Pattern: Duplicate test title

Issue: -

Description

Using identical titles for different tests or test suites at the same level creates confusion when tests fail and makes it harder to identify which test needs fixing.

Examples

Example of incorrect code:

describe("suite", () => {
  it("should work", () => {
    expect(a).toBe(true);
  });
  
  it("should work", () => {
    expect(b).toBe(true);
  });
});

describe("feature", () => {});
describe("feature", () => {});

Example of correct code:

describe("suite", () => {
  it("should work with A", () => {
    expect(a).toBe(true);
  });
  
  it("should work with B", () => {
    expect(b).toBe(true);
  });
});

describe("feature A", () => {});
describe("feature B", () => {});
