The term 'Harness' in general refers to a 'Tool' for controlling something. The same rule goes for software testing as well. In Software Testing, Test Harness is a collection of software, test data, test drivers, and tools specially developed to test an application under various environments. Developers then analyze the results of the tests to ensure a satisfactory outcome.How is Test Harness done in software testing?Test Harness can be called a process that does all the testing works, such as executing tests via test libraries and generating reports. For that, developers and testers have to develop specific test scripts to ... Read More

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
