Utilities (68 tests):
- HashValidator: SHA256/MD5 computation, file validation, cancellation
- CompatibilityChecker: OS/architecture compatibility, platform detection
- VersionComparer: SemVer 2.0 compliance including prerelease handling
- RestartHelper: Restart mode validation
Models (18 tests): DriverInfo, UpdateStrategy, UpdateResult, ErrorInfo structure validation
Entry Point (9 tests): GeneralDrivelution factory methods, quick update flows, validation

+    <ProjectReference Include="..\GeneralUpdate.Drivelution\GeneralUpdate.Drivelution.csproj" />
+  </ItemGroup>


This new test project isn’t referenced by src/c#/GeneralUpdate.sln (no DrivelutionTest entry), so a solution-level dotnet test run won’t execute these tests. Add the project to the solution (or update the test/CI invocation to include this csproj explicitly) so coverage is actually exercised.

+    public void Create_WithoutParameters_ReturnsNonNullInstance()
+    {
+        // Arrange & Act
+        var updater = DriverUpdaterFactory.Create();
+
+        // Assert
+        Assert.NotNull(updater);
+        Assert.IsAssignableFrom<IGeneralDrivelution>(updater);


DriverUpdaterFactory.Create() throws PlatformNotSupportedException on MacOS/unsupported platforms, so this test will fail when run there. Consider branching on GetCurrentPlatform() and asserting the exception for MacOS/Unknown (or skipping), so the test suite is portable across runners.

+        var updater = GeneralDrivelution.Create();
+
+        // Assert
+        Assert.NotNull(updater);
+    }


These Create(...) entry-point tests assume the platform is supported, but GeneralDrivelution.Create() will throw on MacOS/unsupported platforms (via DriverUpdaterFactory.Create). To avoid platform-dependent failures, gate the test (skip) or assert the expected exception when GetPlatformInfo().IsSupported is false.

This test calls GeneralDrivelution.QuickUpdateAsync, which can execute real driver installation steps when run with admin/root privileges (Windows: ExecuteDriverInstallationAsync, Linux: ExecuteDriverInstallationAsync). To keep this as a safe unit test, avoid using an actual file path (force validation failure early), or explicitly skip when running elevated so the test can’t modify the host system.

src/c#/DrivelutionTest/GeneralDrivelutionTests.cs

+            // Assert - Should return a boolean value without throwing
+            // No assertion needed - the test passes if no exception is thrown


ValidateAsync_WithMinimalDriverInfo_ReturnsBooleanResult doesn’t assert anything about the returned value (the result is unused). If the intention is “doesn’t throw”, rename the test accordingly; otherwise add an assertion that verifies the expected true/false outcome for the given input so the test actually detects regressions.

Suggested change

// Assert - Should return a boolean value without throwing

// No assertion needed - the test passes if no exception is thrown

// Assert - validation should succeed for an existing minimal driver file

Assert.True(result);

+        Assert.True(RestartHelper.IsRestartRequired(RestartMode.None) == false);
+        Assert.True(RestartHelper.IsRestartRequired(RestartMode.Prompt) == true);


This “callable” test is asserting boolean comparisons via Assert.True(x == false/true), which reduces readability and makes failures less clear. Prefer Assert.False(...) / Assert.True(...) directly (or remove the redundancy since IsRestartRequired is already covered by the focused tests above).

Suggested change

Assert.True(RestartHelper.IsRestartRequired(RestartMode.None) == false);

Assert.True(RestartHelper.IsRestartRequired(RestartMode.Prompt) == true);

Assert.False(RestartHelper.IsRestartRequired(RestartMode.None));

Assert.True(RestartHelper.IsRestartRequired(RestartMode.Prompt));

+            };
+
+            var strategy = new UpdateStrategy
+            {
+                RequireBackup = false,
+                RetryCount = 1,
+                RetryIntervalSeconds = 1
+            };
+
+            // Act

+            Assert.True(Enum.IsDefined(typeof(UpdateStatus), result.Status));
+        }


Same concern as the other QuickUpdate test: if the runner has elevated privileges, this can progress past validation and attempt a real driver install. To keep tests non-invasive, force an early failure (e.g., non-existent path) or skip when elevated so CI/dev machines can’t be modified by running the unit suite.

+        {
+            var driverInfo = new DriverInfo
+            {
+                Name = "Test Driver",
+                Version = "1.0.0",
+                FilePath = testFilePath
+            };
+
+            var cts = new CancellationTokenSource();
+            cts.Cancel();
+
+            // Act & Assert
+            // Should either complete quickly or throw cancellation exception
+            var exception = await Record.ExceptionAsync(
+                () => GeneralDrivelution.QuickUpdateAsync(driverInfo, cts.Token));
+
+            // Either succeeded, failed gracefully, or was cancelled
+            Assert.True(exception == null || exception is OperationCanceledException);
+        }


This cancellation test still invokes QuickUpdateAsync, which may have side effects if the update starts before cancellation is observed (especially if running elevated). Consider using an input that guarantees validation fails immediately, or explicitly skip when running elevated to avoid any chance of executing installation steps during tests.
