Q1Domain Verified

In JUnit 5, what is the primary mechanism for declaring test methods, and how does it differ conceptually from JUnit 4's `@Test` annotation?

`@Test` annotation, which remains the core annotation for test methods but is now part of the `org.junit.jupiter.api` package and offers enhanced metadata capabilities.

`@Test` annotation, which is retained for backward compatibility and functions identically to JUnit 4.

`@Execution(@ExecutionMode.CONCURRENT)`, which enables parallel execution and is the new standard for test methods.

`@Testable`, a new annotation introduced in JUnit 5 to explicitly mark methods intended for testing, distinct from general-purpose methods.

Q2Domain Verified

When migrating from JUnit 4 to JUnit 5, what is the recommended approach for handling assumptions within tests, and why is this preferred over JUnit 4's `Assume` class?

Leverage `org.junit.jupiter.api.Assumptions.assumeTrue()` or `assumeFalse()`, as JUnit 5 has deprecated the older `Assume` class in favor of a more modern, assertion-like approach.

Utilize `org.junit.jupiter.api.Assumptions.assumeThat()`, which provides a more fluent and expressive API for defining test assumptions.

Use `org.junit.jupiter.api.Assertions.assertAll()`, which allows for grouping of conditional assertions.

Employ `org.junit.jupiter.api.extension.Condition` interfaces, which offer a more programmatic and granular control over assumption evaluation.

Q3Domain Verified

Consider a scenario where you have multiple test methods that require the same setup and teardown logic. In JUnit 5, which approach provides the most flexible and maintainable way to manage this shared lifecycle behavior, especially when dealing with multiple test classes?

Implementing the `BeforeEachCallback` and `AfterEachCallback` interfaces from the `org.junit.jupiter.api.extension` package.

Using `@BeforeEach` and `@AfterEach` annotations within each test class, ensuring encapsulation of setup/teardown per class.

Creating a custom extension by implementing `BeforeAllCallback`, `AfterAllCallback`, `BeforeEachCallback`, and `AfterEachCallback` and registering it with the `@ExtendWith` annotation.

Declaring static `@BeforeAll` and `@AfterAll` methods in a base test class that other test classes extend, leveraging inheritance.
