Membuat pengujian unit Java

Membuat pengujian unit untuk kode Java lama

Anda dapat membuat kueri model secara langsung dan menguji hasil yang ditampilkan saat menggunakan parameter value yang berbeda dengan Konsol Cloud, atau dengan memanggil Vertex AI API secara langsung.

Petunjuk sistem

Anda adalah developer Java yang mahir dan ahli dalam pengembangan Berbasis Pengujian. Sasaran utama Anda adalah menulis kode Java yang rapi, efisien, dan dapat dikelola serta memastikan bahwa semua fungsi diuji secara menyeluruh.

Perintah Freeform

Saya adalah developer Java dan telah mengikuti metodologi pengembangan berbasis pengujian. Saya memiliki kode berikut yang digunakan untuk mengoperasikan robot, yang akan segera saya faktorkan ulang untuk menambahkan fungsi pembersihan. Sebagai cara untuk memastikan bahwa saya tidak merusak apa pun selama proses pemfaktoran ulang dan untuk memahami perilaku kode, saya ingin menambahkan beberapa pengujian karakterisasi ke kode yang ada.

  • Lihat kode berikut dan tulis pengujian unit menggunakan JUnit 4 untuk metode di class RoboCleaner.
  • Pastikan Anda memberikan nama yang bermakna untuk pengujian, dan mencakup kasus ekstrem apa pun.
public class RoboCleaner {
    int x, y;
    Direction direction;

    public RoboCleaner(int initialX, int initialY, Direction initialDirection) {
        this.x = initialX;
        this.y = initialY;
        this.direction = initialDirection;
    }

    public void moveForward(int steps) {
        switch (direction) {
            case NORTH:
                y += steps;
                break;
            case SOUTH:
                y -= steps;
                break;
            case EAST:
                x += steps;
                break;
            case WEST:
                x -= steps;
                break;
        }
    }

    public void turnLeft() {
        direction = direction.turnLeft();
    }

    public void turnRight() {
        direction = direction.turnRight();
    }

    public String getPosition() {
        return String.format("Position: (%d, %d), Facing: %s", x, y, direction);
    }

    public enum Direction {
        NORTH, EAST, SOUTH, WEST;

        private static final Direction[] leftTurns = {WEST, NORTH, EAST, SOUTH};
        private static final Direction[] rightTurns = {EAST, SOUTH, WEST, NORTH};

        public Direction turnLeft() {
            return leftTurns[ordinal()];
        }

        public Direction turnRight() {
            return rightTurns[ordinal()];
        }
    }
}
