Code quality is classified either as a good code (high quality) or a bad code (low quality). Regarding the terms ‘quality, good, and bad’ — all these can be subjective as to whoever defines it.
For various teams, code quality may have different definitions, according to its intended context. Good code quality may mean differently for an automotive developer as compared to an offshore development expert.
Does code quality matters
Code quality is essential for achieving the overall target software product. Quality ensures a reliable, safe, and secure codebase. Currently, maintaining high quality is crucial for many offshore development teams, which is vital for developing safety-critical processes.
Good vs. bad code quality
Good code provides high quality with a clean code. It can withstand the test of time. Meanwhile, bad code is low quality, which does not last long.
In general, good code quality means that the code can do what it is supposed to do, adheres to a consistent approach, can be easily understood, and follows well-documented guidelines. Also, it can be evaluated by testing the created code.
Testing is inadequate
Even programmers are prone to committing mistakes. By simply doing manual code reviews and testing, these are insufficient to detect any code error.
Based on a related study on software defect origins and removal methods, this highlighted that individual programmers are more likely to be inefficient in spotting the bugs in the software that they developed. For most testing activities conducted, they conducted them with less efficiency, causing difficulty in ensuring quality.
Coding errors cause potential risks
Attaining code quality in programming is crucial. For a low-quality code, it could bring safety or security risks. In case the software fails caused by security issues or safety defects, these can lead to damaging results or at times, can be fatal to the software development company.
Quality is everybody’s responsibility
Promoting good code quality should be everyone’s concern. This involves the offshore development team, software testers, and project manager. To achieve high quality is key to the team’s goal in the entire duration of the development process.
Gauging code quality
Measuring code quality varies based on the software app. What you measure may not be the same for the development team doing a similar task.
Key approaches in measuring code quality
Below are key traits when identifying high-quality codes.
Reliability. This ensures that any process will be implemented without any failure over a specific period. This involves several defects are resolved and all necessary software is available. Various defects can be identified by employing a static analysis system. For software availability, this can be measured through the mean time between failures (MTBF). Low-defect counts are vital for creating a reliable codebase.
Maintainability. This refers to how software can be maintained without any hassles. It includes the codebase’s consistency, size, structure, and complexity. Also, this approach ensures a source code is maintained by relying on several factors like testability and understandability.
A sole metric cannot be used to attain maintainability. Other metrics that are needed to enhance maintainabilities are stylistic warnings and Halstead complexity measures. In developing easy-to-maintain codebases, this involves both automation and human reviewers.
Testability. This identifies how much the software supports evaluation efforts. Among other factors, this is dependent on how well the offshore development team can control, isolate, observe, and automate testing. Measuring testability is based on the number of test cases where you can spot potential defects within the system. Both software size and complexity affect testability. When applying the processes at the code level like cyclomatic complexity, this can assist in enhancing testability.
Portability. This pertains to how usable a similar software is when used in different environments. Also, this relates to the required independent platform. In general, there is no specific portability metric. However, there are different ways to ensure a portable code. It’s critical to frequently test the code on various platforms instead of waiting until the final software development. Also, it is highly advised to place your compiler warning at high levels as much as possible while employing two compilers. By implementing a coding mechanism, this can help determine portability.
Reusability. This identifies whether the current codes or assets can be reused. Assets can be easily reused in case they have features such as loose coupling or modularity. This key approach can be measured based on the number of interdependencies. Using a static analyzer, this can help in checking these interdependencies.
Setting the product release on time
Any offshore software development team adheres to the main task of launching its assigned products to the market. However, before releasing an app to the end-users, software firms must ensure that their new product launches have passed through the standard code quality processes.
Code review is a crucial approach in offshore software development. However, oftentimes, to meet a tight deadline, code testing is frequently overlooked by some offshore companies. Also, this task can be time-consuming. There are different ways to ensure code quality. Check which of the available methods will work best for your offshore development team.
Frequent code reviews
Most small firms usually carry out ongoing code reviews as these mandatory schemes are affordable and beneficial for everyone involved in the project. With regular code reviews, these are collaborative efforts conducted during management and peer reviews. Also, enterprises can do code reviews by employing platforms that evaluate codes while seeking flaws in offshore development tasks.
By performing regular code reviews, software firms can have a more comprehensive understanding of the development process. No project manager wants to be at the finish line of the development phase and still find basic coding errors that need immediate attention. In case things will not work well in the right direction, underperforming staff can be taken somewhere else to prevent further issues that can be detrimental to the overall project implementation.
Remote workers are the main candidates for testing activities. For an offshore development team, their work quality can be evaluated at different segments of development through scheduled code reviews. These reviews are usually vital to ensure attaining positive results while providing project managers incentives to outsource software development tasks in the future.
Many clients have high expectations that an app will meet its expected features. The testing is held to check if the expected results are viable. Functional testing is also called the black box method. This is used to verify the coding quality based on how well the different features work within the app.
Functional testing goes beyond the detailed coding features and digs deeper on what may occur when the users take action on the app’s front-end. In this type of testing, you can easily detect among the end-users who are more concerned with code testing or interested in the overall product performance.
Related to the functional testing concept is user acceptance testing. User acceptance testing is a simple process that enables developers to check the software as the customer identifies the satisfaction level of a user while employing the app after its market release.
Generally, unit testing is widely used in large projects based on the available time to properly implement the testing. However, the advantages of unit testing are far better when resolving potential time delays. During unit testing, the offshore developer validates each code line and then examines it for potential mistakes or errors.
This type of testing ensures the software is properly functioning. By evaluating every code line, developers can easily detect the bugs that might corrupt the software. Aside from ensuring code quality, unit testing is employed to train developers to be more analytical when writing codes.
The two most common unit testings include statement and pass coverages. Statement coverage checks each code line while pass coverage is more comprehensive between the two. Pass coverage involves analyzing each code line by undertaking a test case and validating the code line’s capacity.
This method of testing code quality looks into how every new code impacts the software. Changing programs by entering a code is designed to enhance an app but this can also lead to interference. Regression testing is conducted after any coding revision to ensure that no flaws are identified within the system.
Outsourcing software development through offshoring reduced the time to release your product in the market. However, you need to ensure your app does not contain any faulty code, where even the small details should never be overlooked and always tested for potential errors.
Code quality needs a series of testing and review periods during offshore development. Full code evaluation in each development stage is the best way to help your software company and the offshore team to guarantee user satisfaction and secure a reliable app.
