Verify.MongoDB 3.0.23

Verify.MongoDB

Extends Verify to allow verification of MongoDB bits.

Verify.MongoDB is heavily inspired by @SimonCropp's Verify.EntityFramework

Enable

Enable VerifyMongoDb once at assembly load time:

VerifyMongoDb.Enable();

Recording

Recording allows all commands executed by the MongoDB driver to be captured and then (optionally) verified.

Call MongoDbRecording.EnableRecording() on MongoClientSettings.

var clientSettings = MongoClientSettings.FromUrl(new MongoUrl(configuration["MongoConnectionString"]));

clientSettings.EnableRecording();

By default, all three event types (Started, Succeeded and Failed) are recorded. You can optionally specify the events required.

clientSettings.EnableRecording(MongoDbEvents.Succeeded | MongoDbEvents.Failed);

EnableRecording should only be called in the test context.

Usage

To start recording call MongoDbRecording.StartRecording(). The results will be automatically included in the verified file.

MongoDBRecording.StartRecording();

await collection.FindAsync(Builders<BsonDocument>.Filter.Eq("_id", "blah"),
    new FindOptions<BsonDocument, BsonDocument>());
    
await Verifier.Verify("collection");

Will result in the following verified file:

{
  target: collection,
  mongo: [
    {
      Database: VerifyTests,
      Document: {
        filter: {
          _id: blah
        },
        find: docs
      },
      Type: Started,
      Command: find,
      StartTime: DateTimeOffset_1,
      OperationId: Id_1,
      RequestId: Id_2
    },
    {
      Document: {
        cursor: {
          firstBatch: [],
          id: 0,
          ns: VerifyTests.docs
        },
        ok: 1.0
      },
      Type: Succeeded,
      Command: find,
      StartTime: DateTimeOffset_2,
      OperationId: Id_1,
      RequestId: Id_2
    }
  ]
}
