Maven is a build management system. The Maven wrapper can be used to install the right version of Maven. In this article, we will be learning about the wrapper and its benefits. Need for Maven Wrapper Normally, applications require specific Maven versions for the application to run successfully. So, developers need to ensure that the right Maven version is installed and available on the path. The Maven wrapper solves this issue. Using the wrapper, you just need to specify the desired Maven version. The wrapper then automatically installs the specified Maven version and makes it available on the path. Wrapper Installation Steps Let us first learn about the steps to install the wrapper. Open a command prompt/terminal window and navigate to the directory where you want to install the wrapper Run the following command: mvn -N io.takari:maven:wrapper 3. This command installs files related to the wrapper. So, you will see the following files/folders: .mvnw – This folder contains wrapper-spec

In this article, I will be explaining some of the important TestNG annotations. Introduction TestNG is a popular unit testing framework. It allows creating and running tests. Though largely inspired by JUNIT, it has many advanced features like generating HTML reports, running parametrized tests, and so on. One of the key features of TestNG is its ability to be configured via annotations. Annotations can be embedded within the TestNG code and help to control the flow of test execution. TestNG Annotations Let us now take a closer look at the TestNG annotations. @Test Designates a method as a TestNG test. Thus, you need to specify this annotation on any method that you want to run as a TestNG test. The @Test annotation has several attributes. Some of these are as follows: group: Specifies the group that the test belongs to. (TestNG allows creating test groups, so you can group related tests and run them in one go) description: Specifies the test description enabled: Specifies whether tes
