jest/expect-expect Correctness

✅ This rule is turned on by default.

What it does

This rule triggers when there is no call made to expect in a test, ensure that there is at least one expect call made in a test.

Why is this bad?

People may forget to add assertions.

Example

it("should be a test", () => {
  console.log("no assertion");
});
test("should assert something", () => {});

This rule is compatible with eslint-plugin-vitest, to use it, add the following configuration to your .eslintrc.json:

{
  "rules": {
    "vitest/expect-expect": "error"
  }
}

How to use

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

CLI

oxlint --deny jest/expect-expect --jest-plugin

Config (.oxlintrc.json)

{
  "plugins": ["jest"],
  "rules": {
    "jest/expect-expect": "error"
  }
}
