Integration testing

Reducing risk around the interface between software components.

The challenge

Integrating new software into legacy systems or interfacing new modules coded in isolation by different teams is a pivotal moment in the development process. It’s vital to step back and look at the bigger picture, so that any issues arising as the different components operate in combination are identified as early as possible.

Making integration testing part of the testing cycle and planning sufficient test coverage will verify whether or not two or more modules interact correctly, as expected, to support the full end-to-end operation of a system.

Our expertise

Digivante has years of experience of working with clients to expose issues with the interaction between integrated units, whether these include different databases, separate platforms, new modules, legacy systems or other software components.

In being able to mobilise our global testing community to identify significant issues and isolate the failures at an early stage, we quickly assess how coupled software systems interact, so any anomalies can be promptly rectified.

This is a much more cost-efficient route to remediation than waiting until the user acceptance phase or, even worse, the go-live.

Digivante’s services for integration testing

We can advise on which of the following services will support fast, efficient integration testing for your business by applying best practice:

  • Regression testing – support to release new functionality and features at speed.

  • Test planning – getting testing right, right from the start.

  • Writing test cases – best practice applied throughout this essential phase in the QA lifecycle.

  • Test case execution – professional testing services to support your innovation strategy.

Real client use case

Our client’s CMS is used to quickly update content which then appears immediately on their front-end website. Fields and formats within the system are regularly updated, added, and hierarchies changed, meaning we need to ensure they are working with existing content as well as working with the new functionality. We use Swagger UI (the integration test tool) to allow us to post, set and get data between the backend database system and the content management system. This ensures that the content team are not impacted by functional issues and can continue to update the website quickly and with confidence.

Digivante helps to reduce risk when integrating different software components by delivering:

• Validation that multiple modules work together as intended and designed

• Detection of issues related to the interface between modules to support fast mitigation

• Extensive system-wide coverage, as opposed to unit and system testing that are specific to individual modules.
