Issues writing unit test for z.cursor

Question

Hello,

I am trying to write a unit test on a trigger that calls z.cursor and the first issue I ran into was I need to set environment variables for ZAPIER_DEPLOY_KEY after doing that I get the following error:

only absolute urls are supported

which is referring to z.cursor.get() . Im guessing this is due to the fact that the function is using relative pathing but I am unsure how to move forward. Is there a way to mock out this call so that the test can continue?

Hi@Raman- If you’re using Jest to run your tests, try mocking the z.cursor.get and z.cursor.set functions before calling the trigger’s perform function. Here’s an example showing how I do it:// ...const originalPerform = App.triggers["your_trigger_key"].operation.perform;let cursor = "";App.triggers["your_trigger_key"].operation.perform = (z, bundle) => {  jest.spyOn(z.cursor, "set").mockImplementation(async (value) => {    cursor = value;    return null;  });  jest.spyOn(z.cursor, "get").mockImplementation(async () => cursor);  return originalPerform(z, bundle);};const response = await appTester(App.triggers["your_trigger_key"].operation.perform, bundle);// ...
