CopyTestCasesFromRspec.ps1

# For each test case file in the RspecRulePath, copy the file to the OutputFolder with the name $FileName + $Scenario + $Extension
#
# The scenario is determined by the following rules:
# 1. The test case file name contains a dot, e.g. "MyTestCase.Scenario.razor"
#    Then the scenario name is the second part of the file name, e.g. "Scenario"
# 2. The test case file name contain a dot, but the test case file is in a subfolder, e.g. "MyTestCase\MyTestCase.Scenario.razor"
#    Then the scenario name is the second part of the file name, e.g. "Scenario", ignoring the folder name
# 3. The test case file name does not contain a dot, but the test case file is in a subfolder, e.g. "MyTestCase\Scenario.razor"
#    Then the scenario name is the file name, e.g. "Scenario", ignoring the folder name
# 4. The test case file name does not contain a dot and the test case file is in the root folder, e.g. "MyTestCase.razor"
#    Then the scenario name is empty, e.g. ""
# 5. In case of multiple test case files with the same scenario name, e.g. "MyTestCase1.Scenario.razor" and "MyTestCase2.Scenario.razor"
#    Then the scenario of the first file is "Scenario" and the scenario of the second file is "Scenario.1" and so on
#    This is to avoid overwriting the first file with the second file
#    This also applied to the other rules, e.g. "MyTestCase\MyTestCase.Scenario.razor" and "MyTestCase\Scenario.razor"
#
# Example:
#   1. MyTestCase.Scenario.razor            =>  RuleName.Scenario.razor
#   2. MyTestCase\MyTestCase.Scenario.razor =>  RuleName.Scenario.razor
#   3. MyTestCase\Scenario.razor            =>  RuleName.Scenario.razor
#   4. MyTestCase.razor                     =>  RuleName.razor
#   5. MyTestCase1.Scenario.razor           =>  RuleName.Scenario.razor
#      MyTestCase2.Scenario.razor           =>  RuleName.Scenario.1.razor
