You can manually add custom fields on qTest Explorer and map them to the corresponding fields in JIRA.
Click the Add Custom Field link on the Fields Settings form. The Add Custom Field form will be displayed.
Enter Field Name. The Field Name must match the corresponding Field Name in JIRA.
qTest Explorer automatically looks up and populates the Field ID based on the Field Name.
Select Field Type and click Save. The newly added custom field will be displayed on the Fields Settings form.
JIRA integration currently supports only two custom field types: text and date. You may want to make other custom field types optional in JIRA so that a defect from qTest Explorer can be submitted to JIRA successfully.
You can edit or delete custom fields that are created on qTest Explorer.
