Understanding API versioning
Contract testing is a powerful concept that allows very fast and robust test automation. However, we shouldn't forget that contract tests are still tests. Sometimes tests fail because of bugs in the code, but sometimes they fail due to expected changes in the code. There are times when we need to update an API so that it invalidates the contract that we have laid out in the specification file. In those cases, we need to update the API definition. However, what if there are people who are still relying on the functionality to work in the way that it used to?
One common way to deal with this problem is by versioning the API. In this section, you will learn about API versioning and when it makes sense to use it.
When you define API versions, you can pick which version of the API you are using when you call the endpoints and it will give back responses that match the specified version. But how do you set that up in Postman? Well, you can create a...
