]);

#Rule Details

Disallow the same title for two tests or two describe blocks in the same scope. Only static first arguments count (plain strings / simple templates); dynamic titles and *.each calls are ignored.

Examples of incorrect code for this rule:

describe("foo", () => {
  it("bar", () => {});
  it("bar", () => {});
});
describe("x", () => {});
describe("x", () => {});

Examples of correct code for this rule:

describe("foo", () => {
  it("a", () => {});
  it("b", () => {});
  describe("foo", () => {}); // same as parent name, different scope
});
test("x" + n, () => {});
test("x" + n, () => {}); // not static — skipped
