Load Testing

Load Testing is a type of Performance Testing that determines the performance of a system, software product, or software application under real-life-based load conditions. Load testing determines the behavior of the application when multiple users use it at the same time. It is the response of the system measured under varying load conditions.

Performance Testing

• Performance Testing is a subset of Performance Engineering. It is a process of evaluating a system’s behavior under various extreme conditions. The main intent of performance testing is monitoring and improving key performance indicators such as response time, throughput, memory, CPU utilization, and more.
• There are three objectives (three S) of Performance testing to observe and evaluate: Speed, Scalability, and Stability.
• Types of Performance Testing, Following are the commonly used performance testing types, but not limited to:
  • Load Testing
  • Stress Testing
  • Spike Testing
  • Endurance Testing
  • Volume Testing
  • Scalability Testing
  • Capacity Testing

Stress Testing

Stress Testing is a type of Performance Testing. The objective of stress testing is to identify the breaking point of application under test under extreme normal load.

e.g. Injecting high volume of requests per second to an API might cause the disruption to its service, or throws HTTP 503 Service Unavailable or cause other consequences.

Security Testing

Security Testing is a type of Software Testing that uncovers vulnerabilities, threats, or risks in a software application and prevents malicious attacks from intruders. The purpose of Security Tests is to identify all possible loopholes and weaknesses of the software system which might result in a loss of information, revenue, repute at the hands of the employees or outsiders of the organization.

Accessibility Testing

Accessibility Testing is defined as a type of Software Testing performed to ensure that the application being tested is usable by people with disabilities like hearing, color blindness, old age, low vision and other disadvantaged groups.
