Migrate integration tests from TestServerBuilder to TestWebApplicationFactory #51

Krishanthaudayakumara · 2025-09-19T08:21:51Z

Description / Motivation

This PR removes the legacy TestServerBuilder usage from the test and benchmark suites and migrates integration tests to the WebApplicationFactory<TestWebApplicationProgram> pattern (TestWebApplicationFactory). It preserves each fixture’s middleware and service ordering (rendering engine, experience editor, tracking, localization, forwarded headers, visitor identification, etc.) and keeps per-test substitutes/mock handlers where tests rely on specific layout responses.

Key changes

Replaced TestServerBuilder/TestServer with WebApplicationFactory<TestWebApplicationProgram> in all integration tests and benchmarks.
Preserved and validated middleware ordering per-fixture (kept attribute-based rendering behavior by omitting global UseSitecoreRenderingEngine where necessary).
Replaced direct TestServer.CreateClient()/Services usage with factory.CreateClient()/factory.Services and updated disposal.
Added/kept per-test ISitecoreLayoutClient and ISitecoreLayoutSerializer substitutes where fixtures require specific SitecoreLayoutResponse content (e.g., Experience Editor cases that map databaseName = "master").
Migrated benchmarks to use WebApplicationFactory and registered mock HttpMessageHandlers via HttpClientFactory for consistent handler injection.
Fixed compilation issues and runtime startup ordering (ensuring TestServerDefaults runs before per-fixture mock registrations so mocks are not overwritten).
Minor style/analyzer warnings remain (XML docs/usings/ordering); these are low-risk and can be cleaned in a follow-up.

Fixes #36

Testing

The Unit & Intergration tests are passing.
I have added the necessary tests to cover my changes.

Pull Request Overview

This PR migrates integration tests from the legacy TestServerBuilder pattern to the standard WebApplicationFactory<TestWebApplicationProgram> pattern for ASP.NET Core integration testing. The migration preserves middleware ordering and per-test service configuration while modernizing the test infrastructure.

Replaced TestServerBuilder/TestServer with WebApplicationFactory<TestWebApplicationProgram> across all integration tests and benchmarks
Preserved middleware and service ordering for each test fixture while updating configuration patterns
Migrated benchmarks to use the new factory pattern with proper dependency injection
