Answer a question

Actually I'm a bit confused. Although I read several resources about this.

For having a test of Selenium 3 using ChromeBrowser we need an extra app called ChromeDriver.

I found this text from GitHub:

ChromeDriver is only compatible with Chrome version 12.0.712.0 or newer. If you need to test an older version of Chrome, use Selenium RC and a Selenium-backed WebDriver instance.

My question is are all ChromeDriver versions compatible with all Chrome version? No conflict between each version?

Where can I find documentation of all versions matching between the ChromeDriver & ChromeBrowser?

There is general guide to select version of crhomedriver for specific chrome version: https://sites.google.com/a/chromium.org/chromedriver/downloads/version-selection

Here is excerpt:

• First, find out which version of Chrome you are using. Let's say you have Chrome 72.0.3626.81.
• Take the Chrome version number, remove the last part, and append the result to URL "https://chromedriver.storage.googleapis.com/LATEST_RELEASE_". For example, with Chrome version 72.0.3626.81, you'd get a URL "https://chromedriver.storage.googleapis.com/LATEST_RELEASE_72.0.3626".
• Use the URL created in the last step to retrieve a small file containing the version of ChromeDriver to use. For example, the above URL will get your a file containing "72.0.3626.69". (The actual number may change in the future, of course.)
• Use the version number retrieved from the previous step to construct the URL to download ChromeDriver. With version 72.0.3626.69, the URL would be "https://chromedriver.storage.googleapis.com/index.html?path=72.0.3626.69/".
• After the initial download, it is recommended that you occasionally go through the above process again to see if there are any bug fix releases.

Note, that this version selection algorithm can be easily automated. For example, simple powershell script in another answer has automated chromedriver updating on windows platform.
