Software Development Techniques
Software development is a complex process involves the creation of computer programs to meet specific needs. To carry out this process effectively, a variety of techniques are used, ranging from planning and design to implementation and delivery of the final product.
1.Agile Methodologies
Agile methodologies are an approach to software development that focuses on flexibility, collaboration and incremental delivery. Scrum, Kanban and Extreme Programming (XP) are common examples of agile methodologies. These techniques enable teams to adapt quickly to changing project requirements.

2.Test Driven Development
+ Red
Test-driven development is a technique that involves writing automated tests before writing production code. This approach helps ensure that the code meets the specified requirements and facilitates early detection of errors.

3.Continuous Integration (CI) and Continuous Delivery (CD)
Continuous Integration (CI)
Continuous integration is a practice where code changes are automatically integrated into a shared repository several times a day.
Continuous Delivery (CD)
Continuous delivery is actually an extension of Continuous Integration, where changes can be automatically deployed to a production environment once all the necessary tests have been passed.
4.Spiral Development
The spiral development model is an iterative approach that combines elements of waterfall modeling with prototyping techniques. Spiral development is especially useful for large-scale projects or where the requirements are not well defined from the start.

5.Extreme Programming XP
It is an agile methodology that focuses on simplicity, communication and continuous feedback. XP teams work in short development cycles, performing frequent testing, refactoring code and prioritizing the most important features for the customer.

DESIGN
Programming here is done "two-handed", in pairs in front of the same computer. Sometimes the pairs are even exchanged. In this way, we ensure that a more universal code is made, one that any other programmer could work with and understand.
They are prioritized and broken down into mini-versions. The schedule will be reviewed on a rolling basis. Approximately every two weeks.
In this step we will try to work with a simple code, doing the minimum necessary to make it work (prototype).
It means that we have tested all the user stories or mini-versions successfully, adjusting to the customer's requirements. We have useful software and can incorporate it into the product.
Automated testing must be performed continuously. As these are usually short-term projects, this automated and constant testing is key.

GREEN
Do the minimum necessary for the test to pass. Usually, a passing test has a green color on a test runner.
REFACTOR
En este paso se limpia el código productivo y se refina su estructura. Podría decirse que ahora está completado y reestructurado de forma que resulte elegante y comprensible para los desarrolladores.
RED
Start by creating an automated test that fails from the beginning. Usually, a failed test has a red color in the test runners.
