Index · Getting Started

Testosterone keeps the history of your test runs and tells you what changed: what broke, what's flaky and what got slower. It does that for any runner that writes JUnit XML (or that it can run itself), as a pip install on a laptop or one container for a team, with no account and no per-seat bill. This page says where that fits next to the tools teams already know, and when one of them is the better choice.

Features and prices of the other tools change often. This page describes them as of October 2026, from their own docs; check theirs before you decide.

When to pick something else

• You want the richest report for a single run. Allure Report's per-run view (steps, retries, attachments) is deeper than Testosterone's. They work together: Testosterone can write Allure reports as one of its reporters and link to them from each run.
• You need test case management or manual testing. That's Allure TestOps, Testmo and similar tools. Testosterone only knows about tests that ran.
• You want failures sorted automatically, with ML, across a large organisation. ReportPortal's auto-analysis learns from past decisions. Testosterone remembers a cause someone marked and applies it to failures with the same message, which is simpler and easier to predict, but it doesn't guess.
• You run Playwright or Cypress at scale and want CI load balancing. Currents splits and orders specs across machines and streams results live. Testosterone records what ran; it doesn't schedule specs across CI machines.
• Your team already lives in Datadog. Datadog Test Optimization links tests to traces, deploys and test impact analysis. Testosterone has no equivalent.

When Testosterone fits

• Test data can't leave your network, or you don't want another SaaS and another per-seat bill.
• You use more than one runner (pytest, Playwright, Behave, a shell script) and want them in one history.
• You want "what changed since main" on every pull request without wiring up a hosted service: one CI step with the GitHub Action, or pytest --testo on your own machine.
• You want to try it in minutes: pip install testo-core, testo ingest results.xml, testo ui. The Getting Started guide has the details, and the live demo's try-it page reads a JUnit file in your browser with nothing installed.
