User may encounter Cannot find class in classpath exception while executing tests in TestNG framework. The meaning of this error is TestNG unable to find the class as mentioned in testng.xml. This can be caused because of the following reasons − In the TestNG XML, the class tag having the name attribute. User should define the class name as . format. It should not have the .java extension. In the TestNG XML, the class file is incorrect and hence unable to determine the classpath of the class. Errors within the project are present and may require a clean project. ... Read More
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 run using surefire plugin. Surefire plugin has feature to pass parameter from command line to testng.xml. To achieve this, user should have to define parameter in testng.xml with default value. At run time, the user must send to parameter value to override default value. In this way, the value passed in command line take the preference and TestNG class uses it. If the value is not passed from command line, then ... Read More
TestNG allows to run the test suites from IntelliJ IDE as well as command line. When user run the testing.xml either from IDE or command line, TestNG generates a default report. It saves all reports and respective html files in Project −>test−output folder. If folder is not present, TestNG creates the folder. However, user can disable the default test report generation if they are using customized or external reporting mechanism. In this article we will evaluate how to disable the generation of default test reports: Disable while running through IntelliJ IDE Disable while running through command line Disable ... Read More
A TestNG class can have different tests like test1, test2, test3 etc. Once a user runs the TestNG class consisting of various tests, it runs the test cases in alphabetically order based on the name provided. However, user can assign the priority to these tests so that these tests can run as per user’s priority. Priority starts from 0 and be in incremental order. Priority 0 takes the highest priority and decreasing the priority when priority gets increase as 1, 2, 3 etc. In this article, let’s analyse how to control the order of execution in different ways. Scenario 1 ... Read More
Group test is a new innovative feature in TestNG, which doesn’t exist in JUnit framework. It permits you to dispatch methods into proper portions and perform sophisticated groupings of test methods Not only can you declare those methods that belong to groups, but you can also specify groups that contain other groups. Then, TestNG can be invoked and asked to include a certain set of groups (or regular expressions), while excluding another set. Group tests provide maximum flexibility in how you partition your tests and doesn't require you to recompile anything if you want to run two different sets of ... Read More

In Java, a file system is a hierarchical structure used to organize and store files and directories on a storage device. It provides a standard way to access and manipulate files and directories, regardless of the underlying storage device, such as a hard disk, USB drive, or cloud storage. Java provides the java.nio.file package, which contains classes and interfaces for working with file systems. The FileSystem interface represents a file system, and its FileSystems class provides factory methods for creating instances of FileSystem. You can check if a particular file system is open or not by using the FileSystem ... Read More
A numeric string in Python is a string that represents a numerical value using digits, signs, and decimal points, allowing for mathematical operations and data processing. In this article, we will learn a python program to increment numeric strings by K. Example Assume we have taken an input list of strings. We will now increment the numeric strings in an input list by k using the above methods. Input inputList = ["10", "hello", "8", "tutorialspoint", "12", "20"] k = 5 Output ['15', 'hello', '13', 'tutorialspoint', '17', '25'] In the above list, 10, 8, 12 20 are the numeric ... Read More
Finding the key of the maximum value tuples in a python dictionary means identifying the key associated with the tuple that has the highest value among all the tuples in the dictionary, which can be useful for retrieving the most significant or relevant information from the data. Example Assume we have taken an input dictionary having values as tuples. We will now find the key of maximum value tuples in an input dictionary using the above methods. Input inputDict = {'hello': ("p", 2), 'tutorialspoint': ("c", 15), 'python': ("k", 8)} Output The key of the maximum value in a ... Read More
In Python, a set is an unordered collection of unique elements, represented by {}. It allows efficient membership testing and eliminates duplicate values, making it useful for tasks such as removing duplicates or checking for common elements between sets. In this article, we will learn a python program to find the most common elements set. Methods Used The following are the various methods to accomplish this task: Using for loop and set.intersection() function Using list comprehension, max() and intersection() functions Demonstration Assume we have taken an input list containing sets. We will now get the most ... Read More
