This article covers the unit testing of a SpringBoot Camel Route using Junit.
Let us consider the use case of a process that moves the file from the input directory to the output directory by polling at specific timer intervals.
The route configurations are externalized and maintained in the application.yml file.
On successful run, notice that the file is deleted from the input directory of the dev folder and copied to the output directory as per the configuration.
Rather than checking manually if the file is copied to the output directory, a more ideal approach to test is by writing Junit test cases.
Add the below dependency to the pom.xml:
ProducerTemplateobject is used to produce the files and place in the input directory.
@ActiveProfilesannotation can be used to activate the spring profiles. In the below example, we will use dev profile.
@SpringBootTestannotation, Spring Boot provides a convenient way to start up an application context to be used in a test.
SpringRunnerprovides support for loading a Spring
ApplicationContextand having beans
@Autowiredinto your test instance
In the below example, we create the input file in the input directory and at the end of test execution, we check if the file is successfully moved to output directory:
Run the test and observe the successful execution of the test case.
Notice that the file is deleted from the input directory and copied to the output directory on successful execution.
