在 Protractor 中模拟慢速打字

问题描述

sendKeys() 方法会一次发送所有密钥(实际上，一次一个，但非常快):

sendKeys() method would send all the keys at once (actually, one at a time but very quickly):

var elm = element(by.id("myinput"));
elm.sendKeys("test");

有没有办法减慢打字速度，以便 Protractor 一次发送一个字符，每个字符之间会有一点延迟?

Is there a way to slow the typing down so that Protractor would send one character at a time with a small delay between each of the characters?

我们可以完全减慢 Protractor，但这并不能改变 sendKeys() 的工作方式，它也会减慢一切，而我们只需要发送密钥"部分并且仅在特定情况下.

We can slow down Protractor entirely, but that does not change the way sendKeys() works and it would also slow everything down while we just need the "send keys" part and only in specific cases.

推荐答案

思路是使用browser.actions() 并构造一系列发送密钥"命令——一个字符串中的每个字符.在每个发送密钥"命令之后，我们通过引入 自定义 sleep动作.最后，这是我们提出的可重用函数:

function slowType(elm, keys, delay) {
    var action = browser.actions().mouseMove(elm).click();

    for (var i = 0; i < keys.length; i++) {
        action = action.sendKeys(keys[i]).sleep(delay);
    }

    return action.perform();
}

slowType(elm, "some text", 100);
