Làm cách nào tôi có thể đọc dữ liệu từ MS Excel?

Provar có các bước kiểm tra Đọc và Viết để đọc dữ liệu từ trang tính Excel hoặc cơ sở dữ liệu và ghi dữ liệu vào bảng tính Excel

Trang này mô tả cách định cấu hình Provar để kiểm tra bằng cách sử dụng dữ liệu từ Excel. Bạn cũng có thể tham khảo Ghi dữ liệu vào Excel để biết thêm thông tin

Để đọc từ trang tính Excel, trước tiên hãy chuẩn bị sẵn tệp Excel trên máy cục bộ của bạn

Ghi chú. Bạn nên lưu tệp trong thư mục mẫu trong không gian làm việc của mình

Tiếp theo, đọc tệp Excel vào trường hợp thử nghiệm của bạn bằng cách sử dụng Thêm nguồn giá trị tham số. Bạn có thể thực hiện việc này từ bất kỳ bước kiểm tra nào, nhưng bạn sẽ thường thấy hữu ích khi thực hiện việc này ở bước kiểm tra Cho từng người, nếu bạn đang sử dụng một bước kiểm tra. (For Each thường được sử dụng trong Kiểm tra theo hướng dữ liệu để lặp lại cùng một hành động qua từng hàng dữ liệu. )

Để đọc dữ liệu Excel vào Trường hợp thử nghiệm của bạn, hãy bấm vào biểu tượng Thêm nguồn giá trị tham số (

Thao tác này sẽ thêm phần mới sau vào Bước kiểm tra của bạn

Bạn có thể điền này như sau

Bước 1. Nếu bạn đang sử dụng máy Windows, hãy chuyển đến tệp Excel của bạn và đánh dấu phạm vi ô mà bạn muốn đọc trong Provar. Sau đó chọn CTRL+C để sao chép. Điều hướng đến Provar và chọn biểu tượng Populate From File (

Bước 2. Nếu đang sử dụng máy Mac, bạn sẽ cần điền Tệp, Bảng tính và Phạm vi giá trị theo cách thủ công. Sử dụng Trình chọn tệp (

Bước 3. Trong trường Tên, hãy chọn hướng của tiêu đề

Bước 4. Trong trường Địa điểm, chỉ định bất kỳ bộ lọc nào bạn muốn áp dụng cho dữ liệu được nhập

Bước 5. Trong Biến, chỉ định tên đối tượng ưa thích của bạn cho kết quả (mặc định là ExcelData)

Bước 6. Sau đó tham số hóa Test Case

Dưới đây là một bảng tính Excel ví dụ với các tham số Nguồn giá trị tham số tương ứng được điền bên dưới

Thêm vào trường hợp thử nghiệm

Khi bạn đã đọc dữ liệu từ trang tính Excel, bạn cần sử dụng nó trong trường hợp thử nghiệm của mình. Điều này thường được thực hiện bằng cách sử dụng bước kiểm tra For Each hoặc While để lặp qua nhiều hàng và tạo bước kiểm tra để tạo dữ liệu

Bước 1. Sử dụng Hỗ trợ nội dung để truy cập các trường trong đối tượng SourceData

Bước 2. Chỉ định tên danh sách (e. g. SourceData) và Tên giá trị trong bước kiểm tra Đối với mỗi. (Tên giá trị là tên cho lần lặp hiện tại. )

Trước đó chúng tôi đã giới thiệu Apache POI- một API Java hữu ích để tương tác với các tài liệu Microsoft Office. Bây giờ chúng ta sẽ xem làm thế nào chúng ta có thể đọc và ghi vào tệp excel bằng API

Thủ tục. Viết tệp bằng POI rất đơn giản và bao gồm các bước sau

1. Tạo sổ làm việc
2. Tạo sheet trong workbook
3. Tạo một hàng trong trang tính
4. Thêm ô trong trang tính
5. Lặp lại bước 3 và 4 để ghi thêm dữ liệu
6. Đóng luồng đầu ra

Đọc một tệp Excel

Thủ tục. Việc đọc một file excel cũng rất đơn giản nếu chúng ta chia thành các bước

1. Tạo phiên bản sổ làm việc từ trang tính excel
2. Đến trang tính mong muốn
3. Tăng số hàng
4. lặp lại trên tất cả các ô trong một hàng
5. lặp lại bước 3 và 4 cho đến khi tất cả dữ liệu được đọc
6. Đóng luồng đầu ra
