How do I open two browsers in Selenium?

To open two browsers in Selenium, you can achieve this by first initializing two separate WebDriver instances for each browser you intend to work with. Simply create a new WebDriver object for each browser, such as ChromeDriver and FirefoxDriver, and then you can interact with both browsers simultaneously in your test automation script.

For example, in Java code, you can open two browsers like this:

```java
WebDriver driver1 = new ChromeDriver();
WebDriver driver2 = new FirefoxDriver();
```

By setting up the WebDriver instances in this manner, you can effectively control multiple browsers in your Selenium automation tests.

In conclusion, opening two browsers in Selenium can be accomplished by creating distinct WebDriver instances for each browser you want to work with. This allows you to interact with multiple browsers concurrently and perform various test scenarios efficiently.
