There is a big chance that not every Neptun owner school will get/install the latest version of the official
Neptun to their servers so it will cause some problems here.

Ideas

Support only (the latest) one build

- Not flexible (should monitor the release cycle of the official app because maybe this is good enought™)
- There is a big chance that we can not support every School when a new release came up (which is a huge problem)

+ Easiest way to maintain the app
+ No need NuGet package for each School

Support only the latest two builds

- Can cause ugly codebase
For eg.:

class ...Deserializer
{
    public int ..Count(string sourceCode)
    {
        if (OfficialApp.BuildNumber == 455)
        {
            RunLatestDeserializer(sourceCode);
        }
        else if (OfficialApp.BuildNumber == 454)
        {
            RunSecondLatestDeserializer(sourCode);
        }
    }
}

- There is a small chance that we can not support every School when a new release came up (which is a huge problem)

+ Bit flexible
+ No need NuGet package for each School

Support every build

- Lot of Google Play / AppStore / Microsoft Store updates (caused by the lot of School NuGet dependency)
- More complex App

                            School NuGet        NeptunPro NuGet
                         ←    ELTE        ←   Neptun Build 455
    Container App        ←    OE          ←   Neptun Build 454
                         ←    ...

- Dependency Hell?
- Maybe this is not even possible (or maybe yes?)

+ Cleanest solution for the problem

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>()
        {
            ...
        };
    }
}

...

[TestMethod]
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
    ...
}

[DataSource]
[DataRow(expexted, actual)]
private void CompareSpecificMessage(Message expected, Message actual)
{
    Assert.AreEqual(expected, actual);
}

Scrape data from TudásBázis.SuliNet.hu and store it.

Scrape neptun.org for new schools every day.

Display a cup with a rate:

4.99

This is not my idea.

One of my fried told me that (s)he scheduled his/her classes to not meet with certain people. 😄

Villamosságtan is a subject with a lot of failing student on OE.
Maybe with some kind of students developed full note (version controlled .md or gist file from A to Z will help.

Of course, maybe only OE uses Moodle but with some abstraction this can be useful for every School.
