PermGen when unit testing a web script

[alex_lu]

Hello everyone,

I'm following this wiki about writing test case for web script. http://wiki.alfresco.com/wiki/3.0_Web_Scripts_Testing.

I'm actually using 3.4 and resolved all the dependencies issue. However, I'm getting a PermGen when I run a sample test case.

Basically, I deliberately made a mistake in the json object and exception gets thrown back is actually valid exception message without permgen problem.

However if the json object contains all the information to create a user, then it slips into PermGen. I run the test case in eclipse and have increased MaxPermSize = 3056m. I don't think this is correct to give such large perm size for running test cases anyway.

Anyone got the same problem and solution? Thanks lots.

Hi,

I'm running into the same problem. Did you fix it allready?

grtz,
Bart

Alfresco needs a permgen of about 200M, bigger than the default but nowhere near 3G.  

You have an infinite loop somwehere.

My tests runned in intellij but not in maven commandline. I fixed it with following config :

                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
            <version>2.11</version>
                <configuration>
                    <forkMode>once</forkMode>
                    <argLine>-Xms128m -Xmx512m -XX:MaxPermSize=256m</argLine>
                </configuration>
