Demo: using contract testing to bridge the gap between unit and integration tests

  • 1.  Demo: using contract testing to bridge the gap between unit and integration tests

    Posted Tue November 03, 2020 09:04 AM
    I recently did a session on Lets Code which might interest this community. I talk about some of the dos, don't, and whys of application modernisation. In a microservices context, testing has some unique challenges. Unit tests are always important, and there should be a lot of them - but they can't catch integration bugs. Integration tests give great confidence that the whole system works as intended, but they're complex to run. This is where consumer-driven contract tests come in; they test the seams in the application, without the expense of integration tests. As well as validating the relationship between services, a good contract test framework acts as a super-handy mock for testing the consumer, and a 'for free' test suite for service providers. I demo a simple app dev scenario to show how Pact (a contract test framework) can help: https://techtv.bemyapp.com/#/conference/5f7230a8c0311b001bf90329
