我该如何处理是安装一个安全管理器,该安全管理器在调用System.exit时会引发异常。然后是捕获异常且不会使测试失败的代码。
public class NoExitSecurityManager
extends java.rmi.RMISecurityManager
{
private final SecurityManager parent;
public NoExitSecurityManager(final SecurityManager manager)
{
parent = manager;
}
public void checkExit(int status)
{
throw new AttemptToExitException(status);
}
public void checkPermission(Permission perm)
{
}
}
然后在代码中,如下所示:
catch(final Throwable ex)
{
final Throwable cause;
if(ex.getCause() == null)
{
cause = ex;
}
else
{
cause = ex.getCause();
}
if(cause instanceof AttemptToExitException)
{
status = ((AttemptToExitException)cause).getStatus();
}
else
{
throw cause;
}
}
assertEquals("System.exit must be called with the value of " + expectedStatus, expectedStatus, status);
