### Question:
AnchorDefinition { public String getId() { return ID; } AnchorDefinition(Path file, String anchorName, int lineNum); String getAnchorName(); Path getSrcFile(); String getId(); int getLineNumber(); String getHelpPath(); @Override String toString();  }### Answer:
@Test public void testFileWithoutAnchor() { Path fullPath = Paths.get("/fake/full/path/help/topics/TopicName/HelpFilename.html"); AnchorDefinition def = new AnchorDefinition(fullPath, null, 1); assertEquals("TopicName_HelpFilename", def.getId()); }
@Test public void testFileInHelpTopicDir() { Path fullPath = Paths.get("/fake/full/path/help/topics/TopicName/HelpFilename.html"); AnchorDefinition def = new AnchorDefinition(fullPath, "anchor_1", 1); assertEquals("TopicName_anchor_1", def.getId()); }
@Test public void testFileInHelpTopicJar() { Path fullPath = Paths.get("/help/topics/TopicName/HelpFilename.html"); AnchorDefinition def = new AnchorDefinition(fullPath, "anchor_1", 1); assertEquals("TopicName_anchor_1", def.getId()); }
