Phone Bugs: How to Find Issues in Mobile Applications

How to Find Phone Bugs?

While a tester might catch a few issues using various tools, skipping proper bug management can leave major bugs unnoticed, posing risks to the business and increasing costs.

To avoid this, it’s crucial to follow a structured and organized testing process for the best results.

1. Familiarize Yourself With the Mobile Application

Before starting the actual testing, it is recommended that the testers go through the requirements of the mobile application, the developer’s documentation, and stakeholder meetings to get a gist of the application. All the testers working on an application should know the functionalities and their purpose of existence to script down in-depth test cases in the future that focus not only on technical aspects but behavioral aspects as well.

2. Create a Test Plan

Creating a test plan is the first step in finding phone bugs, especially hidden ones. A test plan is a document that will lay down the groundwork for the next steps in each area of testing. For instance, what tools to use, what types of testing to be explored, deadlines for each testing, etc. A plan should be documented by keeping in mind that in the future, when the team members are stuck, they will always reference this document.

3. Separate Manual and Automation Test Scenarios

Once the test plan is created, the scenarios written in it cannot be fed into manual or automation testing tools directly. To save time, the testers need to separate these scenarios into manual and automation. Then, those that are manual can be sent to the manual testing team, and similarly, automated ones can be sent to the automation testing team.

4. Perform Manual Testing

The first type of validation to perform is manual testing. This process involves testing mobile applications using human intervention to find bugs. This is performed before test automation. If there are manual testing scenarios that require repetitive work, they can be moved to automation. There can be instances where a scenario may be perceived as suitable for manual testing but found to be better suited to automation once testing has started.

Manual testing focuses on areas such as user interface and experience, which are hard to code. Its main objective is to point out errors that can only be identified by a human such as touchscreen responsiveness on various screens or viewports.

5. Perform Automation Testing

In automation testing, testers write the automation scripts for all the areas defined in the test plan. These test scripts cover each module and functionality for testing.

The scripts written in the above phase are executed to identify the phone bugs. These scripts are reused each time there is a new change in the application. This keeps the old code stable and compliant with the new code.

Automation testing requires mobile app testing tools that facilitate the testing process. For instance, Appium is a cross-platform framework that can help with script writing, initiating simulators, and executing tests on the application. However, the only challenge a tester may face in using such tools is the presence of real devices to run the mobile application. For this, a cloud-based platform with framework support is the best available option.

6. Opt for a Cloud-Based Platform

Procuring real devices is essential for finding phone bugs accurately. Simulators and emulators are great for user interface bugs, but when it comes to performance testing, load testing, network testing, etc., a small difference of a few milliseconds in the metric plays a crucial role.

But the challenge is, that procuring real devices and managing them on-premise is a tedious task. A better option is to use cloud-based testing platforms like TestMu AI and get all these devices.

TestMu AI is an AI-powered cloud testing platform that provides real devices and a complete infrastructure for testing mobile applications on a real device cloud. It integrates with multiple third-party frameworks, such as Appium, through which the testers can execute tests written on these frameworks using TestMu AI.

7. Run Performance Tests

The performance of a mobile application plays a vital role in creating an impression on the mind of the end-user. For instance, consider the loading time of the page once the user has clicked on a button. This has a large impact on the user experience as they observe this behavior explicitly and remember it for a long time.

Performance testing contains many different sections and to perform it swiftly, here too, it is recommended to use real devices and a cloud-based platform that has expertise in the same area.

8. Understand Analytics

A bug may not always appear explicitly through testing and by performing different actions on the application. Sometimes, they are hidden, but their impact is visible in the metrics and user behavior. For this, testers must follow analytics and analyze user’s behavior to find certain patterns that will lead us to the bugs.

A simple example in the eCommerce space can demonstrate this further. Consider you are analyzing the monitoring tool’s reports and analytics for the day. You realize that there have been no Cash on Delivery (COD) payments today.

However, further investigation shows many users have clicked on the COD button but they finally opted for any of the other pre-payment methods. This could possibly be a bug in the application. Now, the tester can replicate these steps manually on the production version and observe the anomalies with the COD button. Such inspections are crucial in maintaining a healthy application.

9. Perform Beta Testing

Beta testing is an effective way of gathering a few customers and letting them use the mobile application before it is published on the application hosting store. The objective behind this is to get feedback from a user’s perspective without risking the reputation of the business with real end-users.

Testers running beta tests help expose phone bugs that a tester might have overlooked. Beta testing also helps understand the user behavior, how they navigate through the application, and what they expect at which place, which ultimately boosts engagement and business revenues.

10. Create a Feedback Cycle

A feedback cycle is a streamlined process between various teams and individuals that make any contribution to the feedback process. It includes the end-user who provides feedback, the tester who is the first person to categorize the feedback as bug, feature, or enhancement, the stakeholders who discuss the relevance of the feedback and whether it should be implemented, and the developer who implements the code.

A streamlined feedback cycle does not directly find phone bugs but provides a platform for the testers and users to propagate their concerns, which, in most cases, turn out to be bugs. It is an indirect but effective way to find bugs in the mobile application.

11. Segregate High-Priority Bugs

Bugs are categorized into various categories during logging or implementation out of which high-priority bugs are of primary concern to the team. For instance, the following types of bugs can be dropped into the high-priority category:

• Bugs that are of high severity.
• Bugs that have a huge business impact (with respect to costs or functionality).
• Bugs that repeatedly appear even after the fix.
• Bugs that may reciprocate to other parts of the code in the future.

These types of bugs are given more priority because they have a larger and more visible impact on the user and can cause major hurdles in the user experience and business revenue.

If a tester checks out all the steps mentioned above in the same order as defined above, they can recover the maximum number of phone bugs in the application and enhance the application quality.
