Software Functionality Testing: Proven Ways to Set Up Your Design for Success

4 Mins read

The new software you’re creating will function well and be as easy to use as possible, right? Anyone who’s creating great easy-to-use software applications knows there are many steps in the design process. This includes everything from initial goals and purposes to user interface (UI) layout and user testing.

One of the most important steps in the software design process is software functionality testing. In today’s highly integrated world, software must meet many user demands. Users want software that is fast, integrable, powerful, and easy-top-use.

Software functionality testing is a method of testing software against the required specifications for the software. The purpose behind this testing is to ensure the software you’re creating accomplishes the intended goals. Testing also helps check the user-friendliness and compatibility of the software.

Are you in the testing stages of your new software? If yes, you must check out these proven ways to test the software functionality of your design!

Understanding Software Functionality Testing

Software functionality testing is a method of testing that tests each function of the system. The purpose of this testing is to ensure the software meets the expected requirements and specifications.

The test works by you or another tester providing input and expecting a particular output. When you receive the actual output, you’ll compare it to the expected output. It focuses on the process by simulating how others will use the system and verifies each function.

Functionality testing checks:

Designers and engineers can perform the functionality testing manually or automate it. There are many different types of functionality tests you can perform throughout the course of the development process. You should repeatedly test and re-test your software in every stage as it develops.

Automated Versus Manual Testing

The two main ways you can perform testing is manually or with automation.

Manual testing refers to a human using the computer software to carefully performing the tasks and test steps. This option works well but tends to cost more and takes extra time. You will need some manual testing at the very beginning of the software development and the very end.

Automation testing uses automated testing software to perform a test. The testing software can enter data, compare expected and actual outputs, and create test reports. Automated testing gives designers and developers the option of recording the test and replaying it for reference later.

Automation testing is a great option for those who need to save time, want greater Test Coverage, and results in fewer errors. Automation testing is best for designs needing repeat testing and those that are tedious or challenging to do manually. Other cases include business-critical and time-consuming tests.

Types of Software Functionality Testing

The best software developers perform different functionality tests throughout the software development cycle. There are various types of tests you can run. There’s also the option to run these tests manually or automatically.

Smoke Testing

This is one of the first tests performed on a new build of the software. Smoke testing tests the basic functionalities, focusing on the most important components of the design. The goal is to ensure the software at this stage can complete its main functions without any issues.

Component Testing

As designers and developers add more components and modules, these will need testing, too. A component is a smaller part of the software and includes parts that take inputs or offer outputs.

Component testing focuses on testing components independently to ensure their usability and functionality work properly.

Unit Testing

Unit testing focuses on the code portion of the component. As it tests to ensure the component offers the expected output, unit testing will perform a standalone test of the code.

A major benefit to this type of testing is it finds weak areas in the code. You’ll be able to edit the code and present any future issues in later testing.

Integration Testing

Integration testing is one of the more common types of functionality tests. It tests individual components as they function together with other components.

Integration testing treats the components as parts of a whole system. It will spot any issues with the UI, data formats, API calls, operation timing, and user interface operation.

Regression Testing

Throughout the development of the software, you and your team will need to make some modifications. When you make changes, there’s a big possibility that they could cause other issues or unexpected behaviors.

Regression testing tests the modifications. These tests ensure previous issues don’t persist and no new issues popped up.

Sanity Testing

If a new build underwent testing and received modifications, a sanity test will test those modifications. The test will check that the changes made fixed the original problem and didn’t cause any other issues.

Sanity testing is a set of tests and a branch of regression testing. Many people confuse it with smoke testing but sanity testing focuses on the modifications and not the entire unit.

System Testing

System testing tests the software and all of its components as a whole. The purpose of this test is to ensure the system meets the functional and technical requirements. This step happens after all the components of the software successfully pass the integration testing.

Individuals who haven’t played a part in the design or development of the software will test the product. The testing environment closely resembles how end-users will use the software system in the real world.

User Acceptance Testing

The final testing phase a software product must undergo is user acceptance testing (UAT). Actual app and software users will test the software to check that it can complete real-world tasks. Most companies will use this as the final test and will show it to stakeholders upon the software delivery.

Create Your Best Design with Software Functionality Testing

Software functionality testing plays a valuable role in the design and development of a product. Using these tests throughout the development process will help you create a product that’s easy to use and free from functional issues.
