Integration Testing

What is Integration Testing?

• Is a type of test executed before Unit Test.

• Is a type of test in which only one module or function is tested.

• Is a type of test in which two or more than two functions or modules are tested in an integrated way.

Approaches to perform the Integration Tests

• Big Bang, Functional, Unit

• Bottom Up, System, Functional

• Big Bang, Bottom Up, Top Down, Sandwich Hybrid

• Sandwich Hybrid, Unit, Acceptance

Difference between Unit Test and Integration Test

• Unit Test and Integration Test, can be executed simultaneously

• In Unit Test, one module or function is tested. While in Integration Test, two or more modules are tested in an integrated way.

• In Integration Test, we don't care about the communication within each modules

• There is no difference between Unit Test and Integration Test

Benefits of Integration Testing (Select at least three benefits)

• We can find defects at early, before the code is developed.

• Ensures that the modules are communicated properly.

• Ensures that the modules work in an integrated way.

• Can detect errors related to the interface.

• Bottom Up

• Big Bang

• Top Down
