The -ignore-test-failures option determines whether any test failure will cause the mettleci compliance test command (docs) to generate a non-zero return code to the shell from which it was invoked.

In this case, use of the -ignore-test-failures option in an Azure pipeline would allows to allow the pipeline to continue past the point of the test execution, and then configure the step processing the JUnit XML test results to class test failures as Warnings (noteworthy, but acceptable to continue processing), or Errors (critical job failures: abort the pipeline)
