Top Ten Excuses Programmers Gives To Avoid Unit Of Measurement Testing
Though everyone loves unit of measurement tests together with everyone concord alongside benefits they pick out in, when the fourth dimension comes to write them, y'all volition meet a lot of excuses, fifty-fifty from or hence of the to a greater extent than experienced together with senior developers. At the pump of the job of non writing unit of measurement tests or plenty unit of measurement tests they are ii things, kickoff is fourth dimension pressure level i.e. y'all don't receive got plenty fourth dimension to consummate coding forget nearly writing unit of measurement tests. This job comes due to erroneous estimation i.e. alone estimating fourth dimension for coding together with non including unit of measurement testing every bit component of development. This is also our kickoff excuse, hence we'll meet it inwards a brusk while. The 2nd argue is laziness together with ignorance i.e. y'all don't know to write unit of measurement tests but don't set plenty endeavour to larn the tips together with tricks. In this article, I receive got shared or hence of the most mutual excuses given yesteryear programmers for non writing unit of measurement tests.
1) I don’t receive got fourth dimension to unit of measurement test.
Really? But y'all receive got to fourth dimension to ready your mistakes later? The unproblematic fact is that nobody, non fifty-fifty you, tin write bug-free code. Unit tests greatly speed upwardly the fourth dimension it takes to position a põrnikas because they narrow the suspect code downward to a really specific unit. Other types of testing, such every bit Quality Assurance or User Acceptance Testing, position problems at a much higher level, forcing the developer to pass extra fourth dimension plodding through the diverse units looking for the root cause.
Unit tests tin also serve every bit verification that the põrnikas is corrected without having to choke through the hassle of creating a novel application construct together with deploying it for farther testing. Simply put, unit of measurement tests speed upwardly overall development. It mightiness pick out slightly longer to practise each novel feature, but the evolution fourth dimension for the entire application, from inception to delivery, is considerable shorter.
2) Programmers are paid to prepare code, non to write a unit of measurement essay out or comments.
You must empathize that unit of measurement tests are code. They are every bit integral to the application every bit whatsoever other slice of code y'all are writing together with should move included inwards the master copy gauge together with declaration of work. It mightiness also aid to cite to the customer that unit of measurement tests lower both evolution toll (see the previous excuse) every bit good every bit maintenance cost. If y'all are non writing unit tests, together with hence y'all are doing your customer an injustice yesteryear forcing them to incur extra expense.
3) I am supporting a legacy application without unit of measurement tests.
That even hence doesn’t preclude y'all from writing your own. Granted, y'all are non going to move able to choke inwards together with write tests to pick out the entire code base of operations upwardly to an acceptable degree of coverage. You most probable don’t receive got the fourth dimension or resources to practise that. But every bit back upwardly issues are raised, write the unit of measurement tests for whatsoever code that y'all modify.
When I am working on a back upwardly task, 1 of the really kickoff things I practise is write a unit of measurement essay out to recreate the bug. When the unit of measurement essay out starts passing, I know that I receive got fixed the problem. Now, non alone receive got I resolved a bug, but I receive got added or hence unit of measurement essay out coverage to the code base. Over time, this coverage volition acquire to a greater extent than together with to a greater extent than robust, together with actually, trim back futurity maintenance costs yesteryear preventing the introduction of regression bugs. suck upwardly together with ready it
4) QA together with User Acceptance Testing is far to a greater extent than effective inwards finding bugs.
No arguments there. But Unit Testing is far to a greater extent than effective at preventing bugs. Just because my smoke alert is ameliorate at detecting potential fires doesn’t hateful that it is rubber to acquire out the stove on all the time.
Both QA together with UAT are smoke alarms - they alert y'all to potential existing trouble. Unit testing is turning off the stove when y'all are done - it helps y'all forestall trouble. Unit testing, QA, together with UAT are all of import parts of the testing process, together with they each play really dissimilar roles. Trying to supervene upon 1 alongside or hence other doesn’t work. I wouldn’t release a projection that was skillful unit of measurement tested without QA, together with I wouldn’t release a projection that was thoroughly QA’ed without unit of measurement testing.
5) I don’t know how to unit of measurement test, or I don’t know how to write skillful unit of measurement tests.
Well, this is in all probability the most valid excuse that is out there. The distressing truth is that a groovy many numbers of developers together with engineers practise non know how to unit of measurement test. I didn’t when I started. And zilch discourages a developer to a greater extent than than struggling to write bad unit of measurement tests. Luckily in that place are resources out there.
There are hence many books, webinars, conference presentations, blogs, etc on writing skillful unit of measurement tests that the inability to write them exactly isn’t going to cutting it every bit an excuse anymore. When person offers me this excuse, I don’t expect at it every bit a roadblock, but rather every bit a teachable moment.
It ordinarily alone takes a fourth dimension or ii of seeing how good written unit of measurement tests tin aid 1 prepare code to plow them from the nighttime side. If y'all are serious nearly learning tips together with tricks of writing skillful unit of measurement tests together with hence read Test Driven. It volition learn y'all how to unit of measurement tests together with how to improve them slowly.
6) QA volition practise testing
It’s non my task to essay out code – I don’t know at what phase a software developer decides that he tin exactly throw code over the wall. If your task championship was unproblematic Coder than peradventure there’s an excuse. But every bit your task is to prepare working software, y'all demand to move able to say that your code is functional.
7) I write GUI code
Some programmers give excuses that they write GUI code which is hard to essay out together with automate testing is fifty-fifty to a greater extent than difficult. Well, that's non truthful in that place are e'er or hence tools to essay out GUI e.g. if y'all are writing JSP or HTML using JavaScript, y'all tin e'er essay out using Selenium together with other similar tools. It exactly a affair of finding right tools.
8) Unit testing is slower together with painful
It's truthful that if y'all receive got tons of unit of measurement tests inwards your projection together with if they execute every bit component of construct together with hence it volition pick out or hence fourth dimension but alongside the advent of Jenkins together with similar continuous integration tools, y'all don't nee to worry nearly that. Once y'all brand a checking, Jenkins tin start edifice automatically together with alert y'all if whatsoever of your existing unit of measurement essay out failed without y'all doing anything. I advise y'all reading the Continuous Delivery yesteryear Martin Fowler to larn to a greater extent than nearly Jenkins together with other tools.
9) Unit essay out are hard to maintain
This 1 is for sure a genuine indicate but that non skillful plenty to deter y'all from non writing unit of measurement test. Many developers who fifty-fifty write unit of measurement tests neglect to hold them together with alongside to a greater extent than alteration inwards code either those tests are non relevant or fail, but 1 time to a greater extent than alongside the automatic construct together with essay out tools similar Jenkins, y'all volition directly know which tests demand alter every bit component of the recent alter inwards code.
10) Unit testing is boring
It is slow alone if y'all don't know how to write a unit of measurement essay out together with how to essay out your code, but 1 time y'all know that it is the most exciting thing for a programmer. You would dear to write automated tests to essay out your code, y'all volition loathe the traditional main() method agency of testing Java code because of the flexibility together with powerfulness provided yesteryear unit of measurement tests. You tin job fifty-fifty stubs together with mocks to essay out something which is non yet available.
These are or hence of the most pop excuses for non doing unit of measurement tests, I am sure y'all receive got also used 1 of these excuses inwards the past. If not, together with hence either y'all are a professional, disciplined developer or exactly lying. Btw, unit of measurement testing is also 1 of the things which split upwardly an average developer alongside the superstar developer. The later on 1 e'er finds innovative ways to essay out their code automatically together with to a greater extent than consistently.
