Common problems faced when building junit tests with Spring

Maven pom.xml changes:

1. Add dependency of junit and its version.

    	<dependency>
    	<groupId>junit</groupId>
    	<artifactId>junit</artifactId>
    	<version>4.9</version>
    	<scope>test</scope>
    </dependency>
    
    Scope test specifies to load dependencies during test phase 
    mvn test
   

2. We can load some of the resource files under resources directory to target/test-classes folder if need be

    src                                                                       target
    |                                                                           |
    |----main                                                                   |--------test-classes
          |                copying files from resources to test-classesfolder                                                   
          |--- resources          -------------------->            
   

3. You can specify test-resources in pom.xml for achieving step 2

    	<testResources>
    	<testResource>
    		<directory>src/main/resources/xyz/</directory>
    		<filtering>true</filtering>
    	</testResource>
    	<testResource>
    		<directory>src/test/resources</directory>
    		<filtering>true</filtering>
    	</testResource>
    </testResources>
   

4. Use maven-surefire-plugin to generate reports of tests

5. We can also exclude some classes or folders during compile time for testing. Something like specified below

    		<plugin>
    		<artifactId>maven-compiler-plugin</artifactId>
    		<version>2.0.2</version>
    		<configuration>
    			<source>1.7</source>
    			<target>1.7</target>
    			<debug>true</debug>
    			<debuglevel>lines,vars,source</debuglevel>
    		</configuration>
    		<executions>
    			<execution>
    				<id>default-testCompile</id>
    				<phase>test-compile</phase>
    				<configuration>
    					<excludes>
    						<exclude>xyz/**</exclude>
    					</excludes>
    				</configuration>
    				<goals>
   
    					<goal>testCompile</goal>
    				</goals>
    			</execution>
    		</executions>
    	</plugin>
