Support Different Modes

[Eraph]

Clear and concise description of the problem

I have joined a project where the Mode expected for running Vitest is vitest, for example, this NPM script from package.json:

vitest * --mode vitest

In this case, Vitest will look for the environment variable file .env.vitest. I would prefer not to have to rename this file as its use is already well established.

I can see that process.env.MODE is present and set to test, but overriding it in settings has no effect; perhaps it is being set after reading settings?

"vitest.nodeEnv": {
  "MODE": "vitest"
}

I can confirm that changing the filename to .env.test does allow it to be loaded.

Please provide a means to specify the mode used by the Vitest extension.

Suggested solution

Support a setting like the following:

"vitest.mode": "vitest"

Apply this value to the environment variable MODE, or continue to use the value test if not set.

You can assign a NODE_ENV env in vitest.nodeEnv or define the mode property in your config.

Thanks for the response, @sheremet-va. Unfortunately as I mentioned in the original post, I already tried to set MODE in vitest.nodeEnv, it looks like it is being ignored by the extension.

Which config are you referring to with regards to defining the mode property?

[sheremet-va]

Is there any reason why you won't just set mode in the config?

export default defineConfig({
  mode: 'vitest',
})

[Eraph]

Yeah, we're passing in the mode like this:

export default defineConfig(({ mode }) => {
  // Load env file based on `mode` in the current working directory.
  const env = loadEnv(mode, process.cwd());

So test could be a valid value, I would prefer not to overwrite it here.
