Citrus vs SoapUI

Citrus is a free integration-test framework for messaging applications and microservices. It can make a test act as both client and server across messaging interfaces, send and sequence messages, and validate payloads and other elements. Supported endpoints include HTTP, Kafka, JMS, Apache Camel, mail, FTP/SFTP, OpenAPI, SOAP, Docker, Kubernetes, Knative, SQL, and SSH. Validation covers JSON and XML, XML schemas, DTDs, and database data. Test cases can use loops, delays, retries, parallel sections, and timeouts. Tests are written in Java, XML, YAML, or Cucumber BDD features. Citrus integrates with JUnit 5, Cucumber, JBang, Quarkus, Spring Boot, TestNG, and JUnit 4, with Maven and Gradle setup guidance. It runs on Linux and requires Java 17 or newer since version 4.0. Citrus is Apache-licensed freeware for testing commercial applications.

SoapUI is an open-source tool for testing REST, SOAP, and GraphQL web services. It supports drag-and-drop creation of functional and regression tests, assertions, and data-driven tests, and can create service mocks from WSDL. The listed protocols also include JMS and SOAP/WSDL. Functional tests can be extended into load testing, including runs from command-line tools. Named automation integrations include Maven, Hudson, Bamboo, JUnit, and Ant, and SoapUI can run from other CI tools. It can configure incoming and outgoing WS-Security, including encryption, signatures, SAML, keystores, and truststores. SoapUI is described as cross-platform for Windows, Mac, and Linux/Unix. The open-source edition is listed for basic functional and performance testing; security testing appears among expanded capabilities associated with ReadyAPI. The listed SoapUI Open Source plan is free and includes API testing, mocking, and command-line automation. SmartBear describes it as a starting point for developers and testers, with support and a community forum linked on the site.
