 ==== The TaskSet class ====
+=== Declaring tasks with the task decorator ===
+<code python>
+from locust import Locust, TaskSet, task
+class MyTaskSet(TaskSet):
+    @task
+    def my_task(self):
+        print "Locust instance (%r) executing my_task" % (self.locust)
+class MyLocust(Locust):
+    task_set = MyTaskSet
+</code>
+Or defining weight (task2 will be executed twice than task):
+<code python>
+from locust import Locust, TaskSet, task
+class MyTaskSet(TaskSet):
+    min_wait = 5000
+    max_wait = 15000
+    @task(3)
+    def task1(self):
+        pass
+    @task(6)
+    def task2(self):
+        pass
+class MyLocust(Locust):
+    task_set = MyTaskSet
+</code>
+=== Set an dictionary to tasks attribute ===
+The next dictionary will assign two tasks, each one with their weight.
+<code python>
+class MyTaskSet(TaskSet):
+    tasks = {my_task: 3, another_task:1}
+</code>
+=== The on_start function ===
+A TaskSet class can declare an on_start function. That function is called when a simulated user starts executing tasks in that TaskSet.
+=== Nesting TaskSets ===
+We can define a ''TaskSet'' as a task. Then it will represent a group of sub-task which are executed in that way.
+It could be useful to represent a user that makes actions over the web (like enter in a web, then browse films and watch one, then navigate in the blog and comment and comment again, then navigate again, then browse films...).
+A nested class set could call the ''self.interrupt()'' function. It interrupts the action in that class set.
+=== Nested sub-tasks examples ===
+<code python>
+class ForumPage(TaskSet):
+    @task(20)
+    def read_thread(self):
+        pass
+    @task(1)
+    def new_thread(self):
+        pass
+    @task(5)
+    def stop(self):
+        self.interrupt()
+class UserBehaviour(TaskSet):
+    tasks = {ForumPage:10}
+    @task
+    def index(self):
+        pass
+</code>
+<code python>
+class MyTaskSet(TaskSet):
+    @task
+    class SubTaskSet(TaskSet):
+        @task
+        def my_task(self):
+            pass

 ==== Hacer nuestro propio cliente ====
 Haremos un cliente "específico" para la tarea de deseemos. Este heredará de la clase ''Locust'' y usará el código que deseemos. Luego, para definir las acciones del test de carga heredaremos de esa clase; esta contendrá el taskset. Ver [[http://docs.locust.io/en/latest/testing-other-systems.html|aquí]], donde tenemos un código ''XmlRpcClient'' y una clase ''Locust'' que lo usa, la ''XmlRpcLocust''.
