### Question:
SahiScript { public static String modifyFunctionNames(String unmodified) { unmodified = stripSahiFromFunctionNames(unmodified); return REG_EXP_FOR_ADDING.matcher(unmodified).replaceAll("_sahi.$1$2"); } SahiScript(String filePath, ArrayList<String> parents, String scriptName); String jsString(); String modifiedScript(); String getDebugInfo(int lineNumber); String getLineDebugInfo(int lineNumber); static boolean lineStartsWithActionKeyword(String line); static String modifySingleLine(String line); static String modifyFunctionNames(String unmodified); static String stripSahiFromFunctionNames(String unmodified); static ArrayList<String> getActionKeyWords(); static ArrayList<String> getKeyWords(); String modifyCondition(String s, int lineNumber); String getScriptName(); String getOriginal(); String getOriginalInHTML(); String getFilePath(); String getBrowserJS(); void addIncludeInfo(SahiScript included); String getBrowserJSWithLineNumbers();  }### Answer:
@Test public void testModifyFunctionNames() { assertEquals("_sahi._setGlobal(", TestScript.modifyFunctionNames("_setGlobal(")); assertEquals("_insert (", TestScript.modifyFunctionNames("_insert (")); assertEquals("_sahi._setValue (", TestScript.modifyFunctionNames("__setValue (")); }
