Writing unit test with spring

Question

I'm new in unit-testing and trying to intanciate ApplicationContext in a unit-test as follows:

ApplicationContext context;

@Before
public void init(){
    context = new ClassPathXmlApplicationContext("classpath://webapp/WEB-INF/applicationContext-sheduler.xml");
}

But when I try to do so I get the exception:

2015-05-29 10:20:13,494 ERROR Unable to create file ${sys:catalina.home}/logs/partner-sheduler.log java.io.IOException: The filename, directory name, or volume label syntax is incorrect

2015-05-29 10:20:13,534 ERROR Unable to locate appender R for logger

How to fix that?

The test doesn't contain anything except the Before method and an empty method annotatted with @Test.

Fix the log file name in lgo4j config. The first line of stack trace points towards it `Unable to create file ${sys:catalina.home}/logs/partner-sheduler.log java.io.IOException: The filename, directory name, or volume label syntax is incorrect` — Bond - Java Bond, May 29 '15 at 06:26
`${sys:catalina.home}` will not work in log4j config file as long as you do not set `catalina.home` environment var. Check [this](http://stackoverflow.com/questions/10769667/how-to-set-catalina-home-in-log4j-xml) out — Fran Montero, May 29 '15 at 06:28
@FranMontero So I should pass catalina.home as a JVM option, right? — St.Antario, May 29 '15 at 06:29
@FranMontero Don't see how I can pass a JVM option when I'm running unit-tests under eclipse. — St.Antario, May 29 '15 at 06:36
@St.Antario `right-click -> run configurations -> Junit (right click -> new) -> arguments` if you are running the test another way check http://stackoverflow.com/questions/7579776/how-to-set-jvm-parameters-for-junit-unit-tests question — Fran Montero, May 29 '15 at 06:41
@FranMontero That works perfectly. Thank you. But now I got another exception while running the unit-test. __COnfiguration file doesn't exist__ — St.Antario, May 29 '15 at 06:45
@St.Antario Great! I'm writing an answer, if you have a new error try to solve it yourself and if you can't post another question ;) — Fran Montero, May 29 '15 at 06:47

In order to use environment variables in log4j.propertiesconfiguration file, you have to pass the argument you need to the JVM when running the test. YOu can achieve that with a run configutarion:

right-click -> run configurations -> Junit (right click -> new) -> arguments

if you are running the test another way check How to set JVM parameters for Junit Unit Tests?
