Provides patterns for testing utility classes, static methods, and helper functions. Validates pure functions, null handling, edge cases, and boundary conditions. Generates AssertJ assertions and @ParameterizedTest for string utils, math utils, validators, and collection helpers. Use when testing utils, test helpers, helper functions, static methods, or verifying utility code correctness.
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
# Unit Testing Utility Classes and Static Methods ## Overview This skill generates tests for utility classes with static helper methods and pure functions. It provides patterns for testing null handling, edge cases, boundary conditions, and common utilities like string manipulation, calculations, data validation, and collections. Pure functions require no mocking. ## When to Use Use this skill when: - Writing tests for utility/helper classes with static methods - Testing pure functions with no state or side effects - Testing string manipulation, formatting, or transformation utilities - Testing calculation, conversion, or math helper functions - Testing data validation and formatter utilities - Verifying null/empty input handling in utility code - Testing collections or array helper methods ## Instructions 1. **Create test class**: Name it after the utility (e.g., `StringUtilsTest`) 2. **Test happy path**: Valid inputs with expected outputs 3. **Test edge cases**: null, empty, whitespace, single elements 4. **Test boundary conditions**: max/min values, large numbers, precision 5. **Use descriptive names**: `shouldCapitalizeFirstLetter` instead of `test1` …

How to install
mdr add giuseppe-trisciuoglio/developer-kit/unit-test-utility-methods@sha256:0576f33dd1711e97The 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.
