How to measure the code quality of your mobile app?

code quality of mobile app

Every day, many people adopt smartphones and tablets. And hence applications also come in a package. With every passing year, mobile app is becoming an integral part of the lives of many. This may clarify why, according to the report, by 2022, we can expect more than 258 billion yearly application downloads! There are numerous app available for a single task. 

However, you should take note that it is no longer enough to launch an application. In 2020 and past, to succeed, you should build up a relevant and high-quality application. This is the place where the code quality of your mobile application comes into consideration.

What is Code Quality and Why You Must Care?

Code quality defines code that is good (high quality) — and code that is bad (low quality).

This quality, good, bad- is all subjective. Different teams may use different definitions, based on context. Code that is considered high quality may mean one thing for a web developer. And it may mean another for a web application developer. Regardless of whether the codes of your mobile application are good to rely upon the definitions, you judge them on.

Here, help from resourceful teams of developers is required. You should also remember the context. For example, if you are checking the code quality of a mobile app, the analysis of a developer won’t matter. You may wonder, if code quality is such a subjective index, why does it matter? After all, what difference can it make to your application? Well, if you look for the correct opinion and assessment, code quality describes you a lot about the quality of the software and whether your codebase is safe, reliable, and secure. To recognize a good code from a bad one, here are a few questions you should ask:

  • Is it easy to understand?
  • Does the code do what it was created to do?
  • Is it consistent in its operations?
  • Is the code documented well, for future use?
  • Can the codes be tested?

How to Measure The Code Quality of Mobile App?

There are numerous approaches to measure code quality. Every technique focuses on a basic part of mobile application development. Here are three components and the fastest approaches to measure code quality dependent on the factors in question.

1. Reliability-

Reliability measures the probability that a system will run without going to be failed over a particular time of operation. It relates to the number of defects and the availability of the software. The number of defects can be calculated by running a static analysis tool. Software availability can be measured using the mean time between failures (MTBF). Low defect counts are particularly significant for developing a reliable codebase.

Here are some quick ways to measure the reliability of a code:

  • Keeping tabs on production incidents: The lower high priority errors are recognized during the application development process, the higher is the reliability score.
  • Load testing whereby you check how the code functions when more users use it.
  • Regression testing, where you count the number of new defects that come when you attempt to change the application, keeping the given code consistent.
  • Reliability evaluation where specialists make a market-like environment and see whether the application works seamlessly in the stimulating environment.

2. Security-

While living in an online world implies that our sensitive information is more vulnerable than ever; this doesn’t imply that steps can’t be taken to prevent such problems.

In fact, like never before, users are now cautious about which application they download. Each user wants a secure application, and this security starts at the coding level. This is the reason to check the security of the codebase is an incredible method to measure the code quality of a mobile application. Hackers are probably going to breach software and access to highly sensitive and personal data if poor coding practices are used. Hence it is essential to minimize the number of vulnerabilities an application faces on the coding level. Here are fast and tested ways for evaluating code quality based on security.

  • Scanning the mobile application to recognize the number of vulnerabilities present in the application.
  • Sending a Security update in case the application has been launched. Analyze the number of users who have updated the application and whether its vulnerabilities have decreased since then.
  • Identifying real security occurrences and checking the seriousness and frequency.

Measuring the code quality based on security implies waiting until you launch your application. However, since application development is a continuous process, this factor ensures that your mobile application is flexible enough to handle issues that emerge with time.

3. Maintainability and Testability-

The simplicity with which software and thus a codebase can be maintained governs whether it is of high quality. To measure code quality based on maintainability, it is necessary to assess the structure, consistency, and complexity of the codebase in question.

Here, factors like testability come in. It is difficult to give a single rapid metric to judge the quality of a code dependent on maintainability. Famous ways include estimating the number of stylistic warnings that arise and running the code through a series of Halstead complexity tests. Also, the testability of the code can be estimated through cyclomatic complexity and recognizing the number of tests that come in faulty.

4. Reusability-

Reusability estimates whether existing assets-, for example, code — can be used again. Resources are easily reused if they have characteristics, for example, modularity or loose coupling. Reusability can be measured by the number of interdependencies. Running a static analyzer can help you with identifying these interdependencies.

How to improve code quality?

Measuring quality helps you to know where you’re at. After you’ve measured, you can find a way to improve overall quality. Here are four ways you can improve the quality of your code.

1. Use a Coding Standard-

Using a coding standard is the most ideal approach to ensure high-quality code. A coding standard ensures everyone uses the right style. It improves the consistency and readability of the codebase. This is key for lower complexity and higher quality.

How to Do It?

The best way to use a coding standard is to:

  • Train your developers
  • Help them to comply with it

You can do this by using a static code analyzer.

2. Analyze Code — Before Code Reviews-

Quality should be a priority from the very start of development. There isn’t always the luxury of time as development progresses. That is the reason it’s essential to analyze code before code reviews start. What’s more, it’s ideal to analyze code when it’s written.

In DevOps, code analysis occurs during the creation stage. Static analyzers can be run over code when it’s written. This creates an automated feedback loop, so developers can improve code before it goes to the code review stage. After all, the earlier you discover errors, the faster, simpler, and cheaper they are to resolve.

How to Do It?

The most ideal approach to improve quality is by analyzing code automatically. By running a static analyzer over code early and frequently, you’ll ensure the code that gets the code review phase is the best quality possible. Additionally, you can use static analyzers, (for example, Helix QAC and Klocwork) to monitor key quality metrics.

3. Follow Code Review Best Practices-

Manual code reviews are still significant for verifying the aim of the code. When code reviews are done nicely, they improve overall software quality.

How to do it?

The most ideal approach to do code reviews is to follow best practices and exploit automated tools.

4. Refactor Legacy Code (When Necessary)-

One approach to improve the quality of a current codebase is through refactoring. Refactoring legacy code can help you clean up your codebase and lower its complexity.

Wrap up- 

Here you have seen some effective ways to measure code quality of your mobile app. From these, you can measure the code quality of your mobile apps and take appropriate actions to improve the quality. This can effectively help you to develop a winning mobile app.
