Testing Methods

1. White Box Testing

• White box testing is the detailed investigation of internal logic and structure of the code.
• Also called glass testing or open box testing.
• The tester needs to have a look inside the source code and find out which unit/chunk of the code is behaving inappropriately

2. Grey Box Testing

• Its a technique to test the application with limited knowledge of the internal workings of an application.
• "The more you know the better” carries a lot of weight when testing an application.

3. Black Box Testing

• A tester will interact with the system’s user interface by providing inputs and examining outputs without knowing how and where the
  inputs are worked upon.
• Focuses on functional requirement of the software.

4. Functional and Non functional Testing

• Functional testing is a type of software testing in which the system is tested against the functional requirements and specifications.
• Functional testing ensures that the requirements or specifications are properly satisfied by the application.

Examples
• Unit Testing
• Smoke Testing
• Integration Testing
• Regression Testing

5. Non Functional Testing

• Non-functional testing is defined as a type of software testing to check non-functional aspects of a software application. It is designed to
  test the readiness of a system as per non functional parameters.

Examples
• Performance Testing
• Load Testing
• Stress Testing
