Test Driven Development Training
Introduction of Test Driven Development Training :
The Test Driven Development Training is a software development process that involves writing test before the actual implementation for Foundation of programming and let me be very specific doing unit testing is not the same thing as doing Test Driven Development Training and the automated unit test its very Amazingly helpful and very worthwhile we’re going to do those unit tests but to do TDD (Test Driven Development Training) we take that idea one step further let’s see the difference most of the developers first encounter this idea of automated unit tests of writing code the tests our code they understandably make the assumption.
this is how the process goes first we would write a bunch of our normal application logic and then we would write our automated unit test to check and verify the logic.

Learn About basic of T.D.D or Test Driven Development Training
- That Test Driven Development Training might sound counter-intuitive if not indeed impossible but I can’t exactly test a method I have not written yet.
- Actually, you can intestine development we don’t just once or twice but all the time. We will write that attempt to instantiate an object where we have not written the class for that object yet we will write tests that call a method that doesn’t exist
- Test Driven Development Training is not a technology it’s an approach and it’s a thought process of thinking testing from a different prospect in normal development scenario first write the code then after writing the test case before writing a single line of code and then you write the code which will run against the test case. This is the fundamental first step of everyday test-driven development the core distinction between doing TDD (Test Driven Development Training)
- we create a new class or a new method and end up staring at a blank screen time to juggle in our heads all the things this might need to pass the test just one tests it keeps us focused this gives us clarity on exactly what we’re doing at any one point don’t do anything more than past this small test.
- Relates to the Extreme programming concept but no on many developers cool of this cycle Red, green, and refractor.
- Test Driven Development Training is not just development uses unit tests Test Driven Development as a process and technique is all about the priority and the position that we give to those unit tests.
- Now if what you’re looking for is to know more about automated unit testing you will find this course very helpful Test Driven Development Training that I will take that is TDD approach to unit testing shifting
- The idea of testing as an afterthought something that we only do later to putting the tests up front it out first let it drive what you write most of the developers this is a very little change in priority but has a dramatic impact on the way that you approach.
- write code so this is focused on automated until testing having a systematic repeatable process that is totally is integrated into our regular project.
People Putting Test Driven Development Training in TDD Context
- People put it in some category and usually they put it in a category of agile development it’s usually connected to a methodology which is called extreme programming which is under that category of agile.
- Under that category of agile and it has a lot of practices a lot of them are technical practices that developers will do one of them is Test Driven Development Training actually tells you to do Test Driven Development Training.
- The good thing in Test Driven Development Training is that you can take this a practice and do it regardless of the methodology to use because it’s something that connects just you in your computer you as a developer can decide to do this just like you as a developer can decide to do debugging no one tells you when to debug your code.
What is Unit test in Test Driven Development Training
- The Unit test is a piece of code an automated piece of code that checks anther automated piece of code it really invokes that other piece of code for example
- We have a function called is login returns a Boolean for those who can’t see now it takes username and password and there is some code in there and probably have a test that what checks calls it with some parameters and checks it returns true calls it with some other parameters checks returns false
Learn about Red, Green and Refactor in Test Driven Development Training
- In Test Driven Development Training Your testing fails and fail are usually involves a red color so that is a read cycle our next you fulfill your expectations you implement some features for which you have written your tests and these are going to be green which means that now on this step hero tests are passing and also note that on this step.
- You write only the minimum code necessary to fulfill your expectations to fulfill on the feature so only very very basic code and then on step three you can refactor your code you can do some changes to it and then proceed may be to the next feature or on your test again to check that after refactor in your code still works or something like this whole concept is mean is called a red green and refactor
- May sound strange and maybe not in under all circumstances it going to feed you especially when you have very little time and you need to very quickly implement some feature and simply don’t have absolutely any on time for testing may be in this case you can skip this but all they know a writing tests is a really good practice
- Later we will see why also note that usually each feature of your program is covered by its own set of test meaning of that you cover all your program by some automated test and usually those tests are independent and they don’t replay to each other they are absolutely independent but later you can write some tests.
- They are term checks aware that the program works properly at the whole because you can write firstly some test that checks individual parts of your program next what next you should check
Learn The Advantages of Test-driven development Training
Unit test makes your developer lives easier
- Easier to find bugs
You have a real application and It has 1200 tests then it is easier to find bugs Why it may not true and those who have really written unit tests will agree what happens when you have bugs in your tests. if you think they maybe they pass but they actually have a bug then it takes a long time to find those bugs so we have fining bugs in the test is a horrible horrible procedure and this may not necessarily be true in fact a lot of the main reasons because people write a lot of logic inside their unit test and the Unit test should be very simple it is something I will also cover in the next talk but this is not necessarily true but there are ways to make it true
- Easier to maintain
It is easier to maintain your application when you have 1200 tests who think this is true? The reasons is necessarily true very simple just imagine that you have a test that creates an instance of some class let’s say its calculator and you have 25 tests for the calculator and now you changed the constructor for the calculator now you have 25 tests that do not compile now you have to go and change each one of them. And the maintaining the application, changing its code may actually break a lot of tests for the wrong reasons they may not compare now and so and so maintenance is actually most of the time for most people is actually harder when you have more tests but there are ways to make this true as well and this is through reusing code refactoring in the tests.
- Easier to understand
It is easier to understand the code when you have 25 tests then, when I say this most of the people don’t understand what I mean understand the code well just imagine that you’re a new developer in the company and you’re tasked with finding and fixing a bug in a specific class now we have never seen this class it’s a huge there is a specific method where you are told the bug is located but you have no idea what it does and how it works the first thing that you do is anyone looking at the test no tests what you do look at the code well what I would usually do is really try to find other references for that method in the code.
how it’s being used what are the use cases for that method and I know in which context it needs to be checked what is supposed to do and so on but when we do automate until testing you can think of each unit test as a small use case an automated use case that tells you what a method or a class a bunch of classes should do in a specific scenario but also this may not be true because most people when they write test write them in an unreadable manner when It renewable I don’t mean that they office gate code but . I mean that they don’t give attention to the
The naming of the test or the naming of the variables in the tests and it’s really important because tests are not just automated tests think of them as API documentation executable documentation. If all these things are true it’s easier to develop.
- Easier to develop
Easier to develop of course making easier to understand is very easy to do you just keep a bunch of naming conventions in check and you can do that now when I talk about test-driven development versus just unit testing there are people who believe that TDD is the answer is the ultimate answer to whatever our problems in our software.
- TDD or Test Driven Development Training doesn’t help with the maintainability of tests.
- They are many people writing test first and write really crappy test.
- They do not help with test readability.
- You can write a test first but it will still not be understandable and these are two very critical facts that we will need to learn regardless of youth doing the test first or after learning good unit testing and learning test first are two different things.
- you can learn how to do proper unit testing and then learn how to do that testing before you write the code. these are two different skills
- when people say Test Driven Development Training and they mean both, but I want to separate them into two that’s exactly why for example the book that I wrote is specifically about unit testing its not about TDD some people say it’s a TDD book. No, it doesn’t even say TDD except just in the first chapter where it says it’s not about Test Driven Development.

Development the core distinction between doing TDD and not Test Driven Development Training doing TDD that before we write any new code. Tests means of describing the code you wish you had firstly once again you describe of what you would like to build and secondly you write this code and I understand that at first this concept may sound strange and maybe not in under all circumstances it well going to feed you especially.
we just wrote for an example we might we write a method called calculated loan we will add some functionality to that compile that and then after we’ve written we think about creating a few test what kind of values might I pass in and verify those results is what we expect and this is unit testing we are testing and individual methods down to the individual methods down to the individual unit in the code but this is not Test-driven development understand that TDD has the same two unit and a test for that logic but it turns the process completely around what test-driven development asks us to developers is to write the test first before we write the application logic
