Attribute Macro fixture 

#[fixture]

#[fixture] — register a custom, dependency-injected, scoped fixture.

The function takes a single TestContext and returns ferridriver_test::Result<T>. The resolved value is shared as Arc<T> and retrieved from a test (or another fixture) via ctx.get::<T>("fixture_name").await?. Custom fixtures may depend on the built-ins (page, context, browser, request, test_info) and on each other — dependencies resolve lazily through ctx.get.

use ferridriver_test::prelude::*;
use std::sync::Arc;

#[fixture(scope = "test")]
async fn authed_page(ctx: TestContext) -> ferridriver_test::Result<Arc<Page>> {
    let page = ctx.page().await?;
    page.goto("https://app.example.com/login", None).await?;
    page.locator("#email", None).fill("user@example.com", None).await?;
    page.locator("button[type=submit]", None).click(None).await?;
    Ok(page)
}

#[ferritest]
async fn shows_dashboard(ctx: TestContext) {
    let page = ctx.get::<Arc<Page>>("authed_page").await?;
    expect(&page.locator("h1", None)).to_have_text("Dashboard").await?;
}
