This was written a long time ago, the code may look a bit messy, just take a look ()
After all, writing this in java is not mainstream.
You need to add two package dependencies to the maven file first
Selenium mirror address (https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java)
TestNG mirror address (https://mvnrepository.com/artifact/org.testng/testng)
The code in the figure is as follows:
//Currently using the version with the most users, not the latest version of selenium
<dependencies>
<!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java -->
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>3.141.59</version>
</dependency>
//Using the 6.8.8 version of TestNG
<!-- https://mvnrepository.com/artifact/org.testng/testng -->
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>6.8.8</version>
<scope>test</scope>
</dependency>
</dependencies>
Then put the browser driver such as Chrome driver Chromedriver.exe (remember to check what version your Google browser is when downloading, if the version does not match, it is not applicable), place it in the newly created directory in the src file drivers (D:\java + selenium\src\drivers\chromedriver.exe) and then introduce chromedriver into the file.
In fact, the code of this piece is self-study based on the online class of station b, so there are many comments and it looks messy

File Upload
Divided into two cases: Similar to the following, use sendKeys to write the path of the file If the file upload is not an input element, but a third-party one controls. And it is not an input element, then this situation is very tricky, and some third-party tools, such as autoit, must be used to complete it.
chromeDriver, findElement(By.xpath("//input[@value='select file (value value)']")), sendKeys("Local file address, remember the escape of ");
Thread. sleep(2000);
chromeDriver.findElement(By.xpath("//input[@value='upload']")).click();
That’s about it. I’m going to introduce it with bricks. I may have written some things in a mess. Please forgive me.
