jest/no-standalone-expect Correctness

✅ This rule is turned on by default.

What it does

Prevents expect statements outside of a test or it block. An expect within a helper function (but outside of a test or it block) will not trigger this rule.

Statements like expect.hasAssertions() will NOT trigger this rule since these calls will execute if they are not in a test block.

Example

describe("a test", () => {
  expect(1).toBe(1);
});

How to use

To enable this rule in the CLI or using the config file, you can use:

CLI

oxlint --deny jest/no-standalone-expect --jest-plugin

Config (.oxlintrc.json)

{
  "plugins": ["jest"],
  "rules": {
    "jest/no-standalone-expect": "error"
  }
}
