Hard to distinguish data-drive tests/Provide placeholders support @Title

What is the current behaviour?

Allure 2 report shows data-driven tests by method name/or fixed title only:
No @Title

Using @Title

So, there is no quick way to distinguish data cases, one need to go through the list and click each case to see the difference.

If the current behaviour is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

1. Develop a data-drive test;
2. Ensure you have two and more data-cases for the test;
3. Run the test and generate report;
4. Have a look at the report.

What is the expected behaviour?

1. If there is no @Title then test method name + a short excerpt of the arguments' #toString() is shown in the list;
2. If there is @Title then the title's value is shown (current behaviour);
3. @Title supports placeholders in the same way as @Step:
   @Title("Check user {data.name }'s data.")
   or
   @Title("Check user's data - {0}.")

What is the motivation / use case for changing the behaviour?

A quick way to distinguish data-drive test executions in the report, no need to go through the list of executions to see the difference.

Please tell us about your environment:

• Allure version: 2.1.1
• Test framework: testng@6.10
• Allure adaptor: allure-testng@2.0-BETA10
• Generate report using: allure-maven@2.8

we can display test parameters in tree. Will it fix the problem?

Do you mean the approach used in Allure 1.* (methodName/Title + Paramaters[].toString())? If yes then it should work.
