[turadg]

closes: #4722

Will be merged by squash.

Description

This upgrades Ava to version 4 (release notes).

Merging this will solve #4722. Example launch config:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "type": "pwa-node",
            "request": "launch",
            "name": "Debug AVA test file",
            "runtimeExecutable": "${workspaceFolder}/node_modules/.bin/ava",
            "runtimeArgs": [
              "${file}"
            ],
            "outputCapture": "std",
            "skipFiles": [
                "<node_internals>/**"
            ],
        }
    ]
}

However there are some outstanding hurdles:

• Ava dropped support for React
  • @samsiegart could the ui-components tests move to Jest?

Security Considerations

--

Documentation Considerations

Launch config should be added to #4418
