Loadster is a simple-to-use, cloud based load testing platform, with an intuitive UI for building and running test scripts.
You can define steps, each of which is a call to your service, and check the responses for correctness. Several steps can be combined to form a script. Values can be extracted from responses for use as variables in later steps.
But what if you want to generate a value which isn't present in a response? There are some built in functions to create random numbers, but no obvious way to create GUIDs, for example.
This generates a GUID, and sets the
transaction_guid variable with the result.
Then you can use the variable in subsequent steps as you would any other variable in Loadster scripts:
