A ‘dependency’ is an object that can be used, for example as a service.

What is dependency injection in cucumber?

Cucumber will create a new instance of each of your glue code classes before each scenario. … PicoContainer (The recommended one if your application doesn’t use another DI module)

Is TestNG better than Cucumber?

If your current tests are already using TestNG, then it will be easier to run Cucumber tests with TestNG engine. At the opposite, if you already have JUnit tests, it could be easier to use JUnit for Cucumber run (but TestNG is able to run JUnit tests, so you can use TestNG in that case too).
