java.lang.IllegalArgumentException: A ServletContext is required to configure default servlet handling
One of your @Configuration
classes is obviously annotated with @EnableWebMvc
. That's how DelegatingWebMvcConfiguration
ends up in your stack trace, since it is imported by @EnableWebMvc
.
So although you think you don't need a WebApplicationContext
(and hence a ServletContext
), you in fact do need it simply because you are loading an application context with @EnableWebMvc
.
You have two options:
- Compose the configuration classes for your integration test so that you are not including the web-related configuration (i.e., the
@Configuration
class(es) annotated with@EnableWebMvc
). - Annotate your test class with
@WebAppConfiguration
as suggested in other comments above.

It seems like you are missing
@WebAppConfiguration
from your test class.
The documentation states
The resource base path is used behind the scenes to create a MockServletContext which serves as the ServletContext for the test’s WebApplicationContext.
Typically a Servlet container would provide the ServletContext
. Since you are in a testing environment, you need a fake. @WebAppConfiguration
provides that.
For you to instantiate the Servlet context, you would have to use the annotation.
@WebAppConfiguration
A class-level annotation that is used to declare that the ApplicationContext loaded for an integration test should be a WebApplicationContext. The mere presence of @WebAppConfiguration on a test class ensures that a WebApplicationContext will be loaded for the test, using the default value of "file:src/main/webapp" for the path to the root of the web application (i.e., the resource base path). The resource base path is used behind the scenes to create a MockServletContext which serves as the ServletContext for the test’s WebApplicationContext.
