I want to run a certain function in cypress , even though they're all in the same file for example I have the below functions and want to run the create project one not all of them
or do they have to be in separate files
it('Create Project', ()=>{}
it('Create Customer', ()=>{}
it('Create Property', ()=>{}
it('Create Object', ()=>{}
If I understand your question, you want to be able to run only one test at a time. You can achieve this by using the .only function.
it.only('Create Project', ()=>{})
it('Create Customer', ()=>{})
it('Create Property', ()=>{})
it('Create Object', ()=>{})
see a better answer here: Cypress: run only one test
check cypress documentation here: https://docs.cypress.io/guides/core-concepts/writing-and-organizing-tests#Excluding-and-Including-Tests
