[TechCorner Challenge #1] Passing custom command-line arguments as test parameter
Hi Community!
This resource we are creating together has gained so much value over the years. Tons of helpful content can be found in the TestComplete Community thanks to all of you!
I propose that we take it to the next level by adding even more useful things to the TechCorner tag - a tag where we keep your tech articles, script examples, use cases, etc.
Here's your chance to share expertise and contribute.
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.
Difficulty:
For example, imagine that you have a web test that takes the name of the browser as a parameter. The script should check the command line TC was launched with, find the /BrowserName parameter, read its value, and pass it to the web test as a parameter. If the command line contains /BrowserName=chrome, the web test should launch Chrome; for /BrowserName=firefox the web test should launch Firefox, etc.
Good luck!

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.
