Java combined with testng, data-driven examples of data sources using XML

TestNG is very powerful, @dataprovider can be used to do data-driven, data source files can be excel,xml,yaml, even can be txt text. In this case, take XML as an example:

Note: The return value type of the @DataProvider can only be object[][] and iterator<object>[]

Testdata.xml:

<?XML version= "1.0" encoding= "UTF-8"?><Data><TestMethod1><Input>1</Input><button>2</button></TestMethod1><TestMethod1><Input>3</Input><button>4</button></TestMethod1><Testmethod2><Input>3</Input><button>4</button></Testmethod2><Testmethod3><Input>3</Input><button>4</button></testmethod3> " Span style= "COLOR: #0000ff" ><testmethod4> <input>3</input> <button>4</button> </testmethod4></data>      

Parse the Xml,parserxml.java file with dom4j:

PackageCom.test;ImportJava.io.File;ImportJava.util.ArrayList;ImportJava.util.HashMap;ImportJava.util.Iterator;ImportJava.util.List;ImportJava.util.Map;ImportOrg.dom4j.Document;ImportOrg.dom4j.DocumentException;ImportOrg.dom4j.Element;ImportOrg.dom4j.io.SAXReader;PublicClassParserxml {PublicList parser3xml (String fileName) {File Inputxml =NewFile (FileName); List list=NewArrayList ();int count = 1; Saxreader Saxreader =NewSaxreader ();Try{Document document =Saxreader.read (Inputxml); Element employees =Document.getrootelement ();For (Iterator i = employees.elementiterator (); I.hasnext ();) {Element employee = (Element) I.next (); Map map = new HashMap (); Map Tempmap = new HashMap (); For (Iterator j = employee.elementiterator (); J.hasnext ();) {element node = (Element) J.next (); Tempmap.put (Node.getname (), Node.gettext ());} map.put (Employee.getname (), TEMPMAP); List.add (map); }} catch (Documentexception e) {System.out.println (E.getmessage ());} return list;}}             

The parsed list is then converted to object[][] type data, and is combined in @dataprovider.

Testdata.java file:

PackageCom.test;ImportJava.io.File;ImportJava.lang.reflect.Method;ImportJava.util.ArrayList;ImportJava.util.HashMap;ImportJava.util.Iterator;ImportJava.util.List;ImportJava.util.Map;ImportOrg.testng.annotations.DataProvider;PublicClassTestData {PrivateList l;PublicTestData () {This. Getxmldata (); }PublicvoidGetxmldata () {Parserxml p =NewParserxml (); L = P.parser3xml (New File ("Src/com/test/testdata.xml"). GetAbsolutePath ()); } @DataProviderPublicObject[][] Providermethod (method) {list<map<string, string>> result =New Arraylist<map<string, string>> (); for (int i = 0; i < l.size (); I++ (MAP) l.get (i); if (M.containskey (Method.getname ())) {map<string, string> DM = (map<string, String>new Object[result.size () []; for (int i=0; i<result.size (); i++ ) {Files[i] = new object[]{ Result.get (i)}; } return files;}}       

Test the test file again:

Testdataprovider.java file:

PackageCom.test;ImportJava.util.Map;Import org.testng.annotations.*;PublicClass TestdataproviderExtendsTestData {@Test (dataprovider= "Providermethod")Publicvoid TestMethod1 (map<?,? >param) {System.out.println ("Method1 Received:" +param.get ("input")); } @Test (dataprovider= "Providermethod") public void Testmethod2 (map<?,? > param) { System.out.println ("Method2 Received:" +param.get ("input"));} @Test (dataprovider= "Providermethod") public void testmethod3 (map<?,? > param) { System.out.println ("Method3 Received:" +param.get ("input"));} @Test public void testmethod4 () {System.out.println ("method4 received:4");}}    

Let's go back and analyze the XML file, there are two TESTMETHOD1 nodes, one for each of the TESTMETHOD2,TESTMETHOD3,TESTMETHOD4 nodes, and in the Testdataprovider.java file, define the TESTMETHOD1,TESTMETHOD2,TESTMETHOD3,TESTMETHOD4 four test functions, and TESTMETHOD4 does not use Dataprovider, So the running result should be testmethod1 run two times, testmethod2,testmethod3,testmethod4 each run again, the results are as follows:

Method1 received:1method1 received:3method2 received:3method3 received:3method4 received:4 Passed:testmethod1 ({input=1, button=2}) passed:testmethod1 ({input=3, button=4}) passed:testmethod2 ({input= 3, Button=4}) passed:testmethod3 ({input=3, button=4
