Challenges 

The main challenge for our partners at BVG before the start of the project lies in the area of interfaces. External coding presents the BVG team with time and technical challenges in terms of quality assurance.

There was a lack of resources, setup and OpenAPI documentation to check the security and functionality of the complex system.

Result

 

Consistent & precise results through automation

 

Preventing operational blindness through an objective perspective

 

Flexibility through scalable & professional resources

 

Strategy and 
measures

The project consisted of three phases:

1. Analysis

In a joint validation phase, our Appmatics development team asked crucial questions and collected the necessary data.

2. Test planning and implementation

Parallel to the analysis, work began on an automated interface test. Given the large number of endpoints, the development time for the test case was around two weeks so that the API tests could start quickly.

3. Reporting and individual solution

A particular challenge in the case of BVG was the automation of the test procedure with regard to the complex payment system. The Appmatics team developed a technical solution specifically for this purpose.

 

 

Conclusion

Our agile QA solutions enable us to transfer BVG's requirements into the test processes. Together we have achieved the goal:
