Crate viewpoint_test 

Test framework for Viewpoint browser automation.

This crate provides the primary testing API via TestHarness, along with assertions and configuration for browser-based E2E tests.

Primary API: TestHarness

The TestHarness provides explicit test setup with browser, context, and page access. Cleanup happens automatically via Drop.

use viewpoint_test::TestHarness;

#[tokio::test]
async fn my_test() -> Result<(), Box<dyn std::error::Error>> {
    let harness = TestHarness::new().await?;
    let page = harness.page();

    page.goto("https://example.com").goto().await?;

    Ok(()) // harness drops and cleans up
}

Fixture Scoping

The harness supports different scoping levels:

• TestHarness::new() - Test-scoped: new browser per test (default)
• TestHarness::from_browser() - Module-scoped: reuse browser, fresh context/page
• TestHarness::from_context() - Shared context: reuse context, fresh page only
