I am following BDD approach. So I created the BDD feature (story) and I have created a multiple test for that story but while downloading the feature file am not getting full content. Am getting only the title and description
As per the screenshots I can see that you have created normal test not BDD Scenarios (Test scenarios), so test case data is not showing in feature file
If Test issue type is having label BDD_Scenario then we will consider the test case as BDD Scenario (Gherkin editor will display), if Test doesn't have any label with name BDD_Scenario then it will be normal test cases (Manual test case you can see normal test detail section with default fields as step, data, result)
If BDD story is linked with BDD scenarios then only test detail section will be downloaded in feature file, in your case please add label BDD_Scenario to the linked test cases and retry the download feature file from Story
Yes a BDD scenario is still a Zephyr test. However if you open the test details panel using the Zephyr button provided right under the feature name, you will be able to use gherkin script to add content to your scenario.
