SpringBootTest and MockMvc creating an enormous amount of console logging - how to disable?

Question

We're using @SpringBootTest with an @Autowired private MockMvc mockMvc attribute to mock HTTP requests to our controller classes.

For some reason that we can't seem to determine, this is creating enormous amounts of logging for each test case, and is filling our logs with thousands of lines of text that looks like:

All of my internet searching and Spring Boot Test documentation reading has been fruitless. Where is this logging coming from, and how can we turn it off?

We've scanned our code exhaustively, and are confident that we're not printing/responsible for it.

Answer 1

This is coming from MockMvc.

It would appear that you may have overridden the default and instructed Spring Boot to always print the debug output for MockMvc.

You should be able to deactivate this by declaring @AutoConfigureMockMvc(printOnlyOnFailure = true) or by omitting the printOnlyOnFailure flag since true is the default value.

You configure the output mode via the print attribute -- for example, @AutoConfigureMockMvc(print = MockMvcPrint.NONE).

Answer 2

You have to disable info logger from spring framework package in application.properties. Add the below property in application.properties.

logging.level.org.springframework=OFF
