In the era of advancement, companies and businesses keep on changing their system, software, and technology to stay ahead in the competition of digitalization. Consequently, adding new features to their services and products helps to enhance their growth and quality. All these steps ultimately generate more demand for their products and more revenue.

Have you ever wondered why Apple has become the world's most famous tech company with its products? Apple releases a new iPhone version every year with new appealing features anticipated by the world anxiously. Thus, people become more interested in their products, which drives them to buy them. Consequently, Apple can upsurge its selling and production power with enormous revenue by executing a few advanced features into its products.

Features consequently play a vital part in Software Development Life Cycle (SDLC). New features mainly set apart a product and make it unique from other comparable products in the market. Even though software developers design viable and appealing features, defined as the progressions that add new functionality or change current features. The developers usually use testing methods like Feature Testing, which guarantees that the client and end client get bug-free products. In this article, we will discuss Feature Testing and its importance in detail.

What is Feature Testing?

Feature Testing is the method involved in making changes in a software system to update at least one or more new features or make some modifications to the current version of the software. These features are known to have unique characteristics intended to be helpful, intuitive, and effective. Therefore, even though testing these features within each development stage is essential, they should be tried thoroughly.

The point of feature testing is to ensure that the product works appropriately to meet all the planned goals and specifications. On the off chance that any product or application can't work according to the client's requirement or execute the picked capacities with exactness, it might prompt a massive loss of money and effort. Perhaps, organizations use numerous software. Thus, the breakdown of any particular program might result in an obstacle to the functioning of other software too.

To remove any existing issue in the software's functionality, it is necessary to do feature testing. The new features and improvements sometimes come with specific bugs and issues, therefore, features testing tracks those issues and selects the best one to continue with.

How does Feature Testing Work?

Feature tests are like A/B/n tests that permit you to control whether, for every variation, the related feature is on or off through feature flags, also known as feature toggles. Likewise, it empowers you to manage the feature variable values for the various parts related to the feature.

Whenever visitors reach your site or application, the feature gathers metrics connected with their engagement with the features. Likewise, you can look into measurements on the analytics dashboard to decide if the feature prompts positive or negative conduct. Simultaneously, you can again figure out what feature setup is the most effective.

Practices to Follow for Feature Testing

Before starting with the feature testing, it is essential for the developer team to aim toward the current application and how the new feature finds a place with the existing features. Although, each feature ought to have a characterized unique function, and the team should record the business necessities related to it.

Moreover, the developer team ought to likewise comprehend how the current features will impact the working of the new features. According to a design perspective, every new and unique feature in the application should work in tandem, firmly running together.

Below are the key steps to doing feature testing effectively-

  • Assemble data on positive and negative cases

Before starting the test, the QA should outline every information case on positive and negative and limit cases to follow errors and bugs in the new feature. By doing so, analyzers can easily play with every positive and negative software that a client could experience and check whether everything is working appropriately.

  1. Information about feature execution

The next step for the team is to attempt to acquire clarity in every one of the areas associated with the feature execution. This would incorporate all the backend changes made to execute the feature. Therefore, it will permit the analyzers to detect an error quickly and make changes if required.

  • Test the form in the beginning phases

Developers should start testing the features during the beginning phases of the improvement cycle. It will guarantee any overall issues that may be experienced after the feature is developed. This will permit developers to settle for the imperfections early and adjust the feature to the client's requests.

Why Should You Do Feature Testing?

Before launching the new features you have developed, it is essential to test them to decide the effect on the clients and application. Therefore, it is essential to perform feature testing to effectively understand the impact of your new features on user experience.

Therefore, mobile application testing will assist you with understanding the business effect of this new feature and what enhancements ought to be made before release.

Testing of New Feature

Before releasing a new feature, it must be tried with real-world experiments. As thousands of users will use the feature, it turns out to be harder to deliver an application with zero error, as each individual is unique in relation to another.

Below are a few essential steps to testing new features for mobile applications.

  • Field Testing

Field testing becomes a significant part of testing the new feature and its effect in real-world situations. This test will be done by QA analyzers where they would involve this integrated feature according to the need in reality.
