在gradle junit测试中使用可执行文件

test {
    // 设置测试任务的classpath，包括可执行文件所在的目录
    classpath += files('executables')

    // 在测试之前，将可执行文件复制到测试类所在的目录
    doFirst {
        copy {
            from 'executables'
            into sourceSets.test.output.classesDirs.singleFile
        }
    }
}

import org.junit.Test;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class ExecutableTest {

    @Test
    public void testExecutable() throws IOException {
        ProcessBuilder processBuilder = new ProcessBuilder("executable_name", "arg1", "arg2");
        processBuilder.directory(new File("build/classes/java/test")); // 设置可执行文件所在的目录
        Process process = processBuilder.start();

        BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
        String line;
        while ((line = reader.readLine()) != null) {
            System.out.println(line);
        }

        process.destroy();
    }
}
