There might be other unit testing frameworks available which maybe better than TestNG but for me coming from a JUnit test framework background it was easy to adapt to TestNG (which has got inspiration from JUnit and NUnit). The requirement I had was to have a test framework where it was:
- Easy to pass data as parameters to the test from a resource file
<test name=”testElement”>
<classes>
<class>
<parameter name=”element” value=”LKG”/>
</class>
</classes>
</test>@Parameters(value= {“element”})
@Test
public void testElement(String element) {//same Assert statements as in JUnit
}
- Easy to configure in a big project (one resource file for each corresponding Test File) and the main Suite to run all the tests
<suite name=”MainTestSuite”>
<suite-files>
kentor/TestElement.xml” />
</suite-files>
</suite>
- Do things that I could do with JUnit like testing expected exceptions
@Test(expectedExceptions = ArithmeticException.class)
public void divisionWithZeroException() {
int i = 1/0;
}
- IDE Support (Eclipse, Netbeans). Inbuilt in Netbeans latest versions.
- Generating various types of reports
- Integrating with Maven and few more…
It is only a matter of starting to use TestNG and you would know how ease it is to write Unit test with this library. More could be read on the documentation where a lot is talked about grouping the tests, using DataProviders (instead of parameter passing), running test parallel, Creating factory classes and reporting
