Developers are facing a new software bug that seeks to penetrate their app across all five stages of an application’s lifecycle, i.e., writing requirements, outlining general design elements, building/developing the application, testing/stabilizing the app, and deployment.
As the development process advances through each of its five phases, it becomes a real hassle to maintain intact the current functionality of the app while focusing on correcting yet another bug as well as putting into action a new feature.
Projects Too Sophisticated to Manage
The complexity of a software development project increases throughout its lifecycle, and several factors contribute to this ascending trend, including additional lines of code, new/changed requirements, finding and fixing bugs in software, or adding new features or changing existing features based on customer feedback.
Furthermore, the people who participate in the project have a significant influence on the level of complexity of a project as more people join the team with each step taken toward the next stage.
Not only the number of people grows a project’s complexity, but their different professional backgrounds: quality assurance analysts, or product managers. The migration of team members across projects can trigger loss of knowledge and skills, thus changing the project.
A larger code base is more challenging to manage just because some members are not fully aware of every facet of the app. As complexity escalates, the project becomes harder to manage, i.e., stick to the initial design.
Preventing Hard to Manage Projects
To keep things clear and straightforward, you need a flawless communication system that allows for all project-related information to travel across teams and reach every team member, making sure every single one of them knows and understands the product’s key features.
Teams members need updates related to the implementation of a new feature or changes of an existing key feature, which allows consistency across the resulting code.
Practices to Avoid Most Bugs in Software
1. Requirements Management.
Detailed and precise writing of requirements, as well as a thorough tracking of requirements across the five stages of an app’s lifecycle, are simple practices that help to prevent common software bugs.
2. Functionality Management.
Functionality is the sum or any aspect of what a product can do for a user. Agile practices allow vertical development, which permits presenting functional pieces to the customer across different phases of progress. A software bug is easier to identify early in the process.
3. Writing Unit Tests
A straightforward practice to prevent bugs in software is writing unit tests. The practice will not only help to avoid regression bugs occurring in the development phase but also test the code.
Writing unit tests help to validate requirements while running the code piece by piece and checking the Application programming interface by using it first by the developer who is responsible for it.
How to Avoid a Software Bug in Documentation
- Update the project specification across the development process. You need to make sure you reinforce and maintain the technical and functional specification as you implement new features.
- Trust your team with reviewing the project’s documentation at regular intervals during the development process. A team consisting of a QA engineer, developer, and a designer ought to review the project specifications.
- Keep detailed project documentation because it keeps bugs away from your software. The devil is in the detail.
How to Avoid a Software Bug in Design
There are two rules to stick to if you want to achieve a bug-free design:
- Do not reinvent the wheel when it comes to design best practices and UX/UI guidelines of the platform on which your product will operate.
- Review the design with a QA specialist and a developer irrespective of how valuable your designer is. It will ensure a high standard of quality and functionality.
How to Prevent a Software Bug when Using Third-Party Tools
It is a little more challenging to prevent software bugs when you rely on third-party tools because you cannot control their errors, which can potentially lead to a software bug or project failure both of which can ruin your project inevitably.
How to Create a Bug-Free Application
Developing a bug-free app is not an easy task, and several procedures could help prevent bugs in an app. For a bug-free application, you need to perform the following processes:
- Unit Testing. Unit testing refers to the testing of single functions and modules. It is a time-saving solution that keeps bugs away and the code all good and clear.
- Integration Testing. In this phase of testing, functions and modules are tested in blocks rather than individually. Integration testing is key to confirm how modules interact with each other by following the dependencies between them.
- System Testing. In this phase, the entire system is tested to identify requirements’ compliance and how individual modules perform as a system.
- Acceptance Testing. The acceptance testing process verifies if the system works according to original requirements. Either the product owner or the QA engineer will check the incorporation of all fundamental features.
Implementation Bugs: Definition and Prevention
To understand different types of bugs, you need to have a precise software bugs definition.
Software bugs are errors, flaws, failures or faults in a product that causes it to generate an erroneous or unanticipated result, or to behave in non-desirable ways.
Now, implementation bugs are bugs that come about when the implementation of the code is faulty despite a complete and accurate functional requirements specification. Why do implementation bugs turn up? Possible culprits: messy code, regression, inadequate testing.
- Preventing Implementation Bugs
TDD or test-driven development is a proven method that could prevent the occurrence of implementation bugs. TDD is the backward version of the traditional code-test-debug process. TDD primarily generates failing tests, which outline as well as test the product’s functionality.
Subsequently, code writing is a process that occurs after the tests are working, which allows developers to write a code that can now pass the previously-failing tests. The process is repeated until the code passes all tests, which is proof that it performs as intended.
Messy Code: Definition and Prevention
Messy code is a generic term that refers to apparently minor problems that represent red flags of underlying issues inside the code. Messy code is frequently and informally referred to as code smell or a smelly code.
Experience allows developers as well as other seasoned team members to point out a smelly code, avoiding potentially more significant issues. When projects are rushed to meet deadlines, a messy code tends to become messier, which permits the introduction of one type of software bug or another and will affect the product’s fundamental issues.
Preventing Messy Codes
TDD comes to the rescue once again as it is the most efficient tool that can work against code smell-related bugs. Test-driven development encourages the fracture of the code base into individual concerns and supports recurrent code review and refactoring.
Inadequate Testing: Definition and Prevention
Inadequate testing is also one of the causes of a software bug cropping up and ruining your product. It is therefore important to implement correct testing procedures among your best practices to avoid a potentially fatal bug offensive.
Some developers may see adequate testing as a time-consuming activity while executives and managers might see it as a money-wasting procedure. However, fixing a software bug may entail a lot more time and a lot more money than adequate testing.
Preventing Inadequate Testing Bugs
The key to preventing inadequate testing is continuous integration, a practice that allows creating and testing code following every code review across the development team.
The advantages of continuous integration are many, including the ability to tell almost immediately if a change is compatible with the current code base or if any issues pop up.
The implementation of continuous integration helps prevent inadequate testing bugs as well as cut down on completion time between builds, improve general development speed as well as implementation speed, and allow more time for QA processes and testing.
Regrettably, there are no such things as bug-free apps. It doesn’t mean that you should not focus your efforts on curtailing the number of mobile application bugs. Anyone who promises a 100% bug-free up is a fraud.
There are so many Android and iOS devices in so many different versions. There are a ton of issues resulting from the internet connection’s various speeds and qualities. Plus, there are the problems related to each specific hardware device.
Within this context, foreseeing every single situation that may lead to a problem is impossible. Preventing something that is nearly impossible to predict is just as impossible.
