For controller-level confidence, I add a request spec that sets Accept: text/vnd.turbo-stream.html and asserts the response includes a turbo stream action. This is faster than a system test and catches accidental template name changes (create.turbo_st

RSpec provides powerful testing tools for behavior-driven development. Shared examples reduce duplication across similar specs—I extract common behavior into reusable examples. Contexts organize tests by different scenarios. Let blocks lazily evaluate

Factory Bot creates test data with minimal boilerplate. Factories define blueprints for model creation. I use traits for variations—published posts, admin users. Sequences generate unique values. Associations automatically create related records. Tran

Unit tests verify code behavior in isolation using XCTest framework. I create test classes inheriting from XCTestCase with test prefixed methods. Each test has arrange-act-assert structure: set up dependencies, execute code, verify results with XCTAss

JUnit 5 provides a modern testing framework with @Test, @BeforeEach, @AfterEach lifecycle hooks. Mockito creates test doubles with @Mock and @InjectMocks annotations. I use when().thenReturn() to stub method responses and verify() to confirm interacti

ViewComponent brings component architecture to Rails views. Components encapsulate markup, logic, and tests in Ruby classes. I use ViewComponents for reusable UI elements—buttons, cards, modals, alerts. Components accept parameters via initializer, ke

Factory Boy eliminates boilerplate in tests by generating model instances with sensible defaults. I use Sequence for unique values, SubFactory for foreign keys, and post_generation for many-to-many relationships. The Faker integration provides realist

Laravel's testing suite built on PHPUnit makes writing tests straightforward. Feature tests simulate HTTP requests and assert responses, while unit tests focus on individual methods. I use database transactions or RefreshDatabase to reset the database
