java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration with your test

Question

Should we make seprate test folder or test folder under src?

My test class location is: server/test/com/cellpointmombile/mconsole/manualtrigger/ManualTriggerControllerTest.java

And I am writing Junit for class ManualTriggerController, and its path is :server/src/main/java/com/cellpointmobile/mconsole/controller/ManualTriggerController.java

My main class, i.e Application.java is in below location: server/src/main/java/com/cellpointmobile/mconsole/app/Application.java

Can you please tell what am I doing wrong?

Welcome to Stack Overflow! Other users marked your question for low quality and need for improvement. I re-worded/formatted your input to make it easier to read/understand.

The information where some of your classes sit doesn't help here much. It could also be some content of your test code. My suggestion: don't try to do such things "trial and error". Go, read and practice using a tutorial that gives you all required steps to unit test a spring boot app. Understand how these things work, and then try to use them in your own project. — GhostCat

Follow the packages have used, test is running successfully.

Inside src/main/java

package com.an.csv.mvc;

import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController("/myclass")
public class TestControllerEx {

 @GetMapping
  public ResponseEntity control(){
    return new ResponseEntity("success",HttpStatus.OK);
  }
}

Spring Boot main class:

package com.an.csv;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.data.jpa.JpaRepositoriesAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, JpaRepositoriesAutoConfiguration.class})
public class CSVBatchApplication {

  public static void main(String[] args) {
    SpringApplication.run(CSVBatchApplication.class, args);
  }
}

Under src/test/java

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;

import com.an.csv.CSVBatchApplication;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

@RunWith(SpringRunner.class)
@SpringBootTest(classes = CSVBatchApplication.class)
@AutoConfigureMockMvc
public class ControllerIntegrationTest {

  @Autowired private MockMvc mockMvc;

  @Test
  public void testController() throws Exception {
    mockMvc
        .perform(get("/myclass"))
        .andExpect(status().isOk());
  }
}

Tried it, but facing below issue : {Caught exception while allowing TestExecutionListener [org.springframework.boot.test.autoconfigure.SpringBootDependencyInjectionTestExecutionListener@25af5db5] to prepare test instance [com.cellpointmobile.promotion.test.PromotionTest@14bae047] - @ConditionalOnClass did not find required classes 'javax.jms.ConnectionFactory', 'org.apache.activemq.artemis.jms.client.ActiveMQConnectionFactory' (OnClassCondition)}

As you say, My test class location is : server/test/com/cellpointmombile/mconsole/manualtrigger/ManualTriggerControllerTest.java

it should be, server/src/test/com/cellpointmombile/mconsole/manualtrigger/ManualTriggerControllerTest.java

Also make sure your test class ManualTriggerControllerTest has been annoted with @SpringBootTest or you can also use @ContextConfiguration but @SpringBootTest is simpler because you need not worry about anything else as it takes care of context loading, configuration for your tests to run.

Your ManualTriggerControllerTest should look like below,

@RunWith(SpringRunner.class)
@SpringBootTest
public class ManualTriggerControllerTest{
/* your code */
}

I hope this helps !
