如何为outputStream.write IO IOException编写junit测试

import org.junit.Test;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import static org.junit.Assert.assertEquals;

@Test
public void testWriteIOException() {
    // 测试代码将在这里编写
}

OutputStream outputStream = new OutputStream() {
    @Override
    public void write(int b) throws IOException {
        throw new IOException("Simulated IOException");
    }
};

try {
    outputStream.write(0); // 调用被测试的方法
} catch (IOException e) {
    // 在这里处理IOException
}

assertEquals("Simulated IOException", e.getMessage());

import org.junit.Test;
import java.io.IOException;
import java.io.OutputStream;
import static org.junit.Assert.assertEquals;

public class MyOutputStreamTest {

    @Test
    public void testWriteIOException() {
        OutputStream outputStream = new OutputStream() {
            @Override
            public void write(int b) throws IOException {
                throw new IOException("Simulated IOException");
            }
        };

        try {
            outputStream.write(0);
        } catch (IOException e) {
            assertEquals("Simulated IOException", e.getMessage());
        }
    }
}
