Bạn chờ vài ngày nha, mình đang tìm đáp án.

Tất cả các câu hỏi của từng chương là do mình lựa ra từ những đề thi mẫu, những istqb exam cũ, và phải search lại đáp án của chúng trong số tài liệu đó, nên hơi mất thời gian. Khi nào xong mình up lên ngay.

Sorry vì đã trả lời muộn, bị bỏ sót.

1. Integration testing in the small Là kiểm thử mức tích hợp ở phạm vi nhỏ như tích hợp các component với nhau.
2. CAST: Computer-Aided Software Testing - là các công cụ, phần mềm dùng trong quá trình kiểm thử phần mềm, giúp cho việc quản lý và thực hiện các hoạt động test hiệu quả (ví dụ: excel, redmine, jira, bugzilla,...)
