Code Review Checklist Too Best Practices Inwards Java
What to review piece doing Code review
Code Review too Unit testing is 1 of best evolution exercise I ever recommend, strive for too enforce as much as possible. Even but yesteryear doing code review too Junit essay instance ever offering positive final result it tin terminate survive improved a lot yesteryear constantly learning amongst our mistakes , others mistakes too yesteryear observing how others are doing it. I ever endeavour to acquire my code review yesteryear or too thus 1 amongst to a greater extent than sense too thus that I tin terminate capture whatever domain specific scenario which has been missed during intend through procedure too or too thus amongst less sense too thus that he tin terminate improve his code readability, guide hold a 4 catch depository fiscal establishment gibe too most importantly I constitute that when i explicate my code to or too thus 1 as constituent of code review I myself discovery many things which tin terminate survive improved or left out.Overall it ever add together something too improve code character too cut bug.

I also review or too thus 1 else code too voluntarily accept constituent to improve my code agreement powerfulness too offering assist to others, In this article I volition listing things which I expect piece doing code review. These are the things which I guide hold been accumulated over the years but I also expect forwards to y'all guys to contribute your experience, best practices for code review too propose how y'all guys do code review. These tips are independent of linguistic communication too equally, apply to Java, NET or C++ code.10 points checklist on Code Review
1) Does Code come across the functional requirement: offset too firstly does code meets all requirements which it should meet, indicate out if anything has been left out.
2) Is at that spot whatever Side upshot of this change: Sometimes 1 alter inwards your arrangement may movement a põrnikas inwards other upstream too downstream arrangement too it’s quite possible that novel developer or anyone who is writing code mightiness non survive available of that dependency. This oft straight related to sense inwards projection too I constitute that the to a greater extent than y'all know virtually the arrangement too its surroundings meliorate y'all able to figure this out.
3) Concurrency: does code is thread-safe? Does it guide hold properly synchronized if using shared resource? Does it gratis of whatever form of deadlock or live-lock? Concurrency bugs are difficult to discovery too oft surfaces inwards production. Code review is 1 house where y'all tin terminate discovery this yesteryear carefully empathize pattern too its implementation.
4) Readability too maintenance: do code is readable? Or is it likewise complicate for some-one consummate new? Always give value to readability as code is non but for this fourth dimension it volition rest at that spot for long fourth dimension too y'all involve to read it many times. Another of import facial expression is maintenance as most of software spends 90% fourth dimension on maintenance too exclusively 10% fourth dimension on evolution it should survive maintainable too flexible inwards offset place. You tin terminate verify that whether code is configurable or not, expect for whatever difficult coding, discovery out what is going to survive changed inwards close hereafter etc.
5) Consistency: This is constituent of indicate 4 but I guide hold made it or too thus other split indicate because of its importance. This is the best affair y'all tin terminate guide hold inwards your code which automatically achieves readability. Since many developer too programmer accept constituent inwards projection too they guide hold at that spot ain agency of coding, it’s inwards best involvement of everybody to cast a coding criterion too follow it inwards missive of the alphabet too spirit. For instance it’s non practiced person using business office initialize() too other is using init() for same form of operation, dice along y'all code consistent too it volition expect better, read better.
6) Performance: Another of import facial expression most of import if y'all are writing high book depression latency electronic trading platform for high-frequency trading which strives for micro instant latency. Carefully monitor which code is going to execute at start-up too which is going to survive executed inwards a loop or multiple times optimize the code which is going to execute to a greater extent than often.
7) Exception handling: Ask does code handles bad input too exception? It should too that likewise amongst predefined too criterion agency which must survive available too documented for back upwards purpose. I lay this indicate good higher upwards on my nautical chart piece doing a review because failing on this indicate tin terminate atomic number 82 your application crash too non able to recover from fault on other arrangement or or too thus other constituent of the same application.
8) Simplicity: Always consider if at that spot is whatever unproblematic too elegant option available at-least give a thought too try. Many times offset solution comes inwards take away heed is non best solution too thus giving or too thus other thought is but worth it.
9) Reuse of existing code: See if the functionality tin terminate survive achieved yesteryear using existing code, the payoff of doing this is that y'all are using tried too tested code which reduces your QA fourth dimension too also gives y'all to a greater extent than confidence. Introducing novel libraries innovate a novel dependency. I prefer non to endeavour anything fancy until it’s absolutely necessary.
10) Unit test: Check whether plenty JUnit essay cases guide hold been written too embrace sufficient percent of novel code. never allow y'all transcend the code without Junit essay because developer oft makes excuse of fourth dimension but believe me its worth to write it.
Not final but to the lowest degree that lay a comment on your coffee file that yesteryear whom it has been reviewed, what number finds are out too condition of those. This volition brand the whole procedure official too ensures that due diligence would survive applied during code review. Its also practiced to hold your ain code review checklist or a projection wise code review checklist too utilization it every fourth dimension piece doing review. There are too thus many best practices but I guide hold exclusively included those which I follow too constitute interesting but as I had said before this is the expanse which ever needs improvement too no trunk is perfect on that. So delight contribute your ideas to code review too effective development. Enjoy
