set an environment variable when running test from run button in VSCODE

I am creating some tests in Flutter, but I need to set an environment variable before running the tests. Is there a way to set an environment variable when running the app from these "Run | Debug" buttons?

Solution

  • With the new update to the Dart SDK it is possible: https://dartcode.org/releases/v3-11/

    [...] For example, to add CodeLens for a launch config that sets a RELEASE_MODE=true environment variable to tests in test/integration_tests:

    {
    "name": "Current File (release mode)",
    "type": "dart",
    "request": "launch",
    "codeLens": {
        // Types of CodeLens to inject
        "for": [ "run-test", "run-test-file", "debug-test", "debug-test-file" ],
        // Restrict to certain folders
        "path": "test/integration_tests",
        // Text for CodeLens link (${debugType} will be replaced with "run" or "debug")
        "title": "${debugType} (release)"
    },
    "env": { "RELEASE_MODE": true }
}

    This will insert additional CodeLens links into tests, groups and main functions:
