## What it does

The skill loads when you create or fix elastic-package tests. It covers three areas: pipeline fixtures (`.log`/`.json` inputs, `*-expected.json` output, config files), system tests under `_dev/test/system/` and `_dev/deploy/` with mock APIs, and script tests for failure paths, API error handling and package upgrades.

\`SKILL.md` itself only routes you. The detail sits in `references/`. Pipeline work points to `references/pipeline-testing.md`. Any system test starts with `references/system-testing.md`, then adds a file for the input type: `cel`, `tcp`/`udp`, `http_endpoint`, `logfile`/`filestream`, `kafka`/`gcp-pubsub`, or cloud storage. Script tests use `references/script-testing.md`. When an integration takes several input types, load the generic file plus each matching one.

Two files serve subagents: `references/builder-setup-subagent-guidance.md` and `references/builder-system-test-subagent-guidance.md`. The orchestrator passes the path in the task prompt and the subagent reads the file in its own context, so pasting the contents into the prompt is wrong. Processor design for ingest pipelines, CEL program development and picking elastic-package commands are handled by other skills, not this one.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add elastic/integration-skills --skill integration-testing -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/integration-testing/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/integration-testing/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add elastic/integration-skills --skill integration-testing -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/integration-testing/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add elastic/integration-skills --skill integration-testing -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/integration-testing/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install elastic/integration-skills integration-testing
```

2. **Manually: put the files in place**
- File: `.github/skills/integration-testing/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add elastic/integration-skills --skill integration-testing -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/elastic/integration-skills --path skills/integration-testing
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/integration-testing/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add elastic/integration-skills --skill integration-testing -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/elastic/integration-skills/tree/HEAD/skills/integration-testing/SKILL.md

## When to use it
- build pipeline fixtures and check them against `*-expected.json`
- wire a mock API for a system test
- track down why a system test reports 0 hits
- write a script test for an error path or a package upgrade
- pick the right reference file for a data stream input type

## Example prompts
- Help me write the pipeline test fixtures for this data stream and check the expected output
- My system test fails with 0 hits — figure out what is wrong with the mock API
- I need a script test for an API error and a package upgrade, walk me through the txtar format

# integration-testing

## When to use

Load this skill whenever tasks include:
- authoring or debugging pipeline test fixtures (`.log`/`.json` inputs, `*-expected.json` output, config files)
- setting up or debugging system tests (`_dev/test/system/`, `_dev/deploy/`, mock APIs, 0-hits failures)
- writing script tests for failure paths, API error handling, or package upgrades

## When not to use

Do not use this skill as the primary guide for:
- ingest pipeline processor design and architecture (`ingest-pipelines`)
- CEL program development (`cel-programs`)
- broad elastic-package command selection and stack lifecycle (`elastic-package-cli`)

## Reference files — load the one that matches your test type

| Test type | Load when | Reference file |
|-----------|-----------|----------------|
| Pipeline tests | Writing fixtures, config files, expected output, debugging pipeline test failures | `references/pipeline-testing.md` |
| System tests (generic) | Always load for any system test work — config fields, commands, teardown, debugging | `references/system-testing.md` |
| Script tests | txtar failure/error tests, upgrade tests, mock services embedded in txtar | `references/script-testing.md` |

### System test input-specific references

In addition to the generic `system-testing.md`, load the reference file matching your data stream's input type:

| Input type | Reference file |
|------------|----------------|
| `cel` | `references/system-testing-cel.md` |
| `tcp`, `udp` | `references/system-testing-tcp-udp.md` |
| `http_endpoint` | `references/system-testing-http-endpoint.md` |
| `logfile`, `filestream` | `references/system-testing-logfile.md` |
| `kafka`, `gcp-pubsub` | `references/system-testing-kafka-pubsub.md` |
| `aws-s3`, `gcs`, `azure-blob-storage`, `azure-eventhub` | `references/system-testing-cloud-skip.md` |
```
