# Install the Test Propeller CLI curl -fsSL https://testpropeller.com/install.sh | sh

# Give it a whirl on one of our demo agents

# Run a pre-warmed Elasticsearch container CONTAINER=$(tp run --mem 4g --wait-http :9200/health --lifetime 30s elasticsearch:9.3.0)

# Expose the Elasticsearch API on an unused port PORT=$(tp expose $CONTAINER 9200)

# Use Elasticsearch as part of your test curl "http://localhost:$PORT"

A message from the Founder

Testing is broken.
External dependencies force you to compromise:

Mocks and stubs are easy to start with. But they drift from reality and give you a false sense of security.
Shared environments are realistic. But tests trip over each other due to shared state and you need to maintain brittle clean up scripts.
Starting Testcontainers for every test is realistic and isolated. But it's painfully slow, clogs up your CI pipeline, and breaks your train of thought.

I saw the status quo as a tooling failure.

That's why I built Test Propeller.

Pre-warming containers eliminates the lengthy startup time.
You get realistic tests, isolated runs, and fast feedback.

Frequently Asked Questions

Are there any limits?
Do I need to configure access to an OCI registry?
What happens when my credits run out?: You'll no longer be able to run pre-warmed containers. Existing containers will continue to work as normal. Test Propeller credits are prepaid, so you won't incur overage fees leading to suprise bills.
How do I ensure I don't run out of credits?: Subscribe to a plan that has enough included monthly credits for your typical usage. Buy top-up credits in advance to cover for months with abnormally high usage. Keep an eye on your remaining credits in the Test Propeller dashboard or with the tp credit ls CLI command. You'll be notified by email when your credits are running low.
What payment methods do you accept?: We accept credit cards, debit cards, digital wallets, bank redirects, and bank transfers. Prices are in USD and you'll be billed in your local currency.
What's the refund policy?: Refunds are available within 30 days of purchase. A full refund may be granted if none of the credits have been used. A partial refund may be granted if a small portion of the credits have been used, at our discretion. Contact us to discuss refund options.
