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 other 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 important 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 a program’s essential functionality is checked and ready for additional testing. It prevents a QA team from performing a thorough test on software that can’t execute basic tasks. ZappleTech wants to ensure your project success with smoke
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 entire testing of the application and its interaction with other apps, simulating use of the product by the customer.
Regression testing
The goal of Zappletech is to catch any faults and verify that previously eradicated defects cannot be recreated.
Black box testing
We provide black box testing to see if a new version of the program has a regression or a decline in capabilities, from one version to the next.
Manual and automated testing methodologies
Various strategies and approaches are used to test an application to ensure it behaves and looks as expected.

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 an 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 test case construction.

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.

Because I'm lazy and easily bored, I tend to automate everything I can, if I need to do something twice that is a good indication that something
is off. My automation experience suit includes mobile, gherkin, web, C#, Java, JavaScript, C++, Ruby, and multiple frameworks. I do coding and
“DevOps'ing” too because I gain most of the value not deep-diving into one framework or discipline, but generalizing in the whole spectrum of
software engineering. This generalist point of view allows me to see some issues from different angles and come up with more solutions to solve problems.

I began speaking in 2018 at CodeMash in Sandusky Ohio where my first talk How Pro Wrestling Made Me A World Champion Tester put me on the proverbial map.
Since then I’ve given far more serious talks at conferences like TestBash and Star. In 2020 I was a keynote at STARWest Virtual testing conference and I was on the selection
committees for STARWest 2021 and Agile Testing Days USA as well as host for TestBash Home 2020 and 2021. I am an occasional tech blogger, trainer, product owner, and
always a tester, but the accomplishments I’m most proud of are my ordination as a deacon at South Euclid UCC in 2016 and my long and happy marriage to my spouse for
the past 11 years.
