Built for end-to-end testing of your entire back-end

Create comprehensive end-to-end tests that validate the entire workflow of your APIs from an API definition or live endpoints. Pass response data and add assertions with just a few clicks - no coding required.

Synthetically generate or provision data

Boost test coverage with easy data-driven testing. Create synthetic data like addresses, social security numbers, and more on the fly or import data from a file, like a CSV or TXT file, or database, like MySql or Postgres.

Flexible automated execution options

Integrate SoapUI directly into the tools you already love such as Git, Jenkins, TeamCity, and Azure DevOps or utilize TestEngine for centralized executions, parallel test runs and job queuing.
Ease of Creation Create tests and assertions with just a few clicks. Start by importing an API definiton, hitting an endpoint, or discovering an API through our built-in browser. Learn More
End-To-End Testing Testing the outcome of a multi-step API transaction? ReadyAPI supports testing of REST, JSON, XML, SOAP, JDBC, JMS, and other protocols in a single test case. Learn More
Mobile Testing Drive continous quality of your web-service with native support of Docker, Jenkins, TeamCity, Azure DevOps, and other tools through plugins or our command-line utility. Learn More

Fit API testing into your continuous delivery pipeline

ReadyAPI makes it easy to fit test automation right into your DevOps or Agile development workflow. With integrations up and down the pipeline, you can store your test cases in a Git repo, commit new code, and have your CI server run those stored tests during every build on nearly any environment - Docker included.

  • Native Integrations with Jenkins, Azure DevOps, and TeamCity 
  • Command-line support for automated testing on nearly any CI server
  • Results can be exported in common formats like jUnit or XML

Instantly build assertions against critical API endpoints

Use artificial intelligence to drive bulk validation of your entire APIs payload in just a few seconds. Make sure that your API does what it is supposed to do and returns the data it's expected to return without creating assertions on a one-off basis. With ReadyAPI, you can: 

  • Import API descriptions like Swagger, OAS 3.0 and others to rapidly build out API test templates 
  • Record live traffic or hit the endpoint a few times to train our model on your APIs response
  • Create a Smart Assertion against the APIs response - giving you maximum test coverage

Put dynamic data to work for you

Using realistic, dynamic data in your functional API tests is critical to covering boundary conditions, positive/negative testing, and truly simulating the way your consumers interact with your APIs in the real world. 

  • Import data from external files or databases
  • Create synthetic data like addresses and phone numbers
  • Share data sets across functional, load, and security tests

Harden your API with security scans during every deployment

ReadyAPI enables you to add security scans to your new or existing functional tests with just a click. You can run cross-site-scripts, fuzzing scans, SQL injections and more against your endpoints,  ensuring critical API security testing occurs every time you deploy.

  • Protect your APIs by running scans designed to mimic hacking techniques
  • Create custom scans or layer them over existing scans to cater to your own use case
  • Integrate API security with automation to ensure your APIs stay secure after every code change
