Python Pytest 是否与 Java TestNG DataProvider 类似？ Pytest 如何处理 Excel 数据？

Question

再次更新了问题和代码以反映最近的更改。 Amit 我尝试了您的建议，但遇到了错误。试图通过传入测试名称让 openpyxl 从工作簿中的每个 excel sheet 读取日期，但它一直失败，找不到测试名称夹具。你能告诉我哪里出错了吗？谢谢。

from openpyxl import load_workbook

class ExcelUtils():

def __init__(self, driver):
    self.driver = driver

def get_input_rows(self, datafile, testName):

    wb = load_workbook(filename=datafile)

    sheet = wb.active

    # List sheets available
    sheets = wb.get_sheet_names()
    for i in sheets:
        if i == testName:
            sheet = i
    self.log.info("Got active sheet.")

    row_list = []

    # Get second row as the headers' values
    rows2 = sheet.iter_rows(min_row=2, max_row=2)
    secondrowvalues = next(rows2)
    for d in secondrowvalues:
        row_list.append(d.value)

    return row_list

Answer 1

您可以创建另一个函数（或夹具），您可以在其中读取 excel 并生成字典元素。然后你可以使用 @pytest.mark.parametrize 到运行对字典中的每个元素进行测试。

这是一个类似的示例，其中函数 returns 来自 excel 的行，然后使用 @pytest.mark.parametrize

对每一行进行测试运行

def get_data():
    data = ExcelUtils("inputData.xlsx", "SheetName").get_input_rows()
    for row in data:
        yield row

@pytest.mark.parametrize("test_input", get_data())
def test_for_all_input_rows(test_input):
    print(test_input)

Does Python Pytest have anything similiar to Java TestNG DataProvider? How does Pytest Handle Excel Data?
