Functional Testing

What is Functional Testing? Know the Top Functional Testing Tools?

Nowadays, Functional Testers are the show-keepers of almost every business. Rising businesses are making big investments in QA and Test management services where functional testing keeps the topmost importance in the process. Though due to few reasons and revolution in technology, QA engineers begin to consider Functional Testing the subordinate of software testing. It can’t be right!

Because every day thousands of applications are developed and launched in the market, which makes it easier for the users to switch the old ones and shift to the new ones. It is frightening, but this is what happens these days that if users find something superlative in some other app, they won’t mind shifting to that app in an instant.

Consequently, it can be said that a single glitch appearing in your app takes it down in a matter of minutes. At the end of the days, it’s the customer experience and super-smooth app functioning that matters.

Importance of Functional Testing and Tester

Functional Testing is the forte of QA testing and management. So, imagining the completion of SDLC is totally unruly without getting a pro functional tester involved. A functional tester approaches quality in the product at the risk-based criteria. He/she prioritizes test cases that are of more significance with a link to the business requirements and expectations in term of success and profit gain.

How Does Functional Testing Work?

The functional tester incorporates specific input-driven data blocks in the test cases, as a result, pre-decided techniques are executed to determine the anticipated output. The input is actually the expected requirements while the output is the fulfilled requirements.

Hence, testers validate the results and see if the output driven matches the desired functional features. This mechanism ensures the whole QA team if the app is durable enough to keep its users engaged and entertained. It essentially intensifies the overall product quality.

So, stop making excuses to abandon functional testing because it’s still running the show for the QA teams!
Functional Testing Types and Purposes

Following are some of the majorly used functional testing techniques that are letting business beat the overriding competitors in the race:

Unit Testing – To Test Each Feature

Every test step or phase you cover requires in-depth scrutiny. Thus, unit testing lets testers verify each test unit and code throughout the software development cycle. Testers, as well as developers, are responsible for assuring the product’s quality to the baselines. To create an almost correct and error-free application unit testing is executed that gives way to maximum test coverage.

Unit Testing is subdivided into categories: Statement Coverage, Function Coverage, and Path Coverage. These activities are chiefly implemented according to the type of test coverage required.

Meet your Goals with Functional Testing

The major one, functional testing lets the testing team, as well as the stakeholders, assess if the generated yield counterparts the functional requisites. It is wholly linked to creating a customized test environment that is focused on delivering the expected results in the end.

The black box testing is a sub-type of functional testing through which businesses get to know the position of their product by estimating the outcomes obtained through the testing process.

System Testing to Reach Business Objectives

System Testing refers to end-to-end testing. It sneaks into the interlinked and cross-sectional software units and blocks. It lets the testing teams calculate the benefit of all the functional features combined together for the final product.

System testing entails the recognition of all those missing features and units that could better the product quality and delivery.

Regression Testing to Maintain

Regression testing is a prime component to stabilize the software functioning and performance even after a change is made or a module is added in the system’s framework.

By large, regression testing plays an important in maintaining the product quality and workflow without letting a change or entity disturb its performance. It should be periodically executed to ensure the business development model and other software patterns.

Stay Aware with Smoke Testing

With smoke testing testers can get an idea of the severity of bugs and what testing approach would it require fixing these bugs. In this type, testers do early testing of software’s units to extract out threatening errors. In simple words, smoke test type is indicative of the dangerous fumes that might have a dense concentration of errors under the hood.

Sanity Testing

Sanity Testing is highly sane and logical. In this, testers trust more on their intuition and tester instinct. On the basis of logical analysis of the test project, testers predict and take beneficial decisions for the success of the product. It lets testers decide what testing technique should be implied on a specific bug keeping in view its severity and threat.

There are many other testing techniques as part of functional testing that has the ability to scale up any business and enterprise. These testing practices are UX testing, User Acceptance Testing, and System Integration Testing etc.
