Using Since or Baseline, all mutations ignored despite code changes with mutations not killed using Azure Storage

[MrPDBennett]

We are trying to run mutations on only the changes in the branch using Since (and baseline earlier) and it is saying all mutations are ignored which is strange because I know the changed code definitely will have surviving mutations. We must be doing something wrong but can't work out what it is, it would be great if someone can point out what we are doing wrong

dotnet stryker --azure-fileshare-sas "xxxxxxx" --version feature/dhas-3647

stryker-config.json

In almost all cases this simply means that the remaining mutants are not covered by a unit test, or Stryker failed to discover test coverage for the mutants

[MrPDBennett]

Ah, OK, so we need at least one test to create a mutant. I suppose that is fairly obvious
