# How to Test Localization & i18n with AI > Automate localization and internationalization testing with AI agents – run the same suite across languages, currencies and regions, including geo-specific rendering. Source: https://qa.tech/use-cases/localization-testing --- You run the same test goals across multiple language and region configurations – the goals transfer, no rewriting per locale. QA.tech also offers a native geographic proxy, so the agent's traffic originates from the target country and [geo](https://docs.qa.tech/test-features/device-presets#browse-from-locale-and-timezone)\-specific rendering is tested as a real local user would see it. [Book a demo](https://qa.tech/demo) Sub-use-cases - ### Multi-language testing The same test goals run across each language configuration without rewriting – the intent transfers even when the copy changes. Each language variant needs its own crawl so the knowledge graph is accurate for that UI, so the recommended pattern is to start with one locale and add crawls per language as you expand. - ### Multi-currency pricing Running the same pricing and checkout flows under different locale settings, the agent verifies the correct currency, symbol, format and conversion appear for each region. A rounding error or misplaced symbol is a trust bug that only shows in the affected market. - ### Traffic from another country A native geographic proxy routes the agent's traffic from the target country at the infrastructure level, not via a client-side VPN – so it works even where identity-verification vendors block VPN spoofing. This is what makes "test as a user browsing from a given country" actually possible. - ### Region-specific content and geo-blocks Running the same entry flow from different regions, the agent verifies region-specific content, pricing tiers and geo-blocked features render as intended. Regional rendering bugs only appear when you're actually browsing from that region. - ### GDPR cookie-consent by region From a region-specific configuration, the agent verifies the correct consent banner appears, that accept and decline both work, and that the resulting tracking state is set. Consent flows break on deploys and CMP updates, and the breakage only affects users in specific regions. 1. 01 ## What localization testing should cover Language/locale variants, currency and number/date formatting, region-specific content and [geo](https://docs.qa.tech/test-features/device-presets#browse-from-locale-and-timezone)\-blocking, and GDPR/cookie-consent flows by region. 2. 02 ## How does AI test across languages and regions? [Test plans](https://docs.qa.tech/core-concepts/test-plans) carry locale/region configs; the same goals run per locale (each language variant needs its own [crawl](https://docs.qa.tech/core-concepts/crawling) so the graph is accurate). The geographic proxy routes traffic through a local exit IP rather than a client-side VPN, which is more reliable for geo-sensitive flows. 3. 03 ## When to run localization tests When you ship to multiple markets and geo-specific rendering, pricing or compliance must be right per region. 4. 04 ## Who needs localization and i18n testing International e-commerce and SaaS with regional pricing, geo-blocked features, or per-region compliance. 5. 05 ## How QA.tech helps Geo and locale bugs only appear from the target region – expensive to test manually. QA.tech runs the same suite per locale and originates traffic from the right country, so regional bugs surface before users in that region hit them. FAQ ## Common questions Can I run one suite across several languages? Yes – goals transfer across locales; each language variant gets its own [crawl](https://docs.qa.tech/core-concepts/crawling) for accuracy. Can QA.tech simulate traffic from a specific country? Yes – a native geographic proxy originates traffic from the target country at the infrastructure level. Does QA.tech test currency and date formatting? Yes – per-locale plans verify symbols, formats and conversions. Related use cases - [ Account & Profile Settings Testing An AI agent runs every settings action a user can take – update profile fields, change email and password, upload an avatar, toggle preferences – then verifies the changes persist after a refresh. Settings pages look simple but touch storage, auth and email, so they regress quietly.

The purchase beacon with the wrong revenue value fails the test, before it fails the month-end numbers.

QA.tech gives the agent its own inbox and phone number, so magic links, one-time passwords and confirmation emails are tested end to end, not mocked. See how Upsales replaced 320 hours of manual testing a month with this approach.
