#prefer-lowercase-title

#Configuration

import { defineConfig, rstestPlugin } from '@rslint/core';

export default defineConfig([
  rstestPlugin.configs.recommended,
  {
    rules: {
      'rstest/prefer-lowercase-title': 'error',
    },
  },
]);

Enforce lowercase test names.

Test and describe block titles should begin with a lowercase character. Uppercase initial letters are conventionally reserved for class names and named exports, not test descriptions.

#Options

This rule accepts an options object with the following properties:

#ignore

An array of strings specifying which functions to ignore. Valid values:

• "describe" — ignore all describe calls
• "test" — ignore all test calls
• "it" — ignore all it calls

#allowedPrefixes

An array of prefixes. A title that starts with any of these prefixes is ignored.

#ignoreTopLevelDescribe

A boolean, default false. When true, top-level describe blocks are not checked.

#ignoreTodos

A boolean, default false. When true, calls with a .todo member are ignored.

#Incorrect

test('Foo', function () {});
describe('Bar', function () {});

#Correct

test('foo', function () {});
describe('bar', function () {});
