  <pre><code>       public virtual void SearchAPICalledWithMissingParameter()

              TechTalk.SpecFlow.ScenarioInfo scenarioInfo = new TechTalk.SpecFlow.ScenarioInfo("Search API called with missing parameter", new string[] {
                          "search"});
  #line 8
  this.ScenarioSetup(scenarioInfo);
  #line 9
   testRunner.Given("I call Search API without parameter", ((string)(null)), ((TechTalk.SpecFlow.Table)(null)), "Given ");
  #line 10
   testRunner.When("I get the response back from API", ((string)(null)), ((TechTalk.SpecFlow.Table)(null)), "When ");
