Compatibility Tests

Image
  What are compatibility tests and how are they performed? Compatibility testing is a type of software testing that evaluates how well a software application performs across different devices, browsers, operating systems, networks, and hardware configurations. The goal of compatibility testing is to ensure that the application functions correctly and consistently across various platforms, environments, and user scenarios. Here's how compatibility testing is performed: Identify Target Platforms: Determine the target platforms, environments, and configurations on which the software application needs to be tested. This may include different operating systems (e.g., Windows, macOS, Linux), web browsers (e.g., Chrome, Firefox, Safari, Edge), mobile devices (e.g., iOS, Android), screen resolutions, and network conditions. Create Test Environment: Set up a test environment that replicates the target platforms and configurations identified in the previous step. This may involve using virtu...

Unit Testing

Image
  What is Unit testing: Unit testing is a software testing technique in which individual units or components of a software application are tested in isolation to ensure that they function correctly. A unit typically refers to the smallest testable part of the software, such as a function, method, or class. The primary goal of unit testing is to validate that each unit behaves as expected, performs its intended functionality, and produces the correct output for a given input. Key characteristics of unit testing include: Isolation: Unit tests are designed to isolate the unit being tested from external dependencies, such as other modules, components, or external systems. This ensures that the test focuses solely on the behavior and logic of the unit under test. Automated: Unit tests are automated, meaning they can be executed automatically without manual intervention. Automated unit tests are typically written using testing frameworks or libraries and can be run frequently during th...

Different Types of Non-Functional tests

Image
  What are the different types of non-functional tests: Non-functional testing focuses on aspects of a software system beyond its specifi c behaviors or features. These tests evaluate how well a system performs under various conditions and its overall quality attributes. Here are some common types of non-functional tests: 1. Performance Testing: Purpose: Performance testing assesses the responsiveness, scalability, reliability, and efficiency of a software application under various workload conditions. Types: Load Testing: Evaluates the system's performance under anticipated load levels. Stress Testing: Tests the system's behavior under extreme load conditions to determine its breaking point. Scalability Testing: Measures the system's ability to handle increased workload by adding resources. Endurance Testing: Validates the system's performance over an extended period to identify any degradation over time. 2. Load Testing: Purpose: Load testing evaluates the system'...

Blackbox and Whitebox Tests

Image
  Difference between blackbox and whitebox tests: Black-box testing and white-box testing are two fundamental approaches to software testing, each with its own methodology and objectives. Here are the key differences between black-box testing and white-box testing: 1. Black-box Testing: Definition: Black-box testing, also known as behavioral testing or functional testing, focuses on testing the software from an external perspective without knowledge of its internal structure or implementation details. Perspective: Testers view the software as a black box, interacting with it solely through its external interfaces (e.g., user interface, APIs) and inputs and observing the outputs or responses. Testing Objective: The primary goal of black-box testing is to validate the software's functionality, usability, and compliance with specified requirements. Test Design: Test cases are designed based on requirements, specifications, or user stories, without considering the internal logic, c...
