我正在使用dataprovider方法和测试方法（在测试方法中使用ITestContext参数）。一个简化的例子如下：
@DataProvider(name="Dataprovider")
public Object[][] dataprovider(){
return new Object[][]{{1},{2,},{3}};
}
@Test(dataProvider="Dataprovider")
public void test(int data, ITestContext itx){
System.out.println(data);
org.testng.Assert.assertEquals(data, 3);
}
我的重试类和RetryListener类如下：
public class RetryListener implements IAnnotationTransformer {
@Override
public void transform(ITestAnnotation testannotation, Class testClass,
Constructor testConstructor, Method testMethod) {
IRetryAnalyzer retry = testannotation.getRetryAnalyzer();
if (retry == null) {
testannotation.setRetryAnalyzer(Retry.class);
}
}
}
public class Retry implements IRetryAnalyzer {
private static int retryCount = 0;
private int maxRetryCount = 1;
// Below method returns 'true' if the test method has to be retried else 'false'
//and it takes the 'Result' as parameter of the test method that just ran
public boolean retry(ITestResult result) {
if (retryCount < maxRetryCount) {
System.out.println("Retrying test " + result.getName() + " with status "
+ getResultStatusName(result.getStatus()) + " for the " + (retryCount+1) + " time(s).");
retryCount++;
return true;
}
retryCount = 0;
return false;
}
public String getResultStatusName(int status) {
String resultName = null;
if(status==1)
resultName = "SUCCESS";
if(status==2)
resultName = "FAILURE";
if(status==3)
resultName = "SKIP";
return resultName;
}
}
预期：当测试失败时，TestNG会调用重试，然后数据提供者应该将相同的值返回给测试方法。
观察：Dataprovider返回相同的值，但测试方法没有运行，重试终止，下一次测试开始（dataprovider现在将返回新值）
但是我的重试没有进入测试方法（它不期望测试方法的（int数据，ITestContext itx））。如果我删除了ITestContext，则重试有效。
ITestContext是维护测试用例上下文的必要条件。那么如何执行重试以及将ITestContext保留在测试方法中。
答案 0 :(得分：0)
在由数据提供程序提供支持的@Test方法中，我认为很难将ITestContext作为显式参数并期望它由TestNG注入，因为TestNG不知道如何注入它（特别是在哪个位置）。
请查看以下内容是否适合您（如果您注意到，我现在明确地通过数据提供商传递ITestContext）
import org.testng.IRetryAnalyzer;
import org.testng.ITestContext;
import org.testng.ITestResult;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
public class RetryWithDataProvider {
@DataProvider(name = "Dataprovider")
public Object[][] dataprovider(ITestContext ctx) {
return new Object[][]{{1, ctx}, {2, ctx}, {3, ctx}};
}
@Test(dataProvider = "Dataprovider", retryAnalyzer = Retry.class)
public void test(int data, ITestContext itx) {
System.out.println(data);
System.out.println("Current Test name is : " + itx.getName());
org.testng.Assert.assertEquals(data, 3);
}
public static class Retry implements IRetryAnalyzer {
private static int retryCount = 0;
private int maxRetryCount = 1;
public boolean retry(ITestResult result) {
if (retryCount < maxRetryCount) {
System.out.println("Retrying test " + result.getName() + " with status "
+ getResultStatusName(result.getStatus()) + " for the " + (retryCount + 1) + " time(s).");
retryCount++;
return true;
}
retryCount = 0;
return false;
}
String getResultStatusName(int status) {
String resultName = null;
if (status == 1)
resultName = "SUCCESS";
if (status == 2)
resultName = "FAILURE";
if (status == 3)
resultName = "SKIP";
return resultName;
}
}
}
这是我的控制台输出
