Tests using "@run testng" are compiled in the standard way,
with TestNG libraries on the classpath.
The test is run using the class org.testng.TestNG
.
For any TestNG test in a group of TestNG tests, any tests in the
group that need compiling are compiled together before any
test in the group is run.
Then, the selected test classes are run one at a time using
org.testng.TestNG
.
Each test that is run will have its results stored in a
corresponding *.jtr file.
