[Copilot]

• Create src/NetEvolve.Pulse.CosmosDb/ project structure
• Implement CosmosDbOutboxOptions, CosmosDbOutboxDocument, CosmosDbOutboxRepository, CosmosDbOutboxManagement, CosmosDbExtensions
• Add Microsoft.Azure.Cosmos 3.58.0, Newtonsoft.Json 13.0.4, and Testcontainers.CosmosDb 4.11.0 to Directory.Packages.props
• Add unit tests (CosmosDbExtensionsTests, CosmosDbOutboxRepositoryTests, CosmosDbOutboxManagementTests) — all passing
• Add integration tests (CosmosDbOutboxTests) using Testcontainers.CosmosDb with the Linux emulator image
• Add CosmosDbContainerFixture, CosmosDbDatabaseServiceFixture, CosmosDbOutboxInitializer to integration test infrastructure

@copilot Add Unit and Integration Tests

Added in commit c639ca8:

Unit tests (tests/NetEvolve.Pulse.Tests.Unit/CosmosDb/):

• CosmosDbExtensionsTests — covers AddCosmosDbOutbox and UseCosmosDbOutbox null-arg validation, chaining, service registration lifetimes, and options propagation
• CosmosDbOutboxRepositoryTests — covers constructor null/empty validation and valid construction
• CosmosDbOutboxManagementTests — covers constructor null/empty validation and valid construction

Integration tests (tests/NetEvolve.Pulse.Tests.Integration/Outbox/CosmosDbOutboxTests):

• Inherits all tests from OutboxTestsBase (pending count, GetPending, batch size, mark completed/failed/dead-letter, retry scheduling, delete completed, etc.)
• Uses the Cosmos DB Linux emulator via Testcontainers.CosmosDb (mcr.microsoft.com/cosmosdb/linux/azure-cosmos-emulator:vnext-preview)
• Infrastructure: CosmosDbContainerFixture, CosmosDbDatabaseServiceFixture, CosmosDbOutboxInitializer — each test method gets an isolated container (mapped from OutboxOptions.TableName) to prevent cross-test interference

Warning

Rate limit exceeded

@samtrion has exceeded the limit for the number of commits that can be reviewed per hour. Please wait 30 minutes and 4 seconds before requesting another review.

Your organization is not enrolled in usage-based pricing. Contact your admin to enable usage-based pricing to continue reviews beyond the rate limit, or try again in 30 minutes and 4 seconds.

⌛ How to resolve this issue?

After the wait time has elapsed, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

We recommend that you space out your commits to avoid hitting the rate limit.

🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.

Please see our FAQ for further information.
