# c4t: Chrome for Testing - v1.6.0
Install _Chrome for Testing_ assets. A flavor of Chrome, specifically for testing and a matching chromedriver. Currently, the version of assets installed is for _linux64_ platforms only.
## Why Chrome for Testing?
Taken from [the Chrome Developers Blog](https://developer.chrome.com/blog/chrome-for-testing/)
> ...setting up an adequate browser testing environment is notoriously difficult...
>
> You want consistent, reproducible results across repeated test runs—but this may not happen if the browser executable or binary decides to update itself in between two runs.
>
>You want to pin a specific browser version and check that version number into your source code repository, so that you can check out old commits and branches and re-run the tests against the browser binary from that point in time.
>
> Not only do you have to download a Chrome binary somehow, you also need a correspondingly-versioned ChromeDriver binary to ensure the two binaries are compatible.
>
> Chrome for Testing is a dedicated flavor of Chrome targeting the testing use case, without auto-update, integrated into the Chrome release process, made available for every Chrome release
>
> ...finding a matching Chrome and ChromeDriver binary can be completely eliminated by integrating the ChromeDriver release process into the Chrome for Testing infrastructure.
## Requirements
To use Chrome for Testing assets you'll need a version of Selenium > 4.11.0

-l, --last-known-good-version
Install a last known good version from a list
```
#### Install the default, the latest stable version
```bash
# By default assets are installed in ${HOME}/.c4t-assets
# To use a different path, set the C4T_PATH_TO_ASSETS environment variable.
# e.g.: export C4T_PATH_TO_ASSETS=<path>
# Add this export to your .bashrc so the path is set for every bash session.
(venv) $ c4t install

(venv) $ c4t install --version 116.0.5794.0
```
#### Install a last known good version from a list
```bash
# Notice the list also indicates versions you already installed
(venv) $ c4t install -l
0 - Stable version=124.0.6367.91, revision=1274542, installed
1 - Beta version=125.0.6422.26, revision=1287751

Creating symlink to chromedriver version 116.0.5794.0
Active version is now: 116.0.5794.0
```
### Common workflow
1. Install one or more versions of Chrome for testing assets
1. Set/switch the active version
1. Run your Selenium Webdriver tests with the active version of Chrome for testing
E.g., this allows for quickly switching back to a previous version of Chrome to run your tests against in case of a regression on a recent/latest version. For example, a test failing against the latest of Chrome, did it pass consistently on the previous version or is it flaky and in need for a more robust implementation?
