Method CompareEntries

Namespace: QueryGuard

Assembly: QueryGuard.Core.dll

CompareEntries(QueryGuardBaseline, IEnumerable<QueryGuardBaselineEntry>)

Compares recorded measurements against a baseline.

public static QueryGuardBaselineComparison CompareEntries(QueryGuardBaseline baseline, IEnumerable<QueryGuardBaselineEntry> measured)

Parameters

baseline QueryGuardBaseline: The recorded baseline. Empty is valid.
measured IEnumerable<QueryGuardBaselineEntry>: What each scope cost in this run.

Returns

QueryGuardBaselineComparison: The comparison.

Remarks

For measurements that did not come from a live run: read back from JSON reports, for instance, which is how the command-line tool works. An entry is what a comparison actually needs; a result is just a convenient thing to derive one from.

A separate name rather than an overload, because two overloads differing only in element type make Compare(baseline, []) ambiguous: a collection expression has nothing to infer from. The compiler caught that on the existing tests, which is a better place to find it than a user's build.

Scopes present in the baseline but absent from measured are ignored rather than reported as removed. A test run filtered to one project would otherwise claim every other endpoint had been deleted, and being wrong that loudly is worse than saying nothing.

Exceptions

ArgumentNullException: A required argument is null.
