Provides parameterized testing patterns with JUnit 5, generates data-driven unit tests using @ParameterizedTest, @ValueSource, @CsvSource, @MethodSource. Creates tests that run the same logic with multiple input values. Use when writing data-driven Java tests, multiple test cases from single method, or boundary value analysis.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Parameterized Unit Tests with JUnit 5
## Overview
Provides patterns for parameterized unit tests in Java using JUnit 5. Covers `@ValueSource`, `@CsvSource`, `@MethodSource`, `@EnumSource`, `@ArgumentsSource`, and custom display names. Reduces test duplication by running the same test logic with multiple input values.
## When to Use
- Writing JUnit tests with multiple input combinations
- Implementing data-driven tests in Java
- Running same test with different values (boundary analysis)
- Testing multiple scenarios from single test method
## Instructions
1. **Add dependency**: Ensure `junit-jupiter-params` is on test classpath (included in `junit-jupiter`)
2. **Choose source**: `@ValueSource` for simple values, `@CsvSource` for tabular data, `@MethodSource` for complex objects
3. **Match parameters**: Test method parameters must match data source types
4. **Set display names**: Use `name = "{0}..."` for readable output
5. **Validate**: Run `./gradlew test --info` or `mvn test` and verify all parameter combinations execute
## Examples
### Maven / Gradle Dependency
JUnit 5 parameterized tests require `junit-jupiter` (includes params). Add `assertj-core` for assertions:

How to install
mdr add giuseppe-trisciuoglio/developer-kit/unit-test-parameterized@sha256:23868e8ef1cda757The line at the top of this page pins the label git:20260324.a02e282, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
