Support for configuration variables

[veebs]

Requirement

• To have an external settings file that can be used to inject settings into the unit test case as it is run
• In order to support multiple platforms, it is best to use environment variables
• Example: https://github.com/xunit/xunit/issues/1908#issuecomment-524551069

New File Type

• default.env - default and can be source controlled
• local.env - overrides that may or may not be source controlled
• both files live in new 'config' folder as below image

{
  "settings": [
    {
      "name": "TestUser",
      "value": "jim"
    },
    {
      "name": "TestPassword",
      "value": "xxx"
    }
  ]
}

• Create editor for *.env
• Validate name - no spaces, does not start with a number, and only contains A-Z, a-z, 0-9, _, -
• Value does not require validation

Use of Settings

In the data column of test steps and routines, settings can be used as follows

{TestUser}

Code Generation

• For dotnet, create a static class that loads all the settings from then enviorment variable

  public static class EnvironmentSettings 
  {
    public static readonly string TestUser = Environment.GetEnvironmentVariable("TestUser");
  }

• For data values, replace {TestUser} with EnvironmentSettings.TestUser

• Generate a file based on the current OS to set the enviornment variable and then run dotnet test as per the above example

  • If linux, create run.sh and if windows, create run.bat
  • Create a run file for each of the env*.json file found
  • default.env -> run.default.env.sh
  • local.env -> run.local.env.sh

Running Tests

• On the run test dialog, add another dropdown to allow the user to pick the *.env file to use
• If there are no *.env file, do not show the drop down
