Selenium with JavaScript and Nodejs: How to count elements on page?

Question

I'm trying to use Selenium with Javascript (NodeJS) and I need to count some elements by CSS selector.

I tried several approaches:

client.findElements(By.css(".some-class")).size();

It gives me: Uncaught TypeError: client.findElements(...).size is not a function

client.findElements(By.css(".some-class")).Count();

It gives me: Uncaught TypeError: client.findElements(...).size is not a function

client.findElements(By.css(".some-class")).length;

Here length is always undefined.

What am I missing?

Thanks in advance.

findElements返回一个将解析为WebElements数组的promise。

client.findElements(By.css(".some-class")).then(elements => console.log(elements.length));
