使用Junit比较文本文件

import org.junit.Test;

import java.io.File;
import java.io.FileReader;
import java.io.IOException;

import static org.junit.Assert.assertEquals;

public class TextFileComparatorTest {

    @Test
    public void testCompareTextFiles() throws IOException {
        File file1 = new File("file1.txt");
        File file2 = new File("file2.txt");

        FileReader reader1 = new FileReader(file1);
        FileReader reader2 = new FileReader(file2);

        int ch1, ch2;
        while ((ch1 = reader1.read()) != -1) {
            ch2 = reader2.read();
            assertEquals("Files are not equal", ch1, ch2);
        }

        reader1.close();
        reader2.close();
    }
}
