Add Test

Add Test

Add an integration test for a specific tool in an existing collection. This skill creates a single test file following the collection's established test patterns.

Use this skill when:

• You added a new tool with /add-tool and want to test it separately
• You manually created or modified a tool and need a test
• You deleted a test and need to recreate it
• /build-tools-tests skipped the collection because tests already exist

Prerequisites

Before running, ensure:

1. The collection exists (src/umbraco-api/tools/{collection}/index.ts)
2. The test infrastructure exists (src/umbraco-api/tools/{collection}/__tests__/setup.ts) — if not, tell the user to run /build-tools-tests {collection} first
3. The project compiles: npm run compile
4. The Umbraco instance is running
5. An API user exists — remind the user: "You need to create an API user via the Umbraco backoffice UI: Settings > Users, with Client ID umbraco-back-office-mcp and Client Secret 1234567890"

Arguments

• Collection name (required): the collection containing the tool (e.g. /add-test form)
• Tool name (optional): the specific tool to test (e.g. /add-test form copy-form)

If no tool name is provided, compare the tools in the collection index against existing test files and present the untested tools to the user.

Critical Rules

TEST INFRASTRUCTURE MUST EXIST. This skill does not create setup.ts, builders, or helpers. If they don't exist, tell the user to run /build-tools-tests {collection} first.

ONE FILE AT A TIME. Create one test file, compile, run, fix. Then move to the next if testing multiple tools.

RUN COMMANDS SEPARATELY. Always run compile and test as separate Bash calls. Never chain with &&.

REAL API — NO MOCKING. These are integration tests against a real Umbraco instance. Do NOT create mock infrastructure.

ONLY CREATE FILES IN __tests__/. Do NOT modify tool files, collection indexes, API client files, or mock handlers.

Workflow

Step 0: Identify the Tool

If a tool name was provided, verify it exists in the collection index.

If no tool name was provided:

1. Read src/umbraco-api/tools/{collection}/index.ts to get the list of tools
2. List existing test files in src/umbraco-api/tools/{collection}/__tests__/
3. Identify tools without test files
4. Present the untested tools and ask which to test

Step 1: Read Existing Patterns

Read the existing test infrastructure to match patterns:

• src/umbraco-api/tools/{collection}/__tests__/setup.ts — imports, re-exports, builder/helper names
• One or two existing test files — to match the assertion style, snapshot usage, builder patterns
• The tool file itself — to understand input schema, handler, slices

If setup.ts doesn't exist, stop and tell the user to run /build-tools-tests {collection} first.

Step 2: Check Builder Coverage

Read the existing builder (__tests__/helpers/{entity}-builder.ts) to check if it supports creating the data needed for this tool's test.

If the builder needs a new method (e.g. withCopiedFrom() for a copy tool):

1. Add the method to the existing builder
2. Compile to verify
3. Continue

If the helper needs a new query method, add it to the existing helper file.

Step 3: Create Test File

Use the integration-test-creator agent.

Create src/umbraco-api/tools/{collection}/__tests__/{action}-{entity}.test.ts:

• Import from ./setup.js (matching the existing test import style)
• Use the existing builder for test data setup
• Follow snapshot testing for success cases (createSnapshotResult + toMatchSnapshot)
• Use assertion testing for error cases (expect(result.isError).toBe(true))
• 1 happy path test + 1 error test (2-3 tests maximum)
• Clean up created data in afterEach
• Paginated tools (with skip/take): Don't wrap — withStandardDecorators already applied withCursorPagination, so the imported tool's handler takes cursor and wrapping again is a no-op. Pass {} for the first page, encodeCursor({ s: 0, t: N }) from @umbraco-cms/mcp-server-sdk to force a small page, then the response's nextCursor for page two. See /build-tools-tests SKILL.md for full cursor pagination examples.

After creating:

npm run compile

npm test -- __tests__/{collection}/{action}-{entity}.test.ts

Fix any failures before proceeding.

Step 4: Validate

Use the integration-test-validator agent to check the new test follows collection patterns:

• Uses setupTestEnvironment() in describe block
• Uses createMockRequestHandlerExtra() for handler calls
• Uses snapshot testing for success responses
• Uses the collection's builder for data setup
• Constants use TEST_ prefix
• Reasonable test count (2-3 per tool)

Step 5: Report

Report what was done:

• Test file created (path)
• Tests passing (count)
• Any builder/helper updates made
• Any validation findings
