1、关联：通常在业务流程中有很多一系列的接口调用，从前面的接口依赖前边接口的后果数据
from lxml import etreefrom locust import TaskSet, task, HttpUserclass UserBehavior(TaskSet): @staticmethod def get_session(html): tree = etree.HTML(html) return tree.xpath("//div[@class='btnbox']/input[@name='session']/@value")[0] \ @task(10) def test_login(self): html = self.client.get('/login').text username = 'user@compay.com' password = '123456' session = self.get_session(html) payload = { 'username': username, 'password': password, 'session': session } self.client.post('/login', data=payload)class WebsiteUser(HttpUser): host = 'http://debugtalk.com' # task_set = UserBehavior tasks = [UserBehavior ] min_wait = 1000 max_wait = 3000
2、检查点：用来判断返回值是否符合要求
from lxml import etreefrom locust import TaskSet, task, HttpUserclass UserBehavior(TaskSet): @staticmethod def get_session(html): tree = etree.HTML(html) return tree.xpath("//div[@class='btnbox']/input[@name='session']/@value")[0] \ @task(10) def test_login(self): html = self.client.get('/login').text assert "200" in html username = 'user@compay.com' password = '123456' session = self.get_session(html) payload = { 'username': username, 'password': password, 'session': session } self.client.post('/login', data=payload)class WebsiteUser(HttpUser): host = 'http://debugtalk.com' # task_set = UserBehavior tasks = [UserBehavior ] min_wait = 1000 max_wait = 3000
3、集合点：进步某个接口的并发度，当所有用户运行到指定地位后汇合期待，同时向下执行
from gevent._semaphore import Semaphorefrom locust import TaskSet, eventsfrom lxml import etreeall_locusts_spawned = Semaphore()all_locusts_spawned.acquire()def on_hatch_complete(**kwargs): all_locusts_spawned.release() # 创立钩子办法events.hatch_complete += on_hatch_complete # 挂载到locust钩子函数（所有的Locust实例产生实现时触发）class TestTask(TaskSet): def on_start(self): """ on_start is called when a Locust start before any task is scheduled """ all_locusts_spawned.wait() # 限度在所有用户筹备实现前处于期待状态 self.login() @staticmethod def get_session(html): tree = etree.HTML(html) return tree.xpath("//div[@class='btnbox']/input[@name='session']/@value")[0] \ def login(self): html = self.client.get('/login').text username = 'user@compay.com' password = '123456' session = self.get_session(html) payload = {'username': username, 'password': password, 'session': session} self.client.post('/login', data=payload)
