### Question:
SimpleLogSource implements LogSource { public String getRealm () { return 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 testGetRealm() throws Throwable { SimpleLogSource bSHTransactionParticipant = new BSHTransactionParticipant(); bSHTransactionParticipant.setRealm("testSimpleLogSourceRealm"); String result = bSHTransactionParticipant.getRealm(); assertEquals("testSimpleLogSourceRealm", result, "result"); }
@Test public void testGetRealm1() throws Throwable { String result = new BSHTransactionParticipant().getRealm(); assertNull(result, "result"); }
