9/10/2023 0 Comments Junit vs testng annotations![]() ![]() Each framework has differences and respective advantages. TestNG has a longstanding rivalry with another testing tool JUnit. Since version 4.6, TestNG also provides a reporter API that permits third-party report generators, such as ReportNG, The XML output can be transformed by the Ant JUnitReport task to generate reports similar to those obtained when using JUnit. TestNG generates test reports in HTML and XML formats. For later versions of Eclipse, TestNG must be manually installed as per instructions in the TestNG site. ![]() Note: TestNG support for Eclipse is only embedded in the Eclipse Marketplace for Eclipse versions up to 2018-09 (4.9). Most Java code coverage tools, such as Cobertura, work seamlessly with TestNG. The Hudson continuous integration server has built-in support for TestNG and is able to track and chart test results over time. It also comes with a custom task for Apache Ant and is supported by the Maven build system. TestNG is supported, out-of-the-box or via plug-ins, by each of the three major Java IDEs - Eclipse, IntelliJ IDEA, and NetBeans. This is particularly useful if you have a lot of parameter sets to pass to the method and you don't want to create all of them upfront. TestNG will invoke the iterator and then the test method with the parameters returned by this iterator one by one. The only difference with Object is that an Iterator lets you create your test data lazily. An array of array of objects ( Object) where the first dimension's size is the number of times the test method will be invoked and the second dimension size contains an array of objects that must be compatible with the parameter types of the test method.The returned type of a data provider can be one of the following two types: ( name = "provider1" ) public Object createData1 () This method will provide data to any test method that declares that its Data Provider is named "provider1". Distributed testing: allows distribution of tests on slave machines.Ī data provider in TestNG is a method in a test class, which provides an array of varied actual values to dependent test methods.Dependent methods for application server testing.Default JDK functions for runtime and logging (no dependencies).Embeds BeanShell for further flexibility.Concurrent testing: run tests in arbitrarily big thread pools with various policies available (all methods in their own thread, one thread per test class, etc.), and test whether the code is multithread safe.There isn't a TestSuite class, while test suites, groups and tests selected to run are defined and configured by XML files. TestNG can be run either by Ant via build.xml (with or without a test suite defined), or by an IDE plugin with visual results. Support for multiple instances of the same test class (with Flexible execution model.Support for data-driven/parameterized testing (with and/or XML configuration).The design goal of TestNG is to cover a wider range of test categories: unit, functional, end-to-end, integration, etc., with more powerful and easy-to-use functionalities. TestNG is a testing framework for the Java programming language created by Cédric Beust and inspired by JUnit and NUnit. ![]()
