Overview

We are living in a high tech age. This blog is gonna help you know about some of the most important basics of this topic. There are numerous segments to be studied in this topic. We are gonna try to be as to the point as possible and facilitate a perfect guide to such tools and their capabilities. So let us delve in quickly guys !

What is Functional Testing?

The requirement or functional specifications aid in defining what QA engineers think acceptable when running functional tests are performed. These common specifications are basically a document which tells the QA engineers exactly what actions they should take to fix the actual conformance of the software management system. This document can even ask them to perform tests on particular business side scenes for a total system process.

And so we know that QA engineers can perform functional testing in two different ways:

Needs-based functional testing is the technique containing instructions regarding the validation of the functional aspects of the software systems.

Business scenarios-based functional testing is the method that includes instructions regarding the validation of the software system put on business scenarios.

What do you test in Functional Testing?

Testers fundamentally perform functional testing to verify and check about the functionalities of the software system. The segments this testing focuses on are:

Fundamental Usability: This test performs a usability test to know that users who are navigating your system are doing so in a  seamless manner.

Accessibility: Performs accessibility checks on the system to check if it fulfills accessibility needs.

Prominent functions: The system does not have value if its important functions do not perform well. This testing is done to ensure to eliminate the chances of such occurrences.

Error Conditions: Whenever there is a mistake, the system normally renders a precious error text. This test is performed to validate that the system functions well and gives the perfect error signals to debug.

What Are The Different Functional Testing Types?

There are various types of functional testing. Here are a those, let us analyze :

Unit Testing

Developers run unit testing. The developers draft test scripts which help testers find out if individual units of a software system fulfill particular needs. Basically, this has the developer writing tests which verify each unit technique and confirm these units fixed on the brought back values.

Code coverage is a necessary aspect of unit testing. When you are actually running a unit test, confirm that the test cases includes the following:

• Code path coverage
• Method coverage
• Line coverage

Smoke Tests

Smoke testing, even known as build verification testing, confirms your build’s stability and testers perform it later when each build is released.

Regression Tests

Regression tests confirm that the software system is stable and functions as per the requirements even at the time when developers fix bugs, put new code, or make improvements. You don’t need to perform regression tests as outstanding as functional tests. However, you must make sure that your test must help you validate that your system’s functionality is highly stable.

Sanity Tests

Testers run sanity testing to confirm the perfect working of all important functionalities which are in your software system. Testers normally run sanity tests when smoke tests are done.

Integration Tests

Integration tests even help ensure the system’s functionality when there are numerous modules. These modules will work nice when single, however, can the modules function seamlessly to validate an end-to-end scenario when brought together? Integration tests aid to reply to this question.

Usability Testing

In usability testing, the system provides real users reach to their product and permits them to function tests on this. This test objects to know how the users enter in interaction with the product and whether they are comfortable while using it. The system uses the feedback to have improvements where essential.

Must have Functional Testing Tools

Functional testing is actually significant in the software development designs, confirming that the software’s character is as expected and fulfills the customized requirements. Several functional testing tools have been created and designed to make this process convenient, each with outstanding strengths and features. This section unravels some of the most famous and efficient functional testing tools open to testers and developers.

1.TestComplete

TestComplete is a total automation testing system supporting mobile, desktops and other significant web apps. It provides a strong interface that paves way for testers to design automated tests without deep programming information. TestComplete aids different scripting languages like Python, VBScript and JavaScript and renders technologically advanced abilities for editing, recording and performing tests. Its capability to link with other frameworks and tools improves its use in a complicated testing ecosystem.

2.Selenium

Selenium aids several programming languages that allows testers to draft test scripts in some of the best languages. Selenium WebDriver, a part of Selenium, makes automated testing to be performed on different web browsers. Its adaptability with several browsers and functioning systems makes it a perfect choice when it comes to functional testing.

3.Cucumber

Cucumber permits the features of application programming in plain language. This even makes it convenient for stakeholders, that includes those who are without any technical backdrops to know the tests. Cucumber aids different languages, that include Java, NET and Ruby and interlinks with popular functional tools like Selenium and other important testing frameworks to make full fledged functional testing easier.

4.JUnit and NUnit

JUnit and NUnit are those frameworks utilized for unit testing in .NET and Java surroundings. While they are basically created for unit testing, they can even be utilized for functional testing by interlinking them with other important tools. These highly popular systems enable behavior-driven development, test-driven development (TDD) and facilitate more efficiently used and structured testing procedures.

5.QTP/UFT (Unified Functional Testing)

Designed by Micro Focus, UFT is actually a financial support and functional testing system tool. It helps different desktop, web and mobile apps and provides an amazing visual interface that makes test development and execution convenient. UFT links seamlessly with other Micro Focus system tools, rendering a perfect solution for enduring integration and testing.

6.Postman

Postman supports the functional testing of various web services. It renders a perfect user-friendly interface to share requests to web servers and even study responses. Postman helps automated testing via collection runners and scripting that makes it a precious tool for testing the functional behavior of RESTful APIs and other important web services.

Advantages of Functional Testing

• Functional testing produces the product in live weather, and its main aim is on the functional system, system features, browsers and more.

• Functional testing does not function on hypotheticals and integrates explicitly with the system’ structure.

• Firms can give top notch products via this testing methodology.

• It facilitates them to meet customer needs and brings in customer delight.

• This exam aids firms to give a bug-free product and that which meets all the client requirements.

• Risk-based testing facilitates a reduction in risks.

Bottom line

We have studied some of the most important features and importance of functional testing. We hope to have dealt with the topic in the most efficient way. Functional testing can be studied in a much deeper manner but we are sure you have picked up some great knowledge from here.
