Types of Software Testing

Types of Testing

• Unit Testing: Testing individual units of code, such as functions or methods, to ensure they work as expected.
• Integration Testing: Testing how different units of code work together to ensure they integrate correctly.
• System Testing: Testing the entire system to ensure it meets the requirements and works as expected.
• Acceptance Testing: Testing to ensure the system meets the acceptance criteria and is ready for deployment.

Testing Techniques

• Black Box Testing: Testing without knowledge of the internal workings of the system, focusing on inputs and outputs.
• White Box Testing: Testing with knowledge of the internal workings of the system, focusing on the code and algorithms.
• Gray Box Testing: Testing with some knowledge of the internal workings of the system, combining black box and white box techniques.

Testing Levels

• Component Testing: Testing individual components or modules of the system.
• Component Integration Testing: Testing how components interact with each other.
• System Integration Testing: Testing how the entire system integrates with external systems.

Test Case Design

• Equivalence Partitioning: Dividing input data into partitions and testing each partition at least once.
• Boundary Value Analysis: Testing the boundaries of input data to ensure the system behaves correctly.
• State Transition Testing: Testing the different states of the system and how it transitions between them.

Testing Tools

• Test Automation Frameworks: Tools such as Selenium, Appium, and TestNG that automate testing.
• Test Management Tools: Tools such as JIRA, TestRail, and PractiTest that manage testing activities and track results.
• Defect Tracking Tools: Tools such as JIRA, Bugzilla, and Trello that track and manage defects.

Agile Testing

• Test-Driven Development (TDD): Writing tests before writing code to ensure the code meets the requirements.
• Behavior-Driven Development (BDD): Writing tests that describe the behavior of the system in a natural language style.
• Continuous Integration (CI): Integrating and testing code changes continuously to ensure the system works as expected.

Types of Testing

• Unit testing focuses on individual units of code, such as functions or methods, to ensure they work as expected.
• Integration testing checks how different units of code work together to ensure they integrate correctly.
• System testing involves testing the entire system to ensure it meets the requirements and works as expected.
• Acceptance testing ensures the system meets the acceptance criteria and is ready for deployment.

Testing Techniques

• Black box testing involves testing without knowledge of the internal workings of the system, focusing on inputs and outputs.
• White box testing involves testing with knowledge of the internal workings of the system, focusing on the code and algorithms.
• Gray box testing combines black box and white box techniques, with some knowledge of the internal workings of the system.
