What is unit testing?

Unit testing is a software development process in which the smallest testable parts of an application, called units, are individually and independently scrutinized for proper operation. Signup and view all the answers

What is the purpose of smoke testing?

Smoke testing is done as a preliminary check of the software after a build and before a release to find basic and critical issues in an application before critical testing is implemented. Signup and view all the answers

Define sanity testing.

Sanity testing is a subset of regression testing performed after receiving a software build to ensure that the code changes introduced are working as expected, acting as a checkpoint before further testing. Signup and view all the answers

Explain what White Box Testing involves.

White Box Testing is a technique where software’s internal structure, design, and coding are tested to verify input-output flow and improve design, usability, and security. Testers can see the code, making it transparent and sometimes referred to as Clear box testing or Glass box testing. Signup and view all the answers

What is Regression Testing?

Regression Testing is a type of software testing that confirms recent program or code changes have not adversely affected existing features. It involves re-executing test cases to ensure existing functionalities work fine. Signup and view all the answers

Explain Penetration Testing.

Penetration Testing is an authorized simulated attack on a computer system to evaluate its security. Penetration testers use the same tools, techniques, and processes as attackers to find and demonstrate the business impacts of weaknesses in a system. Signup and view all the answers

Study Notes

Functional Testing

Unit testing involves scrutinizing the smallest testable parts of an application, called units, for proper operation.
Smoke testing is a preliminary check of the software after a build and before a release, finding basic and critical issues.
Sanity testing is a subset of regression testing, ensuring that code changes introduced are working as expected.
Black Box Testing is a software testing method that focuses on input and output of software applications, without knowledge of internal code structure.
White Box Testing is a technique that tests software's internal structure, design, and coding to verify input-output flow and improve design, usability, and security.
User Acceptance Testing (UAT) is a phase of software development in which the software is tested in the "real world" by the intended audience or business representative.

Non-Functional Testing

Performance Testing

Performance testing is a software testing process used to test the speed, response time, stability, reliability, scalability, and resource usage of a software application under a particular workload.
The main purpose of performance testing is to identify and eliminate performance bottlenecks in the software application.

Load and Volume Testing

Load testing is the process of putting simulated demand on software to test its behavior under various conditions.
Volume testing is a type of software testing that subjects the software to a huge volume of data to analyze system performance and response time.

Stress and Security Testing

Stress testing is a software testing activity that determines the robustness of software by testing beyond the limits of normal operation.
Security testing is a type of software testing that uncovers vulnerabilities, threats, and risks in a software application and prevents malicious attacks.

Other Testing Types

Installation testing involves testing the installation procedures of a software system to achieve an installed software system that may be used.
Penetration testing (pen test) is an authorized simulated attack performed on a computer system to evaluate its security.
Compatibility testing is an assessment used to ensure a software application is properly working across different browsers, databases, operating systems, mobile devices, networks, and hardware.
