Running cucumberjs directly from a node

[Sam Hatoum]

Hi

I'm trying to build a cucumber plugin for a Velocity (the Meteor test runner) and I would like to run individual tests directly from node. My goals are to:

1. Run any one feature or group of features at a time
2. Collect the results into a custom report

Can anyone tell me how to do this please?

My attempts so far are below.

If I run this from the command line:

cd node_modules/cucumber/bin

./cucumber.js /Users/sam/WebstormProjects/meteor-testing/velocity-example/tests/cucumber/features

It works and I get:

1 scenario (1 undefined)

3 steps (3 undefined)

However when I try to do this programmatically like this:

var Cucumber = Npm.require('cucumber');

var featuresDir = '/Users/sam/WebstormProjects/meteor-testing/velocity-example/tests/cucumber/features';

var configuration = Cucumber.Cli.Configuration([featuresDir]);

var runtime   = Cucumber.Runtime(configuration);

var formatter = configuration.getFormatter();

runtime.attachListener(formatter);

runtime.start(function() {

  console.log('runtime.start callback');

});

Cucumber cannot find the suite and the get the following error:

Error: ENOENT, no such file or directory '/Users/sam/WebstormProjects/meteor-testing/velocity-example/.meteor/local/build/programs/server/features'

Which tells me the featuresDir above is being completely ignored.

also tried to take the content of cucumber.js directly and pretend to pass in process.argv like so:

var Cucumber = Npm.require('cucumber');

process.argv = ['/Users/sam/WebstormProjects/meteor-testing/velocity-example/tests/cucumber/features'];

var cli = Cucumber.Cli(process.argv);

cli.run(function (succeeded) {

  var code = succeeded ? 0 : 1;

  process.on('exit', function () {

    process.exit(code);

  });

  var timeoutId = setTimeout(function () {

    console.error('Cucumber process timed out after waiting 60 seconds for the node.js event loop to empty.  There may be a resource leak.  Have all resources like database connections and network connections been closed properly?');

    process.exit(code);

  }, 60 * 1000);

  if (timeoutId.unref) {

    timeoutId.unref();

  }

  else {

    clearTimeout(timeoutId);

  }

});

and got the same error again.

Any one got any ideas?

Hi Sam,

I haven't looked into this myself, but you may want to take a look at how the cucumber-grunt-js plugin is doing the exec:
