这是我简单的JUnit参数化测试，我使用testdata解析csv，并尝试将其提供给Parametrized.Parameters，但是当我运行它时，我的测试与package com.mypkg;
import java.awt.AlphaComposite;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.File;
import java.net.URL;
import javax.imageio.ImageIO;
import org.imgscalr.Scalr;
public class Overlay {
public static void main(String args[]){
URL url = null;
try{
//The gray image used for overlay
url = new URL("https://hoursofidleness.files.wordpress.com/2012/06/gray-card.jpg");
BufferedImage img1 = ImageIO.read(url);
//The original image which I want to gray out
url = new URL("http://www.staywallpaper.com/wp-content/uploads/2016/01/Colorful-Wallpaper-HD-pictures-STAY015.jpg");
BufferedImage img2 = ImageIO.read(url);
BufferedImage reImg2 = Scalr.resize(img2, Scalr.Method.BALANCED, Scalr.Mode.FIT_EXACT, 150, 150);
//Make the gray image, which is used as the overlay, translucent
BufferedImage transparent = new BufferedImage(img1.getWidth(), img1.getHeight(),BufferedImage.TRANSLUCENT);
Graphics2D g2d = transparent.createGraphics();
g2d.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, (float) 0.50));
g2d.drawImage(img1, null, 0, 0);
g2d.dispose();
BufferedImage reImg1 = Scalr.resize(transparent, Scalr.Method.BALANCED, Scalr.Mode.FIT_EXACT, 150, 150);
//Merge both images
BufferedImage result = new BufferedImage(150, 150, BufferedImage.TYPE_INT_ARGB);
Graphics2D g = result.createGraphics();
g.drawImage(reImg2, 0, 0, null);
g.drawImage(reImg1, 0, 0, null);
g.dispose();
ImageIO.write(result,"png",new File("/result.png"));
} catch(Exception e){
e.printStackTrace();
}
}
}
崩溃
