tests
BDD scenarios for the video upload feature, written in Gherkin and run by gobdd.
The suite is black box: it speaks nothing but HTTP to a running cms, so
the same scenarios run against the local docker-compose stack and against a
deployed environment. It is its own Go module (thamanyah/tests) and imports
nothing from cms/ — the API is the contract under test, not the code.
The upload to storage is a plain PUT to the presigned URL the API hands out,
with no AWS SDK involved, because that is exactly what a real client does.

Running
The suite needs a live cms with its database migrated and its buckets
provisioned. From the repo root:
docker compose up -d # localstack + infra + cms
docker exec cms ./cms migrate # see "Migrations" below
cd tests && go test ./...
If nothing is serving, the suite skips rather than fails, so go test ./...
in a fresh checkout stays green.
Point it at another environment with CMS_BASE_URL (default
http://localhost:8081):
CMS_BASE_URL=https://cms.example.com go test -v ./...
Use -v to see the Gherkin: gobdd nests a Go subtest per feature, scenario and
step, so the step text shows up in the test output.
Migrations
docker-compose.yml starts cms in server mode only. The migrate container
that runs ./cms migrate to completion before the service starts exists in the
ECS task definition (runMigrations in infrastructure/main.go), not in
compose — so a freshly created local database has no schema and every scenario
fails with relation "categories" does not exist. Run docker exec cms ./cms migrate once after the stack first comes up.
What the scenarios cover
Both steps of the upload flow, end to end:
- listing the categories a video can be filed under, and the shape of that list
- issuing an upload slot for MP4 and QuickTime, including that the storage key is generated rather than taken from the client's file name
- refusing a slot for every other media type, and for a body that is not JSON
- uploading the file to the presigned URL and registering it: the record comes
back
processing, under the key from the slot, with a transcoding job id and the categories and metadata that were sent - refusing to register: a file that was never uploaded, a missing title, no category, and a storage key this API never issued
- answering 404 for a category id no category has, kept distinct from the 500 the category lookup itself failing produces
@known-gap
One scenario is tagged @known-gap. It passes — it pins down what the service
does today, where that differs from what it is documented to do:
- registering the same upload twice answers 500.
videos.storage_keyisUNIQUE, so the retry the API's own error message invites ("retry this request with the same 'key'") fails the insert — after a second MediaConvert job has already been queued for the same file.
Fixing it means changing the scenario alongside the handler. It is tagged so it
is easy to find, and so it can be excluded with
gobdd.WithIgnoredTags("@known-gap") if that is ever wanted.
Adding a scenario
Write it in features/. If it needs a step that does not exist yet, add the
function to steps_test.go and register it in TestVideoUpload. Two things to
know about gobdd:
- Step patterns are matched unanchored, and the first registered pattern
that matches wins. Anchor every pattern with
^…$, as the existing ones do, or a new step can silently shadow an old one. - State moves between steps through the
*worldin the gobdd context, not package variables — gobdd clones the context between theBackgroundand the scenario, so the world is held by pointer.
Scenarios write real rows and real objects, and nothing cleans up after them. That is fine against LocalStack, which is disposable; think twice before pointing the suite at anything that is not.
