In this tutorial, we will learn how to toggle a boolean value in javascript. In addition to this, we will also learn how we can use it for various web application features that require toggling a certain piece of state or value. Toggling a boolean in JavaScript entails altering its value from true to false or vice versa. Toggling booleans can be helpful in a variety of situations, such as changing a boolean value to initiate an action or to toggle between states or the visibility of an element. Toggling can be implemented using different methods like the NOT operator, ... Read More
A TestNG class can have various TestNG methods. Such as: @BeforeTest @AfterTest @BeforeSuite @BeforeClass @BeforeMethod @test etc. As per execution order, @BeforeTest executes first and after that @BeforeMethod does. However, if there are multiple TestNG Tests inside a class, the behaviour of these methods is noticeable as @BeforeTest runs only once before the 1st @Test method runs but @BeforeMethod runs each time prior to the run of each @Test. @BeforeTest: This method will execute only once in entire execution before calling of 1st @Test method. It doesn’t matter how many @Test tag is present or how many classes ... Read More
In this post, we are going to learn how to set up an auto−size text area in JavaScript. This text area will be able to change its height automatically depending on the content within it. Auto−size text in JavaScript is a helpful feature that can be used to edit multiple lines of text. The text can automatically change its height depending on the content inside it. The default behavior of textarea doesn’t allow this, but we can create it by using the input event listener over it. Let’s understand how to adjust the height of the text area element dynamically ...

TestNG is a testing framework and can use Maven as build tool. It helps to maintain dependencies and their version at one place in pom.xml Maven provides flexibility to include or exclude a test group at run time. User can exclude test group or groups at run time in maven using surefire plugin. In this tutorial, we will illustrate how to exclude a test group via surefire at runtime. Approach/Algorithm to solve this problem Step 1: Create a TestNG classes −NewTestngClass Step 2: Write 2 @Test method in the class with group name. Step 3: Now create the ... Read More
This article will teach us how to use the Javascript location protocol properties to implement the web application's protocol. The read−only location.protocol property in javascript returns the protocol specified in the current webpage's URL. It offers details on the URL's protocol, including "http:", "https:", "file:", etc. Common protocol values that are utilised by numerous web apps include − http − It represents the Hypertext Transfer Protocol (HTTP). https − It represents the Hypertext Transfer Protocol Secure (HTTPS). file − It represents the File Transfer Protocol (FTP). ftp − It represents the File Transfer Protocol (FTP). data − It represents the data ...

Maven is a project management and comprehension tool that provides a complete build lifecycle framework. User can automate the project's build infrastructure in almost no time as Maven uses a standard directory layout and a default build lifecycle. In case of multiple environments, Maven can set−up the way to work as per standards in a very short time. As most of the project setups are simple and reusable, Maven makes life easy while creating reports, checks, build and testing automation setups. Maven provides developers ways to manage the following: Builds Documentation Reporting Dependencies SCMs Releases Distribution Mailing list ... Read More
In this post, we will discover how to use javascript's preventDefault and return false functions to override an event's default behaviour. The two most popular JavaScript methods for stopping an event's default behaviour are preventDefault() and return false. Let’s understand both of the concepts below − preventDefault() Return false The preventDefault() method is a function available on event objects in JavaScript Return false is not a function, but a javascript statement It helps to stop a certain event's default behaviour. It not only prevents the default behavior but also stops the event from ... Read More
Writing a test in TestNG basically involves the following steps − Write the business logic of the test and insert TestNG annotations in the code. Add the information about the test (e.g. the class name, the groups you wish to run, etc.) in a testng.xml file or in build.xml. Run TestNG. In this article, we will see one complete example of TestNG testing using POJO class, Business logic class and a test xml, which will be run by TestNG. Approach/Algorithm to solve this problem Step 1: Create EmployeeDetails.java in src, which is a POJO class as shown ... Read More
JUnit and TestNG are the most popular testing frameworks for Java applications. Both frameworks are easy to use. So, when it comes to choose the testing framework for your application, it’s better to have a high−level idea of what features are present in one or the other and then take the informed decision based on your project requirements. In this article, we will compare and contrast the different features of TestNG and JUnit. JUnit vs TestNG The following table compares JUnit vs TestNG on different features. The table excludes very specific or common features that are present in both these ... Read More
Testing is the process of checking the functionality of an application to ensure it works as per requirements. Unit testing comes into picture at the developer level where adequate measures are taken to test every single entity (class or method) to ensure the final product meets the requirements. What is Cucumber? Cucumber is a testing tool that supports Behaviour Driven Development (BDD) framework. It defines application behaviour using simple English text, defined by a language called Gherkin. Cucumber allows automation functional validation that is easily read and understood. Cucumber was initially implemented in Ruby and then extended to Java framework. ... Read More
