1、数据驱动

参数化数据读取外部文件：使用yaml、json数据
测试步骤读取自外部文件：定制执行引擎
断言步骤读取自外部文件：定制执行引擎
整个用例读取自外部文件：动态构建用例

2、参数化的数据驱动

    @pytest.mark.parametrize("keyword, expected_price", yaml.safe_load(open("search.yaml", "r")))
    def test_001(self, keyword, expected_price):
    def test_001(self, keyword, expected_price):
        self.driver.find_element(AppiumBy.ID, "com.xueqiu.android:id/tv_banner").click()
        self.driver.find_element(AppiumBy.ID, "com.xueqiu.android:id/search_input_text").send_keys(keyword)
        self.driver.find_element(AppiumBy.ID, "name").click()
        price = self.driver.find_element(AppiumBy.ID, "current_price")
        # hamcrest定位：from hamcrest import *
        assert float(price.text) > expected_price
        assert "price" in price.get_attribute("resource-id")
        assert_that(price.get_attribute("package"), equal_to("com.xueqiu.android"))

search.yaml的数据格式

- [ pdd, 20]
- [ alibaba, 100]
- [ jd, 10]

    def test_001(self):
