Konwencja nazewnicza getterów i setterów w JavaBean - ciekawostka

By -

Spotkała mnie ostatnio taka ciekawostka ze strony Javy. Zastanawiałem się dlaczego tworząc zmienne dla wartości tj. uId, dId, pAd gettery i settery wyglądają getuId itd. a nie getUId. Dużo framework'ów radzi sobie z obydwoma stylami, ale niektóre przyjmują wersję tylko pierwszą. Poszukałem troszkę w internecie i dopadłem się do dokumentacji JavaBean. Okazuje się, że jest stworzona konwencja nazewnicza tych funkcji. Zasada jest taka, że zamieniamy pierwszą literę na dużą jeżeli, dwie pierwsze są małe. W innych przypadkach zostawiamy nazwę taką jaka jest. Myślę, że taka ciekawostka może przydać się każdemu.

Why TDD is bad practice?

By -

Did you listen that TDD is bad? What do you think about it? I have my opinion about it! TDD is bad because... We don't have time to write tests first - I think this is a good point. I sometimes don't have time for that. Why? Because I need to do quickly fix on our code and deploy it. In this case I don't have time to create test after wrote production code too. The even worse case is when we have tested this part of our code and test after change doesn't work. I don't like this, because I must read tests and thinking about repair tests for new logic. I really don't like this. I would like to create new test and remove old every time when I have that situation. What's wrong with the test first on this case? Nothing, because if you have time to write tests after create code, you have time to create test before it. Don't you think so? We know how will implement it, but we don't know how testing it - I think a lot of developers have this problem,

How correctly imitate dependencies?

This is continuous of my previous post about why we should imitate our dependencies. I did it not long ago. I though about how do it properly and when I can say that it is correct. Start from test and real dependencies I am starting from the tests. I wrote the simple tests which, I though, are correct. That was my learned about dependencies. I had the good situation that I had some prepared tests before. During the writing test I got a knowledge. A lot of time, I verified what the system return. After it, I got the full automated tests for my dependency. Now, I am sure that dependency works like I think. Like my test use it. I think this is a very good advantage. Extract the interface for communicating The implementation to communicate is implemented and tested. Our test, if you implement it like functionality test, not code test, should show us, how we want to use our dependency. We know what parameters we use, what methods. We know what we want. That is a place where we must extr

Software development using Angular 5 with Spring Boot

Hi everyone. My last the bigger post is about configuration Spring Boot and Angular 5 . After that instruction we have integrated both technology on one app. If you created it you know that development is very hard in this case. We must waiting for build a client and it isn't effective. We can use webpack-dev-server to speed up this process, so this post is just about it. Angular and webpack-dev-server I think I have to explain webpack and webpack-dev-server. The first tools let pack our angular app to one or more files. This files is bundles. It is for improve speed of our app. Why? Because one page application need all files on start by assumption. The better way is load it using only one connection and one file, because establishing connection taking time. This is a few information about webpack, but what is webpack-dev-server? This is the tool. It serve our that files which webpack compiled, but it working on memory, so we have quick result on our browser. This is a amazing
