Test java.lang.IllegalStateException: Failed to load ApplicationContext

Question

I try to write a simple tests for my project(it is my first test, so don't judge me harshly), but my test failed and I get an error:

Applicationtest.properties:

spring.datasource.url=jdbc:mysql://localhost:3306/fruitshop?serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=password
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
[email protected]@
spring.main.web-application-type=none

I write a tests for two controllers. My Tests:

import com.Products.Products;
import org.junit.Assert.*;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.web.client.TestRestTemplate;
import org.springframework.boot.web.server.LocalServerPort;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.ResponseEntity;
import org.springframework.test.context.junit4.SpringRunner;
import static org.junit.Assert.assertNotNull;

@RunWith(SpringRunner.class)
@SpringBootTest(classes = ApplicationTest.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)

public class ProductsControllerTest {

    @Autowired
    private TestRestTemplate restTemplate;

    @Test
    public void addNewProduct() {
        Products product = new Products();
        product.setName("Orange");
        product.setPrice(121);
        ResponseEntity<Products> postResponse = restTemplate.postForEntity("/products/addProduct", product, Products.class);
        assertNotNull(postResponse);
        assertNotNull(postResponse.getBody());
    }

    @Test
    public void getAllProducts() {
        HttpHeaders httpHeaders = new HttpHeaders();
        HttpEntity<String> entity = new HttpEntity<String>(null, httpHeaders);
        ResponseEntity<String> response = restTemplate.exchange("/products/allProducts",
                HttpMethod.GET, entity, String.class);
        assertNotNull(response.getBody());
    }
}

This is my controller I use mysql:

package com.Products;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;

@Controller
@RequestMapping(path = "/products")
public class ProductsController {

    @Autowired
    private ProductsRepository productsRepository;

    @RequestMapping(value = "/addProduct", method = RequestMethod.POST)
    public @ResponseBody String addNewProduct (@RequestParam (value = "name")  String NameOfFruit,
                                               @RequestParam  (value = "price") int PriceOfProduct) {
        Products product = new Products();
        product.setName(NameOfFruit);
        product.setPrice(PriceOfProduct);

        productsRepository.save(product);
        return "Done";
    }

    @RequestMapping(value = "/allProducts", method = RequestMethod.GET)
    public @ResponseBody Iterable<Products> getAllProducts() {
        return productsRepository.findAll();
    }
}

ApplicationTest:

package com.Products;

import org.junit.Test;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
public class ApplicationTest {
}

I don 't know what to do anymore. Please indicate what the problem is and how I can solve it

Worked version: https://github.com/Asel06/Neobis-Tasks/tree/master/task-9/Week9

Solution

Remove class=ApplicationTest.class because of this your @SpringBootTest doesn't scan for other @Configuration classes

The component classes to use for loading an ApplicationContext. Can also be specified using @ContextConfiguration(classes=...). If no explicit classes are defined the test will look for nested @Configuration classes, before falling back to a @SpringBootConfiguration search.

[GeertPt]

Can you show your ApplicationTest as well? And indicate which version of Spring Boot you are using? EntityManagerFactory is a JPA interface. It's usually auto-configured by spring boot, but you're probably missing some annotation or something similar in ApplicationTest.

[M. Deinum]

1. Your dependencies are a mess, 2. delete ApplicationTest and just add a clean @SpringBootTest to your testclass.

[Nonika]

@Asel what do you use jetty,jboss,tomcat or what? also do you use jsp or what

[Nonika]

Because you have everything into your pom.xml

[Nonika]

Is there specific reason that you need embeded jetty enstead of tomcat?

[Asel]

@Nonika No reason. It's just that when I was writing the test I started making mistakes and to fix them I started googling and doing everything that i met

[Nonika]

So embedded tomcat is ok for you?

[Nonika]

Also are you using jsp?

[Asel]

@Nonika Tomcat is ok, for the test I need to connect to my database and test the api so if it is better to use other tools for this, so it's ok

[Nonika]

You should correct your pom.xml there are duplicated dependencies and lots of unneeded ones you can start from start.spring.io to generate correct project

[Asel]

@Nonika I did all what i can and what is happened

[Nonika]

@Asel can you be more specific. what is your current situation

[Asel]

@Nonika I made some changes (add .properties for test, you can see changes in my question ) and after this i have the error: ``` org.springframework.web.client.ResourceAccessException: I/O error on POST request for "localhost:8080/products/addProduct": Connection refused: connect; nested exception is java.net.ConnectException: Connection refused: connect``` How i can change the port ? Or fix this problem

[Nonika]

can you upload your project on github?

[Asel]

@Nonika Yep Github

[Nonika]

@Asel I have added pullrequest

[Asel]

You mean @ContextConfiguration(classes = ApplicationTest.class) If you mean this, it's doesn't work

[Nonika]

can you post your build.gradle or pom.xml?

[Nonika]

and post also ApplicationTest.class

[Nonika]

@Asel See pull request

[Asel]

I adore you! Seriously.

[Nonika]

:-) :-) :-) :-)

[hanbin615]

@Asel what happened in the pull request?
