What is Integration Testing?

INTEGRATION TESTING is defined as a form of experimentation wright here software application modules are integrated logically and also tested as a team. A typical software program project consists of multiple software application modules, coded by different programmers. The objective of this level of experimentation is to expose defects in the interaction in between these software program modules as soon as they are integrated


Integration Testing focuses on checking information communication amongst these modules. Hence it is likewise termed as ‘I & T’ (Integration and Testing), ‘String Testing’ and also occasionally ‘Threview Testing’.

How to do Integration Testing?

The Integration test procedure irrespective of the Software experimentation tactics (debated above):

Prepare the Integration Tests PlanDeauthorize the Test Scenarios, Cases, and Scripts.Executing the test Cases adhered to by reporting the defects.Tracking & re-experimentation the defects.Steps 3 and 4 are repetitive till the completion of Integration is effective.

Quick Description of Integration Test Plans:

It consists of the adhering to attributes:

Methods/Approaches to experimentation (as disputed above).Scopes and Out of Scopes Items of Integration Testing.Roles and Responsibilities.Pre-requisites for Integration trial and error.Testing atmosphere.Risk and Mitigation Plans.

Entry and Exit Criteria of Integration Testing

Entry and Exit Criteria to Integration experimentation phase in any type of software development model

Enattempt Criteria:

Unit Tested Components/ModulesAll High prioritized bugs resolved and closedAll Modules to be code completed and incorporated properly.Integration tests Plan, test case, scenarios to be signed off and also recorded.

Exit Criteria:

Successful Testing of Combined Application.Executed Test Cases are documentedAll High prioritized bugs fixed and also closedTechnical papers to be submitted adhered to by release Notes.

Best Practices/ Guidelines for Integration Testing

Study the Architecture architecture of the Application and recognize the Critical Modules. These should be tested on priority.Obtain the interchallenge deindications from the Architectural team and also develop test instances to verify all of the interdeals with in detail. Interconfront to database/external hardware/software program application have to be tested in detail.After the test instances, it’s the test data which plays the critical function.Almethods have actually the mock data ready, before executing. Do not choose test data while executing the test situations.
