My tests in Spring project work well until I did something and in my WebMvcTest, MockMvc started simply to be null. In Service tests where I need to mock my repository this exception is thrown:

Need to check your dependencies, if this mockito-all is including in the test resources.
I recommend to add the mockito-core dependency ().
<dependency>
<groupId>org.mockito</groupId>
<artifactId>mockito-core</artifactId>
<version>3.7.0</version>
<scope>test</scope>
</dependency>
The mockito-all dependency mentioned in another answer was last updated in 2015.
