When it comes to testing software and applications, one of the most critical aspects is identifying and fixing any bugs that may be present and then how to choose the best bug reporting tool.
While many different types of bugs can cause issues in your program, there are some primary types that you should be aware of and keep an eye out for during the testing process as it helps you to implement mobile app testing strategies in a perfect way.
In this blog post, we’ll explore some of these bugs.
Incorrect or incomplete functionality
Functionality bugs are a common type of bug and can occur when the software or system does not behave as intended. This could include buttons that don’t work, an action that results in an unexpected outcome, or an application that does not complete the desired tasks.
These bugs can be challenging to identify as they may only appear when certain combinations of inputs are used. To identify these issues, testers should thoroughly analyse the application or system and ensure it functions correctly and as intended.
Functional bugs are a type of bug that affect the functionality of a program. These bugs occur when the program is not doing what it is intended to do, such as failing to respond to user input, crashing or displaying incorrect information. It’s important to keep functional bugs in mind while testing because they can be extremely difficult to identify and fix.
To find and fix these types of bugs, testers need to thoroughly explore all aspects of the application, including any special functions and scenarios that may cause errors. Additionally, testers should carefully review the source code for any signs of bugs that might have been overlooked. Functional bugs can be some of the most difficult types of bugs to fix, so identifying them early on can save a lot of time and frustration.
UI / Navigation Bugs
UI (user interface) and navigation bugs refer to any errors or issues related to the look, feel and functionality of a website, application or other digital product. These kinds of bugs can be caused by several factors, including incorrect coding, incorrect design or incorrect user experience.
UI and navigation bugs may cause users to become confused and frustrated, leading to a poor user experience. Common UI and navigation bugs include broken links, missing buttons or images, page layout issues, incorrect text or labels, incorrect forms, etc. Testers need to pay special attention to these types of bugs when testing a website or app, as they can have a big impact on usability and user experience.
Input bugs are errors related to how data is inputted into an application or system. These types of bugs can occur when an incorrect data type is entered, the wrong formatting or length of the input is provided, or a user incorrectly interacts with an input field.
Input bugs can be tricky to identify because they can often appear as different types of errors depending on how the data was entered. The best way to detect input bugs is to thoroughly test all possible input scenarios.
This includes verifying that valid inputs are accepted and that invalid inputs are rejected. It is also important to check if the application or system can handle unexpected inputs such as special characters.
System bugs can be some of the most difficult to identify and solve. They arise when there are errors in the software system itself, such as incorrect logic or incorrect coding. This can lead to unexpected results or the application not working at all.
System bugs should always be tested for, as they can have serious consequences for the user. To identify these types of bugs, careful and thorough testing is key.
It is important to test for both expected and unexpected results and to make sure that the system is functioning as expected. By paying attention to details and running rigorous tests, these types of bugs can be identified quickly and easily.
Visual bugs are issues in the way a program or application looks on the user’s screen. This can include text being displayed incorrectly, elements being misplaced, and colours appearing different from what was designed.
These types of errors can easily be missed if not thoroughly tested and can have a major impact on user experience. To ensure accurate identification and reporting of visual bugs, testers can use a screen recording user guide.
By capturing their actions and observations on video, testers can provide a clear and detailed record of any issues they encounter. This makes it easier for developers to understand and address the problem, improving the overall efficiency of the effective bug reporting process. Additionally, screen recording can help testers to replicate and investigate bugs further, ensuring that all visual issues are resolved before release.
Unit-level bugs are typically the most common type of bug you will find while testing. They occur when the code doesn’t match what was expected, such as incorrect calculations, logic errors, and syntax errors.
They can be found at any level of the codebase, ranging from basic data types to complex operations.
These issues are usually caused by developers and can lead to serious security vulnerabilities if not identified and fixed quickly. Unit tests are a great way to detect and prevent these types of bugs from occurring.
By running the unit tests regularly, you can ensure that the code is functioning correctly and that any newly introduced bugs are caught before they cause any real damage.
Syntax errors occur when a program does not adhere to the correct syntax or structure of the language. This could be because of incorrect use of punctuation, incorrect variable naming conventions, or any other deviation from the expected language structure.
It is important to thoroughly test your code for syntax errors, as they can be difficult to spot and often lead to more serious issues in the code.
Additionally, they can be extremely difficult to debug. Syntax errors can be avoided by paying close attention to the syntax of the language when writing code and using appropriate tools such as syntax checkers or compilers to ensure that the code adheres to the correct syntax rules.
Overall, testing is a vital part of the software development cycle. It is important to keep in mind all types of bugs that could potentially affect the software’s performance and reliability. From syntax errors to boundary condition failures and environmental failures, these types of bugs can all be identified and prevented when done correctly.

Additionally, human error should also be considered when looking for potential bugs and their effects on software. Testing is a fundamental part of the software or mobile app development process, and by keeping these types of bugs in mind, the best possible product can be achieved.
