     * A template of the individual test case name.
     * This template can contain macros, which will be substituted by their actual values at runtime.
     * 

* Supported macros are: *

    *
  • {index} - index of parameters set (starts from zero). Hint: use it to avoid names duplication.
  • *
  • {params} - parameters set joined by comma.
  • *
  • {method} - testing method name.
  • *
  • * {0}, {1}, {2} - single parameter by index in current parameters set. * If there is no parameter with such index, it will use empty string. *
  • *
* Lets assume, that we are testing Fibonacci sequence generator. We have a test with the following signature *

     * {@literal @}Parameters({ "0,1", "8,34" })
     * public void testFibonacci(int indexInSequence, int expectedNumber) { ... }
     * 
* Here are some examples, that can be used as a test name template: *
    *
  • {method}({params}) => testFibonacci(0, 1), testFibonacci(8, 34)
  • *
  • fibonacci({0}) = {1} => fibonacci(0) = 1, fibonacci(8) = 34
  • *
  • {0} element should be {1} => 0 element should be 1, 8 element should be 34
  • *
  • Fibonacci sequence test #{index} => Fibonacci sequence test #0, Fibonacci sequence test #1
  • *
