Code Review Checklist Together With Best Practices Inwards Java

What to review spell doing Code review
Code Review together with Unit testing is i of best evolution practise I ever recommend, strive for together with enforce as much as possible. Even only past times doing code review together with Junit seek out representative ever offering positive resultant it tin endure improved a lot past times constantly learning alongside our mistakes , others mistakes together with past times observing how others are doing it. I ever elbow grease to acquire my code review past times about i alongside to a greater extent than sense together with thus that I tin capture whatever domain specific scenario which has been missed during mean value through procedure together with about alongside less sense together with thus that he tin improve his code readability, conduct hold a 4 pith banking concern correspond together with most importantly I works life that when i explicate my code to about i as component subdivision of code review I myself uncovering many things which tin endure improved or left out.Overall it ever add together something together with improve code character together with trim down bug.

I also review about i else code together with voluntarily conduct hold component subdivision to improve my code agreement powerfulness together with offering assist to others, In this article I volition listing things which I hold off spell doing code review. These are the things which I conduct hold been accumulated over the years but I also hold off forrad to you lot guys to contribute your experience, best practices for code review together with propose how you lot guys do code review. These tips are independent of linguistic communication together with equally, apply to Java, NET or C++ code.

10 points checklist on Code Review

1) Does Code run across the functional requirement: source together with maiden off does code meets all requirements which it should meet, indicate out if anything has been left out.

2) Is in that location whatever Side trial of this change: Sometimes i alter inwards your organization may displace a põrnikas inwards other upstream together with downstream organization together with it’s quite possible that novel developer or anyone who is writing code mightiness non endure available of that dependency. This oft direct related to sense inwards projection together with I works life that the to a greater extent than you lot know nearly the organization together with its environs amend you lot able to figure this out.

3) Concurrency: does code is thread-safe? Does it conduct hold properly synchronized if using shared resource? Does it gratuitous of whatever sort of deadlock or live-lock? Concurrency bugs are difficult to uncovering together with oft surfaces inwards production. Code review is i house where you lot tin uncovering this past times carefully sympathise blueprint together with its implementation.

4) Readability together with maintenance:  do code is readable? Or is it also complicate for some-one consummate new? Always give value to readability as code is non only for this fourth dimension it volition rest in that location for long fourth dimension together with you lot request to read it many times. Another of import facial expression is maintenance as most of software spends 90% fourth dimension on maintenance together with solely 10% fourth dimension on evolution it should endure maintainable together with flexible inwards source place. You tin verify that whether code is configurable or not, hold off for whatever difficult coding, uncovering out what is going to endure changed inwards close time to come etc.

5) Consistency: This is component subdivision of indicate 4 but I conduct hold made it about other split upward indicate because of its importance. This is the best matter you lot tin conduct hold inwards your code which automatically achieves readability. Since many developer together with programmer conduct hold component subdivision inwards projection together with they conduct hold in that location ain mode of coding, it’s inwards best involvement of everybody to shape a coding criterion together with follow it inwards alphabetic character together with spirit. For representative it’s non expert individual using role initialize() together with other is using init() for same sort of operation, proceed you lot code consistent together with it volition hold off better, read better.

6) Performance: Another of import facial expression most of import if you lot are writing high book depression latency electronic trading platform for high-frequency trading which strives for micro minute latency. Carefully monitor which code is going to execute at start-up together with which is going to endure 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 together with exception? It should together with that also alongside predefined together with criterion agency which must endure available together with documented for back upward purpose. I lay this indicate good higher upward on my nautical chart spell doing a review because failing on this indicate tin atomic number 82 your application crash together with non able to recover from fault on other organization or about other component subdivision of the same application.

8) Simplicity: Always consider if in that location is whatever uncomplicated together with elegant option available at-least give a thought together with try. Many times source solution comes inwards remove heed is non best solution together with thus giving about other thought is only worth it.

9) Reuse of existing code: See if the functionality tin endure achieved past times using existing code, the payoff of doing this is that you lot are using tried together with tested code which reduces your QA fourth dimension together with also gives you lot to a greater extent than confidence. Introducing novel libraries innovate a novel dependency. I prefer non to elbow grease anything fancy until it’s absolutely necessary.

10) Unit test: Check whether plenty JUnit seek out cases conduct hold been written together with encompass sufficient per centum of novel code. never permit you lot overstep the code without Junit seek out because developer oft makes excuse of fourth dimension but believe me its worth to write it.

Not terminal but to the lowest degree that lay a comment on your coffee file that past times whom it has been reviewed, what number finds are out together with condition of those. This volition brand the whole procedure official together with ensures that due diligence would endure applied during code review. Its also expert to hold your ain code review checklist or a projection wise code review checklist together with work it every fourth dimension spell doing review. There are together with thus many best practices but I conduct hold solely included those which I follow together with works life interesting but as I had said before this is the expanse which ever needs improvement together with no trunk is perfect on that. So delight contribute your ideas to code review together with effective development.

Enjoy
