Software Testing

Regression Testing 

Is a type of software testing which verifies that software which was previously developed and tested still performs the same way after it was changed or interfaced with other software. Changes may include software enhancements, patches, configuration changes.

Regression testing is the process of testing changes to computer programs to make sure that the older programming still works with the new changes. Regression testing is a normal part of the program development process and, in larger companies, is done by code testing specialists.

Integration testing 
(sometimes called integration and testing, abbreviated I&T) is the phase in software testing in which individual software modules are combined and tested as a group. It occurs after unit testing and before validation testing

Software Types of testing

• Unit Testing
• Integration Testing
• Functional Testing
• System Testing
• Stress Testing
• Performance Testing
• Usability Testing
• Acceptance Testing
• Regression Testing
• Beta Testing  

Agile 
Software development refers to a group of software development methodologies based on iterative development, where requirements and solutions evolve through collaboration between self-organizing cross-functional teams.

Waterfall 
Model is a linear sequential (non-iterative) design approach for software development, in which progress flows in one direction downwards (like a waterfall) through the phases of conception, initiation, analysis, design, construction, testing, deployment and maintenance

Software Test Plan 
Is a document describing the testing scope and activities. It is the basis for formally testing anysoftware/product in a project. ISTQB Definition. test plan: A document describing the scope, approach, resources and schedule of intended test activities

test cases

Test case 
Is a set of conditions or variables under which a tester will determine whether a system under test satisfies requirements or works correctly. The process of developing test cases can also help find problems in the requirements or design of an application.

black/white box testing

Black box testing 
Is the Software testing method which is used to test the software without knowing the internal structure of code or program. 

White box testing 
Is the software testing method in which internal structure is being known to tester who is going to test the software
