Camel Spring Boot Integration Tests

The camel-itest-spring-boot module provides an integration testing framework for camel components, to check their compatibility with spring-boot.

Each test-case defined in src/test/java/org/apache/camel/itest/springboot executes the following steps:

• Creates a spring-boot jar by putting the spring-boot loader, some utility classes in the main jar, and all other libraries (including the camel component under test) as nested jars;

  • Launches a new JVM including the spring-boot jar and test classes in the classpath, then starts the spring-boot platform;

  • Executes a list of predefined checks in the spring-boot environment to verify that the component has been created correctly: checks that the camel context has been created, that the camel components can be activated (including data format and languages).

Additional options

Test options can be changed from the configuration of the maven-surefire-plugin in the pom.xml file.

Some useful options include:

• itest.springboot.includeTestDependencies (default=true): when this option is enabled, the integration test will locate the module pom.xml file and include in the spring-boot jar also the test-scoped dependencies of the module. The inclusion of other libraries often activates some hidden behaviour of spring-boot.

• itest.springboot.unitTestEnabled (default=false): when this option is enabled, the integration test will locate the test-classes of the module and run the unit tests after the execution of the usual checks. Note: a full build of each component is required prior to running the unit tests. Test dependencies are implicitly included.

Note: logging dependencies (eg. log4j) are fixed automatically, to prevent conflict with spring-boot logging system.
