Difference between Agile Testing and Waterfall Testing

Agile Testing:
Agile Testing is a type of software testing that involves all members of the project team, special experts and testers. In agile testing, testing is not a different phase and testing is performed along with development phases that includes requirements, design, coding and generation of test cases.Agile testing takes place alongside the Software Development Life Cycle (SDLC). 

Waterfall Testing:
Waterfall Testing is a type of software testing in which testing is a different phase and there are steps and steps classified and testing is performed only in that order. Only after the completion of the one phase or one level next level testing is carried out. 

Difference between Agile Testing and Waterfall Testing:

Agile Testing	Waterfall Testing
In agile testing, testing is not a separate phase.	In waterfall testing, testing is a separate phase.
In agile testing, testing is performed alongside the development.	In waterfall testing, testing is carried out only after the completion of development.
In agile testing, development team and testing team work together.	In waterfall testing, development team and testing team work separately.
In agile testing, testers are involved in the requirements.	In waterfall testing, testers may or may not be involve in the requirements..
In agile testing, acceptance testing is carried out after every iteration.	In waterfall testing, acceptance testing is carried out only in the end.
In agile testing, regression testing is carried out after every iteration.	In waterfall testing, regression testing is carried out only in the end.
In agile testing, there is no time delays between coding and testing.	In waterfall testing, there is normal time delays between coding and testing.
In agile testing, different testing levels overlap.	In waterfall testing, testing levels can’t overlap.
Agile testing methodologies are more flexible.	Waterfall testing methodologies are very rigid compared to agile testing.
In agile testing, the test plan is reviewed after each cycle/sprint.	In waterfall testing,  the test plan is not discussed during a cycle.
