using ProtoScript.Runners; using ProtoScript.Testing; class Program { static void Main(string[] args) { ProtoScriptTestRunner runner = new ProtoScriptTestRunner(); TestResult results = runner.Execute("test.ps"); Console.WriteLine(results.Passed ? "All tests passed" : "Some tests failed"); } }In this example, we create an instance of the ProtoScriptTestRunner class and execute a test script named "test.ps". The results are stored in a TestResult object which we use to determine if all the tests have passed. Overall, the package library is used for testing ProtoScript files and ensuring that they function as intended.
