### Question:
SimpleLogSource implements LogSource { public void setRealm (String realm) { this.realm = realm; } SimpleLogSource();  SimpleLogSource(Logger logger, String realm); void setLogger(Logger logger, String realm); String getRealm(); Logger getLogger(); void setRealm(String realm); void info(String detail); void info(String detail, Object obj); void warning(String detail); void warning(String detail, Object obj); void error(String detail); void error(String detail, Object obj);  }### Answer:
@Test public void testSetRealm() throws Throwable { SimpleLogSource bSHTransactionParticipant = new BSHTransactionParticipant(); bSHTransactionParticipant.setRealm("testSimpleLogSourceRealm"); assertEquals("testSimpleLogSourceRealm", ((BSHTransactionParticipant) bSHTransactionParticipant).realm, "(BSHTransactionParticipant) bSHTransactionParticipant.realm"); }
