There are mainly 2 types of incremental testing.

1.top down

2.bottam up

Bottam up begins tesing form the bottom of the hirarchy and works up to the top.moduls are added in the decending hirerichal order.

Bottam up testing requires the devlopment of the driver module which provides the test input,call the module or program being tested display test output.

Bottam up is more advantagaus became it is easy to creat driver rather creating a stub and can serve multiple purposes.output is easier to to examine as it comes from the module directly bove the module under test

Bottom Up Testing: An approach to integration testing where the lowest level components are tested first, then used to facilitate the testing of higher level components. The process is repeated until the component at the top of the hierarchy is tested

Bottam up testing is an approach to integration testing.Here the modules at the lowest level are tested first ,going up in the hierarchy in higher levels.Drivers need to be developed for higher component.

Bottom up testing is one of the approach followed in the Incremental Testing.

Testing the application using this approach is carried out by starting the testing from the lower modules and incrementing towards the top. The lower level modules are tested first and then integrated with the succeeding modules from the bottom of the hierarchy and reaching towards the top.

When main module under construction to check the interface between the sub module, developers use temporary programme called driver, which gives connectivity the main module instead of all modules.
