Functional testing services we provide:

When you hire a functional testing organization, you’re almost certainly signing a long-term contract. We start with the first implemented feature and work our way through the app’s completion and the first user. Today is a free consultation. Let’s discuss our cooperation!

Feature testing
Every new feature you add and every change you make improves your product, setting it apart from similar items on the market. At the end of each iteration, we provide feature testing to ensure that the functionality implemented in the current build is correct.
Full system testing
When your product is ready for release, we focus on evaluating the application’s end-to-end flow, not just individual features. Every user scenario is validated from the perspective of the end user, ensuring that the functionality matches the specification criteria.
Regression testing
Regression testing is an essential phase in product development that ensures that recent code modifications haven’t caused any issues with the existing system. We use test automation techniques to re-execute previously completed test cases to provide regression testing.
Automated functional testing
It’s possible that you’ll need to speed up your testing to keep up with your short development cycle. When establishing important, repetitive, and complex test procedures, we automate functional testing to save time, decrease expenses, and boost efficiency.
Smoke testing
Our goal is to verify that the basic functionality of a program has been checked and that it is ready for further testing. It prevents a QA team from performing a thorough test on software that can’t perform basic tasks. ZappleTech wants to ensure the success of your project with smoke testing.
User acceptance testing
Zappletech’s main objective with this automation type is to confirm end-to-end business flow. It doesn’t care about typos, misspellings, or system testing. User Acceptance Testing is done in another environment using data that is comparable to what is utilized in production.
why our services
End-to-end Agile testing
End-to-end testing with Zappletech implies the entire testing of the application and its interaction with other apps, simulating the use of the product by the customer.
Regression testing
Zappletech’s aim is to be the source of all defects and to verify that defects which have already been eliminated cannot be reproduced in a comprehensive manner.
Black box testing
We apply the blind search principle to investigate the mutual compatibility between old and new code fragments, modules, and revisions.
Manual and automated testing methodologies
We use a comprehensive approach to the QA tasks of the project. We combine all existing techniques to improve the IT resource’s overall UX and error control.

What is functional testing and how does it work?

Recognize the requirements:

The first stage in the functional testing process is to have a comprehensive understanding of the business requirements. This is a critical stage in ensuring the success of subsequent steps.

Prepare a test plan:

A good test plan is essential for successful functional testing. Test engineers must work on the test objectives so that scheduling and organizing test operations becomes easier.

Create functional test cases:

After analyzing the requirements and creating a test plan, another crucial step is to create functional test cases. Test data, test input, and test output are three significant factors that must be addressed here.

Create input data based on requirements:

In order to test specific functionality, testers should create data and use it as input to test the application’s functioning. This form of data is referred to as input data, and the data used to test applications is referred to as test input data.

Execute test cases:

The next step is to run the tests using the test input data that was identified during the meticulous test case construction process. This ensures thorough coverage and accurate validation of the system’s functionality and performance.

Compare the actual and expected results through result validation:

This is the most important stage, where the actual test output is compared to the expected test result to determine whether the tests are passed or failed.

When comparing actual and predicted outputs, log faults are defined as the variance of the difference found between them. Defects are reported by testers to development teams so that they can be fixed as soon as possible.

Frequently Asked Questions:

A functional test is used to determine if all of the system’s or units’ functions are as expected by the user. It entails comparing the software to a list of the functions it was planned to accomplish (a specification) to verify if it performs as expected.

Functional testing focuses on a specific feature of a product. It verifies that a feature meets a set of product requirements. System testing, on the other hand, seeks to test the entire product from beginning to end.

Functional testing, product usability, performance, security, and scalability are all examples of system testing. In other words, functional and non-functional testing are both included in system testing.

What is non-functional testing, and how does it differ from functional testing? Non-functional testing examines all parts of a system that aren’t covered by functional tests. It comprises the software’s performance, usability, scalability, and dependability. We perform non-functional testing to ensure that the end-interests user’s are protected.
