Description

When creating AI Tests in a Requirement project (without issue type Test), the Generate Test Cases feature throws an error in the Create Test Cases phase.

Pre-conditions

• Create a project with only Requirements. Be sure the issuetype Test is not there.
• Configure those issue types under Xray Settings >> Test Coverage.

How to reproduce

1. Go to a coverable issue in a Jira project that does not contain the Test issue type.
2. Go to the Test Coverage section.
3. Press the Test Cases Beta button.
4. Select a test type. (Problem is reproducible for both Manual and Gherkin.)
5. Leave Link Preconditions empty.
6. Leave Link Coverage issues prepopulated with the context issue.
7. Enter instructions into "Please share your test requirements".
8. Press Generate Test Cases. The AI will successfully generate test case ideas/topics.
9. Press Review & Edit. The AI will successfully generate a test case with steps for the selected idea.
10. Press Create Tests.

Error loading results
We were unable to generate tests at this time. Please try again later.

For client, it just spins and nothing happens.

Expected result (updated Oct 2, 2025)

• For entry points from the User Story and Precondition issue types where the project does not have the issue type "Test," the entry point button is disabled with the following tooltip: "Project [project key] does not support Test issue types. Enter the test case generation feature from a project with tests, and link this issue if desired."
• For the entry point on the test repository where the project does not have the issue type "Test," the entry point button is disabled with the following tooltip: "Project [project key] does not support Test issue types. Enter the test case generation feature from a project with tests."
