菜鸟问题.我正在使用 webdriver.io 编写 Appium 端到端测试.
Rookie question. I am using webdriver.io to write Appium end to end tests.
我正在使用以下命令来检查元素的存在:
I am using these commands to check the presence of an element:
- $(selector)
- browser.waitForVisible(selector, timeout, waitForAppearOrDisappear);
- browser.element('selector')
- $(selector)
- browser.waitForVisible(selector, timeout, waitForAppearOrDisappear);
- browser.element('selector')
如果找不到该元素,它们都会阻止我的测试.
They all block my tests if the element is not found.
如何在不阻止测试执行的情况下检查元素在特定时刻是否存在?
How can I check whether an element exists in a particular moment without blocking the test execution?
(简洁的)文档中找不到任何内容.
I cannot find anything in the (concise) documentation.
PS. browser.findElement(By.css('[data-qa="some-id"]'));应该可以解决问题,但这不是 wdio 命令. (无法识别findElement和By)
PS. This should do the trick browser.findElement(By.css('[data-qa="some-id"]')); but it's not a wdio command. (findElement and By are not recognized)
npm依赖项:
"appium": "^1.10.0", "appium-doctor": "^1.6.0", "wdio-appium-service": "^0.2.3", "wdio-jasmine-framework": "^0.3.8", "wdio-spec-reporter": "^0.1.5", "webdriverio": "^4.14.1",推荐答案
好吧,简单的方法是滥用查询Selenium服务器的事实(使用 $ / 元素 )是不间断的操作.
Well, the simples way would be to abuse the fact that querying the Selenium server (using $ / element) is a non-breaking operation.
假设您必须查询2个元素,一个元素已在DOM中呈现,另一个元素不存在(或该元素根本不存在).
Suppose you have to query 2 elements, one has rendered inside the DOM, the other didn't (or the element doesn't exist altogether).
let thisLoaded = $('span.coreSpriteFacebookIconInverted'); let thisDidnt = $('span.coreSpriteInstagramIconInverted');这两个变量将具有以下内容:
The two variables would have the following contents:
thisDidnt = { sessionId: '7056961e1950b5c54827a51c137cca96', value: { ELEMENT: '0.8611270215748772-1', 'element-6066-11e4-a52e-4f735466cecf': '0.8611270215748772-1' }, selector: 'span.coreSpriteFacebookIconInverted', _status: 0 } thisDidnt = { type: 'NoSuchElement', message: 'An element could not be located on the page using the given search parameters.', state: 'failure', sessionId: '7056961e1950b5c54827a51c137cca96', value: null, selector: 'span.coreSpriteInstagramIconInverted' }因此,您现在可以继续进行检查了...
Thus, you can now proceed to do your checks ...
if (thisLoaded.value) { // > if element loaded < } else { // > if element didn't load < }
我回到家时会添加更多...
I'll add more when I get home ...
