Software Testing metrics are quantitative steps taken to evaluate the software testing process's quality, performance, and progress. This helps us to accumulate reliable data about the software testing process and enhance its efficiency. This will allow developers to make proactive and precise decisions for upcoming testing procedures.What is a metric in software testing metrics?A Metric is a degree to which a system or its components retains a given attribute. Testers don't define a metric just for the sake of documentation. It serves greater purposes in software testing. For example, developers can apply a metric to assume the time it takes ... Read More

Software testing is the process of evaluating and verifying a software program to ensure that it functions properly. The goal is to identify flaws and enhance product quality. There are two methods for testing software: Positive Testing and Negative Testing.Positive TestingPositive testing is a sort of testing that is conducted on a software program using legitimate data sets as input. It determines whether or whether the software program acts as predicted when given favorable input. Positive testing is done to ensure that the software program accomplishes precisely what it is supposed to accomplish.Example − In an app, there is a text ... Read More

Tests are generally classified on where they are implemented in the SDLC or the degree of information they include. There are four types of testing overall: unit testing, integration testing, system testing, and acceptance testing. The goal of Levels of testing is to make software testing more methodical and to make it easier to discover all feasible test scenarios at a given level.There are several testing tiers available to aid in the evaluation of software behavior and performance. These testing stages are intended to identify gaps and reconcile the development lifecycle phases. SDLC models define stages such as requirement gathering, ... Read More

You will learn the following in this article −What is Design Verification?Difference between Design Verification and ValidationDesign Verification ProcessDesign Validation ProcessAdvantages of Design Validation and VerificationDesign ValidationDesign Validation is the process of testing a software product to ensure that it meets the specific needs of the customer or partners. The goal of design validation is to check the software product after it has been developed to confirm that it fits the criteria for implementations in the user's environment.Validation is focused on establishing the design's accuracy and reliability in relation to the user's demands. This is the step in which you ... Read More

Conformance TestingConformance testing is a software testing approach being used to ensure that a software system meets the guidelines and requirements set by IEEE, W3C, or ETSI. Conformance testing determines how well a system undergoing assessment verifies to fulfill the specific needs of a certain regulation.Compliance testing is another name for conformance testing.It may deal with certain technical aspects, but it incorporates the following on purpose −PerformanceFunctionsRobustnessInteroperabilityBehavior of systemYou will learn the following in this tutorial −What is Conformance Testing?Types of Conformance TestingWhy do we need Conformance Testing?What do we need to test?When and how to perform Conformance Testing?Conformance Testing ...

In this post, we will understand the difference between top-down integration testing and bottom-up integration testing −Top-down Integration TestingIt is also known as incremental integration testing.The higher level modules are first tested after which the lower level modules are tested.Once it is done, they are integrated.The higher level modules are the main modules and the lower level modules are the submodules.It uses stubs to simulate the sub-modules.If the sub-module hasn’t been fully developed, the stub acts like a replacement to it.It is useful in cases where significant defect occurs at the top of the program.The main module is designed first ...

Spike testing is a type of performance testing used to determine an application's behavior when exposed to extreme traffic variations. In spike tests, the app is revealed to sudden decrease and increase in load. The results are then analyzed based on factors like −Does the app crash?Does the app slow down?How long it takes the app to switch back to normal?Accumulating test results, the developers determine when and where the application fails and then take necessary actions for performance improvement.Example of Spike TestingLet's say X University is all set to upload the results on its official site at 1 −30 ...

Soak testing is a non-functional performance testing under which an application is exposed to a continuous load for a pre-determined period. It is also known as Longevity testing and Endurance testing.The term 'soak' itself explained the test's purpose. Let's consider yourself pulling a rope on one end while your friend pulls it on the other end. Now, if you pull it for one hour, it won't affect the rope much. However, if both of you continue to pull it for days, the rope might eventually break.The same rules apply to software as well. When software faces a high load, it may ... Read More

A tester measures an app or site performance by collecting various data during a load or stress test. However, every test starts with sending a request to an application. Once a request is sent, the tester calculates the app's response time by estimating how much time it takes to respond to the specific request. Let's understand response time with real-life examples −Offline exampleLet's assume you are standing at the checkout counter of a grocery store. The cashier takes three minutes to process the products. Now, if you have a lot of customers waiting in front of you, that means you will ... Read More

The word 'reliable' means something that is 'dependable' and 'trustworthy.' In other words, a dependable product lives up to its expectation regardless of how much we use it. In software testing, Reliability testing is a process to know whether software can perform as expected under a given environment. Reliability Testing ExampleLet's say you are a graphics designer. So, you may need a PC to run for at least 7-8 hours per day with its full capability without crashing. Reliability testing is the process that can determine whether the PC you are about to purchase can works flawlessly for long hours or ... Read More
