They test cleanly in Vitest without booting the\nframework.</p>\n<h2>Step 1: Confirm Vitest is installed</h2>\n<p>If the project has no <code>vitest</code> dependency, run <code>scaffold-tests</code> first (or\nprompt the user to). This skill does not handle Vitest setup.</p>\n<h2>Step 2: Enumerate API handlers</h2>\n<p>MCP: when the pracht MCP server is registered (<code>pracht dev-mcp</code>), prefer its\n<code>inspect_routes</code>/<code>inspect_api</code>/<code>inspect_build</code>/<code>doctor</code>/<code>verify</code>/<code>generate_*</code>\ntools over shelling out. <code>pracht inspect</code> needs the pracht plugin in the vite\nconfig.</p>\n<pre><code>pracht inspect api --json\n</code></pre>\n<p>For each entry, capture: <code>path</code> (URL), <code>file</code> (source path), and the exported\n<code>methods</code> (e.g., <code>[\"GET\", \"POST\"]</code>). Note: <code>methods</code> only lists named HTTP\nmethod exports — a default-export dispatcher yields <code>methods: []</code>, never\n<code>[\"default\"]</code>. Current <code>@pracht/cli</code> versions also report a\n<code>hasDefaultHandler</code> boolean; use it when present. If the field is absent\n(older CLI) and <code>methods</code> is empty, fall back to the grep in Step 7 to detect\na default dispatcher.</p>\n<p>Ask the user which subset to scaffold or accept paths via <code>$ARGUMENTS</code>.</p>\n<h2>Step 3: Generate one test per handler file</h2>\n<p>Place tests next to the handler with <code>.test.ts</code> suffix\n(<code>src/api/users/[id].test.ts</code>). Use <code>createApiArgs()</code> from <code>@pracht/test</code>\n(add it as a dev dependency if missing) to construct <code>ApiRouteArgs</code>:</p>\n<pre><code>import { describe, it, expect } from \"vitest\";\nimport { createApiArgs, readJson } from \"@pracht/test\";\nimport { GET, POST /* import only what the handler exports */ } from \"./&lt;file&gt;\";\n\ndescribe(\"&lt;METHOD&gt; &lt;api-path&gt;\", () =&gt; {\n  it(\"returns 200 on a valid request\", async () =&gt; {\n    const res = await GET(createApiArgs({ url: \"&lt;api-path&gt;\" }));\n    expect(res).toBeInstanceOf(Response);\n    expect(res.status).toBe(200);\n  });\n});\n</code></pre>\n<p>Pass <code>params</code> for dynamic segments, <code>body</code> for JSON payloads (plain objects\nare JSON-encoded with the right <code>Content-Type</code>), and use <code>submitForm()</code> for\nform-encoded/multipart POSTs — it drives the same <code>FormData</code> parsing path\n<code>defineApi()</code> uses.</p>\n<h2>Step 4: Generate method-specific cases</h2>\n<p>For each exported method, emit the smallest realistic case:</p>\n<table>\n<thead>\n<tr>\n<th>Method</th>\n<th>Default case</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td><code>GET</code></td>\n<td>Plain GET → <code>expect(res.status).toBeLessThan(400)</code></td>\n</tr>\n<tr>\n<td><code>POST</code></td>\n<td>POST with empty <code>FormData</code> → assert validation behavior</td>\n</tr>\n<tr>\n<td><code>PUT</code></td>\n<td>PUT with JSON body → assert 200 or auth-required (401/403)</td>\n</tr>\n<tr>\n<td><code>PATCH</code></td>\n<td>PATCH with partial body → assert 200 or 422</td>\n</tr>\n<tr>\n<td><code>DELETE</code></td>\n<td>DELETE on a real-shaped path → assert 200/204 or 401</td>\n</tr>\n</tbody>\n</table>\n<p>For dynamic segments (<code>[id].ts</code> → <code>/api/users/:id</code>), pick a placeholder param\n(e.g., <code>id: \"test-1\"</code>) and pass it via <code>params</code>. Surface in the report that\nthe user may need to provide a real fixture.</p>\n<h2>Step 5: Detect auth-gated APIs</h2>\n<p>API routes do NOT appear in <code>pracht inspect routes --json</code> (that report\ncovers page routes only) and <code>pracht inspect api --json</code> has no middleware\nfield. API middleware is the single global list configured as\n<code>defineApp({ api: { middleware: [...] } })</code> — read the manifest source\n(<code>src/routes.ts</code> or wherever <code>defineApp</code> lives) to see whether an auth\nmiddleware is in that list. If it is, scaffold an extra test:</p>\n<pre><code>it(\"rejects unauthenticated requests\", async () =&gt; {\n  const res = await POST(createApiArgs({ url: \"&lt;api-path&gt;\", method: \"POST\" }));\n  expect([401, 403, 302]).toContain(res.status);\n});\n</code></pre>\n<p>Note: middleware does NOT run when calling the handler directly — this test\nverifies the handler's own defense if it has one. If the only defense is\nmiddleware, mention that in the report and recommend an integration test that\ngoes through the framework's request pipeline (out of scope for this skill).\nThe same applies to the framework's built-in CSRF check: <code>requireSameOrigin</code>\n(on by default) rejects cross-origin state-changing API requests in the real\npipeline but never runs in direct-invocation tests.</p>\n<h2>Step 6: Validate JSON shape</h2>\n<p>For handlers that return <code>Response.json(...)</code>, generate:</p>\n<pre><code>it(\"returns JSON with the expected keys\", async () =&gt; {\n  const res = await GET(createApiArgs({ url: \"&lt;api-path&gt;\" }));\n  expect(res.headers.get(\"content-type\")).toMatch(/application\\/json/);\n  const body = await readJson(res);\n  expect(body).toEqual(expect.objectContaining({ /* fill in */ }));\n});\n</code></pre>\n<h2>Step 7: Default-handler dispatchers</h2>\n<p>If the handler exports <code>default</code> (one function dispatching on\n<code>request.method</code>), generate a test per HTTP method the handler appears to\nsupport (grep for <code>request.method ===</code> patterns inside the file).</p>\n<h2>Step 8: Run</h2>\n<pre><code>pnpm test\npracht verify --json\n</code></pre>\n<p>Report passes/failures. Mark generated assertions as TODO so the user knows\nto tighten them.</p>\n<h2>Rules</h2>\n<ol>\n<li>Use <code>pracht inspect api --json</code> as the inventory — do not glob.</li>\n<li>Only import methods the handler actually exports; otherwise the test fails\nto load.</li>\n<li>Direct-handler invocation skips middleware AND the default-on\n<code>requireSameOrigin</code> CSRF check. Be explicit in the report.</li>\n<li>Test files live next to handlers with <code>.test.ts</code> suffix unless the\nproject already uses a <code>__tests__/</code> convention (detect and match).</li>\n<li>Never overwrite existing test files; emit a <code>.next.test.ts</code> and tell the\nuser to merge.</li>\n</ol>\n<p>$ARGUMENTS</p>\n","files":[{"path":"SKILL.md","sizeBytes":6044,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
