File upload (sendKeys to input) in Selenium Java - Test Execution Trace

Test Overview

This test automates uploading a file by sending the file path to a file input element. It verifies that the file input contains the correct file path after upload.

Test Code - JUnit with Selenium WebDriver

Selenium Java

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.assertTrue;

public class FileUploadTest {
    private WebDriver driver;

    @BeforeEach
    public void setUp() {
        driver = new ChromeDriver();
        driver.manage().window().maximize();
    }

    @Test
    public void testFileUpload() {
        driver.get("https://example.com/upload");
        WebElement fileInput = driver.findElement(By.id("file-upload"));
        String filePath = System.getProperty("user.dir") + "/src/test/resources/sample.txt";
        fileInput.sendKeys(filePath);
        String uploadedFileName = fileInput.getAttribute("value");
        assertTrue(uploadedFileName.contains("sample.txt"), "Uploaded file name should contain 'sample.txt'");
    }

    @AfterEach
    public void tearDown() {
        if (driver != null) {
            driver.quit();
        }
    }
}

Execution Trace - 8 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Test framework initializes and prepares to run the test	-	PASS
2	Browser opens Chrome and maximizes window	Chrome browser window is open and maximized	-	PASS
3	Navigates to 'https://example.com/upload'	Upload page is loaded with a file input element having id 'file-upload'	-	PASS
4	Finds file input element by id 'file-upload'	File input element is located on the page	-	PASS
5	Sends file path to file input element using sendKeys	File input element now contains the file path string	-	PASS
6	Retrieves the value attribute of the file input element	Value attribute contains the uploaded file path	Check that the value contains 'sample.txt'	PASS
7	Assertion checks if uploaded file name contains 'sample.txt'	Assertion verifies the file input value	assertTrue(uploadedFileName.contains("sample.txt"))	PASS
8	Test ends and browser closes	Browser is closed and resources are cleaned up	-	PASS

Failure Scenario

Failing Condition: File input element with id 'file-upload' is not found or file path is incorrect

Execution Trace Quiz - 3 Questions

What Selenium method is used to upload a file in this test?

A sendKeys

B click

C submit

D getText

Key Result

Always verify the locator for the file input element is correct and the file path used in sendKeys is valid and accessible on the test machine.
