【框架】Testng用例失败自动重跑（五）

arrow是testng的一个扩展插件，参考arrow的源代码

1.新建一个工程，结果如图：

2.RetryListener.java的代码

package com.netease.qa.testng;

import java.lang.reflect.Constructor;
import java.lang.reflect.Method;
import org.testng.IAnnotationTransformer;
import org.testng.IRetryAnalyzer;
import org.testng.annotations.ITestAnnotation;

/**
 * RetryListener for each test method.
 */
public class RetryListener implements IAnnotationTransformer {
    @Override
    public void transform(ITestAnnotation annotation, Class testClass, Constructor testConstructor, Method testMethod) {
        System.out.println("transform");
        IRetryAnalyzer retry = annotation.getRetryAnalyzer();
        if (retry == null) {
            annotation.setRetryAnalyzer(TestngRetry.class);
        }
    }
}

3.TestngRetry.java的代码

package com.netease.qa.testng;

import org.testng.IRetryAnalyzer;
import org.testng.ITestResult;
import org.testng.Reporter;

import com.netease.qa.testng.utils.ConfigReader;

/**
 * TestNG retry Analyzer.*
 */
public class TestngRetry implements IRetryAnalyzer {
	private int retryCount = 1;
	private static int maxRetryCount;

	static {
		ConfigReader config = ConfigReader.getInstance();
		maxRetryCount = config.getRetryCount();
	}

	@Override
	public boolean retry(ITestResult result) {
		System.out.println("retry");
		if (retryCount <= maxRetryCount) {
			Reporter.setCurrentTestResult(result);
			retryCount++;
			return true;
		}
		return false;
	}

	public static int getMaxRetryCount() {
		return maxRetryCount;
	}

	public int getRetryCount() {
		return retryCount;
	}

}

4.ConfigReader.java的代码

package com.netease.qa.testng.utils;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Enumeration;
import java.util.Properties;

/**
 * Read config.properties file. Get the retrycount,default is 0 if not defined
 */
public class ConfigReader {
	private static ConfigReader cr;
	private int retryCount = 0;
	private String sourceCodeDir = "src";
	private String sourceCodeEncoding = "UTF-8";

	private static final String RETRYCOUNT = "retrycount";
	private static final String SOURCEDIR = "sourcecodedir";
	private static final String SOURCEENCODING = "sourcecodeencoding";
	private static final String CONFIGFILE = "config.properties";

	private ConfigReader() {
		readConfig(CONFIGFILE);
	}

	public static ConfigReader getInstance() {
		if (cr == null) {
			cr = new ConfigReader();
		}
		return cr;
	}

	private void readConfig(String fileName) {
		Properties properties = getConfig(fileName);
		if (properties != null) {
			String sRetryCount = null;

			Enumeration<?> en = properties.propertyNames();
			while (en.hasMoreElements()) {
				String key = (String) en.nextElement();
				if (key.toLowerCase().equals(RETRYCOUNT)) {
					sRetryCount = properties.getProperty(key);
				}
				if (key.toLowerCase().equals(SOURCEDIR)) {
					sourceCodeDir = properties.getProperty(key);
				}
				if (key.toLowerCase().equals(SOURCEENCODING)) {
					sourceCodeEncoding = properties.getProperty(key);
				}
			}
			if (sRetryCount != null) {
				sRetryCount = sRetryCount.trim();
				try {
					retryCount = Integer.parseInt(sRetryCount);
				} catch (final NumberFormatException e) {
					throw new NumberFormatException(
							"Parse " + RETRYCOUNT + " [" + sRetryCount + "] from String to Int Exception");
				}
			}
		}
	}

	public int getRetryCount() {
		return retryCount;
	}

	public String getSourceCodeDir() {
		return this.sourceCodeDir;
	}

	public String getSrouceCodeEncoding() {
		return this.sourceCodeEncoding;
	}

	/**
	 * 
	 * @param propertyFileName
	 * 
	 * @return
	 */
	private Properties getConfig(String propertyFileName) {
		Properties properties = new Properties();
		try {
			properties.load(new FileInputStream(propertyFileName));
		} catch (FileNotFoundException e) {
			properties = null;
		} catch (IOException e) {
			properties = null;
		}
		return properties;
	}
}

5.BaiduTest.java的代码

package com.retry;

import org.testng.annotations.Test;
import static org.testng.Assert.*;

public class BaiduTest {
	@Test
	public void testFalse() {
		assertTrue(false);
	}
}

6.config.properties

#0 means not retry
retrycount=2

7.testng.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="suite_login">
	<listeners>
		<listener class-name="com.netease.qa.testng.RetryListener" />
	</listeners>
	<test name="LoginTest">
		<classes>
			<class name="com.retry.BaiduTest" />
		</classes>
	</test>
</suite>

设置的每次验证都失败，所以会总共运行3次，前两次为skip，后一次为true，运行结果如下

当引入dataProvider后，从第二组数据开始，运行结果与预期的不符，这个还不知道是什么原因，希望有知道的可以一起分享。
