Why can't I test my project using JUnit 4?

Why can't I test my project using JUnit 4? - java

I am using Spring 3, Hibernate 3 in my project. But I can not test it using JUnit 4.
Here is my Test class:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations={"file:WebRoot/WEB-INF/applicationContext.xml"})
public class UserDaoTestCase extends AbstractJUnit4SpringContextTests {
#Autowired
private UserDao userDao;
#Test
public void testSimple() {
// do some tests...
}
// setters and getters
public UserDao getUserDao() {
return userDao;
}
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
}
I run this test, and I always get this exception:

My IDE is MyEclipse 9, and I am using JavaEE 6 libraries.
I think my applicationContext.xml is fine, 'cuz it works fine when I run this project in tomcat, no exceptions.
Here is my SessionFactory bean in applicationContext.xml:
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="c3p0DataSource" />
<property name="packagesToScan">
<list>
<value>com.myproject.entity</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.connection.provider_class">
org.hibernate.connection.C3P0ConnectionProvider
</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
</props>
</property>
</bean>
How can I do tests using JUnit 4 correctly?

I expect you've got the path to the application-context.xml wrong, as Spring sees it. I'd first try dropping off WebRoot/.
I'd attach the Spring sources to my project and hook-up a debugger, breaking on line:
org.springframework.test.context.TestContext.getApplicationContext(TestContext.java:308)
In there, you'll see where it's loading the application context and you can use an interactive expression executer to try multiple different strings to figure out what it can and can't see.
I'd also try this:
#ContextConfiguration(locations = { "classpath*:applicationContext*.xml" })
That work's in my project where the files are in WEB-INF/classes in the deployment.

Do you really use your production applicaton context for tests?
I would change the approach to use a different application context for tests (e.g. for defining test data sources and stuff) and place it along with your other test resources. Then a simple lookup as the following one will do.
#ContextConfiguration("/path/to/my/test-context.xml")
In your example, you have to make sure the path is correct! Your file URL should be translated to a folder relative to your project's root folder. Does the application context lie there?

#ContextConfiguration(locations={"file:WebRoot/WEB-INF/applicationContext.xml"})
I think you do not locate your Spring context configuration file from file:// . re-locate it.

I also had this problem, in my case the problem was with the application context xml configuration file being loaded. It was not a properly defined application context. To be precise, "xmlns:context="http://www.springframework.org/schema/context" namespace was missing.

I too have same problem, When I updated both src/test/resources/ApplicationResource.properties and src/main/resources/ApplicationResource.proerties.
And I updated, POM.xml with context and test dependency
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${org.springframework-version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>${org.springframework-version}</version>
</dependency>
The src/test/resources/ApplicationContext.xml loaded successfully.
My problem got solved.

Openshift Unable to locate persistence units

I'm developing Hibernate JPA persistance web application, with my persistence.xml in src/main/resources/META-INF/persistence.xml (in war file it's in WEB-INF/classes/META-INF). It all works well on local Tomcat server, but when put on Openshift JBoss EWS, getting this message on startup:

and has two persistence units in it. I alse deleted hibernate.cfg.xml, both things suggested in other SO answers. Anyone know what I'm doing wrong here?

Got it.
The problem was I used Persistence.createEntityManagerFactory("unit") to create EntityManagerFactory and injected it in other Spring beans.
Now I put
<bean id="emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitName" value="unit" />
</bean>
directly in applicationContext.xml.
Still doesn't explain what was wrong with previous approach, but it works.

dataSource injection in SpringFramework2 throws exception

I use the Spring Framework 2.5.6
I have the following dataSource defined in my spring-beans.xml file which I use in order to connect in my remote database :
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/sample"/>
<property name="username" value="root"/>
<property name="password" value="root"/>
</bean>
This is how my jUnit integration test looks like :
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = "spring-beans.xml")
public class MyIntegrationTest {
#Autowired
DataSource dataSource;
}
I have copied the spring-beans.xml file in the same package where the test case code which I have uploaded resides.
However I get the following exception when I run the test case :

Any ideas why this could be happening ?

You need to put spring-beans.xml into the classpath--not the package where your source code is.
If you are using Maven or Gradle to build, then put the file in src/test/resources.
Otherwise, put it wherever and manually load it with FileSystemXmlApplicationContext in the setup for your test fixture.

If you are using Maven you should use the src/test/resources folder. Maven can copy it over while running the tests.

Spring Dependency Injection from JAR

I have dao layer which is in project A and project B is application layer which uses project A as it's dependency
I can see the classes from project A and coded perfectly in project B using those classes.
Now I want to do JUnit testing
in A (MyTest.java)
#TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)
#ContextConfiguration(locations = { "classpath*:reb/spring/persistenceContextTest.xml", "classpath*:rev/spring/modelContextTest.xml" })
public class MyTest extends AbstractTransactionalJUnit4SpringContextTests {
#Autowired
protected HibernateTemplate hibernateTemplate;
#Autowired
protected DAOImpl dao;
//CODE here
}
Everything is fine here. All properties are injected properly and no issues.
Now I need to test Application Layer {project b}
#ContextConfiguration(locations = { "classpath*:reb/spring/applicationContextTest.xml" })
public class MyAnotherTest extends AbstractTransactionalJUnit4SpringContextTests {
#Autowired
protected HibernateTemplate hibernateTemplate;
#Autowired
protected DAOImpl dao;
}
and in applicationContextTest.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<import resource="classpath*:reb/spring/persistenceContextTest.xml" />
<import resource="classpath*:reb/spring/modelContextTest.xml" />
</beans>
but when I run the B test, Spring is unable to find the properties defined in project A.
How do i achieve this?
Update
I moved test xmls to Src folder so that maven recognize in Project B and indeed it recognized.
however I am getting below error still

if you are using maven, then any resources and sources in src/test are local the individual module, i.e. anything in projectA/src/test will be hidden from projectB. There are multiple options available:
Move Test Resources: I would discourage you from doing this, but basically you can move your applicationContextTest.xml to the src/main folder, but then you have test code in your binary deliverables.
Replicate Test Resources: This is not as bad as the previous suggestion, when you copy any bean setup from projectA to projectB. This usually implies that you are creating test application contexts for your unit tests and that you have different application contexts for your real application.
Delete all Test Application Contexts: This would be the cleanest solution, if you dont have any test context you are forced to test the real thing. If you need environment specific properties you can use PropertyPlaceHolders, if you need different beans (Connection Pools, etc.) you can use Profiles.
Have a look at the new Spring 3.1 Feature for Profiles: http://blog.springsource.org/2011/02/14/spring-3-1-m1-introducing-profile/

Your test persistence context xml name is same in project A and project B. Can you try changing the name persistenceContextTest.xml in project A to persistenceContextTestA.xml to be sure that the problem is not because of duplicate file name.

BeanCreationException NoSuchBeanDefinitionException using Spring roo

I am getting an exception thrown when i attempt to access my service, i used spring roo to create my spring data jpa repository which generated the file applicationContext-jpa.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/data/jpa"

My applicationContext.xml is in the same directory META-INF/spring/ and i have made sure to include the component-scan

<context:exclude-filter expression=".*_Roo_.*" type="regex"/>
<context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
</context:component-scan>
The test use case in how i am using it, is below:
#RooIntegrationTest(entity = UserAccount.class)
#ContextConfiguration(locations = { "classpath:META-INF/spring/applicationContext.xml" })
public class UserAccountIntegrationTest extends AbstractJUnit4SpringContextTests {
#PersistenceUnit(unitName = "persistenceUnit")

PasswordService testsPasswordService = new CustomPasswordService();
#Autowired
private AccountSettingsRepository accountSettingsRepository;
#Autowired
private AccountService accountService;
#Test
public void testAccount(){
accountService.saveAccountSettings(accountSettings);
Assert.assertNotNull(accountSettings);
}
I cant figure out what could be causing this exception, i told it exactly where to find the service implementation and repository. Full stack trace is below:

Check that your applicationContext-jpa.xml is loaded by your main context.
To do that, check that your applicationContext.xml contains:
<import resource="applicationContext-jpa.xml"/>

You're not loading the applicationContext-jpa.xml in your test. Modify the locations attribute within the ContextConfiguration annotation of the UserAccounIntegrationTest.
You'd better let Roo to create the tests with "-testAutomatically" in the "entity" command or using the command "integration test".
Roo will create the appropriate location using a wildcard: "classpath:META-INF/spring/applicationContext*.xml" in an AspectJ file (.aj) for the integration test.
NOTE: if you want to add your own applicationContex-test.xml in the test/resources folder, you need to modify the locations by adding a '' after classpath: "classpath:..."

SQLException w/ Tomcat 7.0 JDBC connection pool and MySql

I'm trying to use the new Tomcat 7.0 JDBC connection pool and MySql. It says here that you can drop the latest tomcat-jdbc.jar into your tomcat/lib directory in a Tomcat 6.0 environment, and that's what I've done.
I'm using Spring to initialize and instantiate the DataSource per examples around the web:
<bean id="myDataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close"
p:driverClassName="${driver_class}"
p:url="${url}"
p:username="${username?root}"
p:password="${password}"
p:initialSize="10"
p:initSQL="SELECT DTS FROM DT_TM_TS FOR READ ONLY WITH UR"
p:minIdle="10"
p:maxIdle="100"
p:maxActive="100"
p:maxWait="6000"
p:jmxEnabled="true"
p:jdbcInterceptors="org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer"
p:removeAbandoned="true"
p:removeAbandonedTimeout="60"
p:logAbandoned="true"
p:testOnBorrow="true"
p:testOnReturn="false"
p:testWhileIdle="false"
p:useEquals="false"
p:fairQueue="false"
p:timeBetweenEvictionRunsMillis="30000"
p:minEvictableIdleTimeMillis="30000"
p:validationInterval="1800000"
p:validationQuery="SELECT DTS FROM DT_TM_TS FOR READ ONLY WITH UR"
/>
However when I try to connect to the db it throws this exception:

I've got mysql-connector-java-5.1.13-bin.jar in both the webapp WEB-INF/lib and tomcat/lib. I can connect fine specifying the driver details in persistence.xml (no DataSource/connection pooling).

There is actually a very simple workaround with Spring. Instead of having the Tomcat connection pool create the database connection and fail because of class loader shenanigans, let Spring create it and pass a reference to the connection pool.
<!-- Data source template for use in the connection pool. -->
<bean id="dataSourceTemplate" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driver}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>
<!-- Connection pool as data source. -->
<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close">
<!-- Refer to a separately created bean as a data source template to work around a quirk of Tomcat's class loader. -->
<property name="dataSource" ref="dataSourceTemplate" />
...
</bean>
Then the connection pool will actually use the database connection as a template for creating as many additional connections as it needs.
The best part is that you don't have to mess with tomcat/lib, which you may not even have access to.

I'm using Spring 3.1, Hibernate 4.0, VMware vFabric tc Server Developer Edition 2.6.1 with Tomcat 7.0.20.B and Maven 3. Having the connector managed by Maven I encountered the same issue.
Infact reading the manual I've found
driverClassName
(String) The fully qualified Java class name of the
JDBC driver to be used. The driver has to be accessible from the same
classloader as tomcat-jdbc.jar
So I resolved by adding the mysql connector (mysql-connector-java-5.1.18-bin.jar) in the lib directory of Tomcat (vfabric-tc-server-developer-2.6.1.RELEASE/tomcat-7.0.20.B.RELEASE/lib) and setting in Maven the scope of the connector package to provided.

In Tomcat 6.0 I need to put my JDBC drivers into common/lib/ext
But the search path for that is configured in catalina.properties check out the property common.loader in there. Make sure that common/lib is listed there.

Develop Reference

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Why can't I test my project using JUnit 4? - java

#ContextConfiguration(locations={"file:WebRoot/WEB-INF/applicationContext.xml"}) I think you do not locate your Spring context configuration file from file:// . re-locate it.

I also had this problem, in my case the problem was with the application context xml configuration file being loaded. It was not a properly defined application context. To be precise, "xmlns:context="http://www.springframework.org/schema/context" namespace was missing.
