testShorthands

Test cases with only a code property can use string shorthand syntax instead of object literal syntax.

✅ This rule is included in the flint logical presets.

When defining test cases for linting rules, if a test case only requires a code property without any additional configuration (like options, errors, etc.), it can be simplified using string shorthand syntax.

Examples

❌ Incorrect

ruleTester.describe(rule, {
  valid: ["a", { code: "a" }],
  invalid: [],
});

✅ Correct

ruleTester.describe(rule, {
  valid: ["a", "a"],
  invalid: [],
});

ruleTester.describe(rule, {
  valid: [
    { code: "a", fileName: "b.ts" },
    { code: "a", fileName: "c.ts" },
  ],
  invalid: [],
});

Options

This rule is not configurable.
