Wilma

Service Virtualization Solution – a combined Service Stub and Transparent Proxy.

Wilma is a Service Virtualization tool, that combines the capabilities of a Service Stub and a HTTP/HTTPS Transparent Proxy. Its main purpose is to support development and testing applications/services/components those functionality relies/depends on another application/services/components that can be owned by you or can be owned by 3rd party as well. The selected architecture approach makes it capable to use it in unit, integration, functional, end-to-end, performance test environments and environments those contains microservices. It can be used for manual tests too. It is expandable easily via plugins and configurable on-the-fly. It is written in Java, and the solution consists of two standalone applications:
  • Wilma application is the highly configurable Service Virtualization tool
  • Wilma Message Search application (optional component) provides high performance searching capability of the request-response pairs that were logged by Wilma application.

Quick intro for end users

Wilma application

Requirements

  • JRE 8 (pls use earlier Wilma releases than V1.6.x when you need to use Java 7 version)
  • The latest release of Wilma application downloaded and extracted into a folder.

Configuring Components/Services to use Wilma

The most simple way to do this is by configuring the Component/Service to use Wilma as HTTP(S) proxy. In case of Java components/services, this can be done by adding a few VM arguments to the run configuration:
JAVA_PROXY_FLAGS=-Dhttp.proxyHost=[wilma-url] -Dhttp.proxyPort=[wilma-proxy-port] -Dhttps.proxyHost=[wilma-url] -Dhttps.proxyPort=[wilma-proxy-port]
java ${JAVA_PROXY_FLAGS} ...

Configure and run Wilma

To run Wilma with simplest configuration, just download the release, extract it and run: java -jar wilma-x.y.z.jar wilma.conf.properties
See this page for more detailed information on how to configure Wilma, and Component/Service that uses Wilma.

Wilma - a combined Universal Stub and Transparent Proxy

Wilma is a Service Virtualization tool, that combines the capabilities of a Service Stub and a HTTP/HTTPS Transparent Proxy. Its main purpose is to support development and testing applications/services/components those functionality relies/depends on another - usually 3rd party - service or services. The selected architecture approach makes it capable to use it in performance test environment and environment that contains microservices. It is written in Java, and the solution consists of two standalone applications:
  • Wilma application
  • Wilma Message Search application
Wilma application is the highly configurable Service Virtualization tool. It logs the messages, and meanwhile acts as a proxy between the components, makes it possible to stub responses based on configuration defined in XML file(s). It is also possible to alter/modify the messages, real-time. It is designed for use in development and test environments where test automation is in use (unit, integration, functional or end-to-end). Also can be used for manual tests. It is expandable easily via plugins.
Wilma Message Search application provides high performance searching of the request-response pairs those were logged by Wilma application.
