs rejects calls while a k6 run is busy, resolves selected requests through src-tauri/src/importing/runtime.rs, then runs smoke::run_smoke_test on a blocking task. src-tauri/src/commands/testing/smoke.rs limits smoke tests to 25 selected requests, 30 seconds per request, and 120 seconds total. Body previews are capped at 16 KiB.

Integration points

Smoke tests use the same request resolution path as k6 validation, so failures usually point to collection variables, base URL, auth, selected request IDs, or unsupported URLs. For selection rules, see Request selection.

Entry points for modification

Change limits in src-tauri/src/commands/testing/smoke.rs. Change UI state in src/features/test/useSmokeTest.ts. Change resolution behavior in src-tauri/src/importing/runtime.rs.
