Crate chrome_for_testing 

Chrome for Testing API Client

This crate provides programmatic access to “chrome-for-testing” JSON APIs, which are used to retrieve version details and other relevant information about Chrome and ChromeDriver for testing purposes.

Modules Overview

• chromedriver: ChromeDriver specific utilities, such as log level configuration.

API Endpoints

The crate leverages the following JSON API endpoints:

• Last Known Good Versions: Recent good versions for each release channel (Stable/Beta/Dev/Canary). Perfect if you just need the “latest stable” version for example.

• Known Good Versions: All known good versions. Longer API response, not pre-grouped per release channel. Good fit if you have a hardcoded old version that you want to resolve a download URL for.

For detailed documentation on these APIs, see the official Chrome for Testing documentation.

Features

• Ease of Use: Simplifies interaction with Chrome’s testing-related APIs.
• Type-Safe Deserialization: Automatically maps JSON responses to Rust structs for seamless API interaction.
• Asynchronous Support: Fully asynchronous.

Example Usage

#[tokio::main]
async fn main() {
    use chrome_for_testing::KnownGoodVersions;

    let client = reqwest::Client::new();
    match KnownGoodVersions::fetch(&client).await {
        Ok(data) => println!("Successfully fetched Chrome versions: {data:?}"),
        Err(e) => println!("Error occurred: {e:?}"),
    }
}
