magpie/internal/gui/tests/plugin-clash.test.cjs

// Run with Node's test runner and Playwright on the module path; see README.md.
// Two installed plugins that sign in to one provider (neiko on Discord: a
// third-party plugin and their own folder plugin both name it). Both rows
// stay, each says which one serves the provider, and the other one offers
// "Use for …", which tells magpie to run the provider on it. Neither row
// reads "Signs in to nothing magpie can use". Chromium and WebKit, every
// language, wide and narrow; the API is faked here.
