I wanted to compile my tests once, and then have a flexible runtime that lets me invoke subsets of tests-such as running database tests only, or fast tests only-without having to recompile anything. As a result, most developers resort to commenting out test or suite methods. JUnit also does not provide an easy way to pass parameters to each test method.Īs well, JUnit forces you to recompile your tests when you want to run different sets of tests. That's because JUnit re-instantiates your objects from scratch between each call, forcing you to use statics to maintain state. In general, poor configuration control in JUnit also means that there is no easy way to maintain state between invocation calls. An example of class-level setup is when you need to create an expensive object for the duration of a test. Thus, while I found it easy to test classes with JUnit, when it came to testing full applications or entire systems, JUnit didn't offer a lot of flexibility.įor instance, setUp() and tearDown() methods are useful to configure test methods, but I often found the need to do similar initialization around test classes or around test suites. Unit testing is an important part of testing, but there are other aspects of testing that I thought JUnit didn't make easy, such as regression, integration, or functional testing. What I mean by unit testing is testing a class in isolation of all other classes. What do you mean by next-generation testing, and what problems does TestNG address that are not also addressed in JUnit?Ĭédric Beust: JUnit was explicitly designed for unit testing. This interview took place over email, and Artima edited the replies for readability.įrank Sommers: You describe TestNG as a next-generation testing framework. In addition to creating TestNG, Cédric Beust is a senior engineer at Google, and is an active member of the Java Community Process (JCP), having been involved in various aspects of the development of the latest Java release. In this interview, he shares what he considers common misconceptions about unit testing, what JUnit deficiencies led him to write TestNG, and how TestNG helps work with a large number of unit tests. On that occasion, Artima spoke with TestNG creator Cédric Beust about unit testing and TestNG. TestNG, an open-source Java unit testing tool, was created to overcome JUnit's key limitations, and to provide additional features needed to test the latest generation Java applications. While JUnit pioneered Java unit testing, and still remains the most popular Java testing tool, JUnit also comes with many limitations that impose restrictions on developers' testing habits. He also explains the benefits of data-driven testing, and provides a preview of some new TestNG features. In this interview with Artima, TestNG creator Cédric Beust describes what JUnit deficiencies TestNG aims to solve, and talks about some common unit testing misconceptions, including the dangers of overt focus on obtaining complete test coverage. This is just work around I am not sure if this is the best approach but as of now solving my purpose package is a Java unit testing framework that aims to overcome many limitations of JUnit. Some how i have figured the solution ,we can still get the testName of the test method using two listners ,First of all you are correct in explaining use of TestNG but we are using TestNG for Selenium and already there are around 1000 test cases writen in test Methods and we have to live with that
