export type RstestPoolOptions = {
  /** Pool used to run tests in. */
  type?: RstestPoolType;
  /** Maximum number or percentage of workers to run tests in. */
  maxWorkers?: number | string;
  /** Minimum number or percentage of workers to run tests in. */
  minWorkers?: number | string;
  /** Pass additional arguments to node process in the child processes. */
  execArgv?: string[];
};

export type RstestConfig = {
  /** Pool used to run tests in. */
  pool?: RstestPoolType | RstestPoolOptions;
};
      • Default:
      const defaultPool = {
  type: 'forks',
  // maxWorkers/minWorkers are computed from CPU count and command mode
};

      Options of pool used to run tests in.

      Example

      Shorthand

      You can use a string shorthand to set the pool type:

      rstest.config.ts
      import { defineConfig } from '@rstest/core';

export default defineConfig({
  pool: 'forks',
});

      This is equivalent to:

      rstest.config.ts
      import { defineConfig } from '@rstest/core';

export default defineConfig({
  pool: {
    type: 'forks',
  },
});

      Run all tests inside a single child process.

      rstest.config.ts
      import { defineConfig } from '@rstest/core';

export default defineConfig({
  pool: {
    type: 'forks',
    maxWorkers: 1,
    minWorkers: 1,
  },
});
