icu_testdata

icu_testdata is a unit testing crate for ICU4X.

The crate exposes data providers with stable data useful for unit testing. The data is based on a CLDR tag and a short list of locales that, together, cover a range of scenarios.

The crate exposes three kinds of providers, corresponding to the three types of constructors in ICU:

• [unstable], [unstable_no_fallback]
• [any], [any_no_fallback]
• [buffer], [buffer_no_fallback] (buffer Cargo feature)

Examples

use icu::locid::locale;
use icu_provider::hello_world::HelloWorldFormatter;

// Unstable constructor
HelloWorldFormatter::try_new_unstable(
    &icu_testdata::unstable(),
    &locale!("en-CH").into(),
).unwrap();

// AnyProvider constructor
HelloWorldFormatter::try_new_with_any_provider(
    &icu_testdata::any(),
    &locale!("en-CH").into(),
).unwrap();

// BufferProvider constructor (`icu` with `serde` feature, `icu_testdata` with `buffer` feature)
HelloWorldFormatter::try_new_with_buffer_provider(
    &icu_testdata::buffer(),
    &locale!("en-CH").into(),
).unwrap();

// Without fallback the locale match needs to be exact
HelloWorldFormatter::try_new_unstable(
    &icu_testdata::unstable_no_fallback(),
    &locale!("en-CH").into(),
).is_err();

HelloWorldFormatter::try_new_unstable(
    &icu_testdata::unstable_no_fallback(),
    &locale!("en").into(),
).unwrap();
