# JUnit 5 @RepeatedTest Demonstration

This project demonstrates the usage of JUnit 5's `@RepeatedTest` annotation to improve test reliability and handle flaky tests.

## Concepts Covered

The code examples in `src/test/java/com/ankurTutorials/junit/repeated` cover the following concepts:

1.  **Basic Repetition**: Repeating a test a specific number of times.
    - File: `ReliabilityTest.java`
2.  **Custom Display Names**: Configuring formatted names for each repetition for better reporting in CI/CD.
    - File: `CustomNameTest.java`
3.  **Metadata Injection**: Using `RepetitionInfo` to access the current repetition index and total count within the test.
    - File: `MetadataTest.java`
4.  **Lifecycle Management**: Understanding how `@BeforeEach` and `@AfterEach` interact with repeated tests (they run for *each* repetition).
    - File: `LifecycleTest.java`
5.  **Failure Thresholds**: Using the `failureThreshold` attribute (JUnit 5.10+) to stop execution early if a certain number of failures occur.
    - File: `FlakyServiceTest.java`

## Prerequisites

- Java 17 or higher
- Maven 3.6+

## How to Run

To run all tests, execute the following command in the project root:

```bash
mvn test
```

To run a specific test class:

```bash
mvn -Dtest=BasicUsageTest test
```
