Test method naming (ARCH3008)

Key typescript.naming.test-name-convention · Severity info · Category naming

Test functions should follow the test framework’s discovery and naming convention. Vague or inconsistent names hide the test’s intent and make failure output unreadable.

Incorrect

describe("UserService", () => {
  it("test1", () => {
    expect(svc.create(dto)).toBeDefined();
  });

  it("works", () => {
    expect(svc.find(99)).toBeNull();
  });
});

Correct

describe("UserService", () => {
  it("creates a user from a valid DTO", () => {
    expect(svc.create(dto)).toBeDefined();
  });

  it("returns null when the user is not found", () => {
    expect(svc.find(99)).toBeNull();
  });
});

Fix

Rename the test to a descriptive sentence stating the behavior and expected outcome.
