Request template

[siyu6974]

Description of feature request

It would be nice to have a template system to generate request data. For example, generating username, email...

Expected behavior

Store request templates in template/, load it by file name.

# locustfile.py
def register(self):
    self.client.post("/api/users", newUserObject())

# template.py
def newUserObject():
    usr = randomString()
    params = {"username": usr,
              "email": usr+"@test.com"}
    return makeRequestJson("createUserTemplate", params)

I already build such a system for my test, I can do a PR if needed.

i don't understand what this does or what benefit it gives you. Can you explain more?

[siyu6974]

The goal is to make the locustfile.py more compact. It offloads content creation to another file.
For example, to create a user object, we would have to

# locustfile.py
def register(self):
    usr = ''.join(random.choice(string.ascii_lowercase + string.digits) for _ in range(5))
    pwd = ''.join(random.choice(string.ascii_lowercase + string.digits) for _ in range(5))
    user = {""username": usr,
              "email": usr+"@test.com""
              "password": pwd}
    self.client.post("/api/users", user)

Things can get even messier if there are more fields.
What I propose is to have a folder storing templates files, like

/templates
    newUser.json
    newOrganisation.json

These templates file are just normal json with placeholder value, which can be easily acquired with a swagger or api explorer.

You can do it with faker lib.

faker lib is great to generate exemplary data but I'm talking about a request template: for example a json template for a REST api like you can have in Postman.
