Java EE and JSF

[manimovassagh]

Hello everybody,
I am in a project that we use Java EE and JSF primefaces. because it has no rest API and is a fullstack java app , automatic cypress waiting most of the times failes and I have to explicitly give cy.wait() in End to End test for many cases. is there any solution that i be able to observe the DOM for stability and finished any update and then run the next line test?
for example I have a upload csv button and i give the file. how can i opberve the dom that when this is finished and dom is getting stable?
Thanks
