let rally = require("rally"),
restApi = rally({
apiKey: 'mKxxxHRSqiC3ct6WsdJ1iyrxEhOtEyhl6cQyCBWic', //preferred, required if no user/pass, defaults to process.env.RALLY_API_KEY
apiVersion: 'v2.0', //this is the default and may be omitted
server: 'https://rally1.rallydev.com', //this is the default and may be omitted
requestOptions: {
headers: {
'X-RallyIntegrationName': 'Waas Test Consumer App UI Test', //while optional, it is good practice to
'X-RallyIntegrationVendor': 'Mastercard', //provide this header information
}
}
});

async function updateTestCaseResult(env: string, verdict: string, scenario) {
let testcaseId:string = await getTestCaseID(scenario)
if (testcaseId != null && browser.params.updateRally == true ) {
console.log("Test Case Update Started")
restApi.create ({
ref: "https://rally1.rallydev.com/slm/webservice/v2.0/testcase/" + testcaseId ,
data: {
type: 'TestCaseResult',
Build: env, //the data with which to update the specified object
Verdict: verdict,
Notes: "created using automation code",
scope: {
project: '/project/374073459708d'
