How to make code review helpful

Must read

Introduction

When it comes to code reviews, there are a few things that you can do to make sure that they are helpful. First and foremost, you want to be clear about what you are trying to achieve with the review. Whether you are looking for high-level feedback on the direction of the project or you are looking for specific comments on the code itself, being clear from the outset will help everyone involved in the review process.

Next, it is important to give reviewers enough time to look over the code and provide their feedback. Trying to rushing through a review will only result in sub-par feedback that is not helpful to either party. Similarly, you should avoid scheduling a review too far in advance as things can always change between when the code is written and when the review takes place.

Finally, when it comes time to actually conduct the review, be respectful of everyone’s time and opinions. This means keeping an open mind during the discussion and being willing to compromise if necessary. At the end of the day, remember that the goal is to improve the code, not just point out faults. With these tips in mind, your code reviews should be much more productive and helpful for all involved.

What are code reviews?

Code reviews are a process in which two or more developers review each other’s code. The aim is to improve the quality of the code and to find any potential errors. Code reviews can be done manually, or they can be automated using a tool like Checkstyle.

When done manually, code review usually follows these steps:

1. The developer writes some code and submit it for review.
2. The reviewer looks at the code and makes comments on it.
3. The developer takes the reviewer’s comments into account and makes changes to the code accordingly.
4. Repeat steps 2-3 until the reviewer is satisfied with the code.

Automated code reviews are similar, but instead of a human reviewer, a tool like Checkstyle is used to check the code for errors.

What is the purpose of a code review?

A code review is a process in which a programmer or team of programmers check the code of another programmer to find errors and improve the overall quality of the code. Code reviews can be done on any type of code, but they are most commonly done on software code.

Ensuring quality code

As a code reviewer, it is your responsibility to ensure that the code you are reviewing meets the necessary quality standards. Here are some tips to help you accomplish this:

1. Use a consistent coding style guide. This will help to ensure that the code is easy to read and understand.

2. Pay attention to details. Make sure that all code comments are clear and concise, and that there are no typos or errors.

3. Take your time. Don’t rush through the review process; take the time to carefully examine each line of code.

4. Be open-minded. Remember that not all coding styles are equally valid; be willing to consider different approaches and find the one that works best for the specific situation.

5. Be constructive. If you have suggestions for improvement, make them in a way that is respectful and helpful.

Knowledge sharing and teamwork

In any organization, knowledge sharing and teamwork are essential to success. Code reviews are no different. In order to make code reviews helpful, it is important to keep the following in mind:

1. First and foremost, code reviews should be collaborative. All members of the team should feel like they are able to contribute.

2. Code reviews should be constructive. The goal is to improve the code, not to tear it down.

3. Code review comments should be specific. General comments such as “this doesn’t look right” are not helpful. It is much more helpful to say something like “line 17 is missing a semicolon.”

4. Finally, don’t forget to follow up after a code review. If there are changes that need to be made, make sure they are made in a timely manner.

Security

As a developer, it’s important to reviewer code with security in mind. This includes looking for potential vulnerabilities and exploits that could be used to attack the system. Here are some tips on how to make code reviews more secure:

1. Check for known vulnerabilities. There are many databases of known vulnerabilities, such as the National Vulnerability Database (NVD). These can be searched by keyword or CVE number. Checking for known vulnerabilities is a good first step in securing code review.

2. Look for insecure coding practices. Insecure coding practices can lead to vulnerabilities even if there are no known exploits for the particular code being reviewed. Some examples of insecure coding practices include:

– Use of hard-coded passwords
– SQL injection flaws
– Cross-site scripting (XSS) flaws

3. Use static analysis tools. Static analysis tools can help automate the process of looking for potential security issues in code. Some popular static analysis tools include:

– OWASP Zed Attack Proxy (ZAP)
– HPE Fortify
– IBM AppScan Standard
-Microsoft Security Code Analysis (MSCA)
4. Review access control measures. Access control measures should be reviewed to ensure that they are adequate and properly implemented. This includes reviewing things like:
– Authentication mechanisms
–Authorization controls

5–Access control lists

 6–Role-based access controls

What Is the Difference Between a Code Review and a Code Checker?

When it comes to code reviews, there is a lot of confusion about what exactly they are and what their purpose is. Are they just a chance for the author to show off their work? Or are they a way to catch errors and potential problems?

In reality, code review is a bit of both. A code review is an opportunity for the author to present their work to others for feedback and corrections. A code checker, on the other hand, is a tool that can be used to automatically check for errors in code.

There are benefits and drawbacks to both approaches. Code reviews can be very time consuming, especially if there are many people involved. And because they rely on human beings to spot potential problems, they can sometimes be ineffective. Code checkers, on the other hand, are much faster and more accurate. But they can also be expensive, and they can’t always catch every error.

So which approach is best? It really depends on the situation. If time is not an issue and you want to be absolutely sure that your code is error-free, then a code checker is probably your best bet. But if you’re working on a tight deadline and need to get your code into production quickly, then a code review may be your only option.

What Should a Good Code Review Look Like?

A good code review should be thorough and cover all aspects of the code being reviewed. It should identify any potential problems with the code, and offer suggestions for improvements. The reviewer should also take into account the objectives of the code review, and tailor their comments accordingly.

Create a Checklist for Code Reviews

When it comes to code reviews, creating a checklist can be helpful in order to make sure that all aspects of the code are being checked. This checklist can vary depending on the programming language(s) being used, but some items that should generally be included are:

-Making sure that there are comments for every block of code
-Checking for consistent indentation throughout the code
-Ensuring that all variables and functions are named appropriately
-Verifying that all input and output values match what is expected
-Confirming that there are no unused or unnecessary lines of code
-Looking for any places where the code could be simplified or written more efficiently

Include Benchmarks and Metrics

As a reviewer, it is helpful to include benchmarks and metrics in your review. This allows the author to see where their code stands in relation to others’, and identify areas for improvement.

When providing feedback, aim to be as specific as possible. For example, instead of simply saying “this code is slow,” provide details on how long the code took to run, or what percentage of the total runtime it accounted for. Include any relevant graphs or screenshots that help illustrate your point.

If you’re not sure what benchmarks and metrics are relevant, ask the author! They likely have a good understanding of what their code needs to achieve, and can provide guidance on what would be most helpful for you to include in your review.

Explain Your Feedback

When you’re giving feedback on code, it’s important to be clear, concise, and specific. Remember that the goal is to help the author improve their code, not to criticise them.

Here are some tips for giving helpful feedback:

– Explain why you think something needs to be changed.
– Provide specific examples of what could be improved.
– Offer alternative solutions where appropriate.
– Be open to discussion – remember that the author may have a different perspective on the problem.

How Can I be a Better Code Reviewer?

As a code reviewer, your job is to help the author improve their code. This can be done by providing constructive feedback on the code itself, as well as on the process and tools used.

To be a better code reviewer, you should:

– Be clear and concise in your feedback.
– Be specific about what you liked and didn’t like.
– Suggest alternatives if you have them.
– Ask questions to clarify your understanding.
– Be open to discussion and debate.

Be Humble

When it comes to code reviews, it’s important to be humble. Remember that you’re not the only one who knows what they’re doing, and that everyone has something to contribute. Be open to suggestions and feedback, and don’t take it personally if someone points out a flaw in your code. It’s all part of the learning process!

Critique the Code

When it comes to code review, there are two main schools of thought: those who believe that critique should be focused on the code itself, and those who believe that critique should be focused on the coder. We believe that the most helpful code reviews are a combination of both.

When critiquing the code, it’s important to keep in mind that everyone has different coding styles and preferences. What may be considered “bad” by one person may be considered “good” by another. The best way to approach critiquing someone’s code is to assume that they are following best practices unless there is evidence to the contrary.

That said, there are still some general guidelines you can follow when critiquing code:

– Look for ways to make the code more readable. This includes making variable and function names more descriptive, breaking up long lines of code, and adding comments where needed.

– Check for any potential bugs or errors. This includes things like off-by-one errors, infinite loops, typos, etc.

– See if there are any unnecessary steps or redundancies in the code. This can make the code more difficult to understand and maintain.

– Make sure that the coding style is consistent throughout the entire project. This includes things like indentation style, spacing, etc.
