First behavioural test for the Yavsc.Blogs API surface. Sends a
GET on the blog index with the X-Test-Role auth bypass and asserts
the response is 200 with an empty JSON array — the in-memory
ApplicationDbContext has no rows, and BlogSpotService.Index returns
an empty enumeration.
While here, fix a routing miss: AddControllers() in the test
fixture was only scanning the test assembly, so BlogApiController
was never registered. Add the Yavsc.Blogs application part
explicitly. Without this, every request to /api/v1/blog came back
as 404 — the same symptom PostIt was seeing in production.
The POST flow lands in the next commit, once BlogApiController is
made to accept JSON (it currently requires multipart/form-data
because of Request.Form.Files).
Adds the test project that the next commit will use to assert the
blog API endpoints. The fixture inherits from the shared
WebHostFixture (commit "refactor: extract WebHostFixture…") and
wires up only the bits the blog API needs:
* In-memory ApplicationDbContext — BlogSpotService is used as-is,
no mock. The first tests will exercise the real service against
an empty table.
* Trivial IFileSystemAuthManager stub (the GET index path never
reads the file system).
* TestAuthPolicyProvider swapped in, so X-Test-Role satisfies
[Authorize("BlogScope")].
Two smoke tests verify the fixture boots and the controller
pipeline is reachable. The first behavioural test
(GET /api/v1/blog → 200) lands in the next commit.
Also promotes two xunit.v3.* package versions to the root
Directory.Packages.props so future test projects can share them.
