javascript - Jasmine beforeeach 与变量等于值的区别

Question

谁能告诉我下面的 Jasmine 代码的区别，如果很愚蠢请原谅我

describe('Testing a Hello World controller', function() {
    var $scope;

    beforeEach(function(){
        $scope = 'Hello World'
    });

    it('should say hello to the World', function() {
        expect($scope).toEqual('Hello World');
    });
});

并且

describe('Testing a Hello World controller', function() {
    var $scope = 'Hello World';

    it('should say hello to the World', function() {
        expect($scope).toEqual('Hello World');
    });
});

Answer 1

无，因为每个描述中只有一个测试，请尝试以下操作:

describe('beforeEach example', function() {
        var $scope = 0;

        beforeEach(function(){
            $scope += 1
        });

        it('should be 1', function() {
            expect($scope).toEqual(1);
        });

        it('should be 2', function() {
            expect($scope).toEqual(2);
        });
    });
