One of the things to do is to package your application up inside a Docker Image where you have the required Operating System (OS) and the Runtime libraries (JVM) for running your Java app baked in. With Spring Boot, you can build an executable runnable jar where you can run on any server that has the JVM installed.īut there is one last step i feel that is required and that is to make your app releasable or more specifically: deployable. So here’s some examples of adding the dependencies to the Maven pom file:īy this point you have basically setup most of the things you require for your Java project. Just like for Unit Testing where you include the JUnit library, with E2E testing where you use Cucumber-JVM you would just include the Cucumber-JVM dependency too.

Note that there are many other ports for other programming languages too. But since my project is Java, i use the Java port of Cucumber - namely Cucumber-JVM. I won’t go into BDD too much but put simply, BDD aims to solve the problems TDD gave and BDD acts as a broader and more next level approach to a Test First approach where it aims at writing E2E Tests as Acceptance Criteria combining with writing those test specifications in a human readable English like language (that even a Business Analyst - BA can write) - a.k.a Gherkin in the Cucumber world.Ĭucumber originated from Ruby. Ĭucumber is a Behaviour Driven Design (BDD) Testing Tool. The framework i commonly use is Cucumber 🥒. And as you have just seen, Integration Testing can be really messy to setup depending on what tools, technology, software libraries, frameworks you decide to use.įor me, i like to categorize E2E Tests specifically as i mainly like to separate specific E2E Tests from more broader generic Integration Tests (the tests that sit in the middle of the traditional Testing Pyramid). After all, E2E is a subset of the broader Integration Testing described above. It also depends on how you plan to do it. This step can vary depending on what kind of tools you decide to use for doing ‘End 2 End’ (E2E) testing.
