量角器 - 当元素不可见且不执行 "else" 条件时测试失败
Protractor - Test is failed when element is not visible and doesn't perform the "else" condition
我已经尝试 运行 一个流程 "if/else statement" 取决于某些元素是否可见。
但是如果这个元素不可见，它不会 运行 进入 "else condition" 并且所有测试用例都失败了。
请大家帮忙！谢谢。
测试用例：
it('New Client LiveSite - Payments - Perform a payment by PayPal', function () {
browser.wait(EC.visibilityOf(element(by.binding("buttonText"))), 30000);
element(by.binding("buttonText")).click();
var mainWindow;
browser.getAllWindowHandles().then(
function(handles) {
mainWindow = handles[0]; //at this point there should be only 1 window
}
);
browser.getAllWindowHandles().then(function (handles) {
handles.forEach(function(handle) {
if (handle !== mainWindow) {
browser.switchTo().window(handle)
var loadLogin = element(by.id("loadLogin"));
element.all(by.id('loadLogin')).then(function(){
expect(browser.driver.getCurrentUrl()).toContain('www.paypal.com');
browser.sleep(10000);
loadLogin.isDisplayed().then(function(result) {
if (result === true) {
loadLogin.click();
browser.driver.sleep(3000);
element(by.id("login_email")).sendKeys("username");
element(by.id("login_password")).sendKeys("pass");
browser.driver.sleep(1000);
element(by.id("submitLogin")).click();
browser.driver.sleep(5000);
element(by.id("submit.x")).click();
browser.driver.sleep(10000);
console.log("-=-=- first condition - I'm not logged-in -=-=-");
} else {
browser.driver.sleep(3000);
element(by.id("login_email")).clear();
browser.driver.sleep(1000);
element(by.id("login_email")).sendKeys("username");
element(by.id("login_password")).sendKeys("pass");
browser.driver.sleep(1000);
element(by.id("submitLogin")).click();
browser.driver.sleep(10000);
element(by.id("submit.x")).click();
browser.driver.sleep(10000);
console.log("-=-=- second condition - I'm already logged-in -=-=-")
}
});
});
}
});
});
browser.getAllWindowHandles().then(function (handles) {
browser.switchTo().window(handles[0]);
});
});

您似乎打算在切换新的 window 后与 loadLogin 元素进行交互，但您似乎也在尝试在切换前找到元素 loadLogin到 window。在测试开始时检查下面的代码。也许您需要切换到存在 loadLogin 元素的 window，然后查找它。
it('New Client LiveSite - Payments - Perform a payment by PayPal', function () {
var loadLogin = element(by.id("loadLogin"));
browser.sleep(2000);

当元素不可见时可能会抛出一些异常，这就是为什么您永远不会遇到 else 条件的原因。也许添加这样的东西，
loadLogin.isDisplayed().then(function(result) {
//keep your code here
}, function(err) {
console.log('Error occurred in loadLogin.isDisplayed:', err);
});
