What Is the Difference Between Vulnerability Scanning and Penetration Testing

Software testing and Quality control aim to provide users with secure applications, safe from any potential hacking scenario or accidental leaks. And to accomplish this, we rely on two security testing methods: Vulnerability scanning (VS) and Penetration testing (PT). While both have a similar role in creating a stronger, more secure system by preventing any breaches/crashes that may occur in the future and threaten software security, there are specific differences that we need to investigate between the two. The Q-Pros Software QA strategy sets out to consolidate the foundation of any system to produce a better swift and secure digital experience through various methods. This article will examine the major differences between Vulnerability scanning and Penetration testing. First, let us start by defining each...

Load Testing Vs. Stress Testing

In the software quality assurance field, two terms seem to stick out the most, “Load & Stress” - It is on any client’s top priority list to make certain that their application can handle larger levels of usage and maintain all factors of quality. Our methods at Q-Pros guarantee that software applications are set and ready for extreme scenarios for future users. In this article, we will investigate and differentiate the two tests we conduct to eliminate the possibility of such malfunctions as overloading and stress, which cause the application to either stop performing and crash, or to perform slower and force users to uninstall the application altogether. What is Load Testing? A load test will help us understand how an application behaves under expected loads. In other words, it allows us to monitor the overall performance of the application under the basic demands of real users. Load testing is not concerned with overusing the application, but it is all about measuring the performance stats under what is expected of the application. This is done via requesting several demands from the application and then investigating the speed at which it accomplishes its required responses. Load testing helps determine the bottlenecks of applications. Load testing comes in handy in certain periods of the application's usage. For example, your application might have a standard number of users most of the time, but it is not until there is an update or an offer in which will cause the number of users to spike up, take for instance a government portal in which there was a certain event that caused citizens to suddenly request an official paper, or a shopping application on black Friday. Having a good testing foundation firsthand allows you to prepare for all kinds of circumstances, and it will guarantee an increase in ROI (Return of Investment). What is Stress Testing? Stress testing allows us to identify the breaking point of the application. Breaking points are the maximum level of load an application can endure before failure. The benefit of stress testing is not only to inform companies of their application’s limitations but also to make use of such results and scale up the application based on the data gathered from stress testing. For example, knowing the breaking points allows developers to make certain changes in the application's behavior before the breaking point is reached to allow for adjustments and adaptation and avoid extreme results. This in return evaluates the robustness of the application. Stress testing is necessary for developers to know what features break first in case of extreme stress. Knowing that will help them act accordingly to make sure that no permanent crashes occur and to limit the possibility of catastrophic events. What are the differences between Load Testing and Stress Testing? Load Testing is more of an organic approach. It is not concerned with breaking the application as much as it is concerned with finding out if the application has covered its basic requirements of handling the expected levels of load. Load testing is essential for companies because it asserts confidence in the application in case of future challenges. On the other hand, Stress testing is mainly concerned with finding an application's upper limit. Stress Testing helps us determine where the application is most likely to have some sort of failure, and by doing so, it evaluates the robustness of the application. Stress testing also allows developers to enhance the application's behavior by knowing how it will react in case of failure due to maximum usage. Both load testing and stress testing are essential for companies, especially when dealing with bigger service applications that will require more usage and constant maintenance/updates.

Difference Between Component Testing and Unit Testing

Understanding the hierarchy of testing is elementary for QA practices, it helps us keep all activities coordinated with one another and stabilize what could be a long and tedious procedure. For that reason, we at Q-Pros have established a constructive approach for software testing to make sure our clients get guaranteed results. In this article, we will look at the differences between Component Testing and Unit Testing and identify the specific comparing basis to distinguish the two essential levels of testing. To begin with, we will start by identifying each method individually. What is Unit Testing? Unit testing is a software testing method which takes every unit of code into consideration for testing, to make sure that all code-sets are appropriate based on requirements and standard suitability before stepping further with the code building. Computer data is examined to check if it fits or not. This is done to completely avoid any future errors that may become hard to detect if not dealt with sooner. Unit testing is done by the developers, and it comes first in the hierarchy of testing levels. What are the testing levels for software systems? Unit testing: Unit testing takes top priority before stepping further into code. Integration testing: Modules are combined and evaluated as one with specified functional requirements. System testing: In system testing, we take all the integrated components that passed the test as input. Acceptance testing: Finally, we measure the degree to which the application has met the user’s approval. In Unit testing, the word “Unit” means every element within the application that could be tested during the development stage. What is Component Testing? Component testing also referred to as module or program testing, is a test where each component of the system is tested individually without looking at integration in-between other components. Each component receives an input, and then the data should be processed through the system and produce an output. This output will be examined based on requirements separately. The main objective of this type of testing is to make sure that all components within a system are user-understandable and can be used individually. Component testing is usually done by a developer before creating a new component. Developers can choose to move to build a new component once all identified defects are fixed in a previous one. Developers use this method to examine testing objects without integration, meaning that testing objects are tested separately from the whole design or any other components or modules. The Differences between Component and Unit testing After we have defined the two types, we can now start to look at each in comparison to the other to get a further understanding of how we can relate them in an overall testing strategy. We will now look at key factors to differentiate the two kinds distinctly: Comparing FactorUnit testingComponent testing ExecutionUnit testing is processed by the developers in the initial stagesComponent testing is performed by a team of testing engineers using various testing tools. Method usedWhite-box testing: Testing the application with knowledge of internal structures.Black-box testing: Testing the application with little to no internal knowledge of its code. ValidationValidates the efficiency and accuracy of the design documentsUses test cases and validates specific components. Detecting error Unit testing detects errors more easily.Component testing detects errors with more complexity than unit testing. Level of TestingUnit testing is performed at a granular level.Component testing is performed at the application level. Unit and Component testing are fairly related, both require a level of segregation from the overall system. Component testing is done on an application level by testing experts, On the other hand, unit testing is done on an agranular level by developers. It is also worth highlighting that component testing can only be done after unit testing. Q-Pros Constant updates require constant testing.
