Command execution time very long

[stychu]

Why the command execution time takes almost double the time of the actual tests?
What is happening here?

Can I reduce somehow this timing?? I can't convince my coworkers if it takes so long to use cypress.

Tests execute in 1:16 whereas time that takes from the command (process) execution to finishing it takes 1:53... Is there something that I can do about it ?

Cypress Electron app takes time to start. Then during the run Cypress opens and closes a browser instance to run every spec. There is also a video encoding time after the spec.

can I instead enforce it doesnt close and reopen instance every run spec?

[bahmutov]

Unfortunately no. We do it to isolate the specs from each other.

Oh this is unfortunate. Will there be a configuration option to not restart the browser for each test spec in the future? Or it's not likely and you don't want to deal with possible bugs because of that?

No, we think isolating the browser for each spec file brings many advantages and makes tests less likely to depend on each other. I just want to add that if running test takes too long on a single machine, you can find ways to speed them up https://www.cypress.io/blog/2019/10/29/split-a-very-long-cypress-test-into-shorter-ones-using-app-actions/ or to run tests on CI in parallel https://on.cypress.io/parallelization
