Coding Standards and Best Practices To Follow

One member of the team submits a pull request to the development branch. When a team member completes a feature, he or she submits a pull request to GitHub. This section describes the request’s content and specifics. Long strings can be wrapped in parentheses as well and will automatically be concatenated. Even if a line of code isn’t 80 characters long, it’s often better to break it into several lines for clarity. A “magic number”is a number in code that is directly used, usually with no information about what the number represents or why that specific number is used.

Also, they are great for illustrating how important it is to write code the correct way. One great use for comments, which has nothing to do with descriptive variable names, is to explain why code changes over time. For example, if the algorithm for choosing the best node changes, the comments should describe that. You can also set predefined groups and reviewers to pull request source and branches, so newer pull requests include them by default. This way, organizations can implement their SCM process in a simple and user-friendly way. The majority of databases allow unencrypted connections by default.

It is usually considered good practice to use descriptive names. Any non-functional system requirements (response time, reliability, maintainability, etc.) need to be considered at this stage. Meek and Heath emphasise that a clear, complete, precise, and unambiguous written specification is the target to aim for. Note that it may not be possible to achieve this target, and the target is likely to change anyway . Before coding starts, it is important to ensure that all necessary prerequisites have been completed .

When PHP was first released many years ago, it was primarily seen as a template engine. It was common to have big HTML files with a few lines of PHP code in between. However, things have changed over the years, and websites have become more and more dynamic and functional. The code is now a huge part of web applications, and it is no longer a good practice to combine it with the HTML. Having different options creates a situation similar to the indent styles, as I mentioned earlier.

There are many linters available on market for different programming languages and IDEs. Some linters even check the code as soon as it is typed and give suggestions immediately. Getting those five benefits should be enough reason to convince any developer or development team to adopt good or best coding practices. That maximizes the efficiency of everything developers code, which ultimately translates into a boost in productivity.

4   Scripts should only contain functions, constants, and an “if-main” block

These harm code quality and velocity, particularly when it happens routinely. Any seasoned developer might point out that only six practices don’t even begin to cover the spectrum of good practices you should be following. That might be true, but for this article’s purposes, those six practices are enough to lay down a solid foundation through which you can achieve higher code quality.

When you run from cleandata import computation_that_takes_forever, the entire script gets run, including the data loading and processing on lines 9 and 10!! We don’t want to run this whole data cleaning process every time we import the function. Article Tools to Track and Manage Technical Debt If you are looking for a tool to start managing technical debt this article will help you make the right decision. We will look at the tools to track small, medium, and large pieces of debt and the process to reduce technical debt.

Add Input Validation to Your Code

Anything before the question mark is the condition, the value immediately after it is the true case and the one after the colon the false case. Ternary notation can be nested, but I’d avoid that to keep things readable. Whilst it is possible to create everything you need in a document using JavaScript and the DOM it is not necessarily the most effective way of doing so.

Improving code readability, maintainability, structure or functionality. Every time you commit a change, a continuous integration/continuous development (CI/CD) pipeline produces a build. Artifact repositories like Cloudrepo, npm, JFrog, enable you to store, organize, and share all builds, making them available for the whole team. They’re essential for rapid releases, easy version tracking, consistency, and enhanced collaboration. Insecure coding often results in vulnerable applications.

The following code puts a red border around every input field when its class is “mandatory” and there’s nothing in it. JSLint can be a bit touchy about the results it returns and — as its developer Douglas Crockford says — it can hurt your feelings. I found myself write much better code however, since I installed the TextMate JS bundle and started subjecting my code to JSLint scrutiny.

best practices for software development and testing

But they can be a great help, especially when you don’t have a lot of time to dedicate to refactoring. Coding standards vary from industry to industry, and they’re very specific. If you’re writing software for a smartphone app, you’ll follow a different standard than if you were writing software for a Tesla car. Consider an example, where you have two variables$is_vaccine_availableand$iva. In a large program, it won’t be easy to guess what purpose$ivaserves without looking through some relevant lines of code. On the other hand, you can guess that the variable$is_vaccine_availableis almost certainly being used to store the status of vaccine availability.

E.g. I think there are better ways to avoid deletion of code than writing a comment that the code is needed… Write a test instead that shows why the code is needed. It’s a so much better way to deal with that issue. I found it useful to write the comments before the code. Describing the flow in plain English often sorted out my thinking about the coding. “// ignore error ” is a bad comment, since it’s easy to see you’ve ignored the error.

While I would say that commenting every statement or even every block is overkill and ill advised, I think that commentary at the function/procedure level should be mandatory. The name of a variable or constant can say a lot about its purpose but the name of a function often pursuing better code practices cannot without making it unwieldy. I make it a rule to include at least one comment at the top of every function. This comment not only summarizes the function’s purpose but also describes its context. I also make it a rule to have some commentary at the module level.

#5 Meaningful Naming Conventions

This limitation affected industry practices after Cisco identified it in a comprehensive study on code review. You can’t correct someone’s code quality without measuring it. Objective metrics help determine the efficiency of your reviews, analyze the impact of change on the process, and predict the number of hours required to complete a project. A code review is a process where one or two developers analyze a teammate’s code, identifying bugs, logic errors, and overlooked edge cases.

  • If the code and comments don’t match, then you can’t trust either.
  • There are many different indentation styles, such as K&R, OTBS, and Stroustrup.
  • Relying on unsafe applications puts your customers as well as your organization’s brand and reputation at risk.
  • Another very insecure practice is to read information from the DOM and use it without comparison.
  • Of course, you should never paste in code that you don’t understand.
  • Good code comments are very helpful when looking at code through a microscope.

This article will detail the 18 most important best practices when writing readable code. Re-use is a very important design goal in software development. Re-use cuts development costs and also reduces the time for development if the components or modules which are reused are already tested.

Ensure Your Code Is Easy to Maintain

In most languages, the “return” statements could also be appended to the prior lines, bringing the “vertical” size to only one more line than the 4th form. Use of proper naming conventions is considered good practice. Sometimes programmers tend to use X1, Y1, etc. as variables and forget to replace them with meaningful ones, causing confusion.

Simple Steps To Solve Any Code Algorithm

Try Invicti scan, Acutenix scanner, or the open-source Zed Attack Proxy . Automated tools to find out the reaction of your application to certain behaviors . BeSTORM, Code Intelligence, or Mayhem for Code are just a few examples of the numerous fuzz testing tools available on the market.

And this just made things worse for us because we were left scrambling to figure everything out when his application broke. Developers come and go, and if they didn’t write clear code, it results in a wave of confusion when they leave. The last time it happened in my team, we learned the hard way how important it is to write code that’s clear and readable for everyone — not only computers.

Voodoo sleeps are hard to understand and slow down your test suite. Logic is easy to unit test if it is stateless and side-effect free. Break out logic into separate functions, rather than mixing logic into stateful and side-effect-filled code. Separating stateful code and code with side-effects into smaller functions makes them easier to mock out and unit test without side-effects.

However, some others (e.g., Microsoft SLQ server) encrypt only the initial authentication process. Don’t let the hackers celebrate — ensure your database traffic is always encrypted. As we said at the beginning, everybody makes mistakes.

However, we also strive to keep our code concise and readable. If the most intuitive name is too long to keep code concise, you’re welcome to use its shorthand. Just be mindful that the shorthand should remain intuitive as well.

1   Example Bad Script

It is very informative for some, but seems like extra overhead to others — it is really up to you whether you use it or not. Exceptions should be exceptional.Don’t indoctrinate exceptions or errors as standard control flow. Not only does this make your code potentially surprising, but it also introduces complexity. Our standard control flow can handle those cases too. This increases testability and re-usability and deters unexpected or unplanned behavior.
