Selenium is focused on automating web applications for testing purposes, though definitely not on it alone. Administration tasks based on the Web can also be automated. It makes browsers automated
Automation testing uses automation tools to write and perform test cases, the implementation of an automated test suite requires no manual involvement. Testing prefer to submit check scripts and test cases using automation tools and then organize them into test suites.
Automation testing requires the usage of specialized tools to facilitate the implementation without any human involvement of manually crafted test cases. Automation testing tools may view test data, control test execution and evaluate the real result to the predicted outcome. Detailed test reports of the system under test are generated accordingly.
Any specific Automation testing advantages are as follows.
The following are examples of top 10 automation testing methods used for Functional Automation.
Lists of several commonly used Non-Functional Automation Research tools are as follows.
Selenium is a portable, software testing framework. Selenium tool facilitates the authoring of functional tests using a retrieval tool, without the need to know a language of test scripting.
Selenium is one of the most widely used testing suite for the implementation of open source Web UI (User Interface). At Thinking Functions, Jason Huggins invented selenium as an internal tool in 2004. Selenium facilitates development through various languages such as browsers, platforms and programming.
Selenium is not only a single tool but a series of software, each of which has a particular approach to support research automation. It comprises four main components including:
Selenium supports different operating systems, browsers, and languages. Here is the list:
There are different types of tests we can perform by Selenium.
Selenium IDE is implemented as an extension to Firefox which provides recording and playback functionality on test scripts. It enables testers to export recorded scripts in a variety of languages, including HTML, Java, Ruby, RSpec, Python, C #, JUnit and TestNG.
Selenium IDE has limited reach, and the test scripts produced are not very sturdy and portable.
Selenium commands, also known as "Selenese," are the set of commands that run your tests in selenium. For eg, in the specified browser, command-open (Link); launches the desired Link and accepts relative and absolute URLs.
A series of Selenium (Selenese) commands together is regarded as a test script.
Web components are identified and placed in Selenium, using Locators. In the context of a web application, locators specify a target location that defines the web element in a unique way. Therefore we have different types of locators in Selenium to classify web elements correctly and precisely:
The list of WebDriver API's which are used to automate browser include:
Selenium can be used to simplify functional testing, and it can be combined with automation testing techniques such as Maven, Jenkins, & Docker for continuous testing. It may also be combined with techniques like TestNG, & JUnit to handle test cases and generating reports.
The assertion acts as a point of verification. This verifies that the application condition is in keeping with what is expected. The statement types are "assert," "verified" and "waitFor ».
Assert: Assert control checks whether the condition given is true or false. If the condition is true, the control of the program will perform the next testing phase, and if the condition is false, the execution will stop and nothing will be executed.
Verify: Verify command often checks for valid or false condition. It does not stop execution of the program, i.e., any failure during verification would not stop execution, and all phases of the test would be executed.
Single Slash "/": Single slash is used to create XPath with absolute path.
Double Slash "//": Double slash is used to create XPath with the relative path.
JUnit annotations which can be used are:
WebDriver supported "mobile testing drivers" are:
Selenium WebDriver supports the below languages to write Test Cases.
The command "type" is used to enter key values into the software network application text box. This may also be used to select combo box numbers, whereas the command "typeAndWait" is used until the typing is complete and the reloading of the software web page starts. This command must wait to be reloaded to the software application page. If no page reload event occurs while typing, using a simple "type" command.
Selenium Webdriver incorporates the idea of the waits for the client dependent on AJAX. There are two kinds of warts:
Findelement(): It uses the specified "location mechanism" to find the first item within the current page. A single WebElement returns.
Findelements(): It uses the "location mechanism" provided to locate all of the elements inside the current page. It returns a list of elements within the web.
The Selenium Grid helps you to seamlessly spread the results on multiple machines and on all of them. Ok, you can use the same text file to run Internet Explorer checks on Windows and Safari on Mac machine. This reduces test time and offers fast feedback.
We need to create a driver instance of that particular browser.
WebDriver driver =newFirefoxDriver();
"WebDriver" is an interface here, so we're building a WebDriver-type reference variable "driver," instantiated with the "FireFoxDriver" class.
Implicit waiting main drawback is that it slows down test performance.
One other implicit disadvantage of waiting is:
Suppose you set the waiting limit to 10 seconds, and in 11 seconds the elements appear in the DOM, the tests would fail as you asked it to wait a maximum of 10 seconds.
The Automation Testing results are as follows.
Get command is used to get the web element specified inside text. The get command requires no parameters but returns a value of the string type. This is also one of the commonly used commands from web pages for verifying messages, labels, and errors, etc.
String Text = driver.findElement(By.id("Text")).getText();
We will use Action class to generate user event like right-click an element in WebDriver.
Actions action = newActions(driver); WebElement element = driver.findElement(By.id("elementId")); action.contextClick(element).perform();
Actions action = newActions(driver); WebElement element = driver.findElement(By.id("elementId")); action.moveToElement(element).perform();
Single Slash "/":Single slash is used to create XPath with absolute path.
Double Slash "//":Double slash is used to create XPath with the relative path.
XPath is often connected to XML Path. It is a term used to access documents using XML. The standardization of elements in Selenium is an important approach. XPath is an interpretation of the path, together with other conditions. Here we can compose XPath script / query easily to find some item on the webpage. It is developed to allow XML documents to be browsed. The main considerations it considers when exploring are the collection for particular handling of individual elements, attributes or some other aspect of an XML text. It's also developing accurate locators. Some other points concerning XPath are as follows.
