问题 Not able to return values from a Page object class function, where as same function is returns values through custom command. Custom command function: [This will return 10 texts] Cypress.Commands.add("defultPrelist", () => { cy.get('div[class="css-tpolag"]').then(function($elem) { const presetList_Name = $elem.text() return cy.wrap(presetList_Name) }) }) Main cypress driver class (where i need the custom function returned values) describe('Defult PresetsList Validation', function() { it(

Login to WordPress using Cypress, without using the UI

佐手、 提交于 2020-12-11 06:30:21
问题 In the Cypress-docs about logging in they state that one shouldn't setup the state using the UI. But it looks like that WordPress doesn't come with a login-possibility in the API. And since hacker-attacks are a problem on most WordPress-sites, then I would prefer not to add it. How do I log in to WordPress using Cypress, without using the UI? Update 2020-09-03 In case there is no way around this, then I'm just looking for the best way to do this. Is it to implement some hidden API-login

When developing e2e tests, Why is data-* attributes preferred for element selection over a plain id attribute

家住魔仙堡 提交于 2020-12-11 00:46:07
问题 Cypress and many other posts around testing web applications suggest relying on a data attribute like data-cy or data-test-id for locating elements rather than relying on the id attribute. My understanding is that for two reasons: The modern way of re-using the components can lead to having multiple components of same type and can lead to multiple of those Ids in the same page - But this should also apply to the 'data-cy' or 'data-test-id' attributes When Ids are tied to CSS, there is a

Cypress-自动化测试-语法

左心房为你撑大大i 提交于 2020-12-06 01:26:35
cypress在我的印象里,比selenium更易于理解。定位更准确,每一个步骤有生成快照,方便查看运行结果。 cypress和其他的UI自动化测试工具一样,最开始都要能够定位到界面元素。而定位界面元素的方法中,我印象中使用过xpath,坐标定位,document,但是往往界面的些许改动就容易影响代码的运行。所以cypress在这里做了一些改进。尽量避免界面元素定位失败。 1】cypress的元素定位   1、cy.get(selector) ,selector是DOM元素。 使用方法:   2、contains(content) contains(selector,content ) , content是DOM的文本内容 使用方法: 这里有一点需要注意的是,文本必须是当前页面的唯一值,当前页面有多个相同的文本值时,cypress只匹配第一个文本。   3、在定位列表中的字段时,可以使用cy.get('form>div>tr>td')的方式定位到第一行第一个值。   4、要定位的元素实在没有唯一值时,也可以根据上下文定位。比如cy.get(id).next() 可以定位到get('#id')元素的下一个元素。 cy.get('#id').children()定位到子元素。     cy. get('#id').children().first()定位到第一个子元素。 2】点击

How to set the browser's language in Cypress.io (electron/chrome)?

拟墨画扇 提交于 2020-12-01 09:49:26
问题 My question is about configuring Cypress to launch a browser instance in a certain language. In order to: make assertions on localized (i18n) text labels? check i18n features (switching between languages) bypass issues of Continuous Integration (CI/CD) when, for example, on a local computer, the browser default to fr_FR , and on the CI/CD VM it defaults to en_US ? I tried (without much success): using LANGUAGE=en_US from the terminal invocation, using the Browser's API plugin (see Cypress'

FLASH和EEPROM的区别

こ雲淡風輕ζ 提交于 2020-11-26 04:11:45
FLASH和EEPROM的最大区别是FLASH按扇区操作,EEPROM则按字节操作,二者寻址方法不同,存储单元的结构也不同,FLASH的电路结构较简单,同样容量占芯片面积较小,成本自然比EEPROM低,因而适合用作程序存储器,EEPROM则更多的用作非易失的数据存储器。当然用FLASH做数据存储器也行,但操作比EEPROM麻烦的多,所以更“人性化”的MCU设计会集成FLASH和EEPROM两种非易失性存储器,而廉价型设计往往只有FLASH,早期可电擦写型MCU则都是EEPRM结构,现在已基本上停产了。 至于那个“总工”说的话如果不是张一刀记错了的话,那是连基本概念都不对,只能说那个“总工”不但根本不懂芯片设计,就连MCU系统的基本结构都没掌握。在芯片的内电路中,FLASH和EEPROM不仅电路不同,地址空间也不同,操作方法和指令自然也不同,不论冯诺伊曼结构还是哈佛结构都是这样。技术上,程序存储器和非易失数据存储器都可以只用FALSH结构或EEPROM结构,甚至可以用“变通”的技术手段在程序存储区模拟“数据存储区”,但就算如此,概念上二者依然不同,这是基本常识问题。 没有严谨的工作精神,根本无法成为真正的技术高手。 现在的单片机,RAM主要是做运行时数据存储器,FLASH主要是程序存储器,EEPROM主要是用以在程序运行保存一些需要掉电不丢失的数据. 楼 上说的很好 另外,一些变量
