How to use prettifyFailure method of org.mockito.internal.creation.bytebuddy.InlineDelegateByteBuddyMockMaker class

Further reading has led me to try using ArgumentCaptors and the following works, although much more verbose than I would like.

ArgumentCaptor<String> argument = ArgumentCaptor.forClass(String.class);

verify(errors, atLeastOnce()).add(argument.capture(), any(ActionMessage.class));

List<String> values = argument.getAllValues();

assertTrue(values.contains("exception.message"));
assertTrue(values.contains("exception.detail"));

Since I didn't get any response here I asked on the Mockito forums. Here is a link to the discussion: https://groups.google.com/d/topic/mockito/hWwcI5UHFi0/discussion

To summarize the answers, technically this would kind of defeat the purpose of mocking. You should really only mock the objects needed by the SystemUnderTest class. Mocking things within objects that are themselves mocks is kind of pointless.

If you really wanted to do it, @spy can help

Try Cntrl + Shift + T on your eclipse screen. Check what are your results. Ideally eclipse should resolve this class only from one dependency. If you are getting multiple results, you may need to add exclusion on certain dependencies.

Also check if you are able to execute your test cases from command prompt. If you are able to do it, then it's not a maven problem. But if something is failing here, check your dependencies.

I have AngularJS 2 + Spring Boot application with Gradle. I use typescript (.ts file) and npm (node js package manager). So I'm running npm install for generate node_modules and npm run tsc for translating typescript to javascript. I still use some of webjars though, basically dependencies are gathered by npm task during build time and wired by systemjs.config.js file

Below is my folder structure

/src/main/java
/src/main/resources
                   /app           - .ts files and .js translated from .ts
                   /css
                   /js            - systemjs.config.js
                   /node_modules  - generated by npm install
                   /typings       - generated by npm install
                   package.json
                   tsconfig.json
                   typings.json
/src/main/webapp/WEB-INF/jsp      - .jsp files

This is my build.gradle file and add two custom tasks (npmInstall and npmRunTsc) to run npm tasks

build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.5.RELEASE")
        classpath("org.flywaydb:flyway-gradle-plugin:3.2.1")
    }
}

    standardOutput = new ByteArrayOutputStream()
    ext.output = {

                )
}

task wrapper(type: Wrapper) {
    gradleVersion = '1.11'
}

When I run the gradle build process I run like below

$ gradle clean npmInstall npmRunTsc test bootRepackage

I can use same systemjs.config.js shown on AngularJS tutorial

systemjs.config.js

(function(global) {
  // map tells the System loader where to look for things
  var map = {
    'app':                        'app', // 'dist',
    'rxjs':                       'node_modules/rxjs',
    'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
    '@angular':                   'node_modules/@angular'
  };
  // packages tells the System loader how to load when no filename and/or no extension
  var packages = {
    'app':                        { main: 'main.js',  defaultExtension: 'js' },
    'rxjs':                       { defaultExtension: 'js' },
    'angular2-in-memory-web-api': { defaultExtension: 'js' },
  };
  var packageNames = [
    '@angular/common',
    '@angular/compiler',
    '@angular/core',
    '@angular/http',
    '@angular/platform-browser',
    '@angular/platform-browser-dynamic',
    '@angular/router',
    '@angular/router-deprecated',
    '@angular/testing',
    '@angular/upgrade',
  ];
  // add package entries for angular packages in the form '@angular/common': { main: 'index.js', defaultExtension: 'js' }
  packageNames.forEach(function(pkgName) {
    packages[pkgName] = { main: 'index.js', defaultExtension: 'js' };
  });
  var config = {
    map: map,
    packages: packages
  }
  System.config(config);
})(this);

And on .jsp file I include the systemjs.config.js in head section

<script type="text/javascript" src="node_modules/zone.js/dist/zone.js"></script>
<script type="text/javascript" src="node_modules/reflect-metadata/Reflect.js"></script>
<script type="text/javascript" src="node_modules/systemjs/dist/system.src.js"></script>
<script type="text/javascript" src="js/systemjs.config.js"></script>

For last, to sort out context path I do like below on my Spring WebMvcConfigurerAdapter

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.my.controller")
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        if (!registry.hasMappingForPattern("/webjars/**")) {
            registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
        }
        if (!registry.hasMappingForPattern("/images/**")) {
            registry.addResourceHandler("/images/**").addResourceLocations("classpath:/images/");
        }
        if (!registry.hasMappingForPattern("/css/**")) {
            registry.addResourceHandler("/css/**").addResourceLocations("classpath:/css/");
        }
        if (!registry.hasMappingForPattern("/js/**")) {
            registry.addResourceHandler("/js/**").addResourceLocations("classpath:/js/");
        }
        if (!registry.hasMappingForPattern("/app/**")) {
            registry.addResourceHandler("/app/**").addResourceLocations("classpath:/app/");
        }
        if (!registry.hasMappingForPattern("/node_modules/**")) {
            registry.addResourceHandler("/node_modules/**").addResourceLocations("classpath:/node_modules/");
        }
    }

    @Bean
    public InternalResourceViewResolver internalViewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/jsp/");
        viewResolver.setSuffix(".jsp");
        viewResolver.setOrder(1);
        return viewResolver;
    }
}

As of now (18/03/2022) Mockito supports mocking static methods. You can do

@Test
public void testDate() {
    String instantExpected = "2022-03-14T09:33:52Z";
    ZonedDateTime zonedDateTime = ZonedDateTime.parse(instantExpected);

    try (MockedStatic<ZonedDateTime> mockedLocalDateTime = Mockito.mockStatic(ZonedDateTime.class)) {
        mockedLocalDateTime.when(ZonedDateTime::now).thenReturn(zonedDateTime);

        assertThat(yourService.getCurrentDate()).isEqualTo(zonedDateTime);
    }
}

Please note that you need to use mockito-inline dependency:

    <dependency>
        <groupId>org.mockito</groupId>
        <artifactId>mockito-inline</artifactId>
        <version>4.4.0</version>
    </dependency>

That should be as simple as writing the following test class:

public class BarTest {
    @Test
    public void testFooIsInitializedProperly() throws Exception {
        // Arrange
        Bar bar = new Bar();

        // Act
        bar.initFoo();

        // Assert
        Foo foo = Whitebox.getInternalState(bar, "foo");
        assertThat(foo, is(notNull(Foo.class)));
    }
}

Adding the right (static) imports is left as an exercise to the reader :).

From the Mockito FAQ:

What are the limitations of Mockito

• Cannot mock final methods - their real behavior is executed without any exception. Mockito cannot warn you about mocking final methods so be vigilant.

My solution was to update my global ~/.gradle/gradle.properties file with the correct proxy settings:

org.gradle.daemon=true
systemProp.https.proxyHost=proxy.company.net
systemProp.https.proxyPort=8181
systemProp.http.proxyHost=proxy.company.net
systemProp.http.proxyPort=8181
systemProp.https.nonProxyHosts=*.company.com|localhost

this is in effect, the same as passing these as command line args to gradlew (./gradlew -Dhttp.proxyHost=xxx -Dhttp.proxyPort=xxx -Dhttps.proxyHost=xxx -Dhttps.proxyPort=xxx

You can also use @InjectMocks annotation, that way you wont need any getters and setters. Just make sure you add below in your test case after annotating your class,

@Before
public void initMocks(){
    MockitoAnnotations.initMocks(this);
}
