How to use the xml2js.parseStringPromise function in xml2js

export async function getFailures(log: ToolingLog, testReportPath: string) {
  const xml = await readAsync(testReportPath, 'utf8');

  // Parses junit XML files
  const report: TestReport = await xml2js.parseStringPromise(xml);

  // Grab the failures. Reporters may report multiple testsuites in a single file.
  const testSuites = 'testsuites' in report ? report.testsuites.testsuite : [report.testsuite];

  const failures: TestFailure[] = [];
  for (const testSuite of testSuites) {
    for (const testCase of testSuite.testcase) {
      const { failure } = testCase;

      if (!failure) {
        continue;
      }

      // unwrap xml weirdness
      const failureCase: TestFailure = {
        ...testCase.$,

export async function parseTestReport(xml: string): Promise {
  return await xml2js.parseStringPromise(xml);
}
