While performing software testing, there are numerous things that you have to take care of, and we always try to focus on them in our articles. Peer review is one of the most important steps that should occur post-creation of tests to ensure that the test suites are fine and the entire quality engineering team can work collaboratively to make decisions.
Now, as you have already seen in our previous articles, modern agile practices like shift-left testing need the software testing phase to be shifted earlier in the development life cycle. That means with earlier testing, the necessary steps like peer review should be performed with more precision to ensure that the overall efficiency of the process remains high.
Peer review is the traditional name of the process of rechecking different parts of the automated tests and working based on collaborative feedback & approval for improving the quality of the tests as well as of the codebase. It is a useful step in ensuring the best quality across all artifacts and deliverables such as the codebase, designs, architecture, business requirements, test cases, user stories, and so on.
To make the best out of such high dependence on low-code automated testing in present times, you surely need to follow the best practices for peer reviews, and the same we are going to see in the further sections.
The whole point of performing the review is to find out as many defects as possible so that the tests can get the maximum accuracy. Now, the human brain can efficiently process a limited set of information at a time, and according to some sincerely conducted research, reviewing a maximum of 400 lines of code (LOC) at a time can let you maintain accuracy in your code review process.
An effective way of maintaining the concept of taking proper time for inspection is setting small achievable goals for the review. Also, it is a wise approach to avoid reviewing more than 60 minutes or more than 500 lines of code (LOC) at a time. Reviewing code in a reasonable quantity can be beneficial for both technical and business aspects.
Now, coming to the metrics, they can really help you get rid of a lot of difficulties in your review process. For example, external metrics can lead you toward reducing support calls or the bugs induced during development. Also, remember to pay attention to the internal metrics such as -
We have jotted down a few questions that you should find answers to while reviewing the test title, description, and metadata.
The developers who have written the code know every minute aspect of it. There are certain parts of the code that should be reviewed first to achieve better efficiency. Hence, consider getting annotations from the authors of the code to prepare effective strategies for the peer review process.
Analyze the test step descriptions to get answers to the following questions.
Checklists are always a great way to ensure that everything is being taken care of. Now, when you work with teams containing multiple members, it is very likely that each one of them will make a few repetitive mistakes that are normally hard to detect in normal working motion. Omission is one such mistake that is difficult to detect because you are trying to find mistakes in something that is not even present there.
Hence, to detect such omission mistakes, you must have a clear idea of everything that should be present in the code, and nothing is better than a checklist to keep track of everything that should be present in the code. A checklist is a widely used method to ensure that every necessary thing is taken care of before proceeding towards the next step in anything. Similarly, use a code review checklist as an important step in your code review process.
Reviewing the test in action is the best way to check if the steps are moving as expected. So, replay the test steps in a non-live environment and analyze how it responds to the following questions.
Consider reviewing how the tests will be run and what the best-suited configuration will be.
Re-reviewing the test steps can significantly help you in taking some great steps. So, find answers to the following questions during the re-review process.
Detecting the bugs is not the end of the story. They need to be properly fixed so that the final product solves the users’ requirements. So, you must have a systematic process to fix the detected bugs.
Now, one of the most effective ways of fixing bugs is using an efficient automated testing tool like Preflight that allows your entire team to work collaboratively for finding and fixing bugs. This tool can provide you with significant benefits that can truly improve your QA experience.
Any process can only be successful when everyone willingly gives their best effort to walk toward collaborative growth.
Now, in terms of code review, it is a possible scenario where senior developers may get offended by the fact that someone will review their work for correctness. In such a case, it is the role of the managers to maintain a healthy, collaborative work culture where everyone embraces others’ feedback & suggestions, and works for holistic growth. That way the work will get the best results and everyone will get amazing opportunities to learn new things.
Peer review is a great way to ensure that the codebase of your products does not have bugs and that you can launch a perfectly working product. In this article, we jotted down some of the best practices followed by the most successful tech businesses around the world for performing low-code automated tests with the objective of achieving maximum efficiency.
One of the most important aspects besides following these guidelines is using an efficient low-code test automation tool like Preflight to fulfill all your testing needs. And, it is by far the most effective step too. This simple browser extension can easily enable anyone to create, run, and manage complex test cases irrespective of their coding knowledge. You can get to know about all the amazing features of this tool from the article “10 Amazing Software Testing Benefits From Preflight In 2022”.
