Can we Intercept a line of code similar to api request?

[ElamuruganGR]

Hi,

I am trying to mock window.location.pathname, I tried many approaches. In the cy.window() promise only the mock works(inside then). But when the testcase calls my actual function where window.location.pathname is used, its taking the cypress automated browser's pathname.

We use cy.intercept() to intercept a request so that whenever cypress encounters a http/https request with the same url, cy.intercept (...) will run and give the mock response.

My question is, Can we use cy.intercept() to intercept a single line of code lets say(window.location.pathname==="/") or (let x = a+b)so that whenever that particular line is executed by calling from the testcase, the mock from incept should be given.

Eg:

1) let x=a+b;

I always want x to be 10 whenever cypress encounters the above line
I want to mock this line with let x=10;

2) window.location.pathname==="/" ? execute1() : execute2();

I always want execute1() to run whenever cypress encounters the above line
i want to mock this line with execute1();
