Functional Testing Corporate Training Course

1. Understanding the basics of functional testing
   • Definition of functional testing
   • Objectives and goals of functional testing
   • Role of functional testing in software development

1. Benefits of incorporating functional testing in software development
   • Improved software quality and reliability
   • Enhanced user experience and satisfaction
   • Early defect identification and mitigation
   • Reduced business risks and costs

1. Understanding the functional testing workflow
   • Test planning and strategy development
   • Test case design and execution
   • Defect tracking and reporting
   • Regression testing and retesting

1. Unit Testing:

• Focuses on testing individual components or units of code in isolation.
• Typically performed by developers using frameworks like JUnit or NUnit.
• Helps ensure that each unit functions correctly and meets the expected behavior.

2. Sanity Testing:

• Performed to assess the system's stability quickly after major changes or additions.
• Verifies that the system's most critical functionalities work as expected.
• A subset of regression testing focuses on essential features rather than comprehensive coverage.

3. Smoke Testing:

• A basic level of testing ensures that an application's critical functionalities work.
• Conducted to check if the build or application is stable enough for further testing.
• Helps identify critical failures early in the development lifecycle.

4. Regression Testing:

• Performed to ensure that changes or enhancements to the system do not introduce new defects.
• Re-tests existing functionalities to ensure they still work correctly after modifications.
• Helps maintain the integrity of the system and prevent regression issues.

5. Integration Testing:

• Tests the interaction between multiple components or modules of an application.
• Ensures that integrated components work together as expected.
• Identifies issues related to data exchange, communication, or integration points.

6. Beta/Usability Testing:

• Conducted by real users or a selected group of users before the official release.
• Focuses on gathering feedback about the application's usability, user experience, and acceptance.
• Helps identify usability issues and improve user satisfaction.

7. System Testing:

• Validates the entire system or software application as a whole.
• Tests the system against its functional requirements and specifications.
• Covers end-to-end scenarios and verifies the system's behavior in different environments.

8. End-to-end Testing:

‍‍
• Tests the entire flow of a user's journey through the system.
• Checks if all integrated components and subsystems work together smoothly.
• Verifies the system's functionality, data integrity, and user experience.
  

1. Entry Criteria:

• Prerequisites that must be fulfilled before starting the operational testing phase.
• Examples include completion of unit testing, availability of test environments, and test data preparation.
• Ensures that the system is ready for testing and minimizes potential roadblocks.

2. Exit Criteria:

• Conditions must be met for the completion of functional testing.
• Includes reaching a certain level of test coverage, resolving critical defects, and obtaining stakeholder approval.
• Determines when to stop the testing phase and proceed to the next stage of the software development lifecycle.

1. Positive Testing:

• Validates that the system behaves as expected when given valid inputs.
• Tests the functionality to produce the correct output or response under normal circumstances.
• Focuses on verifying expected behavior and desired outcomes.

2. Negative Testing:

• Verifies how the system handles invalid or unexpected inputs and error conditions.
• Tests error handling, boundary cases, and exception scenarios.
• Aims to identify vulnerabilities, weaknesses, and potential failure points.

1. End-user Based Testing:

• Simulates real-life scenarios and user interactions with the system.
• Tests the system's functionality from an end-user perspective.
• Helps ensure that the application meets user requirements and expectations.

2. Equivalence Tests:

• Divides input data into equivalence classes to minimize redundant test cases.
• Selects representative test cases from each equivalence class for testing.
• Reduces the number of test cases while maintaining sufficient coverage.

3. Boundary Value Tests:

• Focuses on testing the boundaries of input and output ranges.
• Checks the system's behavior at valid and invalid values' lower and upper limits.
• Helps identify issues related to boundary conditions and boundary-related errors.

4. Decision-based Tests:

• Designs test cases based on the system's decision logic or business rules.
• Ensures that all possible decisions and branches are tested.
• Covers different decision outcomes and verifies the correct execution of rules.

5. Alternate Flow Tests:

• Tests alternative paths or scenarios that deviate from the normal flow.
• Focuses on less frequent or exceptional user actions or system behaviors.
• Helps uncover issues in complex or non-linear application flows.

6. Ad-hoc Tests:

• Informal and unplanned testing approaches are based on the tester's intuition and experience.
• Performed without specific test cases or predefined scripts.
• Aims to explore the system, discover defects, and gain insights.
  

1. Functional Testing:

• Focuses on verifying the system's behavior and functionality against requirements.
• Tests if the system does what it is intended to do.
• Involves validating inputs, outputs, user interactions, and expected outcomes.

2. Non-functional Testing:

• Tests aspects of the system beyond functionality, focusing on quality attributes.
• Evaluates performance, reliability, security, usability, and other non-functional aspects.
• Verifies if the system meets specific criteria related to its performance and behavior.
