 | beforeEach | Presets a test-case-level action executed before each test case is executed. The number of execution times is the same as the number of test cases defined by it. You can pass the action function as the only parameter. | No |
 | afterEach | Presets a test-case-level clear action executed after each test case is executed. The number of execution times is the same as the number of test cases defined by it. You can pass the clear function as the only parameter. | No |
 | describe | Defines a test suite. You can pass two parameters: test suite name and test suite function. The describe statement supports nesting. You can use beforeall, beforeEach, afterEach, and afterAll in each describe statement. | Yes |

 Use the standard syntax of Jasmine to write test cases. The ES6 specification is supported.
