I have added spring-cloud-starter-aws-parameter-store-config dependency as explained in the spring documentation. Now, for unit tests I want to disable parameter store configuration. But not able to do it.
I tried setting following property in test/application.properties
aws.paramstore.enabled=false
Also tried excluding AwsParamStoreBootstrapConfiguration.class from AutoConfiguration but still not working.
Exception

I was able to figure out the solution. Seems that SpringBootTest tries to load ssmClient even before the test configuration class, and before loading application.properties. The solution is to disable paramstore by specifying the property on @SpringBootTest itself
@SpringBootTest(classes = MyApp.class, properties = {"aws.paramstore.enabled=false"})
Edit:
I was able to disable paramstore with alternative approach by adding the property (aws.paramstore.enabled=false) to bootstrap.properties file. This one is much simpler solution
