### Question:
UpdateSettings implements Cloneable, IUpdateSettings, Serializable { public void setUpdateCheckFrequency(String updateCheckFrequency) { this.updateCheckFrequency = updateCheckFrequency; } UpdateSettings();  UpdateSettings(IUpdateSettings updateSettings); @Override Object clone(); String getUpdateServer(); void setUpdateServer(String updateServer); String getUpdateServerPort(); void setUpdateServerPort(String updateServerPort); String getUpdateServerPath(); void setUpdateServerPath(String updateServerPath); String getUpdateServerChannel(); void setUpdateServerChannel(String updateServerChannel); boolean isEnableAutomaticUpdates(); void setEnableAutomaticUpdates(boolean enableAutomaticUpdates); String getUpdateCheckFrequency(); void setUpdateCheckFrequency(String updateCheckFrequency); String getLastUpdateCheckTimeMillis(); void setLastUpdateCheckTimeMillis(String lastUpdateCheckTimeMillis); boolean isRemoteUpdateSite(); void setRemoteUpdateSite(boolean isRemoteUpdateSite); String getFileSystemUpdatePath(); void setFileSystemUpdatePath(String fileSystemUpdatePath);  }### Answer:
@Test public void testSetUpdateCheckFrequency() { classUnderTest.setUpdateCheckFrequency("test"); assertEquals("test", classUnderTest.getUpdateCheckFrequency()); }
