React Native Pseudo Localization

Pseudolocalization

Pseudolocalization (or pseudo-localization) is a software testing method used for testing internationalization aspects of software. Instead of translating the text of the software into a foreign language, as in the process of localization, the textual elements of an application are replaced with an altered version of the original language.

English	Pseudo Language

Inspiration

Inspired by Brian Holt talk on ReactRally and tryggvigy GitHub repository.

Why?

To catch localization problems like:

• Translated text that is significantly longer than the source language, and does not fit within the UI constraints, or which causes text breaks at awkward positions.
• Font glyphs that are significantly larger than, or possess diacritic marks not found in, the source language, and which may be cut off vertically.
• Application code that assumes all characters fit into a limited character set, such as ASCII or ANSI, which can produce actual logic bugs if left uncaught.
