how to run RunWith with Junit 5 in java eclipse? - java

i want to run #RunWith with few classes in Junit 5 and attached my dependencies that i did plus the code , but only one class is runing = someTest , what i missed over here ?
class someTest
import org.junit.jupiter.api.Test;
import org.junit.platform.suite.api.SelectClasses;
#RunWith(JUnitPlatform.class)
#SelectClasses( { Something.class, someTest.class } )
public class someTest {
#Test
public void sadsadas() {
System.out.println("these is the runWith");
}
}
class something
import java.util.logging.ConsoleHandler;
import java.util.logging.FileHandler;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.logging.SimpleFormatter;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Tag;
import org.junit.jupiter.api.Test;
public class Something {
Logger logger = Logger.getLogger("");
FileHandler fh;
#BeforeEach
public void wallad() {
System.out.println("hello");
}
#AfterEach
public void asddf() {
System.out.println("pizza");
}
#Tag("test")
#Test
public void some() {
try {
fh = new
FileHandler("C:\\Users\\tester\\Desktop\\MyLogFile.txt");
logger.addHandler(fh);
SimpleFormatter formatter = new SimpleFormatter();
fh.setFormatter(formatter);
} catch (Exception e) {
e.printStackTrace();
}
logger = Logger.getLogger(Logger.class.getName());
logger.setLevel(Level.ALL);
ConsoleHandler handler = new ConsoleHandler();
handler.setLevel(Level.ALL);
logger.addHandler(handler);
logger.setUseParentHandlers(false);
System.out.println("test1");
logger.log(Level.WARNING, "warning");
System.out.println("test2");
logger.log(Level.INFO, "information");
System.out.println("test3");
logger.log(Level.SEVERE, "severe");
System.out.println("test4");
logger.log(Level.FINEST, "finest");
System.out.println("test5");
logger.log(Level.FINE, "fine");
System.out.println("test6");
logger.log(Level.FINER, "finer");
System.out.println("test7");
logger.log(Level.FINEST, "finest");
}
}
these is the dependencies that attach to maven

what i missed in terms of the runWIth? or that in junit5 i need to write only:
#SelectClasses( { Something.class, someTest.class } )
i am runing Eclipse Jee 2018-09

Rename Something.class to SomethingTest.class it will work.
#SelectClasses({ SomethingTest.class, someTest.class })

junit.framework.AssertionFailedError: No tests found in org.example.AppTest

I started to learn about automation testing and I am trying to testing with Intellij using apache-maven 1.8 & selenium-server. I have also installed JDK11. and I try to exercise by testing web, so I created two classes which are homepage & apptest.
Here is my code (homepage.java)
package org.example.page;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import static junit.framework.Assert.assertEquals;
public class homepage {
private WebDriver webDriver;
public homepage(WebDriver driver) {
this.webDriver = driver;
}
public void assertOpenHomePage() throws InterruptedException {
Thread.sleep(3000);
String welcomeHomePage = String.valueOf(webDriver.findElement(By.xpath
("//strong[contains(text(),'Selenium Easy!')]")).getText());
assertEquals("Selenium Easy!", welcomeHomePage);
}
and this is the code for the apptest (apptest.java)
package org.example;
import junit.framework.TestCase;
import org.example.page.homepage;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
/**
* Unit test for simple App.
*/
public class AppTest
extends TestCase
{
WebDriver webDriver;
#Before
public void initiate(){
ChromeOptions options = new ChromeOptions();
options.addArguments("Start-Maximized");
webDriver = new ChromeDriver(options);
}
#Test
public void openHomePage() throws InterruptedException {
homepage homepage = new homepage(webDriver);
webDriver.get("https://www.seleniumeasy.com/");
homepage.assertOpenHomePage();
}
}
but when i run the apptest.java, there such an error report:
junit.framework.AssertionFailedError: No tests found in org.example.AppTest
at junit.framework.Assert.fail(Assert.java:57)
at junit.framework.TestCase.fail(TestCase.java:223)
at junit.framework.TestSuite$1.runTest(TestSuite.java:96)
Please help me to resolve this problem, thank you so much!
If using that particular junit library is not mandatory, you may try this junit-jupiter
Page Class:
package pages;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
public class HomePage {
private WebDriver webDriver;
public HomePage(WebDriver driver) {
this.webDriver = driver;
}
public String assertOpenHomePage() throws InterruptedException {
Thread.sleep(3000);
String welcomeHomePage = String.valueOf(webDriver.findElement(By.xpath
("//strong[contains(text(),'Selenium Easy!')]")).getText());
return welcomeHomePage;
}
}
TestClass:
import io.github.bonigarcia.wdm.WebDriverManager;
import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import pages.HomePage;
import static org.junit.jupiter.api.Assertions.assertEquals;
public class AppTest {
static WebDriver webDriver;
#BeforeAll
public static void initiate(){
WebDriverManager.chromedriver().setup();
ChromeOptions options = new ChromeOptions();
options.addArguments("Start-Maximized");
webDriver = new ChromeDriver(options);
}
#Test
public void openHomePage() throws InterruptedException {
HomePage homepage = new HomePage(webDriver);
webDriver.get("https://www.seleniumeasy.com/");
assertEquals("Selenium Easy!", homepage.assertOpenHomePage());
}
}
My pom.xml dependencies:
<dependencies>
<!-- https://mvnrepository.com/artifact/junit/junit -->

Or we can also use TestNG that has even more flexibility.

My Test annotation not working, eclipse is asking for main method

I have trying selenium code with #Test, but eclipse is not running it and asking for Main method.
I've added Maven Project and added Selenium & TestNG dependencies to pom.xml
Please help with the issue I'm facing

I think you should install TestNG for your IDE. You can check this link for more details.

Why I cannot use expected in JUnit 4

Im trying to test method responsible for retreiving data from file.
I want to test if exception is thrown properly.
package contentfile;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.stream.Stream;
public class ContentFileRetrieverService implements ContentFileRetriever {
#Override
public String[] getContentFile(String pathName) {
Stream<String> contentFileStream;
try {
contentFileStream = Files.lines(Paths.get(pathName));
} catch (IOException e) {
throw new IllegalArgumentException(e);
}
return contentFileStream.toArray(String[]::new);
}
}
My tests:
package contentfile;
import org.junit.jupiter.api.Test;
import static org.junit.Assert.*;
class ContentFileRetrieverServiceTest {
private ContentFileRetrieverService contentFileRetrieverService = new ContentFileRetrieverService();
#Test
void getContentFile() {
String pathFile = "src\\test\\java\\resources\\TestText.txt";
String[] testedContent = contentFileRetrieverService.getContentFile(pathFile);
String[] expected = {"Line1 a", "Line2 b c", "Line 3"};
assertArrayEquals(expected, testedContent);
}
#Test(expected = IllegalArgumentException.class)
void getContentFileWhenFileDoesNotExist() {
String pathFile = "unknown";
String[] testedContent = contentFileRetrieverService.getContentFile(pathFile);
}
}
pom,xml
<dependency>
<groupId>org.junit.jupiter</groupId>

It wont compile as it cannot resolve method excepted what I am making wrong?
PS:
Could you tell me if I test this method properly with these two methods?
You're mixing JUnit 4 and JUnit 5.
The expected element exists in the JUnit4 #Test
JUnit 5 offers more powerful assertThrows instead

Swagger with Jersey 2 throws java.lang.NoClassDefFoundError: javax/servlet/ServletConfig

Trying to setup my first REST API (using Jersey 2 and Gradle) and add some documentation to it by using swagger. But when adding swagger dependencies and following this swagger documentation, "Using a custom Application subclass" approach, it throws me this exception, when executing the main method from Eclipse:

My code looks like this:
package example;

System.out.println("SERVICE started at: " + baseUri);
Runtime.getRuntime().addShutdownHook(new Thread(() -> {

}));
}
public MyApp() {
packages("example");
register(SwaggerSerializers.class); // <-- swagger specific
register(ApiListingResource.class); // <-- swagger specific
register(JacksonFeature.class);
}
}
My gradle dependencies
dependencies {
compile 'com.fasterxml.jackson.jaxrs:jackson-jaxrs-json-provider:+'
compile 'org.glassfish.jersey.containers:jersey-container-jdk-http:+'
compile 'org.glassfish.jersey.media:jersey-media-moxy:+'
compile 'org.glassfish.jersey.media:jersey-media-json-jackson:+'
compile 'io.swagger:swagger-jersey2-jaxrs:1.5.9'
}
Using jdk1.8.0_77 on Windows 7
However, if I comment out the swagger dependency and the swagger specifics in the code, then the actual REST service works as expected. How can I make swagger work without using a servlet container? The REST service can work without it
dependencies {
compile 'com.fasterxml.jackson.jaxrs:jackson-jaxrs-json-provider:+'
compile 'org.glassfish.jersey.containers:jersey-container-jdk-http:+'
compile 'org.glassfish.jersey.media:jersey-media-moxy:+'
compile 'org.glassfish.jersey.media:jersey-media-json-jackson:+'
// compile 'io.swagger:swagger-jersey2-jaxrs:1.5.9'
}
code:
package example;
import static org.glassfish.jersey.jdkhttp.JdkHttpServerFactory.createHttpServer;
import java.net.URI;
import javax.ws.rs.core.UriBuilder;
import org.glassfish.jersey.jackson.JacksonFeature;
import org.glassfish.jersey.server.ResourceConfig;
import com.sun.net.httpserver.HttpServer;
import io.swagger.jaxrs.listing.ApiListingResource;
import io.swagger.jaxrs.listing.SwaggerSerializers;
public class MyApp extends ResourceConfig {
public static void main(String[] args) throws Throwable {
URI baseUri = UriBuilder.fromUri("http://localhost/").port(9999).build();
HttpServer server = createHttpServer(baseUri, new MyApp());
System.out.println("SERVICE started at: " + baseUri);
Runtime.getRuntime().addShutdownHook(new Thread(() -> {
server.stop(0);
}));
}
public MyApp() {
packages("example");
// register(SwaggerSerializers.class); // <-- swagger specific
// register(ApiListingResource.class); // <-- swagger specific
register(JacksonFeature.class);
}
}
So it looks like the issue is derived from you running in a non-servlet environment. While Jersey supports it, swagger-core... not so much. This poses some issues with specific deployment, although they are less common.
The easiest solution would, obviously, be to use a servlet-container engine. Something lightweight like Jetty would work.
I know that is a litlle bit late, but I have the same issue and came up with a solution to run swagger on a non-servlet environment.
Hope to be helpful for the next devs.

I was facing the same issue, I solved it by following the same swagger documentation, The only difference is that I provided my own ApiListingResource implementation
package com.example;
import com.fasterxml.jackson.core.JsonProcessingException;
import io.swagger.annotations.ApiOperation;
import io.swagger.jaxrs.config.BeanConfig;
import io.swagger.models.Swagger;
import io.swagger.util.Yaml;
import javax.enterprise.context.ApplicationScoped;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Response;
#Path("/docs")
#ApplicationScoped
public class ApiListingResource {
private final Swagger swagger;
public ApiListingResource() {
BeanConfig beanConfig = new BeanConfig();
beanConfig.setTitle("MY REST API");
beanConfig.setVersion("v1");
beanConfig.setBasePath("/api");
beanConfig.setResourcePackage("com.example.resource");
beanConfig.setScan(true);
this.swagger = beanConfig.getSwagger();
}
#GET
#Produces({"application/json"})
#Path("/swagger.json")
public Response getListingJson() {
return Response.ok(this.swagger).build();
}
#GET
#Produces({"application/yaml"})
#Path("/swagger.yaml")
public Response getListingYaml() throws JsonProcessingException {
String yaml = Yaml.mapper().writeValueAsString(this.swagger);
return Response.ok(yaml).build();
}
}
Then I registered the resource along with the SwaggerSerializers provider.

Spring's SimpleNamingContextBuilder and LDAP

I'm currently trying to develop a new module for our existing web application. I'm trying to add LDAP functionality and have problems initializing the LDAP context as the SimpleNamingContextBuilder registers a context that is not working together with the LdapTemplate.
In our spring applicationContext.xml we have several JNDI lookups, so before running a test case I have to create mock JNDI-Resources using the SimpleNamingContextBuilder in the test cases constructor.
SimpleNamingContextBuilder builder = new SimpleNamingContextBuilder();
builder.bind("someJNDIname",someObject); //e.g. for some datasource
builder.activate();
In our Spring application-context-test.xml we have the following ldapConfiguration:
<bean id="ldapContextSource" class="org.springframework.ldap.core.support.LdapContextSource">
<property name="url" value="ldap://ourserver:389" />
<property name="base" value="CN=Groups,CN=ourcompany,DC=com" />
<property name="userDn" value="CN=binduser" />
<property name="password" value="password" />
</bean>
<bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
<constructor-arg ref="ldapContextSource" />
</bean>
We run the testcase with:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = {"classpath:application-context-test.xml"})
public class TestClass {
public TestClass(){
.. //init the SimpleNamingContextBuilder
}
#Autowired
private LdapTemplate template;
#Test
public void someTestcase(){
ldapTemplate.search("", "(objectclass=user)" ,new LdapUserMapper());
}
}
As the SimpleNamingContextBuilder is already registering a simple InitialContext I get the following error:
org.springframework.ldap.NotContextException: DirContext object is required.; nested exception is javax.naming.NotContextException: DirContext object is required.

The error tells me that the LDAP requires a DirContext. How can I get the SimpleNamingContextBuilder to create and use such a DirContext.
If I don't register the SimpleNamingContextBuilder then creating the LDAPTemplate will work. However I will run into other problems as other parts of the application require the JNDI lookups.
I did not manage to get the SimpleNamingContextBuilder to create an instance of DirContext, but using a custom DirContextBuilder was the solution to get around this limitation.
The mocked SimpleNamingContext is mainly there to provide bound objects via e.g.
InitialContext.doLookup(String name)
methods - to let those ones work and provide proper support for e.g. LDAP DirContext instances, just omit the check for the "activated" context - you will bootstrap your code to apply activate() anyway, so this is no problem - at least not for the given JNDI + LDAP test case.
Missing this check, the code looks for the "java.naming.factory.initial" environment key and if the environment is empty (this is the case for InitialContext.doLookup(String name)) you get the mocked SimpleNamingContext with your bound objects.
If you use the LdapTemplate the environment is not empty and the key "java.naming.factory.initial" is set to "com.sun.jndi.ldap.LdapCtxFactory" or something similar which is at least (hopefully) a DirContext.
In this case you get a working DirContext instance back from the createInitialContextFactory call and the LdapTemplate lookup is successful.
So just create a class DirContextBuilder - take the code from SimpleNamingContextBuilder - like this:
public class DirContextBuilder implements InitialContextFactoryBuilder {
...
public InitialContextFactory createInitialContextFactory(Hashtable<?,?> environment) {
if (environment != null) {
...
}
Omit the check for activated == null and you are ready to test your bound JNDI objects and have a working LdapTemplate.
I faced the same issue. But overcome it with the below trick
#BeforeClass
public static void setUp(){
OracleDataSource ods = null;
try {
ods= new OracleDataSource();
} catch (SQLException e) {
e.printStackTrace();
}
ods.setURL("jdbc:oracle:thin:#(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=....;
ods.setUser(..);
ods.setPassword(..);
SimpleNamingContextBuilder builder = null;
try {
builder = SimpleNamingContextBuilder.emptyActivatedContextBuilder();
builder.bind("some/name", ods);
} catch (NamingException e) {
e.printStackTrace();
}
}
#Before
public void beforeTest(){
SimpleNamingContextBuilder.getCurrentContextBuilder().deactivate();
}
#Test
public void yourTest(){
.....
}
This will bind your database with some/name and also let you to connect to the ldap correctly.
I also faced the same issue. I researched causes and internal behaviour in Java and SpringLdap why it happens. I came to the following decision.
I customized ContextSource bean creation in order to solve it. This method is crutch and requires modification config that checking test mode. But it works.
Below I present simple project demostrated it. For embeded LDAP server I used Apache Directory Server.
