Detected code, here are some useful tools:

Formatted code 
package com.example;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders. * ;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers. * ;
import org.junit.jupiter.api.BeforeEach;
import org.junit.Test;
import org.springframework.test.context.junit.jupiter.web.SpringJUnitWebConfig;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

@SpringJUnitWebConfig(locations = "test-servlet-context.xml") class ExampleTests {
  MockMvc mockMvc;
  @BeforeEach
  void setup(WebApplicationContext wac) {
    this .mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
  }
  @Test
  public void testHomePage() throws Exception {
    mockMvc.perform(get("/AccessPoint")).andExpect(status().isOk()).andExpect(view().name("login"));
  }
}

<@&1004656351647117403> please have a look, thanks.

What does hover over mean? I guess you are in an IDE. Which one are you using?

#

You are not using Spring Boot?

Spring MVC: Failed to discover tests java.lang.NoClassDefFoundError: org.junit.jupiter.api.io.Cleanu

surreal canopy
#

the error you have in the title has nothing to do with not finding your tests

#

can you show the content of your pom.xml / gradle.build file? The full error would be nice too 😄

#

spring boot would solve this problem for you with its parent pom btw. cough cough ^^

#

I guess you messed up some of the junit dependencies and now you have conflicts

surreal canopy
#

aah I see... too bad 😦

surreal canopy
#

So, what's the full error? How did you define the junit dependencies in your pom.xml?

surreal canopy
#

let's start with all dependency definitions regarding JUnit; maybe it's enough ^^

shrewd daggerBOT
#

Detected code, here are some useful tools:

surreal canopy
#

I'm already seeing 2 different major versions for JUnit

#

4 and 5

#

you should choose one ^^

# 
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <version>5.11.1</version>
    <scope>test</scope>
</dependency>

Should be enough; I guess you can remove everything else ^^

shrewd daggerBOT
surreal canopy
#

ya; let's try 😄

#

yaps

surreal canopy
#

you are using the wrong annotation

#

this is the old JUnit 4 one

#

org.junit.jupiter.api.Test

#

I would recommend to do so, yes 😄

#

yap this here:

<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <version>5.11.1</version>
    <scope>test</scope>
</dependency>
surreal canopy
#

don't use this annotation; use org.junit.jupiter.api.Test

#

org.junit.Test is JUnit 4 ^^

#

replace the import and remove the JUnit 4 dependency from the pom

#

instead of import org.junit.Test; use import org.junit.jupiter.api.Test;

#

whoop whoop 😄

Detected code, here are some useful tools:

#

AFAIK; you can either define your bean config in a XML file or in a Java class via code

#

when you have it in an xml file use this location thingy

# 
@SpringJUnitWebConfig(ExampleTests.Config.class)
class ExampleTests {

    MockMvc mockMvc;

    @BeforeEach
    void setup(WebApplicationContext wac) {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
    }

    @Test
    public void testHomePage() throws Exception {
        mockMvc.perform(get("/AccessPoint"))
            .andExpect(status().isOk())
            .andExpect(view().name("login"));
    }
    
    @Configuration
    static class Config {
    }
}
surreal canopy
#

I would recommend Java classes and code 🙂

#

the xml way is very oldskool xD

surreal canopy
#

this is outdated ^^

#

also looks like Spring Boot is in use

#

nobody (tm) uses Spring without spring boot nowadays xD

#

too much pain to do everything by yourself

#

maintaining old crappy stuff too xD

#

Spring Boot also lowers complexity by a lot; and complexity is the biggest enemy of every dev :>

#

but ya; I guess you can't do much about it and have to life with it somehow :x

#

I'm not rly sure; as this is also mostly done by Spring Boot for you =/

#

I've never used this kind of config ^^

#

maybe you have to wire up all your beans in there? or just the ones which differ from the normal beans?

surreal canopy
surreal canopy
#

what's the error?

#

I guess you have @Controllers?

#

you have to configure these in the context

#

is my guess xD

#

your controllers maybe aren't loaded

#

yes

#

later you could extract this Config class into it's own file and share it with multiple tests when needed

surreal canopy
#

yes; but this is highly dangerous half knowledge from me ^^

#

maybe you can check other projects in your company how they did testing

#

this is spring boot xD

#

are you using Spring v 5.x.x?

#

because documentation there still uses JUnit 4 :x

#

maybe you have to fall back to JUnit 4 T_T

#

yap

#

remember to change the Test import annotation thingy again ^^

#

this wont work 😄

# 
<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.13</version>
  <scope>test</scope>
</dependency>
#

yes

#

xDD

#

seems so xDD

#

hmmm you won't get an example that easily out of it I guess

#

aaah darrn...

#

you will have a rly hard time without all the help of spring boot T_T

#

you need some rly old dude teaching you how vanilla spring works ^^

#

I initially started learning with pure spring like 15 years ago... but stuff was different 15 years ago xD

#

tell your boss; if they keep this stack... they will run out of developers able to maintain their code base ^^

#

without seeing the code base it's hard to tell anything xD

#

generally it will cost more money to maintain an old code base than rewriting / migrating it in the long run

#

banks for example have a lot of their code written in COBOL; nearly nobody knows how to write COBOL anymore; ppl get payed like 200k a year for writing this old crap ^^

#

finding and paying ppl knowing how Spring vanilla works isn't ez I would say :x

#

I work mostly remotely from home ^^

#

but I'm permanently employed and visit the office each wednesday

#

nope it's gotten worse xD

surreal canopy
#

nope I'm working with kubernetes in gcp ^^

surreal canopy
#

your only option is trial and error ^^

#

they use different annotations for their tests than you; but I'm also not sure what's the correct one for vanilla spring

#

you have to look through the spring source code and try to understand why things happening and what you have to do

#

when you are lucky there's some inline code docu o.o

#

I would demand a pay raise for doing this xD

surreal canopy
#

germany ^^

surreal canopy
#

you can try to add a @Configuration class with a component scan

# 
@Configuration
@ComponentScan(basePackages = {
    "your.package"
})
public class TestConfig {

}
#

maybe this will load the controllers :x

surreal canopy
#

the @ComponentScan will look for classes annotated with @Service, @Component, @Controller, @RestController, .... and load them as a bean

#

this will basically do the magic for you 😄

surreal canopy
#

yes

surreal canopy
#

can you @Autowire your controller into the test? is it null or is there an instance in it?

#

does the route match you defined in the controller?

surreal canopy
#

into the class ^^

shrewd daggerBOT
#

Detected code, here are some useful tools:

surreal canopy
#

the controller package isn't com.example :x

#

you have to scan the package where your code lives ^^

#

and your test packages should reflect your production code packages

#

don't call them com.example when it is com.<organisation-name> ^^

#

how green are you actually? don't get me wrong; but you seem to be very junior; and you should definitely have a senior dev supporting you o.o

#

don't let them exploit you, because you are cheaper than a senior dev or smth xD

#

"green horn" is a common phrase I guess for somebody new ^^

#

yes ^^

#

I'm worried that you are being exploited for cheap money T_T

#

but you did code in Java before?

#

aaaah

#

than this is a very hard task T_T

#

sure 😄
