好的,所以我有一个这样的课
public class Calculator {
@Test(dataProvider = "dp")
public void add(int a,int b) {
System.out.println("Invoked add: a,b" + a + "," + b);
}
@DataProvider(name = "dp")
public Object[][] createData(ITestContext ctx) {
return new Object[][] { new Object[] { 1,2 },new Object[] { 2,3 } };
}
当测试运行时,它将运行add方法两次.我想根据其输入跟踪每个添加的调用.所以说,add被调用1,2作为输入,那就是一个唯一的调用.如果失败,我想将此信息存储到具有调用ID的数据库.
使用testng如何实现？所有的监听器(methodinvocationlistener等)似乎没有提供唯一标识方法运行的上下文.是的,他们确实让你看到参数,但是我无法跟踪各个参数.那么,我以某种方式将我自己的唯一参数注入到结果对象中并从中跟踪呢？
UPDATE
我正在添加改进的代码,以帮助更好地理解上下文.
这是我的testng.xml
<suite name="Default Suite">
<test name="test">
<classes>
<class name="com.test.testng.Calculator">
<methods>
<include name="add">
<parameter name="data-id" value="1"/>
</include> <!-- add -->
<include name="add">
<parameter name="data-id" value="2"/>
</include> <!-- add -->
<include name="subtract">
<parameter name="data-id" value="3"/>
</include> <!-- subtract -->
</methods>
</class> <!-- com.test.testng.Calculator -->
</classes>
</test> <!-- test -->
</suite> <!-- Default Suite -->
public class Calculator {
@Test(dataProvider = "dp")
public void add(int first,int second) {
System.out.println("invoked add");
}
@Test(dataProvider = "dp")
public void subtract(int first,int second) {
System.out.println("invoked subtract");
}
@DataProvider(name = "dp")
public Object[][] createData(Method m,ITestContext ctx) {
Object[][] data = new Object[][] { new Object[] { 1,3 },new Object[] { 3,4 } };
for (XmlClass test : ctx.getCurrentXmlTest().getXmlClasses()) {
for (XmlInclude method : test.getIncludedMethods()) {
if (method.getName().equals(m.getName()))
int key = Integer.parseInt(method.getAllParameters().get("data-id"));
return new Object[][] { data[key - 1] };
}
}
return null ;
}
}
我预计,添加运行两次,一次以1,2为输入,另一次为2,3输入.类似地,用3,4减去输入.但是,我看到的是这样的 –
[SuiteRunner] Created 1 TestRunners

我需要根据我将从testng xml发送的特殊参数为每个方法提供数据.我该如何实现？
解决方法
要实现这一点,您可以在testng.xml中定义不同的测试用例,如下所示：
<suite name="Default Suite">
<test name="test">
<classes>
<class name="com.test.testng.Calculator">
<methods>
<include name="add">
<parameter name="data-id" value="1"/>
</include> <!-- add -->
<include name="subtract">
<parameter name="data-id" value="3"/>
</include> <!-- subtract -->
</methods>
</class> <!-- com.test.testng.Calculator -->
</classes>
</test> <!-- test -->
<test name="test2">
<classes>
<class name="com.test.testng.Calculator">
<methods>
<include name="add">
<parameter name="data-id" value="2"/>
</include> <!-- add -->
</methods>
</class> <!-- com.test.testng.Calculator -->
</classes>
</test> <!-- test -->
</suite> <!-- Default Suite -->
package com.test.testng;
import java.lang.reflect.Method;
import org.testng.ITestContext;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
import org.testng.xml.XmlClass;
import org.testng.xml.XmlInclude;
public class Calculator {
@Test(dataProvider = "dp")
public void add(int first,4 } };
for (XmlClass test : ctx.getCurrentXmlTest().getXmlClasses()) {
for (XmlInclude method : test.getIncludedMethods()) {
if (method.getName().equals(m.getName())) {
int key = Integer.parseInt(method.getAllParameters().get("data-id"));
System.out.println("Running method " + m.getName() + " with data-id: " + key);
return new Object[][] { data[key - 1] };
}
}
}
return null ;
}
}
运行这个xml作为testng套件(使用eclipse插件)显示：
[TestNG] Running: /Users/fhernandez/Documents/workspaceTest/testNg-test/src/test/resources/testng.xml Running method add with data-id: 1 invoked add Running method subtract with data-id: 3 invoked subtract Running method add with data-id: 2 invoked add =============================================== Default Suite Total tests run: 3,Failures: 0,Skips: 0 ===============================================
如果我理解你的要求,你可以实现它.
实现这一点的另一种方法是在测试类之前放置一个方面或代理,并且检查方法调用,在此方面/代理中实现您的需求.
UPDATE
我添加一个监听器到计算器
@Listeners(Listener.class) public class Calculator
监听器如下所示
package com.test.testng;
import java.util.Arrays;
import org.testng.IInvokedMethod;
import org.testng.IInvokedMethodListener;
import org.testng.ITestResult;
import org.testng.xml.XmlClass;
import org.testng.xml.XmlInclude;
public class Listener implements IInvokedMethodListener {
public void afterInvocation(IInvokedMethod method,ITestResult itr) {
// TODO implements
}
public void beforeInvocation(IInvokedMethod method,ITestResult testResult) {
// Parameters value
System.out.println("Parameters invocation value for method " + method.getTestMethod().getMethodName());
Arrays.asList(testResult.getParameters()).stream().forEach(System.out::println);
// get data-id
for (XmlClass test : testResult.getTestContext().getCurrentXmlTest().getXmlClasses()) {
for (XmlInclude met : test.getIncludedMethods()) {
if (met.getName().equals(method.getTestMethod().getMethodName())) {
int key = Integer.parseInt(met.getAllParameters().get("data-id"));
System.out.println("listener: Running method " + method.getTestMethod().getMethodName() + " with data-id: " + key);
}
}
}
}
}
beforeInvocation中的代码显示参数调用值和data-id,这是输出
[TestNG] Running: /Users/fhernandez/Documents/workspaceTest/testNg-test/src/test/resources/testng.xml Running method add with data-id: 1 Parameters invocation value for method add 1 2 listener: Running method add with data-id: 1 invoked add Running method subtract with data-id: 3 Parameters invocation value for method subtract 3 4 listener: Running method subtract with data-id: 3 invoked subtract Running method add with data-id: 2 Parameters invocation value for method add 2 3 listener: Running method add with data-id: 2 invoked add =============================================== Default Suite Total tests run: 3,Skips: 0 ===============================================
