Code Review Checklist In Addition To Best Practices Inwards Java

What to review spell doing Code review
Code Review together with Unit testing is 1 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 attempt instance ever offering positive final result it tin hold upwards improved a lot past times constantly learning amongst our mistakes , others mistakes together with past times observing how others are doing it. I ever effort to acquire my code review past times around 1 amongst to a greater extent than sense together with thence that I tin capture whatever domain specific scenario which has been missed during mean value through procedure together with around amongst less sense together with thence that he tin improve his code readability, receive got a 4 middle cheque together with most importantly I flora that when i explicate my code to around 1 as component of code review I myself discovery many things which tin hold upwards improved or left out.Overall it ever add together something together with improve code character together with trim down bug.

I also review around 1 else code together with voluntarily receive got component to improve my code agreement powerfulness together with offering assist to others, In this article I volition listing things which I await spell doing code review. These are the things which I receive got been accumulated over the years but I also await forwards to yous guys to contribute your experience, best practices for code review together with advise how yous 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 come across the functional requirement: starting fourth dimension together with firstly does code meets all requirements which it should meet, indicate out if anything has been left out.

2) Is at that topographic point whatever Side number of this change: Sometimes 1 alter inwards your organisation may crusade a põrnikas inwards other upstream together with downstream organisation together with it’s quite possible that novel developer or anyone who is writing code mightiness non hold upwards available of that dependency. This frequently direct related to sense inwards projection together with I flora that the to a greater extent than yous know almost the organisation together with its surround improve yous able to figure this out.

3) Concurrency: does code is thread-safe? Does it receive got properly synchronized if using shared resource? Does it gratuitous of whatever form of deadlock or live-lock? Concurrency bugs are difficult to discovery together with frequently surfaces inwards production. Code review is 1 house where yous tin discovery this past times carefully empathize pattern together with its implementation.

4) Readability together with maintenance:  do code is readable? Or is it as good complicate for some-one consummate new? Always give value to readability as code is non only for this fourth dimension it volition rest at that topographic point for long fourth dimension together with yous take away to read it many times. Another of import appear is maintenance as most of software spends 90% fourth dimension on maintenance together with entirely 10% fourth dimension on evolution it should hold upwards maintainable together with flexible inwards starting fourth dimension place. You tin verify that whether code is configurable or not, await for whatever difficult coding, discovery out what is going to hold upwards changed inwards close futurity etc.

5) Consistency: This is component of indicate 4 but I receive got made it around other split upwards indicate because of its importance. This is the best matter yous tin receive got inwards your code which automatically achieves readability. Since many developer together with programmer receive got component inwards projection together with they receive got at that topographic point ain manner of coding, it’s inwards best involvement of everybody to shape a coding criterion together with follow it inwards missive of the alphabet together with spirit. For illustration it’s non proficient soul using business office initialize() together with other is using init() for same form of operation, snuff it along yous code consistent together with it volition await better, read better.

6) Performance: Another of import appear most of import if yous 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 hold upwards 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 as good amongst predefined together with criterion agency which must hold upwards available together with documented for back upwards purpose. I set this indicate good inwards a higher house on my nautical chart spell doing a review because failing on this indicate tin Pb your application crash together with non able to recover from fault on other organisation or around other component of the same application.

8) Simplicity: Always consider if at that topographic point is whatever unproblematic together with elegant choice available at-least give a thought together with try. Many times starting fourth dimension solution comes inwards hear is non best solution together with thence giving around other thought is only worth it.

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

10) Unit test: Check whether plenty JUnit attempt cases receive got been written together with embrace sufficient per centum of novel code. never allow yous top the code without Junit attempt because developer frequently makes excuse of fourth dimension but believe me its worth to write it.

Not concluding but to the lowest degree that set 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 hold upwards applied during code review. Its also proficient to hold your ain code review checklist or a projection wise code review checklist together with utilization it every fourth dimension spell doing review. There are together with thence many best practices but I receive got entirely included those which I follow together with flora interesting but as I had said before this is the surface area 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
