Electron 10 and contextIsolation

[Coding-Kiwi]

Spectron has not been updated to work with Electron 10 in a timely manner, and it seems like it may soon lose its ability to work with Electron at all. The only way to use spectron in the future is in completely security-disabled environments which then do not show the real-world case of an app. Currently the problems are:

• electron 10
• contextIsolation: true
• enableRemoteModule: false

contextIsolation:

Every single application should have context isolation enabled and from Electron 12 it will be enabled by default.

From Electron Docs

enableRemoteModule

In Electron 10, the remote module is now disabled by default

From Breaking Changes

I think it should be time to come up with a solution. I think in order to make spectron work with electron 10 and contextIsolation, the api needs a proper contextbridge script in the preload.js

Confirmed. It's failing for me with:

Error: Failed to create session.
session not created: This version of ChromeDriver only supports Chrome version 83

For me it just opens tons of electron and cmd windows, I have to abort it to make it stop, no error messages

For me also opens tons of electron windows, and in the terminal I got that error

Just chiming in that I'm having the same issue with the hundreds of windows opening. After upgrading to 10 I had to set enableRemoteModule: true in my webPreferences. In case that's important.

@jkleinsc can you please have a look at this? we are still unable to use Electron 10 because of this :(

[jkleinsc]

Spectron unfortunately is written to use the remote module and setting contextIsolation: true and enableRemoteModule: false will make spectron unusable. As @AMDZEN3 mentioned you will need to set enableRemoteModule: true in the webPreferences setting in order to use Spectron.

Long term Spectron needs to be rewritten to not use the remote module.

@jkleinsc this workaround doesn't work to get Spectron running with electron 10 as there are a few other blockers, like the chromium webdriver version mismatch. Even with enableRemoteModule: True, and manually modifying the dependency chain of electron to use the proper chrome webdriver version, spectron still opens hundreds of windows and fails with errors.

Is there a plan to create a version of spectron (e.g. 12) that officially supports electron 10, at least until the remote module is completely deprecated?
