Enum MutationRunner 

pub enum MutationRunner {
    Auto,
    Vitest,
    NodeTest,
    BunTest,
}

The test runner of fallow mutation.

Variants

Auto

Detect the runner from the project: the vitest dependency, the test module that the test files import, a Bun file at the root, or a node --test script.

Vitest

Vitest 4.1 to 5 from the project node_modules.

NodeTest

node:test of Node.js 22.18 or later. Each test file runs in its own Node process.

BunTest

bun test of Bun 1.4 or later. Each test file runs in its own Bun process.
