When searching for bugs in software products, testing experts, like investigators conduct an investigation. Each bug has its own set of characteristics. To detect the issues a software tester must be familiar with all of them. Let’s look at some of the various types of bugs that can be difficult to identify. 

1. Functional Bug

We can identify this bug by looking over all of the system’s functions and ensuring that they perform as expected. It’s a bug if the feature does anything strange that isn’t specified in the requirements. Let’s take an example: there’s a button in the app that should open window A, but it either opens window B or doesn’t open anything at all. It’s a bug that works. When there are no functional requirements, this sort of bug is more difficult to detect. Previous experience with similar applications comes in handy in this situation. You may also do exploratory testing on your own.

2. Localization Bug

Only if the app supports several languages or is optimized for use in various time zones should you look for localization bugs. The first step is to see if various languages function equally well. The text must be translated throughout the entire system. While detailed documentation is beneficial, you can spot bugs even if you don’t have it. After you’ve modified the default language, go through all of the elements to see whether some of them haven’t been translated. If they haven’t, it’s a bug. Since words and phrases in different languages are of different lengths, you can find UI bugs at this point. As a result, the text can stick out of the block or fully destroy it. Depending on the program, it might be necessary to double-check that the time is shown correctly. Give heed to the date and time format, as it can vary depending on the country. Make a note of the time indicator; it must match the standard time of the nation. If there is a currency change option, make sure it works properly as well.

3. Usability Bug

Usability bugs need special attention because if the software is difficult to use, no one will like it and it will never become famous. When a user can’t identify a function for an extended period of time, such as the registration button, it’s most likely a usability issue. Colors that aren’t well-chosen are often considered a flaw. For example, if the background light makes it difficult to read the text and your eyes become tired after using this application repeatedly. Another common problem is buttons with ambiguous functions: no pop-up hints, no obvious icon or button name. Although the following bugs are not well explained on the Internet or in books, this does not rule out the possibility that they exist.

4. Integration Bug

Integration of software components is possible not only in complex systems but also in well-designed websites. It’s a bug if the information isn’t properly migrated from one variable to the next. There are numerous examples of such a problem. Let’s start with a website that has page A with information B that needs to be transferred to page C. It’s a bug if the details on page B vary from the one on page C. Secondly, consider a large ERP system with numerous component integrations. Assume we create an agreement and choose a profile that matches the data in the clause. 

5. Audio Bug

Not all applications have sounds, but those that do submit alerts or have sound like one of their primary functions should be properly evaluated. The first step is to determine whether or not there is any sound. If this is the case, you must ensure that the sound quality is fine, with no interruptions or distortion. Remember to check the volume to see if it matches the desired level when set to normal, turned high, or low.

6. Device Update Bug

Modern software includes systems or device upgrades as a standard feature. They typically include new features and critical bug fixes, but the update process itself can contain bugs. They’re difficult to come by, but the most popular ones cause the user to lose all of their settings or be logged out of their account. 

7. Content Bug

Editing or copywriting teams are normally in charge of monitoring the website’s content so they understand exactly what needs to be written there. Some content flaws, on the other hand, are far too plain to be overlooked. It may be a typo in the title or a misspelling of the business name. Content bugs include things like missing images and broken links. Finally, we’ll look at a handful of less-obvious tech flaws.

8. User Interface Bug

When you have all of the prototypes of the app displays, it’s far easier to find UI bugs. Simply compare the position, form, color, and other visual elements to the mockup. Design guidelines can be provided in addition to or instead of mockups. The styles and extra information are typically defined in various states in the guidelines. Consider how the color of a connection varies when it’s in its origin point, when it’s floating, and after it’s been clicked. If there is no documentation, don’t worry; you will find the majority of UI bugs by simply looking at the app. Pay close attention to the broken layout, overlapping blocks or components, text that appears to be coming out of the block, and all the components that are out of place or lacking.

There are several other types of bugs that can be discovered during the testing phase, but only a true QA testing expert can find them all. Our 70+ talented QA engineers are on a regular quest to uncover even the most complex software flaws. We are able to polish the apps to perfection, with 300+ physical devices for testing and the latest bug-finding approaches and technologies.
