[TechCorner Challenge #1] Passing custom command-line arguments as test parameter

Task: Write a script that will take the value of a custom argument from the TC command line and use this value to run a parameterized test.

This is a solution created for [TechCorner Challenge #1]

My  way ..

// The object we'll populate
var cmdRun = {
   exec   : "",
   params : [],
   count  : 0
};

function BuildCmdParams() {
   // Get executable name, which is always ParamStr(0), a so old MS-DOS rule ...
   cmdRun.exec = BuiltIn.ParamStr(0);
   // Beware, the ParamCount() method returns 0 if no additional parameter and btw ignore the real ParamStr(0) !
   // But if parameter(s) exists you should loop to one more because in this case the param 0 exists ... quite strange yes ..
   cmdRun.count = BuiltIn.ParamCount();
   Log.Message("The executable file is '" + cmdRun.exec + "' and it has " + cmdRun.count.toString() + " parameter" + cmdRun.count == 0 ? "" : "s");
   if (cmdRun.count != 0) {
      cmdRun.count++;
      for (let i = 0; i < cmdRun.count; i++) {
         cmdRun.params[i] = BuiltIn.ParamStr(i);
         Log.Message("Param " + i.toString() + " = '" + cmdRun.params[i] + "'");
      }   
   }   
}

function GetCmdParamsValue(ParamName = "") {
   result = "";
   if ((ParamName == "") || (cmdRun.count == 0))
      return result;
   for (let i = 0; i < cmdRun.count; i++)
      // To avoid the false positive if a param name is also a param value somewhere, check that the param name is well at beginning, ignoring the / and ignoring also character case
      if (aqString.Find(cmdRun.params[i], ParamName, 0, false) == 1) {
         // Here you can use a aqString.Find of the separator character or a split .. upon your choice. For the example, i use a split and assuming separator is =, so index 0 is name of parameter, index 1 is value of parameter
         result = cmdRun.params[i].split("=")[1];
         break;
      }
   return result;
}

function TestIt() {
   BuildCmdParams();
   Log.Message("The value of BrowserToUse is " + GetCmdParamsValue("BrowserToUse"));
}

The cmd line is :

TestComplete.exe "C:\Users\Public\Documents\TestComplete\Apex\Apex.pjs" /r /p:DataFeed /BROWSERTOUSE=Firefox /ns /e

The result is :

The production code without comments/log :

var cmdRun = {
   exec   : "",
   params : [],
   count  : 0
};

function BuildCmdParams() {
   cmdRun.exec  = BuiltIn.ParamStr(0);
   cmdRun.count = BuiltIn.ParamCount();
   if (cmdRun.count != 0) {
      cmdRun.count++;
      for (let i = 0; i < cmdRun.count; i++) 
         cmdRun.params[i] = BuiltIn.ParamStr(i);
   }   
}

function GetCmdParamsValue(ParamName = "") {
   result = "";
   if ((ParamName == "") || (cmdRun.count == 0))
      return result;
   for (let i = 0; i < cmdRun.count; i++)
      if (aqString.Find(cmdRun.params[i], ParamName, 0, false) == 1) {
         result = cmdRun.params[i].split("=")[1];
         break;
      }
   return result;
}

You can improve it into putting it all in object style notation.
