Integration Testing Outline

How to Do Integration Testing?

The Integration Testing Procedure

There is a simple algorithm a QA team can apply to run integration tests: 

• Write a test plan.
• Create test cases and use cases.
• Run tests after unit integration.
• Detect errors.
• Retest the functionality after bug fixing. 
• Repeat the testing cycle until all bugs are fixed.

So, testers should: 

• Understand product structure and be aware of how units interact.
• Be familiar with project peculiarities to be able to write good test cases, analyze the results correctly, and choosing between manual and automated testing.

Integration Test Plans

It includes the following attributes:

• Methods/Approaches to testing (as discussed above).
• Scopes and Out of Scopes Items of Integration Testing.
• Roles and Responsibilities.
• Pre-requisites for Integration testing.
• Testing environment.
• Risk and Mitigation Plans.

Entry Criteria of Integration Testing

• Unit Tested Components/Modules
• All High prioritized bugs fixed and closed
• All Modules to be code completed and integrated successfully.
• Integration tests Plan, test case, scenarios to be signed off and documented.
• Required Test Environment to be set up for Integration testing

Exit Criteria of Integration Testing

• Successful Testing of Integrated Application.
• Executed Test Cases are documented.
• All High prioritized bugs fixed and closed.
• Technical documents to be submitted followed by release Notes.
