Bilt Rewards partners with property managers across the US to provide renters a loyalty program for earning points when making rent payments. Renters can use these points to purchase services or transfer them to other loyalty programs.
Accurately simulating system behavior during development and integration tests; parallelizing work between back and front-end teams.
After working with open source WireMock for unit testing, Bilt Rewards adopted WireMock Cloud as a platform to prototype and mock APIs and remove blockers in the development process.
Developers spend more time on development and testing rather than managing the environments
Supporting complex mocking and integration testing use cases using proxies and finite state machines.
Back-end and front-end development teams have a common reference for API specifications.
Bilt Rewards is a loyalty program for renters in the United States. By paying rent, residents earn points which can be used to book travel, fitness classes, apply cash, or transfer points to other loyalty programs such as airlines.
The software is built using a microservices architecture and integrates with a large number of third-party services. Developing and testing against these API integrations was becoming challenging, especially when the APIs weren’t readily available or when more complex scenarios needed to be simulated.
Enabling parallel development and realistic testing
Bilt works with its own microservices and multiple third-party services, many of which do not provide test environments; in services that did provide a sandbox, Bilt still ran into challenges replicating real-life conditions such as negative scenarios. Hence, they had to invest development time to create realistic environments before rolling their app out to production.
They were looking for a tool that would:
run mock APIs in lower environments to understand how they would behave in production;
have the ability to simulate error states; and
help parallelize the work between back-end and front-end development teams.
“We looked at other tools, but none could match the sophistication that WireMock offers.”
“Having a hosted WireMock Cloud experience that has
an easy user interface, access controls, integration with our SSO provider - it was really helpful so that we can just get started using it without having the burden and cost of operating the open source."
WireMock Cloud provides quick time to value and less development work
After looking at other Java-based mocking solutions that offered basic request-response capabilities, Bilt Rewards chose WireMock to mock both third party and internal APIs and accelerate development processes. WireMock offers sophisticated features such as proxying and finite state machines, which enable Bilt Rewards to string together a sequence of calls and branch out in terms of the behavior based on various parameters.
Having used the open-source version of WireMock for unit testing, Bilt Rewards opted for WireMock Cloud to collaborate on API design and run full integration tests in a realistic cloud environment. WireMock Cloud allowed them to easily migrate their mocks and validate that the application continued working when deployed in real-life conditions, and removed much of the additional overhead of managing the environment.
On-time project delivery with fewer developer resources
"Since we were already working with open source WireMock, moving to the cloud-hosted version was just a natural extension
Shorter release cycles, more predictable schedules and fewer defects in production.
