TDD methodology for custom web programming

[mostakimvip06]

Custom web programming , as with other types of development, implies that the project will be carried out in a specific way, following the client's requirements. By avoiding standardized solutions, we achieve more optimized results that usually provide superior performance.

On the other hand, since there will be a greater web development load , both on the server and on the front-end, it will be common to require more time to complete the web project.

In addition, as development progresses, the volume of lines of code and programmers involved in it will grow. This will lead to greater difficulty in controlling bugs or errors in programming .

Facing this type of custom programming scenarios without a defined methodology for uk telegram data our team of developers can become a bottomless pit for our time and resources.

To deal with this type of project, there are development techniques such as TDD , which we apply at La Teva Web for custom web programming.
What is TDD methodology?
Test-driven development (TDD) is a programming technique that allows you to tackle large software projects, reducing them to smaller units based on the tests or requirements that the developed project must pass.

A practical example : a client who asks us to develop a custom website that allows booking tourist accommodation.

In a traditional programming model we would approach the project in the following way:
Initial data collection and requirements with the client
Definition of what our application should do
Defining how we will implement our code
Development
Testing the entire system
Delivery to the customer
The problem with this type of approach is that in the final stages , both in testing and in delivery to the client (even after delivery), we can find several errors that prevent the website from working. At this point, we must review all our code and go back to the implementation stages to correct them. In large projects, this cycle can repeat itself ad infinitum .

And how does the TDD methodology solve this problem? Following the example mentioned above, with the test-driven development technique we would carry out the following steps:
Initial data collection and requirements with the client
Definition of what our application should do and fragmentation of the functionalities into testing units, which allow:
Encapsulate the code that corresponds to each individual requirement
Define what this fragment and its corresponding test should do, marking what the conditions will be for it to pass successfully.
Definition of how we will develop each unit of code
Development of the different units individually
Testing of each unit
Refactoring and final review
Delivery to the customer
