java 与testng利用XML做数据源的数据驱动示例详解
java 与testng利用XML做数据源的数据驱动示例详解
testng的功能很强大,利用@DataProvider可以做数据驱动,数据源文件可以是EXCEL,XML,YAML,甚至可以是TXT文本。在这以XML为例:
备注:@DataProvider的返回值类型只能是Object[][]与Iterator
TestData.xml:
1
3
3
3
3
<button>4
处用DOM4J解析XML,ParserXml.java文件:
package com.test;
import java.io.File;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.http://dom4j.io.SAXReader;
public class ParserXml {
public List parser3Xml(StringEgOGW fileName) {
File inputXml = new File(fileName);
List list=new ArrayList();
int count = 1;
SAXReader saxReader = new SAXReader();
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;
}
}
然后把解析出来的list转换成Object[][]类型的数据,且结合在@DataProvider中。
TestData.java文件:
package com.test;
import java.io.File;
import java.lang.reflect.Method;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import org.testng.annotations.DataProvider;
public class TestData {
private List l;
public TestData() {
this.getXmlData();
}
public void getXmlData(){
ParserXml p = new ParserXml();
l = p.parser3Xml(new File("src/com/test/TestData.xml").getAbsolutePath());
}
@DataProvider
public Object[][] providerMethod(Method method){
List
for (int i = 0; i < l.size(); i++) {
Map m = (Map) l.get(i);
if(m.containsKey(method.getName())){
Map
result.add(dm);
}
}
Object[][] files = new Object[result.size()][];
for(int i=0; i files[i] = new Object[]{result.get(i)}; } return files; } } 再通过测试文件来测试一下: TestDataProvider.java文件: package com.test; import java.util.Map; import org.testng.annotations.*; public class TestDataProvider extends TestData { @Test(dataProvider="providerMethod") public void 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"); } } 我们再回过头来分析一下XML文件,有两个testmethod1结点,testmethod2,testmethod3,testmethod4结点各一个,在TestDataProvider.java文件中,定义了testmethod1,testmethod2,testmethod3,testmethod4四个测试函数,且testmethod4没有用到dataProvider,所以运行结果最后应该是testmethod1运行两遍,testmethod2,testmethod3,testmethod4各运行一遍,结果如下: method1 received:1 method1 received:3 method2 received:3 method3 received:3 method4 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}) PASSED: testmethod4 =============================================== Default test Tests run: 5, Failures: 0, Skips: 0 =============================================== 也就是说通过这种方式,只需要把测试函数先写好,然后在XML文件中定义好数据就行了,就能控制函数是否运行,运行次数且运行的数据。 OK,Let's try..... 感谢阅读,希望能帮助到大家,谢谢大家对本站的支持!
files[i] = new Object[]{result.get(i)};
}
return files;
}
}
再通过测试文件来测试一下:
TestDataProvider.java文件:
package com.test;
import java.util.Map;
import org.testng.annotations.*;
public class TestDataProvider extends TestData {
@Test(dataProvider="providerMethod")
public void 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");
}
}
我们再回过头来分析一下XML文件,有两个testmethod1结点,testmethod2,testmethod3,testmethod4结点各一个,在TestDataProvider.java文件中,定义了testmethod1,testmethod2,testmethod3,testmethod4四个测试函数,且testmethod4没有用到dataProvider,所以运行结果最后应该是testmethod1运行两遍,testmethod2,testmethod3,testmethod4各运行一遍,结果如下:
method1 received:1
method1 received:3
method2 received:3
method3 received:3
method4 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})
PASSED: testmethod4
===============================================
Default test
Tests run: 5, Failures: 0, Skips: 0
===============================================
也就是说通过这种方式,只需要把测试函数先写好,然后在XML文件中定义好数据就行了,就能控制函数是否运行,运行次数且运行的数据。
OK,Let's try.....
