Test skeleton

import { describe, expect, test } from "vitest";
import { add } from "./add";

describe("add", () => {
  test("a=0 (number) — TODO describe", () => {
    const result = add(0, /* b */);
    expect(result).toBeDefined();
  });

  test("a=-1 (number) — TODO describe", () => {
    const result = add(-1, /* b */);
    expect(result).toBeDefined();
  });

  test("a=Number.MAX_SAFE_INTEGER (number) — TODO describe", () => {
    const result = add(Number.MAX_SAFE_INTEGER, /* b */);
    expect(result).toBeDefined();
  });

  test("a=Number.NaN (number) — TODO describe", () => {
    const result = add(Number.NaN, /* b */);
    expect(result).toBeDefined();
  });

  test("a=Infinity (number) — TODO describe", () => {
    const result = add(Infinity, /* b */);
    expect(result).toBeDefined();
  });

  test("b=0 (number) — TODO describe", () => {
    const result = add(/* a */, 0);
    expect(result).toBeDefined();
  });

  test("b=-1 (number) — TODO describe", () => {
    const result = add(/* a */, -1);
    expect(result).toBeDefined();
  });

  test("b=Number.MAX_SAFE_INTEGER (number) — TODO describe", () => {
    const result = add(/* a */, Number.MAX_SAFE_INTEGER);
    expect(result).toBeDefined();
  });

  test("b=Number.NaN (number) — TODO describe", () => {
    const result = add(/* a */, Number.NaN);
    expect(result).toBeDefined();
  });

  test("b=Infinity (number) — TODO describe", () => {
    const result = add(/* a */, Infinity);
    expect(result).toBeDefined();
  });
});

使用方法

Type a TypeScript function signature into the input field。
Select the test framework: Vitest, Jest, or node:test。
Read the generated skeleton in the output area — it includes a describe block, an it block per expected behavior, and typed parameter stubs。
Copy the skeleton and paste it into your test file to fill in the assertions。

範例

Entering "function add(a: number, b: number): number" with Vitest selected generates a describe('add') block with an it('should return a number') stub and typed arguments。
Switching to Jest produces the same structure using jest.expect syntax instead of Vitest's。
