chrome-for-testing-manager

Programmatic management of chrome-for-testing installations.

• Automatically resolves the configured Chrome for Testing version.
• Automatically downloads chrome-for-testing chrome and chromedriver binaries into a local cache directory.
• Possibility to spawn the chromedriver process using a random port.
• Optional line-based listener for chromedriver stdout/stderr during a run.
• Built-int session management.

Frees you from the need to

• manually download a chromedriver package matching your locally installed chrome,
• starting and stopping it manually,
• hardcoding the chosen chromedriver port into your tests and
• doing this all-over when trying to test with a new version of chrome.

Installation

[dependencies]
chrome-for-testing-manager = "0.9"
rootcause = "0.12"
thirtyfour = "0.36"

# Additional dependencies for the example below.
assertr = "0.5"
tokio = { version = "1", features = ["full"] }

Example

use assertr::prelude::*;
use chrome_for_testing_manager::{Chromedriver, ChromedriverRunConfig};
use rootcause::Report;
use std::time::Duration;
use thirtyfour::prelude::*;

// This library requires being used in a multithreaded runtime.
// If you want to run a test, use: `#[tokio::test(flavor = "multi_thread")]`.
#[tokio::main]
async fn main() -> Result<(), Report> {
    Chromedriver::run(ChromedriverRunConfig::default())
        .await?
        .with_session(async |session| {
            session.goto("https://wikipedia.org").await?;

            let search_form = session.find(By::Id("search-form")).await?;
            let search_input = search_form.find(By::Id("searchInput")).await?;
            search_input.send_keys("selenium").await?;

            let submit_btn = search_form.find(By::Css("button[type='submit']")).await?;
            submit_btn.click().await?;

            // Look for header to implicitly wait for the page to load.
            let _heading = session
                .query(By::Id("firstHeading"))
                .wait(Duration::from_secs(2), Duration::from_millis(100))
                .exists()
                .await?;
            assert_that!(session.title().await?).is_equal_to("Selenium – Wikipedia");

            Ok(())
        }).await
}

Managed sessions opt-out

The with_session function. providing a thirtyfour session, called in the example, was only available because chrome-for-testing-manager enables its thirtyfour feature by default.

If you just want it's chrome/chromedriver version resolution, download and launch orchestration, declare the dependency as

chrome-for-testing-manager = { version = "0.9", default-features = false }

instead.
