How can you ensure your code is always working as expected? This is a crucial question for any system developer who wants to deliver reliable and high-quality software. In this article, you will learn about some of the best practices and tools that can help you achieve this goal.
One of the most important steps to ensure your code is working as expected is to test it thoroughly. Testing can help you find and fix errors, bugs, and vulnerabilities in your code before they cause problems for your users or clients. There are different types of testing, such as unit testing, integration testing, functional testing, and performance testing, that can cover different aspects of your code's functionality, quality, and efficiency. You can use various testing frameworks and tools, such as JUnit, Selenium, PyTest, and Mocha, to automate and simplify your testing process.

In addition to testing that specific units of code are not generating errors and returning the correct output, it's also important to expand your tests beyond simple unit and integration tests. Using Behavior-Driven Development (BDD) involves writing tests for the requirements of a system in an human-like language, and then running tests to ensure that the application is doing what was originally expected. Writing these tests in a formalized language such as Gherkin provides a way of collaborating on features with non-technical people, and then generating technical tests to achieve the behaviors described in those features.
Another essential practice to ensure your code is working as expected is to use version control. Version control is a system that tracks and manages the changes in your code over time. It allows you to create, update, and delete different versions of your code, as well as to compare, merge, and revert them. Version control can help you avoid losing or overwriting your code, as well as to collaborate with other developers more easily. Some of the most popular version control systems are Git, Subversion, and Mercurial.

A third way to ensure your code is working as expected is to follow coding standards. Coding standards are a set of rules and guidelines that define how you should write, format, and document your code. They can help you improve your code's readability, consistency, and maintainability, as well as to avoid common errors and pitfalls. Coding standards can vary depending on the programming language, the project, and the organization you are working for, but some of the general principles are to use meaningful names, indent your code properly, comment your code clearly, and avoid hard-coding values.

A fourth method to ensure your code is working as expected is to perform code reviews. Code reviews are a process of examining and evaluating your code by yourself or by other developers. They can help you identify and correct mistakes, improve your code's quality and performance, and learn from other's feedback and suggestions. Code reviews can be done in different ways, such as peer reviews, pair programming, or pull requests, and they can use various tools, such as CodeClimate, SonarQube, or Codacy, to automate and facilitate the process.

A fifth technique to ensure your code is working as expected is to implement continuous integration. Continuous integration is a practice of integrating your code with the main branch or repository frequently and automatically. It can help you detect and resolve conflicts, errors, and bugs early and often, as well as to ensure your code is always up-to-date and ready for deployment. Continuous integration can use various tools, such as Jenkins, Travis CI, or CircleCI, to automate and monitor the integration process.
Continuous integration is the most effective when working on a larger code base where collaboration between developers is an important feature. It should not be used in isolation, but instead should be combined with unit tests, integration tests, and BDD tests to ensure that the code passes a minimum threshold of quality before it's integrated. Continuous integration strategies work best when the team has multiple environments to deploy into for more thorough integration testing, and can roll back a change quickly when there are unexpected behaviors introduced in an update.
A sixth and final step to ensure your code is working as expected is to deploy your code. Deployment is the process of transferring your code from your development environment to your production environment, where it can be accessed and used by your users or clients. Deployment can help you verify and validate your code's functionality, usability, and security, as well as to collect feedback and data for further improvement. Deployment can be done manually or automatically, and it can use various tools, such as Heroku, AWS, or Azure, to manage and scale your code.
