testng 中的 method 乱序问题解决

1、问题说明：
出现问题：

2、解决问题方法
（1）顺序控制方法：目前使用了dependsOnMethods和testng.xml中methods中的include方法顺序控制
结果：偶尔方法执行顺序混乱，大概20%的概率
（2）增加顺序控制方法：priority
结果：无效
（3）增加RePrioritizingListener
结果：有效，暂时没有发现乱序问题

详细解决方法如下：

package tools.testng_Listeners;
import java.lang.reflect.Constructor;
import java.lang.reflect.Method;
import java.util.HashMap;
import org.testng.IAnnotationTransformer;
import org.testng.Reporter;
import org.testng.annotations.ITestAnnotation;
//Listener to fix TestNG Interleaving issue. I had to re-write this as the original example I had did not allow for priority to be manually set on a test level.
public class RePrioritizingListener implements IAnnotationTransformer {
HashMap<Object, Integer> priorityMap = new HashMap<Object, Integer>();
Integer class_priorityCounter = 10000;
// The length of the final priority assigned to each method.
Integer max_testpriorityLength = 4;
@Override
public void transform(ITestAnnotation annotation, Class testClass, Constructor testConstructor, Method testMethod) {
// class of the test method.
Class<?> declaringClass = testMethod.getDeclaringClass();
// Current priority of the test assigned at the test method.
Integer test_priority = annotation.getPriority();
// Current class priority.
Integer current_ClassPriority = priorityMap.get(declaringClass);
if (current_ClassPriority == null) {
current_ClassPriority = class_priorityCounter++;
priorityMap.put(declaringClass, current_ClassPriority);
}
String concatenatedPriority = test_priority.toString();
// Adds 0's to start of this number.
while (concatenatedPriority.length() < max_testpriorityLength) {
concatenatedPriority = "0" + concatenatedPriority;
}
// Concatenates our class counter to the test level priority (example
// for test with a priority of 1: 1000100001; same test class with a
// priority of 2: 1000100002; next class with a priority of 1. 1000200001)
concatenatedPriority = current_ClassPriority.toString() + concatenatedPriority;
//Sets the new priority to the test method.
annotation.setPriority(Integer.parseInt(concatenatedPriority));
String printText = testMethod.getName() + " Priority = " + concatenatedPriority;
Reporter.log(printText);
System.out.println(printText);
}
}
