Use two of the most popular tools in the market

Bring your Postman collection or MochaJS automation test, then upload it or link it to the Testable platform. There is no conversion layer and no special requirements.

Test runners in the Testable VPC, your VPC, and your data center across AWS, Azure, and Google Cloud

Your infrastructure or ours

The VMs that execute your test can be automatically spun up in our cloud networks or your own with support for AWS, Azure, Google Cloud, or self-hosted. Link your cloud accounts so that Testable can automatically spin up the VMs for your tests in your virtual networks. Or use our flexible test runner container to run the tests on your own infrastructure.

Run your API test as a load test

Reuse your API tests for load testing without making any changes. Create a new test configuration with the desired load profile, and Testable handles spinning up all the virtual users and test runner instances. Scales up to millions of virtual users.

CodePipeline with source, build, Testable API test, and production stages and a success rate gauge

Continuous API testing automation

Testable makes it simple to integrate and automate API testing in your continuous integration or continuous delivery pipeline once you define success criteria for your tests.

  • Use the simple Testable API to automate your testing.
  • Schedule tests with the visual test scheduler.

See why an API workflow failed

Compare trends, detect anomalies, and inspect request-level traces so your team can move from a failed assertion to the cause.

  • Trend analysis

    As you run a test multiple times, Testable shows trends for every single metric, so you instantly see how this run compares to past runs.

  • Anomaly detection

    Building on trend analysis, Testable detects anomalies and can automatically mark the test as a failure.

  • API traces

    See the full details for every API request: full URL, all metrics, status, request headers and body, and response headers and body. Traces work for streaming APIs such as WebSockets, not only HTTP.

Easy to bring your tests to Testable

Bringing your Postman or MochaJS tests to Testable is simple and requires no special changes to make them work.

  • Create in the browser. Create and edit your MochaJS tests visually on the Testable website.
  • Postman collection URL. If you have a URL for your Postman collection, configure it on Testable and the latest copy is used every time your test runs.
  • Upload. Upload the Mocha test or Postman collection to Testable.
  • Git link. Connect your test to the Git repository that holds everything needed to run it. Every time the test runs, each test runner pulls the latest code. This works even when your Git repository is behind a firewall, as long as the test runners are on the same network.

Fixed IP addresses for applications that allowlist clients

For applications that need to allowlist client IP addresses, choose a specific set of elastic IPs, or let Testable assign any IP that is available.

  • Bring your own

    For tests that run inside your VPC, use your own account's elastic IPs.

  • Use ours

    For tests that run inside Testable's VPC, Testable allocates a set of elastic IPs to your account.
