Functional Testing: Best Practices to Consider

Nov 16, 2022 | 42Gears Team

Mobile app functional testing is one of the most important ways to make sure that apps work as they were meant to. Functional testing is different from other testing methods because it is done from the point of view of your app's end users. When functional testing is done right, it can help find and fix software bugs while improving the end-user experience.

To make sure testers carry out functional testing effectively, we have compiled some of the best practices for functional testing, which you can apply in all environments. 

1. Know your requirements for testing

Having clarity on what needs to be tested will help you develop a robust test plan and case. Analyzing the system requirements can help you cut down on mistakes, errors, and failures, especially when planning the test. 

2. Develop a comprehensive and detailed functional test plan

A good functional testing strategy includes the test's goals and parameters, the people, software, and hardware that will be needed, and a time frame for the test. You can also prioritize and rank the test cases that will be created as part of the strategy. 

3. Determine which portion of the plan can be automated

In an already established formal testing procedure, test automation can get rid of repetitive tasks while reducing time-to-market. It provides extra testing iterations that would be challenging to carry out manually. Automation often makes it easier and more efficient for Quality Assurance (QA) teams to find and fix app bugs. However, it is important to note how much to automate because, in some cases, manual testing may yield better results. Moreover, test automation is more expensive than manual testing. Therefore, you must choose wisely.

4. Carry out functional testing in an actual user environment.

When the development team develops mobile apps, it’s important for testers to dive deeper and check if an application and its functionalities work in all user conditions. 

5. Manage defects with appropriate sophistication

Typically, most testers use an issue-tracking system to centralize the test repository. With this, quality analysts can find, record, report, manage, and track bugs efficiently.

But the issue tracker isn't likely to be enough when there are many configurations, different workflows, and multiple data sets. In such cases, a robust mobile test management system could be very helpful for functional testing.

6. Manage test results in a simple way

By deploying an effective test management system, quality analysts can easily create an abstraction and presentation of test results. Previously, people used an Excel-based system to manage functional testing reports. It used to take them hours or even days to create a complete report. It is important for testers to deploy tools based on their operating environment. For example, if you use a traditional system in an Agile setting, it won't work well.

Therefore, no matter which system you choose, the reporting component should keep the development and management teams updated about the status and progress of testing.

7. Analyze your test metrics

You can use software testing metrics to estimate the progress, quality, productivity, and health of software. Testers should analyze and highlight problems and opportunities in both the development and testing processes. The goal of using metrics tools is to make the functional testing process more efficient and effective and to help people make better decisions by giving them accurate data about the testing process.
