Basic Test Suite

This feature allows you to define a basic test suite using Jasmine's `describe` and `it` functions. The code sample demonstrates a simple test that always passes.

describe('Basic Test Suite', () => {
  it('should pass a basic test', () => {
    expect(true).toBe(true);
  });
});

Setup and Teardown

This feature allows you to run setup and teardown code before and after each test using `beforeEach` and `afterEach` functions. The code sample demonstrates how to use these functions.

describe('Setup and Teardown', () => {
  beforeEach(() => {
    // Code to run before each test
  });

  afterEach(() => {
    // Code to run after each test
  });

  it('should run setup and teardown', () => {
    expect(true).toBe(true);
  });
});

Matchers

This feature allows you to use various matchers to assert conditions in your tests. The code sample demonstrates the use of `toBe`, `toContain`, and `toEqual` matchers.

describe('Matchers', () => {
  it('should use matchers', () => {
    expect(1 + 1).toBe(2);
    expect([1, 2, 3]).toContain(2);
    expect({a: 1, b: 2}).toEqual({a: 1, b: 2});
  });
});
