UI automation test farewell from now on, manual download browser driver, recommended collection

Everyone is doing UI When automating , What is the most annoying , Is it element positioning or browser and driver compatible debugging ？ Let's move on

One .SeleniumWebDriver

SeleniumWebDriver Is a program that allows control Web Browser Library . It provides a cross browser API, Can be used to drive using different programming languages ( Such as Java、JavaScript、Python、C# or Ruby) Browser ( Such as Chrome、Edge or Firefox etc. ).Selenium WebDriver The main purpose of is to realize Web Automated testing of applications .

SeleniumWebDriver Use the native support of each browser to automate . For this reason , We need to use Selenium WebDriver API A browser named Driver Binary file . Now the drivers of mainstream web browsers are ChromeDriver (Chrome) ,geckoDriver (Firefox) , perhaps msededriver (Edge).WebDriver API The communication with the driver binary file is called W3C WebDriver( Formerly known as JSON Wire Protocol) The standard agreement of . then , Use the native function of each browser to complete the communication between the driver and the browser .

We manually download the corresponding version of the corresponding browser according to different browsers and browser versions driver, Set system properties .

System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
System.setProperty("webdriver.gecko.driver", "/path/to/geckodriver");
System.setProperty("webdriver.edge.driver", "/path/to/msedgedriver");
System.setProperty("webdriver.opera.driver", "/path/to/operadriver");
System.setProperty("webdriver.ie.driver", "C:/path/to/IEDriverServer.exe");

We're doing it UI When automating, we often encounter browser upgrades that lead to driver Version mismatch problem , The solution is to manually download the corresponding version driver, For starters , It's not a simple job , Is there any way to automatically download the corresponding version according to different browsers driver Well ？ The answer is yes , This is what we are talking about this time WebDriverManager. Yes Java and Python They all support it .

Two .WebDriverManager brief introduction

WebDriverManager It's an open source Java library , Of course, there are Python edition , It is executed in a fully automated way Selenium WebDriver Management of required drivers ( For example, download 、 Setup and maintenance ). in addition , In version 5 in ,WebDriverManager Other related functions are also provided , For example, find the browser installed in the local system , structure WebDriver object ( Such as ChromeDriver、FirefoxDriver、 EdgeDriver etc. ) , stay Docker The browser runs seamlessly in the container , And monitoring function .

3、 ... and .WebDriverManager actual combat (Java edition )

1.pom.xml Add WebDriverManager rely on

<dependency>
    <groupId>io.github.bonigarcia</groupId>
    <artifactId>webdrivermanager</artifactId>
    <version>5.0.3</version>
    <exclusions>
        <exclusion>
            <groupId>com.google.guava</groupId>
            <artifactId>guava</artifactId>
        </exclusion>
     </exclusions>
</dependency>

2. Create a new test script , To test the

import io.github.bonigarcia.wdm.WebDriverManager;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

/**
 * @author  author : The way test engineers grow up 
 * @version  Creation time ：2022/7/3
 *  Class description : Automatic download Chrome Browser driven 
 */
public class OperateBrowserDriver {

    public static void main(String[] args) throws InterruptedException {
        WebDriverManager.chromedriver().setup();
        WebDriver driver = new ChromeDriver();
        driver.get("http://www.cnblogs.com/mrjade/");
        Thread.sleep(1000);
        driver.quit();
    }
}

3. Execution results

4.driver Storage path ( With Macos For example )

Four .WebDriverManager actual combat (Python edition )

1. install

pip install webdriver-manager

2. Use
