In this article I will, using a test-case, show how to publish and consume MQTT messages using the reactive HiveMQ client library. I will use the Mosquitto MQTT broker for the test. The example application will be implemented using Spring Boot 3 and Java 17. The example will initially allow unauthenticated access that later will… Read More »
These are a few short notes on how to log requests received by a WireMock server as well as any mock response generated in connection to a request. I have found this to come in handy when having multiple mappings loaded into WireMock and an incorrect mapping being chosen in the test.In addition, I will… Read More »
In this second article on HTTP testing with WireMock and REST Assured I will show how to set up a HTTPS mock service, with and without mutual authentication, using WireMock and then use REST Assured as a HTTP client to send requests to the service. I highly recommend reading the first article if you haven’t… Read More »
I have been busy as of lately but feel that I really should squeeze in an article on mocking HTTP services after having found another nice tool that has been on my wishlist for some time. In this first article I will show some examples of using WireMock that are of particular use to me.… Read More »
In this post I will show how to run an embedded instance of ActiveMQ that uses SSL for communication. In the process I will also show how to configure a JMS client to use SSL. The resulting project is available on GitHub. I have omitted the keystore and truststore in this article – if you… Read More »
In this post I will show a workaround for a bug that appears when testing Mule flows that contains one or more validators from the relatively new Validations Module. The bug has been verified to be present in both Mule ESB 3.7.0 and 3.8.0. There are two issues in MuleSofts JIRA here and here, but the fix… Read More »
In this article I will show how to accomplish dependency injection of fields in tests that inherit from the Mule class FunctionalTestCase; both of dependencies to Spring beans and of values from property files. Background On an earlier occasion, I have attempted to use the standard @RunWith(SpringJUnit4ClassRunner.class) annotation in order to be able to have Spring… Read More »
The other day I ran into a problem that made me quite puzzled. I was working on a project which build and ran without any problems. Then I enabled the use of a third-party library during the execution of the tests in the project and suddenly there were out of memory errors in PermGen during… Read More »
In this post I will show how an embedded ActiveMQ broker is automatically started when using the broker URL “vm://localhost” in a Mule JMS connector, without any additional configuration, and how to disable this behaviour. I will also look at how to explicitly configure an embedded ActiveMQ broker in a Mule configuration file. As documented… Read More »
My very first blog post described how to unit test Mule transformers that access session and/or invocation scoped message properties. To accomplish that I developed a new, better, Mule message. In this post I will describe how this new Mule message class can be extended to allow for session and/or invocation scoped message properties to… Read More »
