# Integration Tests

Gherkin (BDD) via [Godog](https://github.com/cucumber/godog), with `testcontainers-go` for Docker orchestration.

- Feature files: `test/integration/features/*.feature`, one per endpoint or capability.
- Step definitions: `test/integration/scenario/` (container management, HTTP helpers, PDF validation).
- Entry point: `test/integration/main_test.go` (build tag: `integration`).
- Test data: `test/integration/testdata/`.

Each scenario spins up a fresh Gotenberg Docker container via testcontainers. A separate `gotenberg/integration-tools` container provides PDF validation tools (`verapdf`, `pdfinfo`, `pdftotext`).

Run `make build` before `make test-integration`. Integration tests require a Docker image.

## Selective runs

```bash
make test-integration TAGS=health
make test-integration TAGS=chromium-convert-html
make test-integration TAGS="merge,split"
make test-integration NO_CONCURRENCY=true  # disable parallel scenarios
make test-integration PLATFORM=linux/arm64 # force a specific platform
```

## Writing a new test

1. Create or update a `.feature` file in `test/integration/features/`.
2. Tag it appropriately (e.g., `@chromium @chromium-convert-html`).
3. For new tags, add them to both the `TAGS` comment block in the `Makefile` and the table above.
4. For new step definitions, add the function to `scenario/scenario.go`, register it in `InitializeScenario`, and add the step pattern to the step reference below.
5. Test data goes in `test/integration/testdata/`.

## Step reference

### Given (setup)

- `I have a default Gotenberg container`
- `I have a Gotenberg container with the following environment variable(s):` (table: key | value)
- `I have a (webhook|static) server`

### When (action)

- `I make a "(GET|HEAD)" request to Gotenberg at the "<endpoint>" endpoint`
- `I make a "(GET|HEAD)" request to Gotenberg at the "<endpoint>" endpoint with the following header(s):` (table: name | value)
- `I make a "(POST)" request to Gotenberg at the "<endpoint>" endpoint with the following form data and header(s):` (table: name | value | kind, where kind is `file`, `field`, or `header`)
- `I make <N> concurrent "(POST)" requests to Gotenberg at the "<endpoint>" endpoint with the following form data and header(s):` (same table format)
- `I wait for the asynchronous request to the webhook`

### Then (assertions)

- `the response status code should be <code>`
- `the (response|webhook request|file request|server request) header "<name>" should be "<value>"`
- `the (response|webhook request|file request|server request) cookie "<name>" should be "<value>"`
- `the (response|webhook request) body should match string:` (docstring)
- `the (response|webhook request) body should contain string:` (docstring)
- `the (response|webhook request) body should match JSON:` (docstring, use `"ignore"` for dynamic values)
- `the webhook event should match JSON:` (docstring, use `"ignore"` for dynamic values; polls for up to 5s)
- `there should be <N> PDF(s) in the (response|webhook request)`
- `there should be the following file(s) in the (response|webhook request):` (table of filenames)
- `the "<name>" PDF should have <N> page(s)`
- `the "<name>" PDF (should|should NOT) be set to landscape orientation`
- `the "<name>" PDF (should|should NOT) have the following content at page <N>:` (docstring)
- `the (response|webhook request) PDF(s) should be valid "<standard>" with a tolerance of <N> failed rule(s)` (standards: `PDF/A-1b`, `PDF/A-2b`, `PDF/A-3b`, `PDF/UA-1`, `PDF/UA-2`)
- `the (response|webhook request) PDF(s) (should|should NOT) be flatten`
- `the (response|webhook request) PDF(s) (should|should NOT) be encrypted`
- `the (response|webhook request) PDF(s) (should|should NOT) have the "<filename>" file embedded`
- `the "<name>" PDF should have <N> image(s)`
- `the Gotenberg container (should|should NOT) log the following entries:` (table of log substrings)
- `all concurrent response status codes should be <code>`
- `all concurrent responses should have <N> PDF(s)`
