11 Free Software Testing Trainings for Beginners

Softwares have become an inseparable part of our daily lives. The world demands intuitive, authentic and dependable technology, and in a rapidly growing market-place, even small negligence might result insomething disastrous. Software needs to be tested for bugs and to ensure the product meets the requirements and produces the desired results. Testing ensures premier user experience by eliminating weaknesses in software development. To be able to build high-quality scalable software, one has to think like a software tester.

Maven Tutorial for Selenium

While working on a project for test automation, you’d require all the Selenium dependencies associated with it. Usually these dependencies are downloaded and upgraded manually throughout the project lifecycle, but as the project gets bigger, managing dependencies can be quite challenging. This is why you need build automation tools such as Maven to handle them automatically.

Selenium Waits Tutorial: Guide to Implicit, Explicit, and Fluent Waits

Selenium waits for page load play an important part in your Selenium scripts. They help to make them less flaky and more reliable. Selenium provides multiple waits to provide adequate wait or pause in your script execution based on certain conditions. Thereby ensuring you don’t end up getting failed scripts as you perform automation testing with Selenium. In this tutorial, we will be explaining the types of Selenium waits and sleep, there real-time examples and a comparison study on them. Let us start by answering a pivotal question “Why should we use Selenium waits?”

TestNG tutorial

TestNG is a Java-based open-source framework for test automation that includes various test types, such as unit testing, functional testing, E2E testing, etc. TestNG is in many ways similar to JUnit and NUnit. But in contrast to its competitors, its extensive features make it a lot more reliable framework. One of the major reasons for its popularity is its ability to structure tests and improve the scripts' readability and maintainability. Another reason can be the important characteristics like the convenience of using multiple annotations, reliance, and priority that make this framework popular among developers and testers for test design. You can refer to the TestNG tutorial to learn why you should choose the TestNG framework.

Java debugging tool

You can extend a base class as others have suggested or you can use TestNG Guice dependency injection. e.g.:

TestModule.class

import com.google.inject.Binder;
import com.google.inject.Module;

public class TestModule implements Module {
    @Override
    public void configure(Binder binder) {
        BrowserLauncher bl = new BrowserLauncher();
        WebDriver driver = bl.launchBrowser("Firefox");
        binder.bind(WebDriver.class).toInstance(driver);
    }
}

BrowserFunctions.java

import com.google.inject.Inject;
import org.testng.annotations.AfterSuite;
import org.testng.annotations.BeforeSuite;
import org.testng.annotations.Guice;
import org.testng.annotations.Parameters;

@Guice(modules = {TestModule.class})
public class BrowserFunctions {
    @Inject
    WebDriver driver;

    @Parameters({ "URL" })
    @BeforeSuite
    public void invokeURL(String URL) {
        driver.get(URL);
    }

    @AfterSuite
    public void closeBrowser() {
        driver.close();
    }
}

Login.java

import com.google.inject.Inject;
import org.testng.Assert;
import org.testng.annotations.Guice;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;

import java.util.concurrent.TimeUnit;

@Guice(modules = {TestModule.class})
public class Login {
    @Inject
    WebDriver driver;
    StringBuilder sb = new StringBuilder();

    @Parameters({ "email", "password" })
    @Test
    public void logInTest(String email, String passowrd) {
        Assert.assertTrue(CommonFunctions.checkVisibility(driver, PageElements.amzUKsignInCTA), "Sign in CTA visible");
        CommonFunctions.clickButton(driver, PageElements.amzUKsignInCTA);
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        Assert.assertTrue(CommonFunctions.checkVisibility(driver, PageElements.amzUKEmailField), "Email field visible");
        CommonFunctions.inputToField(driver, PageElements.amzUKEmailField, email);
        Assert.assertTrue(CommonFunctions.checkVisibility(driver, PageElements.amzUKPasswordField),
                "Password field visible");
        CommonFunctions.inputToField(driver, PageElements.amzUKPasswordField, passowrd);
        Assert.assertTrue(CommonFunctions.checkVisibility(driver, PageElements.amzUKSignInButton),
                "Sign in button visible");
        CommonFunctions.clickButton(driver, PageElements.amzUKSignInButton);
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        Assert.assertEquals(driver.getCurrentUrl(), "https://www.amazon.co.uk/?ref_=nav_ya_signin&");
    }
}

etc.
