Integration Test Plan
The integration test plan is the overall plan for carrying out the activities in the integration test level, which contains the following sections.

What is to be tested?
This section clearly specifies the kinds of interfaces fall under the scope of testing internal, external interfaces, with request and response is to be explained. This need not go deep in terms of technical details but the general approach how the interfaces are triggered is explained.

Sequence of Integration
When there are multiple modules present in an application, the sequence in which they are to be integrated will be specified in this section. In this, the dependencies between the modules play a vital role. If a unit B has to be executed, it may need the data that is fed by unit A and unit X. In this case, the units A and X have to be integrated and then using that data, the unit B has to be tested. This has to be stated to the whole set of units in the program. Given this correctly, the testing activities will lead to the product, slowly building the product, unit by unit and then integrating them.

List of Modules and Interface Functions
There may be N number of units in the application, but the units that are going to communicate with each other, alone are tested in this phase. If the units are designed in such a way that they are mutually independent, then the interfaces do not come into picture. This is almost impossible in any system, as the units have to communicate to other units, in order to get different types of functionalities executed. In this section, we need to list the units and for what purpose it talks to the others need to be mentioned. This will not go into technical aspects, but at a higher level, this has to be explained in plain English.

Apart from the above sections, the following sections are addressed, very specific to integration testing.
•   Integration Testing Tools
•   Priority of Program interfaces
•   Naming convention for test cases
•   Status reporting mechanism
•   Regression test approach
•   ETVX criteria
•   Build/Refresh criteria {When multiple programs or objects are to be linked to arrived at single product, and one unit has some modifications, then it may need to rebuild the entire product and then load it into the integration test environment. When and how often, the product is rebuilt and refreshed is to be mentioned}.

Thank you for this....

 

I'm really learning from this Forum....

Integration Testing:  “Integration testing” is the next level of testing. This ‘level of testing’ focuses on testing the integration of “units of code” or components.

Prerequisites for Integration Testing:

Before we begin Integration Testing it is important that all the components have been successfully unit tested.

Integration Testing Steps:

Integration Testing typically involves the following Steps:
Step 1: Create a Test Plan
Step 2: Create Test Cases and Test Data
Step 3: If applicable create scripts to run test cases
Step 4: Once the components have been integrated execute the test cases
Step 5: Fix the bugs if any and re test the code
Step 6: Repeat the test cycle until the components have been successfully integrated

As we covered in various articles in the Testing series there are various levels of testing:

Unit Testing, Integration Testing, System Testing

Each level of testing builds on the previous level.

“Unit testing” focuses on testing a unit of the code.
“Integration testing” is the next level of testing. This ‘level of testing’ focuses on testing the integration of “units of code” or components.

How does Integration Testing fit into the Software Development Life Cycle?

Even if a software component is successfully unit tested, in an enterprise n-tier distributed application it is of little or no value if the component cannot be successfully integrated with the rest of the application.

Once unit tested components are delivered we then integrate them together.
These “integrated” components are tested to weed out errors and bugs caused due to the integration. This is a very important step in the Software Development Life Cycle.

It is possible that different programmers developed different components.

A lot of bugs emerge during the integration step.

In most cases a dedicated testing team focuses on Integration Testing.
