WireMock for Java and JVM languages

WireMock was originally created for Java development, and there are plenty of solutions when developing applications powered by the Java Virtual Machine.

WireMock #

WireMock, also known as WireMock Java is the flagman implementation of WireMock functionality and specifications, maintained on the WireMock GitHub organization. It is included into many distributions (including WireMock Docker), test framework adapters and products. Most of the documentation on this website is about WireMock Java, unless specified explicitly.

Usage:

• Running WireMock as a Standalone server
• Using WireMock in plain Java without frameworks

References:

• WireMock Java on GitHub

Integrations with test frameworks #

WireMock has integrations with many popular Java test frameworks for unit and integration testing.

• JUnit 5+ and Jupiter
• JUnit 4 and Vintage
• Testcontainers Java
• Spock - maintained outside WireMock’s organization on GitHub
