Run tests. Example: (covered earlier in Mock DbContext) ✅ Fast, reliable for unit or light integration tests, but not suitable for relational behaviors (like joins, transactions). 🔟 How Do You Implement TestContainers for Integration Testing?

TestContainers spins up real Docker containers (SQL Server, Redis) for integration

testing, simulating production.

Example:

using Testcontainers.MsSql;
var sqlContainer = new MsSqlBuilder()

.WithPassword("yourStrong(!)Password")

.Build();

wait sqlContainer.StartAsync();

var options = new DbContextOptionsBuilder<AppDbContext>()

.UseSqlServer(sqlContainer.GetConnectionString())

.Options;

// Use context in tests

✅ Benefits:

• Real database behavior
• CI/CD friendly
• Close to production setup
