Isolated Controller Test can't instantiate Pageable
Original answer:
The problem with pageable can be solved by providing a custom argument handler. If this is set you will run in a ViewResolver Exception (loop). To avoid this you have to set a ViewResolver (an anonymous JSON ViewResolver class for example).
mockMvc = MockMvcBuilders.standaloneSetup(controller)
.setCustomArgumentResolvers(new PageableHandlerMethodArgumentResolver())
.setViewResolvers(new ViewResolver() {
@Override
public View resolveViewName(String viewName, Locale locale) throws Exception {
return new MappingJackson2JsonView();
}
})
.build();
Updated (2020):
It is not necessary to add the ViewResolver
anymore.
Regarding the parallel answer:
It does not solve the problem for the original question to have this test running without ApplicationContext
and/or friends.
Just add @EnableSpringDataWebSupport for test. Thats it.
For spring boot simply adding the ArgumentResolvers solved for me:
From code which triggered the error:
this.mockMvc = MockMvcBuilders.standaloneSetup(weightGoalResource).build();
To this, which works:
this.mockMvc = MockMvcBuilders.standaloneSetup(weightGoalResource)
.setCustomArgumentResolvers(new PageableHandlerMethodArgumentResolver())
.build();
