Cucumber 2.0.0 introduces a new way of running specifications. Instead of relying on testthat or devtools test commands to run the tests, cucumber now owns the test execution process.

Follow the steps below to migrate your cucumber tests to the new version.

1. Remove test-cucumber.R file.

In the previous versions, you had to create a test-cucumber.R file with cucumber::test() call to run the tests.

Now, you can run the tests directly from the console or from the R script using the same cucumber::test() function. It now has a new interface and behavior that very similar to devtools::test and testthat::test_package as it now also calls testthat::test_dir internally.

2. Move steps definitions to setup-*.R files.

cucumber::test() no longer is responsible for loading step definitions.

Instead it is recommended to store step definitions in setup-*.R files in tests directory, alongside .feature files.

Convert your directory structure from:

tests/
├── acceptance/
│   ├── steps/
│   │   ├── steps1.R
│   │   ├── steps2.R
│   ├── feature1.feature
│   ├── feature2.feature

to

tests/
├── acceptance/
│   ├── feature1.feature
│   ├── feature2.feature
│   ├── setup-steps1.R
│   ├── setup-steps2.R

All test-*.R files that are in the directory will be ignored by cucumber::test(). To run them use another call to testthat::test_dir().
