Setting test reporter testrun storage

[NavneetThekkumpat]

Test reporter Test run storage name is useful to differentiate each trx report if parsed or consumed by trx parsers. Currently it is set to hardcoded default value of Todo for every trx report generated. We need to change this from "Todo" to something meaningful and that can differentiate each test run.

Proposal

• Use the same trx file names used >> Results_{TestRunId} instead of Todo.
• This way it is easily identifiable and meaningful
