Disallow identical titles (no-identical-title)

Having identical titles for two different tests or test suites may create confusion. For example, when a test with the same title as another test in the same test suite fails, it is harder to know which one failed and thus harder to fix.

Rule Details

This rule looks at the title of every test and test suites. It will report when two test suites or two test cases at the same level of a test suite have the same title.

The following patterns are considered warnings:

describe('foo', () => {
  it('should do bar', () => {});
  it('should do bar', () => {}); // Has the same title as the previous test

  describe('baz', () => {
    // ...
  });

  describe('baz', () => {
    // Has the same title as a previous test suite
    // ...
  });
});

These patterns would not be considered warnings:

describe('foo', () => {
  it('should do foo', () => {});
  it('should do bar', () => {});

  // Has the same name as a parent test suite, which is fine
  describe('foo', () => {
    // Has the same name as a test in a parent test suite, which is fine
    it('should do foo', () => {});
    it('should work', () => {});
  });

  describe('baz', () => {
    // Has the same title as a previous test suite
    // Has the same name as a test in a sibling test suite, which is fine
    it('should work', () => {});
  });
});
