Jasmine

describe(string,function)　　//suite测试集，可包含多个Specs(it)，每个Specs(it)可包含多个expect

describe("A suite", function() {
  it("contains spec with an expectation", function() {
    expect(true).toBe(true);
  });
});

beforeAll,beforeEach,afterAll,afterEach　　//beforeAll：每个suite（即describe）中所有spec（即it）运行之前运行, beforeEach：每个spec（即it）运行之前运行

(function(){
    describe("Test 'this'", function() {
      beforeEach(function() {
        this.testCount = this.testCount || 0;
        this.testCount++;
      });

      afterEach(function() {
        //this.testCount = 0; //无论是否有这行，结果是一样的，因为this指定的变量只能在每个spec的beforeEach/it/afterEach过程中传递
      });
