Write Rust Tests
Write new Rust tests for Rust code.
Best use case
Write Rust Tests is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Write new Rust tests for Rust code.
Teams using Write Rust Tests should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.

# Write Rust Tests Write new Rust tests for Rust code. ## Arguments - `<path>`: Path to the Rust crate or file. - `<path 1> <path 2>`: Multiple crate/file paths. If a path doesn't include `src/`, assume it to be in the `src/redisearch_rs` directory. E.g. `numeric_range_tree` becomes `src/redisearch_rs/numeric_range_tree`. If a path points to a directory, consider all Rust files in that directory. ## Guidelines The generated tests must follow the guidelines outlined in [/rust-tests-guidelines](../rust-tests-guidelines/SKILL.md). ## What to test Ensure that all public APIs are tested thoroughly, including edge cases, error conditions and branches. Use [`/check-rust-coverage`](../check-rust-coverage/SKILL.md) to determine which lines are not covered by tests. ## Avoiding redundant tests Before writing each test, explicitly identify which branch or code path it will cover that no existing test already covers. An uncovered line is not sufficient justification — ask *why* it is uncovered and whether it is reachable through an already-tested entry point. Two tests are redundant if they exercise the same set of branches in the code under test. Differing only in input values that don't change control flow is not a distinct scenario. Do not write standalone tests for: - **Trivial trait delegations** — `Default`, `From`, or similar trait impls that are single-line delegations to an already-tested constructor, since they will be covered transitively. After adding tests, double check that every new test covers at least one branch that no other test (existing or new) covers. Remove any that don't.

generating-unit-tests
This skill enables Claude to automatically generate comprehensive unit tests from source code. It is triggered when the user requests unit tests, test cases, or test suites for specific files or code snippets. The skill supports multiple testing frameworks including Jest, pytest, JUnit, and others, intelligently detecting the appropriate framework or using one specified by the user. Use this skill when the user asks to "generate tests", "create unit tests", or uses the shortcut "gut" followed by a file path.
managing-snapshot-tests
This skill enables Claude to manage and update snapshot tests using intelligent diff analysis and selective updates. It is triggered when the user asks to analyze snapshot failures, update snapshots, or manage snapshot tests in general. It helps distinguish intentional changes from regressions, selectively update snapshots, and validate snapshot integrity. Use this when the user mentions "snapshot tests", "update snapshots", "snapshot failures", or requests to run "/snapshot-manager" or "/sm". It supports Jest, Vitest, Playwright, and Storybook frameworks.
running-smoke-tests
This skill runs smoke tests to verify critical application functionality. It executes pre-defined test suites that check system health, authentication, core features, and external integrations. Use this skill after deployments, upgrades, or significant configuration changes to ensure the application is operational. Trigger this skill using the terms "smoke test" or "st".
running-load-tests
Create and execute load tests for performance validation using k6, JMeter, and Artillery. Use when validating application performance under load conditions or identifying bottlenecks. Trigger with phrases like "run load test", "create stress test", or "validate performance under load".
tracking-regression-tests
This skill enables Claude to track and run regression tests, ensuring new changes don't break existing functionality. It is triggered when the user asks to "track regression", "run regression tests", or uses the shortcut "reg". The skill helps in maintaining code stability by identifying critical tests, automating their execution, and analyzing the impact of changes. It also provides insights into test history and identifies flaky tests. The skill uses the `regression-test-tracker` plugin.
running-mutation-tests
This skill enables Claude to validate test suite quality by performing mutation testing. It is triggered when the user asks to run mutation tests, analyze test effectiveness, or improve test coverage. The skill introduces code mutations, runs tests against the mutated code, and reports on the "survival rate" of the mutations, indicating the effectiveness of the test suite. Use this skill when the user requests to assess the quality of their tests using mutation testing techniques. Specific trigger terms include "mutation testing", "test effectiveness", "mutation score", and "surviving mutants".
running-integration-tests
This skill enables Claude to run and manage integration test suites. It automates environment setup, database seeding, service orchestration, and cleanup. Use this skill when the user asks to "run integration tests", "execute integration tests", or any command that implies running integration tests for a project, including specifying particular test suites or options like code coverage. It is triggered by phrases such as "/run-integration", "/rit", or requests mentioning "integration tests". The plugin handles database creation, migrations, seeding, and dependent service management.
generating-end-to-end-tests
This skill enables Claude to generate end-to-end (E2E) tests for web applications. It leverages Playwright, Cypress, or Selenium to automate browser interactions and validate user workflows. Use this skill when the user requests to "create E2E tests", "generate end-to-end tests", or asks for help with "browser-based testing". The skill is particularly useful for testing user registration, login flows, shopping cart functionality, and other multi-step processes within a web application. It supports cross-browser testing and can be used to verify the responsiveness of web applications on different devices.
conducting-browser-compatibility-tests
This skill enables cross-browser compatibility testing for web applications using BrowserStack, Selenium Grid, or Playwright. It tests across Chrome, Firefox, Safari, and Edge, identifying browser-specific bugs and ensuring consistent functionality. It is used when a user requests to "test browser compatibility", "run cross-browser tests", or uses the `/browser-test` or `/bt` command to assess web application behavior across different browsers and devices. The skill generates a report detailing compatibility issues and screenshots for visual verification. Activates when you request "conducting browser compatibility tests" functionality.
