SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses the challenge of maintaining consistent and reliable internationalization (i18n) usage in test cases, preventing errors due to hardcoded strings and discrepancies in translation references.

Core Features & Use Cases

  • Guidelines Enforcement: Provides best practices for importing locale messages and referencing i18n keys in tests.
  • Parameter Handling: Ensures string placeholders in locale messages are correctly replaced during tests.
  • Validation Automation: Uses fitness function tests to enforce adherence to i18n patterns, reducing maintenance overhead.
  • Use Case: When developing React components with translations, test code uses messages.<key>.message and applies .replace() for placeholders, thus preventing flaky tests due to translation updates.

Quick Start

Use this Skill to refactor test cases to rely solely on i18n keys and prevent locale mismatch errors.

Frequently Asked Questions about test-i18n-usage

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I prevent hardcoded strings from breaking my React i18n tests?▼

React i18n test validation involves checking that test cases consistently reference locale message keys using `messages.<key>.message` and apply `.replace()` for placeholders, preventing mismatches and hardcoded strings in test suites.

How do I handle parameter replacements in locale messages during React testing?▼

Handle parameter replacements in locale messages during React testing by applying the `.replace()` method to the `messages.<key>.message` string, ensuring placeholders are dynamically populated and validated during test execution.

Why do my React translation tests fail when locale messages are updated?▼

React translation tests fail on locale message updates when test code relies on hardcoded strings instead of i18n keys. Using `messages.<key>.message` references ensures test resilience against translation updates.

Can I automate validation to enforce i18n best practices in React test cases?▼

Yes, you can automate i18n validation in React test cases by applying fitness function tests that check for proper import of testing tools and enforce adherence to `messages.<key>.message` patterns, reducing manual maintenance overhead.

What is the best way to refactor test cases to use i18n keys instead of static text?▼

The best way to refactor test cases to use i18n keys is to replace static text assertions with `messages.<key>.message` references and ensure proper import of locale testing tools, preventing locale mismatch errors.
