### Question:
BSHLogListener implements org.jpos.util.LogListener, org.jpos.core.Configurable { @Override public void setConfiguration(org.jpos.core.Configuration cfg) { this.cfg = cfg; } BSHLogListener(); @Override void setConfiguration(org.jpos.core.Configuration cfg); @Override LogEvent log(LogEvent ev);  }### Answer:
@Test public void testSetConfiguration() throws Throwable { BSHLogListener bSHLogListener = new BSHLogListener(); Configuration cfg = new SimpleConfiguration(new Properties()); bSHLogListener.setConfiguration(cfg); assertSame(cfg, bSHLogListener.cfg, "bSHLogListener.cfg"); }
