Spring Boot Web Application using Selenium WebDriver

You need to have an instance of WebDriver, e.g.:

@Beanpublic WebDriver webDriver() {    return new FirefoxDriver();    //OR return new ChromeDriver();}

in one of your configuration classes. That would be anything annotated with @Configuration or an annotation which includes this; in the most basic Spring Boot application (as used in Spring Boot examples), this would probably be something like this:

@SpringBootApplicationpublic class Application {    public static void main(String[] args) {        SpringApplication.run(Application.class, args);    }    // Your beans go here}

because @SpringBootApplication is annotated with @SpringBootConfiguration which is annotated with @Configuration.

package br.com.api.controller;import java.io.File;import java.io.FileOutputStream;import java.io.InputStream;import org.apache.tomcat.util.http.fileupload.IOUtils;import org.openqa.selenium.By;import org.openqa.selenium.WebDriver;import org.openqa.selenium.WebElement;import org.openqa.selenium.firefox.FirefoxDriver;import org.openqa.selenium.firefox.FirefoxDriverLogLevel;import org.openqa.selenium.firefox.FirefoxOptions;import org.springframework.core.io.ClassPathResource;import org.springframework.http.HttpStatus;import org.springframework.http.ResponseEntity;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@RestController@RequestMapping(value = "api/cenario/teste")public class TesteCenarioController {private WebDriver driver;@GetMappingpublic ResponseEntity<String> teste() {    setUpGeckoDriver();    FirefoxOptions options = new FirefoxOptions();    options.setLogLevel(FirefoxDriverLogLevel.TRACE);    options.setCapability("marionete", true);    this.driver = new FirefoxDriver(options);    System.err.println("DRIVER OK");    this.driver.get("https://www.phptravels.net/blog");    WebElement findElement = this.driver.findElement(By.xpath("//*[@id=\"body-section\"]/div/div/div[1]/div/div[1]"));    String testResult = "LATEST POSTS".equals( findElement.getText() ) ? "PASS" : "FAIL";    this.driver.quit();    return new ResponseEntity<String>(testResult, HttpStatus.OK);}private void setUpGeckoDriver() {    ClassPathResource classPathResource = new ClassPathResource("selenium/geckodriver.exe");    InputStream inputStream = null;    try {        inputStream = classPathResource.getInputStream();        File geckodriverFile = File.createTempFile("geckodriver", ".exe"); ;        FileOutputStream out = new FileOutputStream( geckodriverFile );        IOUtils.copy(inputStream, out);        System.err.println( geckodriverFile.getCanonicalPath());        System.setProperty("webdriver.gecko.driver", geckodriverFile.getCanonicalPath() );    } catch (Exception e) {        e.printStackTrace();    } finally {        IOUtils.closeQuietly(inputStream);    }}

}

On my resources directory I have selenium/geckodriver.exe.

My pom is the following:

I can start spring boot from eclipse than make a GET call to the url localhost:8080/api/cenario/teste. So Selenium open the browser and execute the test cenarios on demand, than I show the results on a web page.

But when I generate a jar file with the project, selenium fail to start the browser.
