What is test driven development? This is a question that one might ask that would like to begin using this method but they’ve never had previous experience with it before. Test driven development is when an evolutionary approach for particular software is being created but before it can fully function the plan for it is written out. Also more like a written plan which shows the details of what can be expected to occur when the development is completely finished. This will help the developer have a visual before they fully execute the plan and then they can make any last minute changes that might be needed.
The main goal of test driven development is to show specification of a development plan in progress. So before writing your functional code this is just the planning and thinking process.
Now that you know what the main goal of test driven development, let’s move on to a more detailed description of how each step works with executing this plan. The first step is to add a small test which will most likely fail since the code will be small. Next, you will need to run your test, a subset; this is to make sure that it fails. Update the functional code after the test fails so that it will pass the next test that you run. After you have finished the update, step four is to run the test again. If for some reason the test fails again then you will need to proceed in updating your functional code again, then retest again. After the test passes it’s time to move along to the next step which would be to start over again.
There is a formula that is used which best describes test driven development below:
Test Driven Development = Refactoring + TFD
Test Driven development has been known to change the process of average development around. When you first begin to execute a feature, then you need to ask if it is a design that already exists is best to start off with or if there should be a new method to add to it. If you decide that you will be going with the existing design, then you will take an approach with TFD. If you will be going with a different design however, then you will need to refractor the current design to a totally new feature. By using the formula mentioned above it will make it possible for you to improve your current design a lot easier when you plan to change it up later on in the future.
The testing code will be written first in this case and then next your functional code. Do this in small steps to ensure that everything works as planned. Do one step with a small amount of corresponding with a functional code each time. The programmer that is using the TDD method will usually not accept a new design until the current one fails. The code will also be refused until there is an existing test that is created for it. When the test succeeds then the work is presented which is required for the suite to pass. Although this might sound like an easy process, for those of you that are beginners it can take a lot of patience to get used too. Take your time and don’t try to finish the job too quickly; you must be precise.
Now, there are two different types of test driven development that can be used depending upon what type of software you are working on. First there is Acceptance TDD (ATDD). This type of development requires that you either perform an acceptance test or a behavioral test. You will need to use a minimal amount of code to proceed in being successful with this test. The second type is called Developer TDD. With this version of TDD you will need to only write one test. Then use enough code to fulfill the needs of the test. The main goal of Developer TDD is to have a detailed test which would be the proper solution for just in time basis. Developer TDD is usually the easier option to choose for most people.
