Tests

Tests is where opportunities become real experiments. Each test has its own detail page with setup, content (variant code), and analytics.

Test status

The Tests page is a kanban board. Tests move through these statuses:

• Idea — the opportunity has been promoted to a test, but no variant has been generated yet.
• Generating — Spar is producing the variant code in the background.
• Draft — variant is generated and being edited.
• Ready — variant is finalized and ready to deploy.
• Running — live on the store, accumulating traffic.
• Paused — temporarily stopped (allocation is frozen but the test isn't finished).
• Completed — finished, with a result attached.
• Cancelled — abandoned before completing.
• Failed — something went wrong (deploy error, missing tracking, etc.).

Drag a card between lanes to update its status.

The three tabs on a test

• Setup — audience, allocation, hypothesis, metric.
• Content — the variant code (HTML, CSS, JS) and any content changes.
• Analytics — sample size, conversion deltas, and statistical significance over time.

How Spar decides when a test is "done"

Spar uses sequential statistical testing. It monitors significance continuously and flags a winner at 95% confidence — you don't need to pick a fixed duration upfront. A test can also be ended manually any time.

Where tests run

Spar can deploy tests through a few channels depending on what you've connected:

• Shopify (theme app extension) — for Shopify stores.
• GrowthBook — for teams already standardized on GrowthBook.
• Intelligems — for teams using Intelligems for pricing tests.

Configure your default execution target under Settings → Tests.

Orphan suggestions

If you have running experiments on your platform (e.g. GrowthBook) that don't have a matching opportunity in Spar, the Tests page will surface them as orphan suggestions so you can wire them up.
