You can see an example of configuring and using Cypress for UI testing with Batect in the Cypress sample project.
Much of the advice on the Node.js page also applies here.
Chrome uses IPC to communicate between its various processes. If your page is particularly complex, this can require a lot of
shared memory (often referred to as
shm), and if there isn't enough shared memory available, Chrome will simply crash.
By default, Docker will set a limit on shared memory of 64 MB, which usually isn't enough. You can increase this limit by setting
shm_size on the container that Cypress runs in.
There's more information available in this issue in the
Cypress repo. Note that setting
host is not required if
shm_size is set above its default.
