What is Functional Testing? As part of the Quality Assurance process, functional testing is a testing prerequisite for assessing precisely how the system functions. A system comprises of several components that must all work individually, and also mutually, for robust functioning. These aspects must be verified through in-depth functional testing. In functional testing, each component is first tested to confirm if its desired output is as per code, and then doubly checked to ensure that…

What happens typically in a Functional Testing scenario? In this back-box testing type, various functions are put under test with certain inputs, where their output is checked and measured for accuracy and effectiveness. Software Functional Testing is very much critical for software application development, as it helps to check the software’s dependency much before it is finally deployed for the users or across the IT infrastructures. Weighed on similar lines, Performance Testing and Functional Testing…

Functional Testing Vs Performance Testing: Differences between Performance Testing, Load Testing and Stress Testing were explained with examples in our last tutorial. Software Testing covers a wide range of areas where any verification or validation of software functionality can occur. Occasionally, non-functional aspects become less concerning the functional aspects. They are not performed practically; simultaneously during software testing. Quick difference between Performance Testing and Functional Testing Sl NOFunctional TestingPerformance Testing1To verify the accuracy of the software with definite…

This article is for those who write or are going to write functional tests for any programs. The goal of this article is to give the flavor of the main techniques of test design and also to answer the question: What method is better to choose for testing your project? My first tests or What are the techniques of test design for? When I began testing I didn’t know any of the techniques of test…

Myopia means nearsightedness. If you write functional tests, you likely suffer from functional test myopia. You focus on your expected outcome and your test coverage, but you miss the big picture. We all know the joke about one night with a guy on his knees under a streetlamp. As he’s fumbling around, a passerby notices him. “Sir,” says the passerby, “What are you doing down there?” “I’m looking for my wallet,” replies the guy. “Where…

What is functional testing in software testing? Functional testing answers the fundamental questions “does this actually work?” and “can the user do what we expected?” This method of software testing tests the functional requirements of an app, verifying whether the software works as per customer needs. Functional testing is not concerned with how processing occurs, but rather, with what the results of processing should be. How to test software functionality There are 6 steps in the functional testing process: Identify and clarify the functions that you expect the software to…

The use of platelet-function tests to monitor and guide antiplatelet therapy in PCI patients has sparked heated debate. Cardiologists have sought to reconcile biological plausibility with the absence of clinical evidence. Now the ARCTIC (Assessment by a Double Randomization of a Conventional Antiplatelet Strategy versus a Monitoring-guided Strategy for Drug-Eluting Stent Implantation versus Continuation One Year after Stenting) trial brings cold comfort to supporters of the monitoring strategy. The ARCTIC investigators randomized 2440 PCI patients…

The RECLOSE 2–ACS (Responsiveness to Clopidogrel and Stent Thrombosis 2–ACS) trial from Italy provides new information about platelet reactivity but doesn’t answer any of the key questions about the possible role of platelet function testing in clinical practice. In a paper published in JAMA, Guido Parodi and colleagues report on 1,789 ACS patients who underwent PCI and who had their platelet reactivity measured. Patients who were found to have high residual platelet reactivity (HRPR) received a larger dose of…

What Is Functional Testing? Functional Testing is a type of software testing that verifies that each function of the software application. Each function of the system/application is tested by feeding them input and examining the output by comparing the actual results with the expected results. Functional testing primarily tests the mainline functions of a system. Functional testing includes verifying UI, APIs, Database, and Security. It can be either automated or done manually. What Do You Test…
