katalon中利用java-diff-utils库,实现自动化针对两个文件夹下的同名文件做比较

好的，我明白了。首先，你需要在Katalon中导入java-diff-utils库。你可以在Katalon Studio的“Project Settings”中的“External Libraries”选项卡中添加该库的JAR文件。

然后，你需要编写一个自动化脚本，以比较两个文件夹下的同名文件。以下是一个基本的示例脚本：

import java.io.File;
import java.io.IOException;
import java.nio.charset.StandardCharsets;
import java.nio.file.Files;
import java.util.List;

import difflib.Delta;
import difflib.DiffUtils;
import difflib.Patch;

public class CompareFolders {
    public static void main(String[] args) throws IOException {
        String folderPath1 = "path/to/folder1";
        String folderPath2 = "path/to/folder2";
        
        File folder1 = new File(folderPath1);
        File folder2 = new File(folderPath2);
        
        File[] folder1Files = folder1.listFiles();
        
        for (File file1 : folder1Files) {
            File file2 = new File(folder2.getAbsolutePath() + "/" + file1.getName());
            
            if (file2.exists()) {
                compareFiles(file1, file2);
            }
        }
    }
    
    private static void compareFiles(File file1, File file2) throws IOException {
        List<String> lines1 = Files.readAllLines(file1.toPath(), StandardCharsets.UTF_8);
        List<String> lines2 = Files.readAllLines(file2.toPath(), StandardCharsets.UTF_8);
        
        Patch<String> patch = DiffUtils.diff(lines1, lines2);
        List<Delta<String>> deltas = patch.getDeltas();
        
        if (deltas.size() > 0) {
            System.out.println("Differences found between " + file1.getName() + " and " + file2.getName());
            
            for (Delta<String> delta : deltas) {
                System.out.println(delta);
            }
        } else {
            System.out.println("No differences found between " + file1.getName() + " and " + file2.getName());
        }
    }
}

该脚本将比较两个文件夹下的同名文件，并将输出任何差异。你可以将该脚本集成到Katalon Studio的自动化测试用例中，以便自动执行比较。
