Question

Research best practices for system integration approaches, such as the systems development life cycle (SDLC) approach, migration strategy and implementation approach, acquisition utilizing requests for proposals, and many others. Select 2 of the best practice approaches, and discuss how they support responding to professional and ethical issues that could potentially impact your integration project. Provide specific examples of how the application of best practices for system integration impact project success.

Explanation / Answer

After Reading the given problem statement for the SDLC life cycle of Integration of project. I have stated the five best practices approches for Integration of Project..See these below..

Integration testing is a critical phase in the software development process in which individual units are combined and tested collectively, with a focus on the interfaces between applications. This typically occurs after unit testing has been completed and before system testing, providing a bridge between software functionality and full system operation.

Five integration testing “best practices” are critical to any successful software project:

1. Assemble a Test-Plan Document

Before embarking on an integration testing process, it’s important to create a plan and have a common document for the entire team to reference. Doing so will help the test team map out a logical sequence for the test process. In addition, this methodology will provide the means to document the process on an individual level while maintaining consistency with the rest of the team’s efforts.

Additionally, this document will provide project managers with everything they need to know about the process, allowing them to allocate resources (lab equipment, time in lab, etc.) accordingly.

2. Complete Unit Testing Prior to Integration Testing

The integration testing strategy cannot be successfully executed if code has not first passed the unit testing step. Unit tests are written by developers to ensure a small piece of code is functioning properly. They shouldn’t have any dependencies on outside systems, rather, they should test internal consistency.

Using unit testing to check code before passing it further down the funnel will reduce the amount of bugs testers and users experience as they start to test individual pieces and how small collections work together(integration testing). Integration tests validate that functional sub processes within the system work appropriately when put together, and without unit testing, buggy code could be present before integration even takes shape.

3. Use a Team Approach to Testing

It’s hard work to engineer clean, bug-free code. Sharing information across the team helps make the test process go more smoothly, as everyone is on the same page. Software quality and release dates can slip if information about the integration test activities is not shared across the entire development team. A siloed, throw-it-over-the-wall type of approach will most likely result in costly delays between when the code is written and bugs are found, making it very difficult to fix the bugs in a timely manner.

Successful testing means that software quality is everyone’s job, and requires a team approach.

4. Have a Software Test Management System in Place

Application source code is always being modified (often times by a number of different developers) and as these new features are added and bug fixes are integrated, unexpected consequences can arise.

Keeping this in mind, integration tests should leverage a test collaboration platform that provides a single point-of-control for test activities, dashboards, and pass/fail reports. Utilizing a system with these attributes will give each member of the team a real-time view of current testing status’ and release preparedness. The data it presents users will allow them to compare current status to historical results and use analysis to identify trends over time.

5. Automate Testing When Possible

Integration testing should be as automated as possible without compromising the integrity of the process. Manually checking for defects is tedious, time-consuming, and in some cases, ineffective. Automated integration testing allows development teams to continue working forward as the software is being tested. Additionally, automation runs tests repeatedly and quickly, increasing the chances that small defects will be identified immediately, giving developers time to make appropriate fixes.

Having an effective integration testing strategy in place is crucial to the software development process. Hopefully, these five tips provide some value to those looking to begin integration testing their designs, on their way to building innovative embedded software.
