The Basics of Selenium

Before we get into the Selenium tutorial, let’s review some basics of Selenium itself. Selenium testing tools are comprised of Selenium IDE, Selenium WebDriver, and Selenium Grid.

• Selenium WebDriver — Browser-based driver that helps teams access and launch different browsers across different environments.
• Selenium IDE — An integrated developer environment that helps you record, edit, debug, and replay functional tests.
• Selenium Grid — Enables parallel testing on different machines against different operating systems and browsers, otherwise known as distributed test execution.

How to Use Selenium

Here are nine simple steps that break down how to use Selenium.

1. Install Selenium

2. Select a test framework

3. Apply real user conditions

4. Add Perfecto Connect

5. Instantiate web driver against the test environment

6. Add variables

7. Execute the tests

8. Review test results

9. Tag bugs in Jira

Advanced Selenium Tutorial

Learn how to run Selenium automated tests with Java and Quantum in Perfecto. Watch this advanced Selenium tutorial in step by step detail, or read below for a summary.

1. Install Selenium

First, you’ll need to install Selenium. You can download Selenium to get started.

2. Select a Test Framework

In the Eclipse IDE, start with a simple, responsive Java script. The one in our example tests the Boston Globe for availability within a particular zip code. For the test automation framework in this example, we’re using Quantum. Quantum is a BDD test framework and is Perfecto’s contribution to the open source community. So, here you have very simple Java inside of the Quantum framework.

Note that the creation of test automation scripts can be done with any framework you happen to be familiar with or any one that matches the skillsets of your automation or test engineers. For example, you can use code-based, codeless, or BDD frameworks depending on the skillsets of your team members. Whatever language your organization is familiar with, feel free to use that with the authoring of the test scripts.

3. Apply Real User Conditions

You can also apply real user simulation testing, which applies real test conditions to the test. You can test location, network coverage, and use of other applications in the background. Network virtualization allows you to get more accurate test results for the end user.

4. Add Perfecto Connect

You can also add a Perfecto Connect transport layer security tunnel to your test by adding the tunnel ID. This allows you to leverage Perfecto’s secure VPN.

5. Instantiate Web Driver Against the Test Environment

You can add a catch/try exception which comes into play if you fail to inquire about the browser selection. You can add some additional time outs to ensure your script takes screenshots from test to test, or from sections of the test.

6. Add Variables

You can opt to generate 4G LTE or a HAR file if desired. At this point you can enter in your variables which include the Boston Globe homepage in this example, the zip code, the selection of length, etc.

7. Execute the Tests

Next, run the script against your designated platforms. In this example, we’ve selected nine browser OS combinations to run against. With Perfecto, you can spin up nine virtual machines to run 198 test combinations across those various browser OS combinations, in the space of 15 minutes. See Perfecto’s supported platforms >>

8. Review Test Results

Once the tests are done, the Perfecto test lab releases the VMs and does a quick cleanup. Then, your subsequent test analytics are available inside of the report library.

With Perfecto, you can play back your tests to see what went wrong. You can play back the actual video capture itself, that you specified in your code. As the test flow is moving along, you get to see what's happening on the device as the test is running, even though the test has already concluded.

 You can also capture HAR files and the device log that shows CPU utilization, Wi-Fi network, and bytes in bytes out. All of the usual device logs and statistics are available there.

 9. Tag Bugs in Jira

As you examine your failed tests, you may need to send them back to your dev team. Fortunately, Perfecto has aJira integration which allows you to create a Jira ticket with the click of a button. That allows you to get the full traceability and issue tracking benefits of Jira with Perfecto.
