Allure-pytest功能特性介绍

前言

Allure框架是一个灵活的轻量级多语言测试报告工具,它不仅以web的方式展示了简介的测试结果,而且允许参与开发过程的每个人从日常执行的测试中最大限度的提取有用信息
从dev/qa的角度来看,Allure报告简化了常见缺陷的统计:失败的测试可以分为bug和被中断的测试,还可以配置日志、步骤、fixture、附件、计时、执行历史以及与TMS和BUG管理系统集成,所以,通过以上配置,所有负责的开发人员和测试人员可以尽可能的掌握测试信息。
从管理者的角度来看,Allure提供了一个清晰的“大图”,其中包括已覆盖的特性、缺陷聚集的位置、执行时间轴的外观以及许多其他方便的事情。allure的模块化和可扩展性保证了您总是能够对某些东西进行微调,使Allure更适合您,那么今天我们就来说说如何使报告更加详细的显示我们需要的信息,以及allure与jenkins的集成

生成报告

pytest框架编写的项目如何生成测试报告,这里将不再讲解,具体过程可以参考:pytest进阶之html测试报告

注意:python使用的allure插件为allure-pytest

目录结构

Allure特性

Environment

在Allure报告中添加环境信息,通过创建environment.properties或者environment.xml文件,并把文件存放到allure-results(这个目录是生成最后的html报告之前,生成依赖文件的目录)目录下

environment.properties

Browser=Chrome
Browser.Version=63.0
Stand=Production
ApiUrl=127.0.0.1/login
python.Version=3.6

或者

environment.xml

<environment>
    <parameter>
        <key>Browser</key>
        <value>Chrome</value>
    </parameter>
    <parameter>
        <key>Browser.Version</key>
        <value>63.0</value>

    <parameter>

        <parameter>
        <key>ApiUrl</key>
        <value>127.0.0.1/login</value>

        <parameter>
        <key>python.Version</key>
        <value>3.6</value>
    </parameter>
</environment>

执行run.py查看报告

Categories

测试报告默认统计两种类型的测试用例结果,失败的用例和故障测试用例,我们可以自定义添加用例的统计类型,同样需要在allure-results目录下新建categories.json文件

[
  {
    "name": "Ignored tests",
    "matchedStatuses": ["skipped"]
  },
  {
    "name": "Infrastructure problems",
    "matchedStatuses": ["broken", "failed"],
    "messageRegex": ".*bye-bye.*"
  },
  {
    "name": "Outdated tests",
    "matchedStatuses": ["broken"],
    "traceRegex": ".*FileNotFoundException.*"
  },
  {
    "name": "Product defects",
    "matchedStatuses": ["failed"]
  },
  {
    "name": "Test defects",
    "matchedStatuses": ["broken"]
  }
]

执行run.py查看报告

Fixtures and Finalizers

Fixtures和Finalizers是pytest在测试开始和测试结束调用的方法,allure会自动跟踪每一个fixture的调用,并且详细显示会调用哪些fixture和参数,而且会保留正确的调用顺数

测试代码

test_allure_html.py

def function_scope_step():
    print("function_scope_step")


def class_scope_step():
    print("class_scope_step")


def module_scope_step():
    print("module_scope_step")


def session_scope_step():
    print("session_scope_step")


def step_inside_test_body():
    print("step_inside_test_body")


@pytest.fixture(params=[True, False], ids=['param_true', 'param_false'])
def function_scope_fixture_with_finalizer(request):
    if request.param:
        print('True')
    else:
        print('False')

    def function_scope_finalizer():
        function_scope_step()

    request.addfinalizer(function_scope_finalizer)


@pytest.fixture(scope='class')
def class_scope_fixture_with_finalizer(request):
    def class_finalizer_fixture():
        class_scope_step()

    request.addfinalizer(class_finalizer_fixture)


@pytest.fixture(scope='module')
def module_scope_fixture_with_finalizer(request):
    def module_finalizer_fixture():
        module_scope_step()

    request.addfinalizer(module_finalizer_fixture)


@pytest.fixture(scope='session')
def session_scope_fixture_with_finalizer(request):
    def session_finalizer_fixture():
        session_scope_step()

    request.addfinalizer(session_finalizer_fixture)


class TestClass(object):

    def test_with_scoped_finalizers(self,
                                    function_scope_fixture_with_finalizer,
                                    class_scope_fixture_with_finalizer,
                                    module_scope_fixture_with_finalizer,
                                    session_scope_fixture_with_finalizer):
        step_inside_test_body()

执行run.py查看报告

@allure.step

pytest支持使用@allure.step修饰某些测试用例中需要的函数,使测试用例在allure报告中能够更加详细的显示测试过程

测试代码

test_allure_feature.py文件中修改如下代码

@allure.step("输入用户名")  
def input_username():
    print("输入用户名")


@allure.step("输入密码")
def input_password():
    print("输入密码")

执行run.py查看报告

conftest.py

@allure.step修饰的测试步骤还支持在conftest.py文件中定义,作为fixture的步骤,现在我们在项目目录下新建conftest.py文件,写入如下代码

conftest.py

@allure.step("打开浏览器")
def fixture_step():
    pass


@pytest.fixture
def init_url():
    fixture_step()
    yield True

test_allure_feature.py文件中添加如下用例

    def test_init_url(self, init_url):
        flag = init_url
        assert flag == True

执行run.py查看报告

allure.attach

使用allure.attach可以给报告中添加文件,图片,log,html代码等等。 我们修改test_allure_feature.py中如下用例, 并在用例所在目录添加attach.png图片

    def test_failed(self):
        """failed"""
        try:
            assert False
        except AssertionError as e:
            with open("attach.png", "rb") as f:
                context = f.read()
                allure.attach(context, "错误图片", attachment_type=allure.attachment_type.PNG)
            raise e

执行run.py查看报告

@allure.description

如果你想在报告中展示测试用例的描述信息,那么你可以使用@allure.description(string)或者@allure.description_html(html代码)修饰你的测试用例,test_allure_feature.py文件修改如下代码

    @allure.description("这是一个一直执行失败的测试用例")
    def test_failed(self):
        """你也可以在这里添加用例的描述信息,但是会被allure.description覆盖"""
        try:
            assert False
        except AssertionError as e:
            with open("attach.png", "rb") as f:
                context = f.read()
                allure.attach(context, "错误图片", attachment_type=allure.attachment_type.PNG)
            raise e

执行run.py查看报告

@allure.title

使用allure.title(title)可以重命名测试用例在allure报告中的名称,test_allure_feature.py文件修改如下代码

    @allure.title("登录成功场景-{data}")
    @pytest.mark.parametrize("data", login_success_data, ids=ids_login_success_data)
    def test_login_success(self, data):
        """测试登录成功"""
        user = input_username(data["user"])
        pwd = input_password(data["pwd"])
        result = login(user, pwd)
        assert result == data["expected"]

@allure.link

@allure.testcase

@allure.issue

这三种特性都可以给测试用例添加一个链接,test_allure_feature.py文件修改如下代码

    @allure.testcase("https://www.cnblogs.com/linuxchao/", "测试用例地址")
    def test_init_url(self, init_url):
        flag = init_url
        assert flag == True

    @allure.link("https://www.cnblogs.com/linuxchao/", name="bug链接")
    @allure.description("这是一个一直执行失败的测试用例")
    def test_failed(self):
        """你也可以在这里添加用例的描述信息,但是会被allure.description覆盖"""
        try:
            assert False
        except AssertionError as e:
            with open("attach.png", "rb") as f:
                context = f.read()
                allure.attach(context, "错误图片", attachment_type=allure.attachment_type.PNG)
            raise e

    @allure.issue("https://www.cnblogs.com/linuxchao/", "错误链接")
    def test_broken(self):
        """broken"""
        with open("broken.json", "r", encoding='utf8') as f:
            f.read()

执行run.py查看报告

 

 

 

@allure.feature

@allure.story

feature和story被称为行为驱动标记,因为使用这个两个标记,通过报告可以更加清楚的掌握每个测试用例的功能和每个测试用例的测试场景

在test_allure_feature.py文件中的测试类使用@allure.feature修饰, 测试方法使用@allure.story修饰

执行run.py查看报告

 以上两种标记不仅仅能够在测试报告中显示,而且还可以使用命令执行指定的测试模块或者场景

@allure.severity

此标记用来标识测试用例或者测试类的级别,分为blocker,critical,normal,minor,trivial5个级别,下面们把测试用例按级别标记,并查看一下测试报告

总结

以上就是所有的allure-pytest插件在pytest中支持的大部分功能特性,也许整理的不是很详细,所以如果你想详细的了解具体的特性在报告中的效果,还需自己动手尝试一下,附上本文参考链接
