Summary

Adds 156 xUnit tests across 25 test files in Tests/EqSamples.Tests/ covering all 5 ASP.NET Core projects. Achieves 100% line coverage (92.85% branch, 100% method) on testable code with coverlet threshold enforcement at 95%.

Test project setup (EqSamples.Tests.csproj)

  • xUnit 2.5.3, Moq 4.20.70, FluentAssertions 6.12.0, coverlet.msbuild 6.0.0
  • Extern aliases (MvcDataFiltering::, RazorAdHoc::, etc.) to manage namespace collisions across projects sharing EqDemo.Models.*
  • Coverlet <Threshold>95</Threshold> with <ThresholdType>line</ThresholdType> enforced in the csproj

Coverage by module

Module Line Branch Method
EqDemo.Angular.AdvancedSearch 100% 87.5% 100%
EqDemo.AspNetCoreRazor.AdhocReporting 100% 95.23% 100%
EqDemo.AspNetCoreMvc.DataFiltering 100% 100% 100%
EqDemo.AspNetCoreRazor.AdvancedSearch 100% 87.5% 100%
EqDemo.AspNetCoreRazor.DataFiltering 100% 87.5% 100%
Total 100% 92.85% 100%

What's tested

  • Controllers: HomeController, WeatherForecastController, ValuesController, OrderController (constructor + Index)
  • Models: All 8 entity types (Order, Employee, Customer, Product, Category, OrderDetail, Shipper, Supplier) across all 5 projects — property setters, computed properties (Name, FullName), edge cases (null/empty)
  • Page models: IndexModel, PrivacyModel, ErrorModel, AboutModelOnGet() with mocked ILogger, HttpContext
  • Identity pages: LoginModel (OnGetAsync, OnPostAsync with success/lockout/2FA/failed paths), LogoutModel (OnGet, OnPost), RegisterModel (OnGet, OnPostAsync with success/failure/AddToRole paths) — mocked SignInManager, UserManager, IEmailSender
  • Services: DefaultReportGenerator (file reading, report creation), ReportStore (user-isolated query operations via mocked IHttpContextAccessor/ClaimsPrincipal)
  • DbContext: CRUD operations, composite keys, DbSet initialization across all 5 projects using InMemoryDatabase

Excluded from coverage (auto-generated / EasyQuery infrastructure)

AspNetCoreGeneratedDocument.*, compiled Razor pages/views, Program, Startup, DbInitializeExtensions, OrderController async methods (EasyQuery EasyQueryManagerLinq), ReportStore Query-dependent methods, CustomEasyQueryManagerSql
