How to pass variables between cucumber-jvm steps

by

In order to share commonalities between steps you need to use a World. In Java it is not as clear as in Ruby.

Quoting the creator of Cucumber.

The purpose of a “World” is twofold:

  1. Isolate state between scenarios.

  2. Share data between step definitions and hooks within a scenario.

How this is implemented is language specific. For example, in ruby,
the implicit self variable inside a step definition points to the
current scenario’s World object. This is by default an instance of
Object, but it can be anything you want if you use the World hook.

In Java, you have many (possibly connected) World objects.

The equivalent of the World in Cucumber-Java is all of the objects
with hook or stepdef annotations. In other words, any class with
methods annotated with @Before, @After, @Given and so on will be
instantiated exactly once for each scenario.

This achieves the first goal. To achieve the second goal you have two
approaches:

a) Use a single class for all of your step definitions and hooks

b) Use several classes divided by responsibility [1] and use dependency
injection [2] to connect them to each other.

Option a) quickly breaks down because your step definition code
becomes a mess. That’s why people tend to use b).

The available Dependency Injection modules are:

  • cucumber-picocontainer
  • cucumber-guice
  • cucumber-openejb
  • cucumber-spring
  • cucumber-weld
  • cucumber-needle
