Implement Regression tests

Live calls to the webpage

• Compare the hard coded object (refreshed before started the tests) with the parsed response;
• Call modification endpoints and validate that the endpoint still exists and change what is should change (for eg.: number of messages in the InBox, add/edit/delete phone number(s), etc.).

Example:

class User : Student
{
    public string Name { get; }
    public int BankAccountBalance { get; }
    public ISchool School { get; }
    public List<Message> Messages { get; }



    public User()
    {
        Name = "Tom PoLáKoSz";
        BankAccountBalance = 20000;
        School = new ObudaiEgyetem();
        Messages = new List<Message>()
        {
            ...
        };
    }
}

...

public async void SampleRegressionTests()
{
    _user = new User();

    var loginPage = new LoginPage(_user.School);
    var messagesPage = new MessagesPage(_user.School);

    int maxTryNumber = await loginPage.GetMaxTryNumber();
    await loginPage.LogIn(_user);

    List<Message> messages = await messagesPage.InBox();
    Message specificMessage = await messagesPage.GetMessage(messages[0]);

    CompareSpecificMessage(_user.Messages[0], specificMessage);// maybe this is not valid
    ...
