SAP CDS Unit Test — Test Double Framework

Khi nao dung

✅ CDS view co logic dang test duoc (join/association/aggregation/case) can mock data nguon.
✅ RAP BO can test khong dam vao persistence that (dung EML qua test double).
❌ Test method/class ABAP thuong (validate/action helper) — dung sap-unit-test.

3 loai Test Double — chon dung loai

Can mock	Class	Dung khi
CDS view / CDS table entity	`CL_CDS_TEST_ENVIRONMENT`	Test CDS view co logic (join, agg, case)
ABAP SQL tren table/CDS entity	`CL_OSQL_TEST_ENVIRONMENT`	Test class doc qua `SELECT` (khong phai CDS view logic)
RAP BO qua EML (transactional buffer)	`CL_BOTD_TXBUFDBL_BO_TEST_ENV` / `CL_BOTD_MOCKEMLAPI_BO_TEST_ENV`	Test action/determination goi EML toi BO khac

Luu y quan trong (nguon: SAP Help Portal + SAP Community, xem Tham khao):

Phai co key field hop le trong test data — thieu key co the lam framework raise exception.
Khuyen nghi disable DCL khi test (tranh test flaky vi authorization that ap dung) — tim tham so tuong duong (kieu DISABLE_DCL) trong signature create cua ban ABAP dang dung, co the khac ten/vi tri theo version — kiem tra F1/ADT truoc khi dung.
i_dependency_list phai liet ke MOI table/CDS view ma view dang test SELECT tu — thieu 1 cai se khong mock duoc field do, van dam vao data that trong bang goc.

Buoc 2: (Neu can) Mock RAP BO qua EML

Dung CL_BOTD_MOCKEMLAPI_BO_TEST_ENV / CL_BOTD_TXBUFDBL_BO_TEST_ENV khi 1 action/determination trong BO dang test goi EML (MODIFY ENTITIES) toi BO KHAC — tranh test that dam vao persistence cua BO kia.

⚠️ [Unverified — chua tim duoc vi du code chi tiet cho 2 class nay luc soan skill nay, chi xac nhan ten class ton tai va dung muc dich qua tim kiem] Tra cuu truc tiep help.sap.com hoac F1 trong ADT de lay cu phap chinh xac truoc khi dung — KHONG dung code mau vi khong co san o day.

Luu y

⚠️ Test double khong thay the integration test that qua Fiori Elements/OData truoc khi dong ticket (van can quy trinh sap-finish-ticket).
🔗 Test method/class thuong (khong phai CDS/EML) → sap-unit-test.
🔗 Sau khi sinh test: sap-atc-review de check test coverage.
