BaseTest class doesn't initialize the Webdriver instance - selenium-webdriver

Question

I have gone through similar type Q&As, but couldn't figure out the issue in my code.
This is my BaseTest class
`
package com.supportiveTests;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import io.cucumber.java.After;
import io.cucumber.java.Before;
public class BaseTests {
public static WebDriver driver;
#Before
public void setUpDriver() {
System.setProperty("webdriver.chrome.driver", "src/main/resources/Drivers/chromedriver.exe");
driver = new ChromeDriver();
}
#After
public void quitDriver() {
this.driver.quit();
System.out.println("done AfterTest");
}
}
`
This is my stepDefinition class (LoginPageSteps)
`
package com.stepDefinitions;
import com.pageObjects.LoginPage;
import com.supportiveTests.BaseTests;
import io.cucumber.java.en.Given;
import io.cucumber.java.en.Then;
import io.cucumber.java.en.When;
import org.testng.annotations.Test;
#Test
public class LoginPageSteps extends BaseTests {
LoginPage obj_login;
#Given("User is on Google Home page")
public void user_is_on_google_home_page() {
BaseTests.driver.navigate().to("https://www.google.com/");
}
#Given("User is navigated to SwagLabs Login page")
public void user_is_navigated_to_swag_labs_login_page() {
BaseTests.driver.navigate().to("https://www.saucedemo.com/");
}
#When("^User enters valid (.*) and (.*)$")
public void user_enters_valid_standard_user_and_secret_sauce(String username, String password) {
obj_login = new LoginPage(driver);
obj_login.enterUserName(username);
obj_login.enterPassword(password);
}
#When("clicks on LOGIN button")
public void clicks_on_login_button() {
obj_login.clickOnLogin();
}
#Then("User is navigated to SwagLAbs Home page")
public void user_is_navigated_to_swag_l_abs_home_page() throws InterruptedException {
BaseTests.driver.getCurrentUrl().contains("https://www.saucedemo.com/inventory.html");
Thread.sleep(2000);
BaseTests.driver.quit();
}
}
`
This is my TestRunner class
`
package com.supportiveTests;
import io.cucumber.junit.Cucumber;
import io.cucumber.junit.CucumberOptions;
import org.junit.runner.RunWith;
#RunWith(Cucumber.class)
#CucumberOptions(features = "src/test/Features",
glue = {"com/stepDefinitions"},
monochrome = true,
plugin = {
"pretty", "html:target/HTMLReports/report.html",
"json:target/JSONReports/report.json",
"junit:target/JUnitReports/report.xml"
}
)
public class TestRunner {
}
`
This is my pageObject class (LoginPage)
`
package com.pageObjects;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
public class LoginPage {
WebDriver driver;
public LoginPage(WebDriver driver) {
this.driver = driver;
}
By txt_username = By.xpath("//input[#id='user-name']");
By txt_password = By.xpath("//input[#id='password']");
By btn_login = By.xpath("//input[#id='login-button']");
public void enterUserName(String username){
driver.findElement(txt_username).sendKeys(username);
}
public void enterPassword(String password){
driver.findElement(txt_password).sendKeys(password);
}
public void clickOnLogin(){
driver.findElement(btn_login).click();
}
}
When the above TestRunner class is executed, I get this error
java.lang.NullPointerException: Cannot invoke "org.openqa.selenium.WebDriver.navigate()" because "com.supportiveTests.BaseTests.driver" is null
at com.stepDefinitions.LoginPageSteps.user_is_on_google_home_page(LoginPageSteps.java:16)
I went through the similar Q&As, where the solutions for driver initialization were provided, but couldn't figure out the issue. I am at basic level of Selenium testing framework, so appreciate any guidance on fixing this.
