执行和生成报告：

1）在main文件中加入如下代码：

1）在main文件中加入如下代码：
if __name__ == '__main__':
    # 指定临时json文件生成位置    
    pytest.main(["./case/test_visit_url_screenshot.py",                 
                "-sv", "--alluredir", "./report/temp_jsonreport"])
    # 指定html报告生成位置，清理上次生成的报告    
    os.system("allure generate ./report/temp_jsonreport -o ./report/html --clean")

2）生成报告包含两个文件：

先生成temp_jsonreport，再生成html，用浏览器打开index.html即可

@allure.feature()、@allure.story()、@allure.title()、with allure.step 使用

使用举例1***：

1、把基础操作，写成函数放到action.py，方便重复调用

2、在测试用例里写清feature用例模块、story用例场景、title用例名称、用例步骤step，调用action里的函数即可

import logging

    """
    Step1、input one URL
    Step2、generate multi-language URL
    Step3、visit URL, take screenshot
    """
    @allure.story("生成指定多语言URL后访问")
    def test_take_screenshot(self, driver):
        url_list = read_yaml(data_folder, "url.yaml")
        # logging.info("urls list: %s" % url_list)
        language_dict = read_yaml(data_folder, "language.yaml")
        if not language_dict:
            language_dict = default_language_dict
        # logging.info("language dict: %s" % language_dict)

        task_name = read_yaml(data_folder, "other.yaml")["task_name"]
        logging.info("task_name: %s" % task_name)

        urls = gen_multi_language_url(language_dict=language_dict, url_list=url_list)
        folder_path = gene_folder_path(task_name_pa=task_name)

        # 设置访问URL
        for language, urls_list in urls.items():
            logging.info("language: %s", language)

            for each_url in urls_list:
                Action.visit_url(driver=driver, url=each_url)
                time.sleep(5)

                # 生成截图的文件路径
                png_path = gene_screenshot_abs_path(folder_path_pa=folder_path, language_pa=language)
                Action.save_screenshot(driver, png_path)

                # 将截图嵌入报告
                allure.attach(driver.get_screenshot_as_png(), "截图", allure.attachment_type.PNG)

跳过测试 -- @pytest.mark.skip(reason=”hhh”)

# 参数化 ，传入字典数据

json = ({"username": "alex", "password": "123456"}, {"username": "rongrong", "password": "123456"})

@pytest.mark.parametrize("json", json)
@pytest.mark.skip()
def test_para5(self, json):

    print("{json}")  # 语法：{json} 且必须加引号
    print('username: {json["username"]}, password: {json["password"]}') # 语法：{json}

执行结果：

 参数化 -- @pytest.mark.parametrize

# 单个值，运行一次

@allure.story("场景：pytest.mark.parametrize使用")
@allure.title("单个参数，单个值")
@pytest.mark.parametrize("name", ["san"])
def test_para(self, name):

    print(name)

# N个值，运行N次
@allure.title("单个参数，多个值")
@pytest.mark.parametrize("name", ["san", "si", "wu"])
def test_para(self, name):
    print(name)

# N个值，运行N次
@allure.title("多个参数，多个值")
@pytest.mark.parametrize("name, pw", [("san", "123456"), ("si", "123456"), ("wu", "123456")])
def test_para(self, name, pw):
    print("%s %s" %(name, pw))

# 多个参数的混合使用，笛卡儿积

data1 = [1, 2]
data2 = ["wu", "liu"]
data3 = ["biu", "kuang"]

@pytest.mark.parametrize("a", data1)
@pytest.mark.parametrize("b", data2)
@pytest.mark.parametrize("c", data3)
def test_para(self, a, b, c):
    print("new sentence: [{a}, {b}, {c}]")

# 参数化 ，传入字典数据

json = ({"username": "alex", "password": "123456"}, {"username": "rongrong", "password": "123456"})

@pytest.mark.parametrize("json", json)
def test_para(self, json):

    print("{json}")  # 语法：{json} 且必须加引号
    print('username: {json["username"]}, password: {json["password"]}') # 语法：{json}

失败case重复执行 -- pytest-rerunfailures

& @pytest.mark.flaky(reruns=2, reruns_delay=5)

背景：当服务器不稳定，偶尔出现波动、本地网络偶尔出现不稳定等情况，导致用例执行失败，这种情况大家都觉得用例标记失败不太合理，想要在用例执行失败后延时一些时间再次进行执行，如果超过3次仍然失败，则表明用例执行失败；所以就需要失败重跑功能。

前提条件： pytest (>=5.3) 和python >=3.6

安装：pip install pytest-rerunfailures

查看安装版本：pip show pytest-rerunfailures

方式一：加装饰器：

# 参数化 ，传入字典数据

json = ({"username": "alex", "password": "123456"}, {"username": "rongrong", "password": "123456"})

@pytest.mark.parametrize("json", json)
@pytest.mark.flaky(reruns=2, reruns_delay=5)
def test_para5(self, json):

    print("{json}")  # 语法：{json} 且必须加引号
    print('username: {json["username"]}, password: {json["password"]}') # 语法：{json}
    assert 1 == 2

注：失败用例重试2次，每次延时5秒

方式二：命令行执行
在命令行输入： pytest -v --reruns 3 --reruns-delay 5 test_rerun.py失败用例重试3次，每次延时5秒，

命令行会覆盖用例的装饰器
