test/Chirp.Infrastructure.Test/UnitTestChirpInfrastructure.cs

+        // InMemory does not enforce unique index at DB level, so check logically
+        await dbContext.Authors.AddAsync(testAuthor2);
+        await dbContext.SaveChangesAsync();
+
+        var count = await dbContext.Authors.CountAsync(a => a.Name == "Test Name" && a.Email == "test@gmail.com");
+        Assert.Equal(2, count);


This test now validates that duplicate authors can be saved (counting 2 authors with the same name/email), which is the opposite of what the test name suggests. The test "UnitTestDuplicateAuthors" should verify that duplicate authors are NOT allowed.

Since EF InMemory doesn't enforce unique constraints, consider either: (1) skipping this test with a clear explanation, or (2) testing the expected behavior at the application logic level if such validation exists outside the database layer.

test/Chirp.Infrastructure.Test/UnitTestChirpInfrastructure.cs

+        // Instead of expecting DbUpdateException, assert name is already taken
+        var existingAuthor = await dbContext.Authors.FirstOrDefaultAsync(a => a.Name == testAuthor1.Name);
+        Assert.NotNull(existingAuthor);


This test "UnitTestNoAuthorNameDuplicates" is now checking if an author already exists in the database, but the test doesn't actually attempt to add the duplicate author. The test should verify that duplicate author names are prevented.

Since testAuthor1 is never added to the database, existingAuthor will always find the seeded author from DbInitializer.SeedDatabase(), making this test pass for the wrong reason. The test should either be skipped (like the Cheep-related tests) or refactored to properly test application-level validation.

test/Chirp.Infrastructure.Test/UnitTestChirpInfrastructure.cs

+        var existingAuthor = await dbContext.Authors.FirstOrDefaultAsync(a => a.Email == testAuthor1.Email);
+        Assert.NotNull(existingAuthor);


This test "UnitTestNoEmailDuplicates" checks if an email exists but never attempts to add the duplicate author. The test should verify that duplicate emails are prevented.

Similar to the name duplicates test, testAuthor1 is never added to the database, so this test only verifies that the seeded data from DbInitializer contains the email, not that duplicate emails are prevented. This test should either be skipped or refactored to test application-level validation logic.

The SaveCheep method now includes complex entity tracking logic to handle EF InMemory conflicts, but this logic will also run in production with SQLite. This workaround for test database limitations shouldn't be part of production code.

Consider one of these approaches:

Keep production code simple and use SQLite for tests (with proper connection management per test)

If EF InMemory is required for tests, create a test-specific repository that handles these conflicts

Use a different in-memory database like SQLite in-memory mode that better matches production behavior

The current approach adds unnecessary complexity and potential bugs to production code to accommodate test infrastructure limitations.

Suggested change

// Ensure we only track a single Cheep instance per key value

Cheep cheepToTrack = cheep;

if (cheep.CheepId != 0)

{

var trackedEntry = _dbContext.ChangeTracker.Entries<Cheep>()

.FirstOrDefault(e => e.Entity.CheepId == cheep.CheepId);

if (trackedEntry != null)

{

// Reuse the tracked entity to avoid double-tracking conflicts

cheepToTrack = trackedEntry.Entity;

// Optionally update its scalar properties from the incoming cheep

cheepToTrack.Text = cheep.Text;

cheepToTrack.AuthorId = cheep.AuthorId;

cheepToTrack.TimeStamp = cheep.TimeStamp;

}

}

if (_dbContext.Entry(cheepToTrack).State == EntityState.Detached)

{

await _dbContext.Cheeps.AddAsync(cheepToTrack);

}

// Ensure the cheep is associated with the given author

cheep.AuthorId = author.AuthorId;

author.Cheeps.Add(cheep);

await _dbContext.Cheeps.AddAsync(cheep);

The workflow now only runs tests from Chirp.Infrastructure.Test project, excluding all other test projects. If there are other test projects (like Chirp.Web.Playwright.Test based on removed Playwright setup), they will not be executed at all.

While the PR description mentions excluding Playwright tests, silently excluding all other potential test projects without explicitly listing them could hide test failures. Consider being more explicit about which test projects are being excluded and why.

-    [Fact]
+    [Fact(Skip = "Fails under EF InMemory due to Cheep ID tracking conflicts; GetLikedCheeps logic is covered elsewhere.")]


Similar to the other skipped test, this test has been refactored to work with InMemory by fetching the tracked instance from the context before using it. If the refactoring resolves the tracking conflicts, the Skip attribute should be removed. If it still fails, clarify why the refactoring didn't fix the issue.

-        [Fact]
+        [Fact(Skip = "Temporarily disabled due to EF Sqlite version bug in test web host.")]


The skip reason "Temporarily disabled due to EF Sqlite version bug in test web host" is vague and doesn't provide enough information for future maintainers. The integration tests use SQLite (via CustomWebApplicationFactory), and the issue might be related to the version mismatch between Microsoft.Data.Sqlite (8.0.10) and Microsoft.EntityFrameworkCore packages.

Consider:

Adding more details about what the specific bug is (error message, issue link, etc.)

Creating a tracking issue to re-enable these tests

Verifying if upgrading all Identity packages to 8.0.10 resolves the issue

Suggested change

[Fact(Skip = "Temporarily disabled due to EF Sqlite version bug in test web host.")]

[Fact(Skip = "Disabled due to EF Core/SQLite version mismatch in CustomWebApplicationFactory test host (Microsoft.Data.Sqlite 8.0.10 vs older Microsoft.EntityFrameworkCore.* packages), causing startup/migration failures when using the in-memory SQLite database. See tracking issue: https://github.com/your-org/your-repo/issues/123 to re-enable after aligning all EF/Identity packages to 8.0.10 or later.")]

      <PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="8.0.0" />
      <PackageReference Include="Microsoft.AspNetCore.Identity.UI" Version="8.0.0" />


The Chirp.Infrastructure project still uses version 8.0.0 for Microsoft.AspNetCore.Identity.EntityFrameworkCore and Microsoft.AspNetCore.Identity.UI packages, while the test project and other EF Core packages have been updated to 8.0.10. This version inconsistency could lead to runtime conflicts or unexpected behavior.

All Microsoft.AspNetCore and Microsoft.EntityFrameworkCore packages should be updated to the same version (8.0.10) for consistency.

test/Chirp.Infrastructure.Test/UnitTestCheepRepository.cs



-    [Fact]
+    [Fact(Skip = "Fails under EF InMemory due to Cheep ID tracking conflicts; SaveCheep behavior is covered by other tests.")]


The skip reason mentions "Fails under EF InMemory due to Cheep ID tracking conflicts" but the test has been refactored to work with InMemory by avoiding FindAsync and using FirstAsync instead. If the refactored test now works correctly, the Skip attribute should be removed. If it still fails, the skip reason should explain why the refactoring didn't resolve the issue.
