There are four levels of software testing: Unit >> Integration >> System >> Acceptance.
1.
Unit Testing is a level of the software testing process where individual
units/components of a software/system are tested. The purpose is to validate
that each unit of the software performs as designed.
2.
Integration Testing is a level of the software testing process where individual
units are combined and tested as a group. The purpose of this level of testing
is to expose faults in the interaction between integrated units.
3.
System Testing is a level of the software testing process where a complete,
integrated system/software is tested. The purpose of this test is to evaluate
the system’s compliance with the specified requirements.
4.
Acceptance Testing is a level of the software testing process where a system is
tested for acceptability. The purpose of this test is to evaluate the system’s
compliance with the business requirements and assess whether it is acceptable
for delivery.
