Tests fail for GCP Http Function - Message: Binder registry is not mutable
I wrote a test for the example GCP http function and it failed by throwing exception:
io.micronaut.context.exceptions.BeanInstantiationException at DefaultBeanContext.java:1915 Caused by: java.lang.UnsupportedOperationException at ArgumentBinderRegistry.java:38
If I remove the @MicronautTest annotation, the test passes.
Task List
- [x] Steps to reproduce provided
- [x] Stacktrace (if present) provided

Steps to Reproduce
- Set up this example:
https://github.com/micronaut-projects/micronaut-gcp/tree/master/examples/hello-world-cloud-function - Write a micronaut test with @MicronautTest annotation.
- Run the test.
- It fails

Hey, I was able to solve this.
In build.gradle if I remove
test.classpath += configurations.developmentOnly
It works.
I did not dig in much however.
Workaround only works when we are not using @Inject or any bean instantiation while writing the tests.
On Digging further, I found out that NettyBinderResgistrar's onCreated method is trying to add ArgumentBinders to the registry. However, the registry is instantiated as GoogleBinderRegistry, which does not have addRequestArgumentBinder operation implemented and hence, throws an exception.
@Override
public RequestBinderRegistry onCreated(BeanCreatedEvent<RequestBinderRegistry> event) {
RequestBinderRegistry registry = event.getBean(); //It is of type GoogleBinderRegistry.class
registry.addRequestArgumentBinder(
new BasicAuthArgumentBinder()
);
....
}
Leaving this here for posterity in case this helps someone else in the future. One way to get "Binder registry is not mutable" exception is to have a mix of runtimes in your Micronaut service. In other words if you specified as your runtime something like tomcat or undertow i.e.
micronaut { runtime("undertow")
but somehow you declared dependency on another service which has a runtime of 'netty'. Micronaut will try to start netty with scaffolding from Servlet engine and you will get weirdness like this. I.e. take a look at your classpath and how your microservice was built.
