How to run specific cucumber files or tags now?

[rgeraldporter]

Hi! I'm cutting over our tests from nightwatch-cucumber to nightwatch-api, but can't seem to find how you can possibly run tests for specific tags or feature files via the CLI.

start-server-and-test doesn't support passing arguments at all, so outside of writing a script entry for every single feature file & tag we have, I don't see how to get this to work in the new setup. In nightwatch-cucumber it was very easy to do.

Expected Behavior

assuming you have something like:

"test": "start-server-and-test test:setup http-get://localhost:4444/status test:run",

Running
npm run test -- features/something.feature

or

npm run test -- -t @my-tag

Current Behavior

Error: expect: <start script name> <url> <test script name>

(throws errors from start-server-and-test as it doesn't accept any more arguments, let alone passing them along)

Possible Solution

Not sure. start-server-and-test has an open issue about this.

Context

(see above)

But also, when developing tests its fairly typical to only run the feature files you're actually developing, right now outside of writing a custom script line I don't see how to do it.

Your Environment

Node 10.10.0, MacOS 10.13.6, used example linked from nightwatch-cucumber for updating the deprecated module.

In development I suggest to run test:setup and test:run in separate terminals. With that you can achive tow things.

• No server and webdriver restarts with test reexecution
• You can provide addition command line options for Cucumber using npm run test:run -- -some-options.
• Using Cucumber CLI options you can run specific feature files or using expressions you can run specific tags

As I have time will describe this somewhere in the migration docs.

@mucsi96 , is there a way we could pass the environment as well through CLI options instead of passing it in server.js and setup.js files of cucumber examples?

Hi @rgeraldporter here is a link which might help you.

https://github.com/cucumber/cucumber-js/blob/master/docs/cli.md#running-specific-features

https://docs.cucumber.io/cucumber/api/#tag-expressions

Closing this for now.

Hi @spnraju

With nightwatch api i am not able to run a specific feature file, i have also tried the cucumber CLI option but i am not able to run using nightwatch-api
I tried cucumber-setup.js features/google.feature command

[spnraju]

It should be cucumber-js features/google-search.feature.

[mucsi96]

I will add this to cucumber docs

Documentation is updated with filtering feature files and tags

From running with the "--help" flag I can see there is a "--tags" option, but it doesn't work with using @SomeTag, or pointing to a feature file location. Should the flag be removed? I @spnraju 's answer worked for me, but it wasn't apparent.
