If there are 1000 features files in Cucumber feature file and I want to execute only even feature fi-CodePudding

1000 feature files in src/test/resources. I want to run only the features file which are even( 2, 4, 6,......1000) how can we do that?

I tried to group them but not sure like this will be good approach.

In Cucumber, you can use tags to specify which feature files or scenarios should be executed. To run only the even feature files in your project, you can add a tag to each of those files and then use that tag to filter which files should be executed.

For example, let's say you have added a tag called @even to each of the even feature files. You can then use the @even tag in your Cucumber command to run only those files, like this:

cucumber -t @even

This will run all of the feature files that have the @even tag, and skip any files that do not have that tag.

Alternatively, you can use the --tags option in your Cucumber command to specify a regular expression that matches the tag names of the feature files you want to run. For example, to run all feature files with a tag that ends in an even number, you could use a regular expression like this:

cucumber -t /@\d*[02468]$/

This regular expression will match any tag that ends in a digit that is an even number (0, 2, 4, 6, or 8).

Overall, using tags and regular expressions in your Cucumber commands can be a powerful way to control which feature files and scenarios are executed and can help you run only the tests that are relevant to your current needs.

If you are using JUnit 5 with Cucumber the you can use a PostDiscoveryFilter from the JUnit Platform to filter out tests.

Something like:

public FilterResult apply(TestDescriptor t) {
   
   // Determine if test descriptor is a feature file based on t.getSource()

   Collection siblings = t.getParent().getChildren();

   // Find index of t in siblings
   // decide to keep or not if index is even


}
