茉莉花toMatch方法无效

Question

试着测试时间格式。

实用程序js文件：

exports.getCurrentTime = function(s) {
    var now = new Date();
    var mins = lzero(now.getMinutes(), 2);
    var dateTime = ' ' + now.getHours() + ':' + mins;

    return dateTime;
};

规格类别：

utilities_spec.js

require("/tijasmine/tijasmine").infect(this);

//create suite, which has a collection of functions for testing
// class or just a slew of functions.
describe("utilities", function() {
    //import utilties class, so that we an access the functions.
    var utilities = require('utilities');

it("Get current time", function() {
    //matcher
    expect(utilities.getCurrentTime()).toMatch('^([0-1]?[0-9]|2[0-3]):[0-5][0-9]$');
});

获取以下错误：

 utilities Get current time. - Expected ' 23:41' to match '^([0-1]?[0-9]|2[0-3]):[0-5][0-9]$'.

如何成功地传递正则表达式？如果忽略正则表达式开头的引号，就会得到编译器错误。

Answer 1

我相信你真正想要的是/([0-1]?[0-9]|2[0-3]):[0-5][0-9]$/。

'([0-1]?[0-9]|2[0-3]):[0-5][0-9]$'是一个普通字符串，而不是正则表达式。
