What is the command to run a specific feature file in cypress dashboard?

When you say “feature file”, do you mean spec file? i.e. the file with your it() blocks?

yes spec file but i am using cucumber which has step definition and feature file

in cypress.json file -  "testFiles": "**/*.feature" we can specify for all feature files

but if i want to run 2 feature files then what should be the command in cypress. json file?

i have 3 feature file right now. out of them i just want to run only 2 in dashboard

That should be a glob, so I think you can make it a comma separated list, and override that cypress.json property on the command line. There’s docs for them

Just google it, it’s like cypress docs  command line
