Expand description
Easy temporary MongoDB instance for unit tests.
Use the TempMongo
struct to get a mongodb::Client
that is connected to a temporary MongoDB instance.
All state of the spawned MongoDB instance is stored in a temporary directory, which will be cleaned up automatically (unless disabled).
On Unix platforms, the client is connected over a Unix socket. Windows support is planned by picking a free TCP port on the loopback adapter.
§Example
See the example in the repository for a more detailed example using assert2
.
use temp_mongo::TempMongo;
use mongodb::bson::doc;
let mongo = TempMongo::new().await?;
println!("Using temporary directory: {}", mongo.directory().display());
let client = mongo.client();
let collection = client.database("test").collection("animals");
collection.insert_one(doc! { "species": "dog", "cute": "yes", "scary": "usually not" }, None).await?;
collection.insert_one(doc! { "species": "T-Rex", "cute": "maybe", "scary": "yes" }, None).await?;
