The tests are all good.

The tests in source/simple_cipher.d expect the class name to be VigenereCipher. The last test constructs a VigenereCipher without supplying a key, to test random key generation.

The solution currently in source/simple_cipher.d passes all the tests. Bu the solution currently in example/simple_cipher.d does not: a different class name is used, and the constructor does not allow the key to be omitted.

Let's delete the current contents of example/simple_cipher.d, and instead use the current first 75 lines of source/simple_cipher.d as our new example/simple_cipher.d

In source/simple_cipher.d we can have

import ...

class VigenereCipher {
    this(string key = "") {
        // implement this function
    }

    string encode(string plaintext) {
        // implement this function
    }

    string decode(string ciphertext) {
        // implement this function
    }

    string getKey() {
        // implement this function
    }
}

unittest {
...

We can check that the example solution passes by running

$ bin/test-exercise  exercises/practice/simple-cipher

The robot-simulator exercise has a similar structure:

example/robot_simulator.d has a working solution.

source/robot_simulator.d has

import ...

class RobotSimulator
{
    this(int x, int y, string direction)
    {
        // implement this function
    }

    void move(string commands)
    {
        // implement this function
    }
}

unittest
...

If you are interested in adding another exercise after this, you might find the bin/add-practice-exercise script helpful.

For example,

$ bin/add-practice-exercise -a Narkunan -d 6 rail-fence-cipher

will update the config.json files for you, and copy the instructions.

Many thanks for contributing this exercise.

I'm not sure why you removed generateKey() and the last unit test.

Many thanks for contributing this exercise.

I'm not sure why you removed generateKey() and the last unit test.

Thanks for accepting my PR

I thought they are out of scope because mostly we will concern about encryption and decryption That's why I removed
